Operation with Advanced Microprocessor with Graphics Control

3.8.1Show Inputs

With the unit on and the fan running, the input state for the following devices may be displayed:

Air Sail Switch: normally off unless Loss of Air Alarm is active

Custom Alarm #1: normally off unless this alarm is active

Custom Alarm #2: normally off unless this alarm is active

Custom Alarm #3: normally off unless this alarm is active

Custom Alarm #4: normally off unless this alarm is active

Humidifier Problem: normally on unless this alarm is active

Filter Clog Switch: normally off unless Change Filters Alarm is active

Main Fan Overload: normally on unless Main Fan Overload Alarm is active

Shutdown Device: normally on unless unit is off through the Fire Stat or Remote Shutdown Device

Low Pressure Switch: normally on if compressor circuit 1 is in operation

Compressor Overload: normally on unless Compressor 1 Overload Alarm is active

High Head: normally off unless High Head Pressure alarm is active

3.8.2Test Outputs

When this feature is selected, the unit is effectively turned off. When stepping from one load to the next the previous load, if on, is turned off automatically. The loads can also be toggled on/off by select- ing “ENTER.” Once turned on, the output will remain on for 5 minutes unless toggled off or the test outputs function is exited by selecting “MENU/ESC” (Compressor is limited to 15 seconds on to pre- vent damage.) DO NOT leave the unit in the test outputs mode any longer than is necessary for trou- bleshooting. The outputs are as follows:

Main Fan: main fan contactor

Compressor: compressor contactor

LLSV: liquid line solenoid valve

HGBP/CUV: hot gas bypass or compressor unloader valve (on certain units)

Part Coil: Part Coil Solenoid Valve

CWV/CGV: chilled water or GLYCOOL valve

R5 Relay: Relay 5 (heat rejection)

Reheat 1: Reheat 1 contactor or SCR Reheats (also energizes fan for safety)

Reheat 2: Reheat 2 contactor (also energizes fan for safety)

HWR: hot water solenoid valve

Humidifier: humidifier contactor (also energizes humidifier makeup valve and fan for safety)

HMV: humidifier makeup valve

Common alarm: common alarm relay

! CAUTION

Do not test a compressor output for more than a few seconds.

Compressor damage could result!

3.8.3Test Control Board

By selecting this function, the microcontroller will perform a self test lasting approximately 10 sec- onds. At the end of the test, the ROM checksum, ROM part number and version number will be dis- played.
