PGD DISPLAY

Turning the unit On/Off : Pressing the “ ESC” & the “ Enter / Return” arrow buttons together turns on and off the unit at the display. Pressing the up arrow button followed by the “ Enter / Return” arrow button also turns unit on/off. Follow on screen instruction.

Alarm button: By pressing this button you can display the alarm that has occurred & reset it manually. When the red led indicator lights up, at least one alarm condition has occurred. If there are multiple alarms then using the arrow “ up ” & “ down ” buttons lets you scroll through them.

Up arrow button: Displays the program windows and allows the user to set the value of the control parameter

Down arrow button: Displays the program windows and allows the user to set the value of the control parameter. In default menu, pressing down arrow button displays unit operating mode.

Enter / Return arrow button: Confirms the set data. Escape button: By pressing this button, you go back one level from where you are.

Program button: By pressing this button, you get a range of sub-menu’s.

Notes

1. Strategy 1 - Gives a user selectable 0-10V value to have a fixed speed for the EC Fan. Strategy 2 - Fan speed varies tracking temperature setpoint with user selectable start and stop points. Strategy 3 - Fan speed varies tracking a pressure setpoint with user selectable start and stop points. If pressure read is outside the pressure setpoint plus differential for the set Time Delay the voltage to the fan is increased or decreased by the set Voltage Step. The controller will then check pressure for the set Time Delay and repeat process if necessary. Strategy 4 – Fan speed can be controlled from a BMS within user selectable limits. Strategy 5 – Fan speed varies to maintain a constant airflow.

ALARMS SECTION Notes : 1. Please note that the ALARMS generated will depend on the unit type & configuration. 2. All alarms can be set as Serious or Non-Serious in the user section of the controller. All serious alarms will shut down the unit 3. A05 & A09 are deemed Serious alarms by default. A05 can be changed by the user. 4. A06 is deemed non serious by default to keep a slave module of a duplex unit running in the event of a master air flow alarm. This is only when A05 is set as a non serious alarm. 5. A35 & A08 will always disable the Humidifier whether set as Serious or Non-Serious. 6. A36, if set in unit configuration as glycol will stop compressors and close all water valves. If set as dual cooling will close water valves and leave compressors running. 7. A39 indicates a fault detected in the controllers permanent memory during start up. Should this alarm occur please refer to factory for further support. 7. There may also be some additional alarms which are order specific.
