Forapplications where a Display module will not bepermanently mounted, the service technician can usean optional extension cable (WHA29A-600R) totemporarily connect a Display module to the System toverify the sensor reading and FOR SETPOINTD3503-DigitLCD DisplayModuleConnectorSetpointButtonModu leConnectorFigure 2: Display Module FeaturesOperationThe Display Modules receive their power, sensor, andsetpoint information from a System 350 controlmodule.

3 A 3-digit LCD (Liquid Crystal Display ) providescontinuous readout of the sensor view the setpoint reading, press the PRESS FORSETPOINT button located on the face of the button must be pressed and held forapproximately three :The D350, D351, and D352 Display Modules are matched tothe A350, W351, and P352controls, respectively. If anincorrect Display module is usedon a System , the Display providesinaccurate readings. See Table 2for more information on choosingthe correct D350 Display !WARNING:Risk of Electrical power supply beforemaking electrical connections toavoid possible electrical shock orequipment Display Modules are housed in a compact NEMA 1plastic enclosure designed for standard 35 mm DIN railmounting. The Modules are not position sensitive, butthey should be mounted for convenient wiring andadjustment. Four key-slot mounting holes on the backof the control case are provided for surface mountingwhen Display Modules plug into the control and otherSystem 350 add-on Modules via 5-pin connectorslocated on either side of each 350 Modules can be arranged in any order;external wiring is not required to interconnectcomponents.

After necessary adjustments andelectrical connections have been made, put the systeminto operation and observe at least three completeoperating cycles before leaving the troubleshooting the Display module, verify thatthe System control is functioning properly.

5 Consult theappropriate System 350 bulletin for operatingspecifications and troubleshooting the control is functioning properly, use the followingprocedure to troubleshoot the Display Measure the temperature, pressure, or humiditywith an instrument that is at least as accurate asthe sensor in the System , and compare this withthe readout on the Display If these values do not match within areasonable range (for example, ), checkthe sensor for proper wiring and to the appropriate sensor bulletin forinformation on sensor If the sensor is wired and operating correctlyand the Display reading is incorrect, the displaymodule must be Press the PRESS FOR SETPOINT button on thefront of the Display module. If the value displayedon the LCD is out of range, replace the displaymodule. Refer to Table 1 for out-of-range valuesfor the various Display If pressing the PRESS FOR SETPOINT buttonresults in a reading other than the expectedsetpoint value, check the setpoint dial setting andcorrect if necessary.
