Series BDPA Adjustable Differential Pressure AlarmSpecifications - Installation and Operating InstructionsBulletin E-80-BDPAThe Series BDPA Adjustable Differential Pressure Alarm with built-in audible and visual indication is designed for overpressure, vacuum, and differential pressure applications. The scaled adjustment knob allows changes to the switching pressure to be made without a pressure gage. The BDPA is available with settings from 0.08 in w.c. (20 Pa) to 20 in w.c. (5000 Pa). The silicone diaphragm and PA 6.6 body make the Series BDPA perfect for use with air and other noncombustible gases. The Series BDPA can be used in monitoring air filters and ventilators.Use only with mediums such as air, or other noncombustible or non-aggressive gases. Otherwise operating faults or accidents may occur.Alarm FunctionWhen system pressure reaches alarm point on knob, LED will flash once every 30 seconds while alarm buzzer will sound every 60 seconds. This indication will continue until alarm condition is corrected or snooze button is pressed. If snooze button is pressed the audible alarm and LED indication will cease for a three day period. If after three days the alarm condition persists, the alarm buzzer and LED indication will restart to notify the alarm condition is still present.Mounting AlarmFirst check the pressure alarm to ascertain whether any damage is visible on the housing. If the housing is leaky because of damage, the pressure switch must not be used.Switching pressure specifications apply to vertical installation which is also the recommended position with pressure connections pointing downwards.Only if there is no potential for condensate forming can you mount the pressure switch horizontally. In this case, however, the switching values are approximately 0.08 in w.c. (20 Pa) higher as indicated on the scale. In the horizontal position, the pressure switch should be mounted ‘lying down’ only (that is to say with the electrical connections pointing upwards). Do not mount the pressure switch in a hanging position (that is to say, not ‘overhead’ with the electrical connections pointing downwards). Otherwise the device will function inaccurately.a) Mounting with Screws or Brackets1. To mount the pressure switch, L-shaped A-288 and S-shaped A-289 mounting brackets can be ordered separately. To secure the device on the rear side of the housing, only use the sheet metal screws (3.5 x 8 mm) which are supplied together with the mounting brackets. Under no circumstances must you use longer screws. Otherwise, the base of the housing could be punctured resulting in the pressure switch leaking.2. You can also mount the pressure switch directly on a wall. To do this use screws with a maximum diameter of 0.315˝ (8.0 mm), if you use the outer mounting lugs to screw the device in place. Do not tighten the screws so much that the base of the device is deformed. Otherwise, the pressure switch can be shifted out of position, or leak.Installing HosesImportant: Pressure tubing cannot be kinked. Pay particular attention to this point if you run hoses over an edge. It is better to form a loop. If the hoses are kinked, the device cannot function accurately.a) For connection to the pressure switch two fittings inherent in the housing are provided for hoses with an internal diameter of 1/4˝ (6.0 mm).1. Connect a hose with the higher pressure to socket P1 which is located on the lower section of the housing.2. Connect a hose with the lower pressure to socket P2 which is located on the middle section of the housing.After you have installed the hoses, it is absolutely essential to check them for tightness of fit at the connection points, and to make sure that they run without any kinks. Electrical ConnectionWork on electrical installations must only be carried out by electricians who are specifically trained for this purpose.1. If using a 0.275˝ (7 mm) connecting cable, you can line up the press nut, the plain washer and the sealing ring directly on the cable.2. If using a 0.393˝ (10 mm) connecting cable, you must first break the inner rubber ring out of the sealing ring directly on the cable. Then line up the press nut, theplain washer and the sealing ring on the cable.First make sure that there is no voltage on the connecting cable while you are working on the electrical connections. Otherwise, apossible electric shock may result and the connected equipment may be damaged. For cable gland models, the seal in the screw cable connection is designed for cables with alternative sheath diameters of 0.275˝ (7 mm) or 0.393˝ (10 mm). Only use these sizes – otherwise the screw cable connection cannot seal adequately.[7.5]Ø11/64[Ø4.5][P2] -+ [P1]outputinputTest/buttonPrinted in U.S.A. 9/20FR# 443824-00 Rev.4©Copyright 2020 Dwyer Instruments, Inc.Setting the Pressure RangeMake absolutely certain that there is no voltage on the electrical connections before you carry out any setting on the pressure switch. Otherwise, it could be fatal if you accidentally touch the electrical connections or the metal adjusting screw while you are performing the settings.a) Use the adjustment dial to set the pressure which should trip the alarm on during an increase of pressure.1. The indications on the dial are only correct for the vertical mounting position.2. When the pressure falls, the alarm returns to its resting position as soon as the pressure falls below the dead band.Attaching Covera) Insert the screw cable connection into the recess provided for this purpose on the housing.b) Then place the housing cover in position and screw it down evenly on to the pressure switch.Testing the SettingDo not operate the system until the housing is closed. Otherwise there is the possibility of a electric shock if you accidentally touch live parts. Check the trip and reset pressures by slowly increasing the pressure and then allowing it to fall again. To test that audible alarm and LED light are functioning properly without connected pressure, press the snooze button. The alarm buzzer and LED will activate for 1 second.Important: Observe the maximum permissible operating pressure of 40 in w.c. (10 kPa) which is indicated in the data sheet. Otherwise the pressure alarm may be damaged.MAINTENANCEUpon final installation of the Series BDPA Adjustable Differential Pressure Alarm, no routine maintenance is required other than possible battery replacement if used. Roughly one week before the battery goes dead, the LED will pulse 3 times once every minute while every fifth minute the alarm buzzer will synchronize with the LED giving off 3 short signals notifying of a low battery. A periodic check of system calibration is recommended. The Series BDPA is not field serviceable and should be returned if repair is needed (field repair should not be attempted and may void warranty). Be sure to include a brief description of the problem plus any relevant application notes.

派克SSD590调速器报警及故障处理当调速器出现跳闸时，显示屏会立即出现一条信息，说明跳闸原因，可能出现的跳闸消息如报警信息：当跳闸发生时，MMI上将出现一个报警信息，“报警状态”（ALARM STATUS）菜单中同时显示跳闸信息。

“正常存储”（HEALTH STORE）和“正常字”（HEALTH WORD）显示十六进制值的参数信息，或者当出现一个以上的报警时显示十六进值的总和。

这样，单一的值可能代表着一个报警或多个报警。

注：十六进制指的是在计数时以16为基数而不是以10为基数的通常算法。

所使用的16上“数字“是从0—9 A—F，因此，一个8位字节由00 到FF范围内的两个字符来表示，而一个16位字则由0000到FFFF范围内的四个字符来表示。

最后报警（LAST ALARM）“最后报警”所显示的是已经显示过的最后报警信息。

要将这一参数复位，只需简单的按一下向下按钮就可以清除报警。

也可以将辅助电源开关关闭后再开启，显示示“无有效的报警”（NO ACTIVE ALARMS）.正常字（HEALTH WORD）这一参数用来持续监控调速器的状态，当添加或清除报警时，显屏将立即更新，显示这些报警的十六进制总和。

当“启动”C3 输入为高电平，且当没有跳闸条件存在时，其值回复到0X0000正常存储（HEALTH STORE）它显示的是引起跳闸的第一次报警的十六进制值。

当“启动”C3 输入为高电平，且当没有跳闸条件存在时，其值回复到0X0000 。

当一个以上的跳闸同时显示时，跳闸字便只相加在一起形成显示值。

在每个数字内，10-15之间的值用A到F字母显示。

例如，当“正常字”参数为01A8时，它代表第三位为1，在第二位为8和2，（8+2=10，显示为A）,第一位为8.反过来，它代表处于活动状态的跳闸“励磁故障”（FIELD FAILED）、“编码器故障”（ENCODER FAILED）、“过电压”（OVER VOLTS）和“散热器跳闸”（HEATSINK TRIP）.对于调速器不能解决的报警，我们可以通过禁止报警的方式，把某个无关紧要的报警屏蔽。
