Weight: 975 g (2.15 lb.) unit and carrying pouch2.2 kg (5 lb.) shipping weight (unit with accessories)Product LifeExpectancy: 10 yearsCertifications:Coiled Cord3.Operation3.1StartupTo power-up the HY-ALERTA™ 500, press and hold the ON/OFF button until the Controller LCD display indicates an operational message.Warning: Only power-up the instrument in a hydrogen-free environment.After power is on, the instrument takes about ten minutes to warm-up. During this time the LCD displays a countdown to completion and the Probe Tip LED is amber. The following operations occur:The Wide Range Sensor® reaches operating temperature.A system self-test is run.Upon successful completion of the above tasks the instrument zeroes itself and automatically switches to normal operation. If an error is detected theinstrument will display an error code (see Section 10).3.2ShutdownTo power-down the HY-ALERTA™ 500, press and hold the ON/OFF button forapproximately two seconds until the Controller LCD display turns off.3.3Battery LevelAfter power-on the BATTERY LED indicates the current battery level (times areapproximate and may vary as the battery ages):Color MeaningGreen more than 60 minutes of operation remainingAmber approximately 15 to 60 minutes of operation remainingRed less than approximately 15 minutes of operation remainingA fully charged battery should last 10 to15 hours, depending on use.There is a small load on the battery when the unit is powered off. This load will discharge the battery of the unit in it’s powered off state in about 6 months.Customers that do not use the device frequently should charge the batteryand perform a bump test with hydrogen gas every one to three months tokeep the battery charged and ready for use.3.4Normal OperationDuring normal operation the instrument is detecting and reporting thehydrogen concentration near the probe tip sensor. Hydrogen readings aredisplayed on the controller LCD and the probe tip LED bar graph array. Note that due to the extreme sensitivity of the sensor, it may take several minutes to return to a near zero (less than 0.001%) reading after exposure to hydrogen. If the instrument does not return to an indication of less than 0.001% after 5minutes in a hydrogen-free environment, then invoke the Reset operation (See Section 3.6).The upper line of the Controller LCD indicates a numerical value or range for the percent hydrogen concentration or peak hydrogen value. The lower line is used to display the hydrogen meter, a logarithmic bar graph ranging from0.001% (10 ppm) to 100% hydrogen by volume. An open box on the bar indicates the last peak value obtained and filled boxes indicate the current value. The following figure describes how to interpret the hydrogen meter:The Probe Tip LED Indicator shows an increase or decrease in hydrogenconcentration. Leak detection is accomplished by watching the Probe Tip LED and the bar graph array and moving the sensor around a potential hydrogen leak.The number of yellow LEDs lit in the Probe LED bar graph array indicates detected hydrogen concentrations in four ranges as noted below:3.5Hydrogen-Free AreasFor the purposes of this document a hydrogen-free area is one with less than5ppm of hydrogen in the air.It may be difficult to find a hydrogen-free area in a facility where hydrogen is used. Nearby rooms, or even the entire building, may not be hydrogen free.To check these areas reset or zero the sensor outside, away from any hydrogen tanks, pipes, or other potential sources. Walk through the facility, watching the sensor. It is surprising how far low levels of hydrogen can spread.If the sensor is zeroed or reset in hydrogen, there will be a negative offset in the readings that could compromise the sensor’s ability to find small leaks.3.6Reset OperationThe Reset Operation is used to speed recovery from hydrogen exposure.It can be invoked from the keypad while in the top menu level (measuring hydrogen) by pressing and holding ◄►(left and right arrow buttons simultaneously) or from the Reset Menu (see Section 4). Once invoked the user is asked to confirm the operation by pressing the ENTER key. Pressing any other key will abort the operation. During Reset the LCD indicates a count down to completion and the Probe tip LED is yellow.3.7Zero OperationThe Zero Operation is used to zero the hydrogen reading if the instrument is reporting low levels (0.001% to 0.01%) of hydrogen when no hydrogen is present. This operation can be invoked from the keypad while in the top menu level (measuring hydrogen) by pressing and holding ◄ (left arrow button) or from the Reset Menu (see Section 4). Once invoked the user is asked to confirm the operation by pressing the ENTER key, pressing any other key will abort the operation.4. Keypad4.1 Numerical ChangesIn the following sections when queried to change a numeric value the ▲ (up arrow) and ▼ (down arrow) keys are used to increment/decrement the value based on the selected digit. If the ones digit is selected the value willincrement/decrement by one (9 increments to 10, 10 decrements to 9). The ◄ (left arrow) and ► (right arrow) keys are used to select another digit. Tochange a value of 0 to 100 first select the hundreds digit then press the ▲ up arrow. Pressing ◄► (the left and right arrows simultaneously) will clear any changes made and restore the previous value. Once the correct value is displayed press the ENTER key to save it. 4.2 Top Level Keypad FunctionsWhile in the hydrogen measurement screen, the keypad has these functions:Key Function ENTER Go to the Information Display menu . ▲ Display the peak hydrogen reading. ▼ Display the current hydrogen concentration. ► Clear the peak hydrogen value. ◄ Zero the sensor (see Section 3.7). ◄► Reset the sensor (see Section 3.6).4.3 General Keypad Functions (Also See Section 11)4.4 Information DisplayThe Information Display menu allows the user to view useful information about the instrument including firmware revisions, serial number, and calibration date. Enter it by can be entered by pressing and holding the ENTER button. 4.5 Firmware Rev:This displays the sensor pod and controller firmware. The left most number preceded by an ‘S’ is the Probe firmware revision. The right most number preceded by a ‘C’ is the Controller firmware revision. For example: S1.23 C2.34 for Probe firmware version 1.23 and Controller firmware version 2.34 4.6 Serial Number:This displays the product serial number.

Understanding this behavior allowsa more effective search for hydrogen leaks.The hydrogen plume from a leak generally spreads in a roughly conical shape that is easily disturbed by environmental conditions. Certain conditions such as pressure, temperature, and leak size may act together to change the shape of the hydrogen plume from a cone to a laser-like beam. This makes finding aleak more difficult.If the sensor element is near (and above) the leak, the concentration will likely be higher but the leak may be difficult to locate. As hydrogen dissipates theconcentration decreases. Generally, greater distances will increase thechance of intercepting the leak stream, but if the sensor is too far away, theresponse may be too weak to detect.When drafts or air currents are present, hydrogen will tend to be dispersed.Testing for hydrogen leaks downwind of the leak area may increase thechance of detecting the leak.If hydrogen is rising in an enclosed building the hot air near the ceiling mayslow the hydrogen’s rise. Thus, sensing hydrogen near ceiling areas with hightemperatures present may not be as effective as at a lower level.Low temperatures can also affect the behavior of hydrogen. Hydrogen stored in a liquid state is at an extremely low temperature. The low temperature ofany escaping hydrogen will be of a higher than normal density and mayinitially move downward. As the hydrogen warms, it will begin to rise upward.When checking for a leak in areas where liquid hydrogen is stored, check both above and below the area of concern.6.Bump TestA bump test is recommended every three months. The purpose of a bump testis to verify that the sensor is active, detecting hydrogen and verifying that the sensor is within the pre-set factory tolerance for accuracy. To performs a bump test perform the following:In a non-hydrogen environment, power on the instrument. Once theinstrument has gone through its standard 10 minute warm-up, use thecalibration cup that accompanies the HY-ALERTA™ Model 500, and apply 2% hydrogen to the probe sensor. Let the 2% hydrogen flow for a minimum of 3-5 minutes. After 3-5 minutes the concentration value registered on the LCDdisplay should read between 1.6% to 2.4%, which is within factory tolerance. If the 2% reading is below 1.6% or above 2.4% the instrument should go through a Verification test as outlined below.7.VerificationVerification is performed in a non-hydrogen environment to confirm that theHY-ALERTA™ Model 500 is operating properly and within the pre-set factorytolerance for calibration. The recommended verification interval is every 12months, or after a 2% bump test has been performed and the indicated values on the LCD display were outside the stated tolerance as outlined in Section 6.If the verification fails, then it should be repeated one more time.The HY-ALERTA Model 500 requires calibration only if it fails the secondverification. It cannot be field calibrated and must be returned to h2Scan for calibration service. An optional NIST traceable certificate is available uponrequest.7.1GasesVerification requires the availability of the following certified gases:2.00% hydrogen by volume in air (20,000 ppm)0.10% hydrogen by volume in air (1000 ppm)Zero grade, hydrogen-free air. Ambient air can be substituted if it ishydrogen-free.7.2Gas ConnectionGases are applied to the unit through the use of the Calibration Cup Assy. (P/N 50000009) available from H2Scan.7.3Verification KitsCustomer-specific Field Verification Kits for the HY-ALERTA™ 500 are available from H2scan.The field verification function allows the user to check the instrument’s calibration. Details on this function can be found in Table 1 on page 19. If the unit passes verification, calibration is not required at this time.If the unit fails verification, the unit should be returned to the factory for calibration.8.Battery ChargingEnsure the unit is powered OFF.Disconnect the coiled cord from the controller.Connect the battery charger to the controller.Using the appropriate A/C plug adapter for the region of use, plug the battery charger into the A/C supply.The battery charger indicator light will illuminate according to charge status as follows:Off No BatteryFlashing Green Fast chargingSteady Green Fully chargedSteady Amber StandbyFlashing Red ErrorNOTE: Complete charging may take up to 4 hours for a fully dischargedbattery.9.CleaningIf the unit becomes soiled, clean the unit with a lint-free cloth.

第一部分操作快速入门一、准备将三相四线电源线，各电机电源线，电磁阀控制线，传感器信号线，遥控手柄或上、下限位控制线（有些配料机不需上、下限位控制，则无此接线）接入端子排的相应位置。
控制柜及仪表必须可靠接地，以防止雷击和保护设备及人身安全。
二、上电控制器接入电源之前，请检查使用的电压范围，一定注意是否在交流187V～242V之间，频率为50Hz±2%范围内。
如您使用的电源不能满足这一要求，需加交流稳压电源。
操作空气开关手柄，给控制系统通电，并使系统预热30分钟。
（通电后严禁秤体进行电气焊等造成仪表及传感器易损坏的操作）三、校称设备第一次使用或长时间使用后称量不准确时，需进行校称操作，正常情况下无需校称。
PLY配料控制器只有处于“停止”状态（运行状态指示灯灭）时，才能进行校称操作。
校称前首先清空称量斗，为确保校称值的精确性，用户必须在控制器通电半小时后，再进行校称操作。
校称前，称体应稳定（无摆动）、平衡，并保证所使用的传感器受力一致。
否则应先进行称体调整。
校称时按键顺序及显示内容如下。
四、控制器配方（定值和落差）设定PLY配料控制器，最多可控制四路上料、两路卸料。
因此，如果实际只用1至3路，对不用的路数的定值，必须设定为零。
另外配料控制器只有处于“停止”状态(运行状态指示灯灭)才可以进行配方号的选择。
1 配方号的选择2 配方值的修改五、运行面板上的“启动/停止”键或遥控手柄上的“运行”按钮，便进入“配料”状态。
当各种物料上料完毕，按遥控手柄上的卸料按钮实现卸料。
卸料完成后，罐数自动加1，重新上第一种物料，开始第二个配料周期，实现全自动配料。
六、停机有罐数设定时，配料的罐数达到罐数设定值时，配料过程停止，控制器可自动停机。
在配料过程中，无论在什么情况下（有罐数控制或无罐数控制）需要停机时，可待各种物料上料完毕，按一下遥控手柄上的“运行”按钮，或控制器面板上的“停止”状态。
此时把控既可。
七、常见故障提示及处理第二部分使用说明书一、概述1 简介PLY 配料控制器是由单片微机控制，集称重、控制于一体的智能仪表。
