“SS-H”PRESSURE SWITCH OPERATION MANUAL (4HL2/4HH2) 3/01 1.0 INTRODUCTIONThe Ruelco “SS-H” hydraulic pressure switch is a two way bleed valve which is operated by pressure acting on a piston opposing an adjustable spring force. It functions as either a normally closed or normally open valve. Pressure applied to the sense port will cause the valve to operate.The Model 4HH2 operates as a normally open valve and is called a high switch. If sense pressure acting on the piston is at normal levels, it is insufficient to overcome the spring force. The middle o-ring on the spool is positioned below the bent grooves on the bottom sleeve, thus preventing the instrument pressure from passing to the “Vent” port of the switch body. When the pressure acting on the piston becomes large enough to overcome the spring force, the spool shifts and the center o-ring moves in between the vent grooves on the bottom sleeve. Instrument pressure at the “In” port “Bleeds” into the reservoir through the “Vent” port.The pressure switch “Bleed” action is the same for Model 4HL2. For this model of operation, the switch acts as a normally closed valve and is called a low switch. When normal sense pressure is acting on the piston, the center o-ring on the spool is above the vent grooves in the top sleeve, thus preventing the instrument pressure from passing to the “Vent” port of the switch body. When the sense pressure decreases to an abnormal level, the spring force shifts the spool and the middle o-ring on the spool becomes positioned in between the vent grooves in the top sleeve. Instrument pressure at the “In” port, “Bleeds” into the reservoir through the ‘Vent” port. Changing the sense pressure value when the switch is used as either a high or low id done by altering the force of the spring, the size of the sense piston force is accomplished by turning the spring cap to increase or decrease the spring compression. The piston diameter is changed by adding or removing o-rings on the piston or changing the piston.2.0 INSTALLATIONThe “SS-H” can be panel mounted (with optional panel mount nut) or supported by piping from the sense port in either verticalor horizontal positions. If the switch is mounted horizontally, it is recommended that the small vent holes in the side of the switch body be oriented in a downward position. This will prevent any debris from accumulating in the spring cavity or above the sense piston.Proper PIPE thread sealant should be used on any pipe fittings threaded into the pressure switch ports. If stainless steel fittings are used, a sealant that will prevent galling is required. When the switch is mounted using the ½” NPT base connectionis adequately tightened, DO NOT loosen the body from the base or re-position the ports. Instead, remove the switch and re-make the ½” NPT connection.3.0 DISASSEMBLY (See Spec Sheet)Tools and materials required for proper disassembly, repair and assembly are as follows:1. 7/8”, 1” and 1-5/16” open endwrenches or two crescent wrenchesof adequate size.2. Smallpliers.3. For switches using ¼” diameterpiston, 1 ¼” open end wrench or asuitable crescent wrench.4. High quality silicone base lubricant.5. An appropriate safety solvent.3.1 PARTIALDISASSEMBLYA) SpringRemoval3.1.1 If the switch is installed in anoperating instrument system, it is notnecessary to remove any instrumentsupply or sense pressure. If the unitis a high switch, it will trip whenchanging the spring. If it is a lowswitch, it will not trip when changingthe spring. Precautions should betaken to avoid any unwantedreactions in the instrumentationsystem.3.1.2 To obtain access to the spring (Item2), rotate the lock ring (Item 4)clockwise to loosen it from the springcap (Item 1).3.1.3 Rotate the spring cap (Item 1)counterclockwise until it isdisengaged from the switch body(Item 10).3.1.4 Remove the spring from its cavity inthe switch body. If the parts tube(Item 3) is inside the spring, careshould be taken not to lose it.3.1.5 Follow the procedures in repair andassembly section (Steps 4.15 and4.16) of this manual re re-install thespring.B) PistonRemoval3.1.6 If the switch is panel mounted, it isnot necessary to remove it from thepanel. It will be necessary todisconnect any piping or tubing fromthe base that would prevent thebase from being removed. When theswitch is supported by the ½” NPTconnection on its base (Item 16),disconnect any piping or tubing fromthe switch body that would preventits removal from the switch base.CAUTION: Be sure that allinstrument or sense pressures arecompletely bled to zero beforedisconnecting any piping or tubing.3.1.7 Use the appropriate wrenches tohold and loosen the base from theswitch body. Unthread the basecompletely from the switch body.3.1.8 Use the small pliers and grip theraised ridge on top of the piston(Item 15) and pull it from the switchbase (Item 16).3.1.9 If the ¼” diameter piston (Item 19) isinstalled and must be removed fromthe large piston, use the properwrench to hold the ¼” diameterpiston and grip the large piston withthe pliers at the small diameterabove the groove for the .5” pistono-ring (Item 18). Rotate either onecounterclockwise to loosen andseparate the pistons.3.1.10 Remove the installed o-ring from thepiston.3.1.11 Procedures for re-installing thepiston o-rings are in the repair andassembly procedure of this manual.3.2 FULLDISASSEMBLYNOTE: Use the following instructions to completely disassemble the pilot for repair and cleaning. CAUTION: Be sure that all instrument or sense pressures are completely bled to zero before disconnecting any ping or tubing.3.2.1 Follow the procedures stated underpartial disassembly to remove thespring and pistons.3.2.2 Remove the spool (Item 14) from theswitch body. If it is necessary, usethe small pliers and grip the smallend of the spool. Removing thespool also removes the bottomsleeve (Item 13).3.2.3 To remove the top sleeve (Item 8),an o-ring pick (pointed prying tool)can prove useful. Just insert the pickinto one of the .041 holes in the topsleeve and pull the sleeve out. Notethat while using the pick, care shouldbe taken not to scratch the bore onthe top sleeve.3.2.4 The seals on the shaft and sleevesmay now be replaced as perinstructions given in the repair andassembly section of this manual.。

If you need to take the call back on the aux telephone, simply pick up the telephone handset before the innkeeper LTD’s <Drop> button is pressed.To use an auxiliary phone equipped with a “Hold” feature to place or screen acall, first set up the call and place the call on hold. When you are ready to take the call on Innkeeper LTD, press the <Call> button on the innkeeper LTD andyour telephone will automatically release the hold.Your phone will operate as a normal telephone anytime you are in Drop mode.Leaving the hybrid connected between the wall jack and your telephone will not affect normal use of your phone. Audio will only pass through the hybrid whenyou press the <Call> button.Optional Jumper SettingsIf the incoming Caller level is too high and peaking the red -3 dB LED, youmay need to change the setting of an internal jumper. Disconnect power fromthe hybrid and remove the cover of the innkeeper LTD to locate Jumper 1. The default position for this jumper is closed (covering both pins). Changing thejumper to the open position (either remove the jumper or cover just one pin) will provide 6 dB attenuation of the incoming audio signal.Auto-AnswerThe <Auto-Answer> feature will answer on the first ring. When <Auto- Answer> is enabled, you can still make calls manually using the <Call> button.When finished, you can either drop the call manually or allow the call toAuto-Disconnect. innkeeper LTD will look for a CPC disconnect signal from the phone company to determine when a call has disconnected. This can take up toa minute.6innkeeper LTD™Digital Hybrid7Remote ControlRemote Control Remote Control JackThe RJ-45 jack on the back of the innkeeper LTD provides connection to anoptional JK Audio Guest Module 1 remote control, or it can be wired to the switch contacts on your broadcast console.

Does the innkeeper LTD send a burst or beep downthe phone line at the beginning of each call like ourcurrent hybrid?No. Innkeeper LTD uses the actual transmit signal to evaluate the phone lineand tune its algorithm. As you begin to speak, innkeeper LTD is hard at workcanceling your voice from the Caller Output jack. Within milliseconds yourvoice is reduced into the noise floor.2. Can I use the innkeeper LTD on a VoIP line?Many VoIP lines have an analog telephone adapter you can connectyour telephone to. If you can use any standard analog telephone, theninnkeeper LTD should work great. If you have to use a specific telephone,you should consider our AutoHybrid IP2 VoIP hybrid or Innkeeper PBX digitalhybrid instead.3. The caller’s audio is too high and is always distorted eventhough I have the Caller level control turned down low. Whatelse can I do?The Receive LED meter will indicate the level of audio coming in from thetelephone line, just after it passes through the DSP. The Caller level controlwill only set how much of that audio will be sent to the output jack, and willhave no effect on the LED meter. If your incoming audio level is unusually hotand already peaking the –3 dB LED, there is a jumper on the circuit boardyou can change to attenuate the incoming audio. Please see page 6 formore information.4. I have my new innkeeper LTD connected to the phone jack inmy office. Why does it keep dropping the calls as soon as Itry to connect it?The telephone jack in your office is very likely for a multi-line phone system.The jack may look like a standard phone jack, but it is wired differently andmay carry voltage on different pins which could cause serious damage to yourhybrid. Innkeeper LTD should only be connected to a single, analog phoneline. Check with the telephone specialist in your building for the possibility ofgetting an analog line for your innkeeper LTD.5. I have my new innkeeper LTD connected to an analogextension in my office. It will auto answer just fine but doesnot auto disconnect after the call has ended. How can I makeit auto disconnect properly?A PBX phone system can be programmed to provide an analog line. Checkwith the telephone specialist in your building for the possibility of resetting thecharacteristics of your analog line to provide an appropriate CPC disconnectsignal.10innkeeper LTD™Digital HybridManufacturer’s Name:Manufacturer’s Address:JK Audio, Inc.1311 E 6th StreetSandwich, Illinois 60548 USADeclares that the product:Product Name:Model Numbers:innkeeper LTD Digital Hybridinnkeeper LTDConforms to the following Product Specifications:Safety: ESD:Emissions:Telecom:AS/NZS 60950.1:2003CAN/CSA-C22.2 No. 60950-01-03UL Standard 60950-01 1st editionEN 55024:1998; EN 61000-3-2; EN 61000-3-3EN 55022:1998AS/NZS CISPR 22 (2002)FCC Part 15, Subpart BICES-003AS/ACIF S002:2005FCC CFR 47, Part 68TIA968 A-1, A-2, A-4The product herewith complies with the requirements of the following Directives and carries the CE marking accordingly:LVD 2006/95/EC (Safety)R&TTE 1999/5/EC (Telecom)EMC 89/336/EEC (EMC)RoHS Directive 2015/863The Technical File containing supporting documentation is maintained at:JK Audio, Inc (Corporate Headquarters)Compliance Manager1311 E 6th StreetSandwich, Illinois 60548 USA815-786-2929 phone815-786-8502 faxDeclaration of Conformity 11Declaration of ConformityDeclaration of ConformityFCC RegistrationFCC RegistrationYour new JK Audio product has been registered with the Federal CommunicationsCommission (FCC).

DP-502 User’s GuideThis DP-502 (the ‘device’) based system allows multiple devices to connect to a server and automatically update audio contents on a daily basis. The device is loaded with up to 13 sound files (1 ‘generic’ plus 12 month s) andloop-plays the generic file and the current month file alternately. Every day at a specific time the device will try to connect with the server and download updates if there’s any. If errors should occur during the connection the server will put an indication on the screen to alert the user. In addition to the scheduled connection time, the device also tries to connect upon power up. This allows updates to be downloaded and become effective immediately, although manual operation (power cycling the device) is required.Devices may be assigned to different groups (if necessary) to take advantage of group default settings. Each group has its own server (which can be shared with other groups) and set of default sound files. When a device is assigned to a group it automatically gets the group default settings, making it easy to set up. When a group default setting is changed all devices in the group automatically gets the change, making it easy to change. However, a device does not need to use all group default settings. It may have some settings changed to its own. For example, it may have a generic message different from other devices in the same group, or it may have a different connection time so that all devices do not try to connect at the same time.Device configuration data such as server IP address, connection time and set of sound files are stored on an SD card. The card is programmed on the server and then moved to the device. Afterwards, changes can be made by either swapping cards (if network connection is unavailable) or letting the device do the automatic daily update. Harware DescriptionsThere are two push buttons on the top of the unit. The Monitor button turns the internal speaker on and off, but does not affect the operation in any other ways. The other button is useless. On the back side from left to right, there is a speaker volume dial with power switch, a power jack, a 1/8” mono phone jack for audio output, a RJ-11 telephone jack (useless), a USB port (useless), an SD card slot, and a RJ-45 Ethernet connector.-The audio output is low power and not meant to drive speakers directly.-The device accepts SD and SDHC cards of up to 32GB.-Both WAV and MP3 files are supported.Software InstallationRun “DP-502 Setup.exe” on the CD to install the DP-502 software on a PC that’s to become the 24/7 server where every associated DP-502 unit will download new contents from on a daily basis.Restart Windows after software installation. From now on a server program called “DP 502 Server US” will start to run automatically upon power up, but you can always manually stop it at any time. Note that when the server program is stopped, DP-502 units will not be able to get updates from the server.This icon on the task bar indicates that the server program is up and running. You can see the currentserver status by clicking the icon. To stop running the server program, right click on this icon and select“Close window”.This icon on the desktop is a shortcut for the console program. The console program allows the user toconfigure both the server and the devices (such as IP address, connection time and sound files) , as well as program the SD card for use in the device initially.ETM 3.0A utility program called ETM 3.0 also needs to be installed by running “ETM 3.0 S etup.exe” on the CD. A shortcut will be created but this program will not run automatically upon power up. It is used to find devices connected to an LAN. This program can work within a LAN only, not over the Internet. Therefore it needs to be installed on a PC that’s on the same LAN as the target device.When ETM 3.0 is installed a program called WinPcap 4.1.2 is also installed. Do not remove WinPcap 4.1.2 otherwise ETM 3.0 will not work.Server IP Address AssignmentThe server must be assigned with a static IP address in order for the devices to find it. If all the devices are within the same LAN as the server then the server’s IP address may be a private one such as 192.168.1.100. Otherwise the server’s IP address needs to be a public one. You must obtain a public sta tic IP address from your Internet service provider at additional costs if you don’t have one available already.Device IP Address AssignmentThe device’s IP address, which does not need to be static, is automatically assigned by the LAN’s DHCP service. We must know this address in order to configure the device. There are two options to find out. The first option is to look at the router’s DHCP assignment table which unfortunately is not always available. The second option is to run ETM 3.0 as described above.Device ConfigurationIn addition to the configuration data on the SD card, the device also needs additional configurations done via thene twork. These configurations, usually done only once, are stored in the device’s internal flash memory. Only one device should be configured at a time in order to avoid confusion. If you put multiple new devices on the LAN at the same time, you may not be able to tell them apart.There are two ways to configure the device. If you know the device’s IP address already (by looking up the router’s DHCP assignment table), you may enter it into the browser (e.g. http://192.168.1.100) and get to the login window. The factory default user name is dp502 and the password is 1234.Otherwise you may run the ETM 3.0 program. You’ll get a window like the following. If no device is found, click the ReFresh button to try again.Only one device is found here. Select/highlight the target device (if more than one device are listed) and click the Config button. When the login window appears, enter dp502 for the user name and 1234 for the password.If you want to be able to identify a device with ETM 3.0 later, label it with the MAC address since every device has a different MAC address.If the lo gin is successful, you’ll get a screen like the following:User Name & PasswordYou may change them if you like.DHCP ClientBetter keep it enabled unless you know what you are doing.Internet ServiceBetter keep it unchanged unless you know what you are doing.Sync Time with PCPress the button if you want to sync the device’s internal clock with the connected PC (not necessarily the server). If you are configuring the device for a different time zone then this will do no good.NTP (Network Time Protocol)There are many NTP servers on the Internet that broadcast current date and time information. It’s better to enable NTP server so that the device can get the information and always keep its clock accurate. You may select any NTP se rver on the list (it doesn’t really matter) or define your own.Time ZoneSelect the time zone that the device will be working in. Note that Daylight Saving Time is not adjusted automatically so someone has to manually do it by shifting the time zone up and down by one hour.Update SoftwareSomeday you may be able to have the device’s firmware, when necessary, updated remotely.The Group WindowThe Group Window, which opens right after the console program is executed, looks like this:In this example, two groups (Group A, Group B) and one device (Device A1) have been set up.-To add a new group: right click anywhere in the left pane, select Add Group.-To rename/delete a group: select/highlight the group, right click, select Rename/Delete Group.-To add a new device under a group: select/highlight the group, right click, select Add Device.-To rename/delete a device: select/highlight the device, right click, select Rename/Delete Group.The configuration data shown in the window is for Group A which is the selected (highlighted) item. Any changes to the configuration data will be automatically applied to all devices belong to that group, with some exceptions that will be explained in the Device Window section.The Save To SD button is grayed out because it does not apply to group configuration.The Server IP and the Server Port are both grayed out, but they can be changed by right click anywhere in the left pane and select Set Server IP and Port.A correct password is required for the device to get updates from the server. When the password is changed here the server would still remember the old one, so that devices with the old password can get through when they try to connect for the first time after the password has been changed.If there are many devices to be served by the same server, it is better to stagger the Connect Time in order to avoid network congestion.For loading sound files you may either enter their paths directly, or click the […] button to open a n avigation window.The Device WindowThe Device Window, which opens when a device is selected, looks like this:In this example, the Use Default box has been unchecked for Connect Time and Generic, and both items have a different value than the group default. This is how a device configuration item can be set different from the group default. If the Use Default box is checked again, the item will automatically be restored to the group default.After the device configuration has been set up properly, attach an SD card (via a card reader) to the PC and click the Save To SD button on the upper right corner. After the SD card is written, remove it from the PC and insert it into the device. The device is now ready to work!。
