Service Manual
Alarm Screen:
If a fault occurs which requires a Manual Reset, the unit will
go into a lockout condition and the Alarm Screen will be
activated. The screen will switch between a black or red
background every 5 seconds with the text “Alarm Unit Needs
Servicing” shown on the display.
A message box shows the alarm status of the two (2) control
modules. Mod1 is for Control Module 1 and Mod2 is for
Control Module 2. A description of the alarm will be beside
the control module with the fault. If a control module does
not have a fault, “No Alarm Present” will be in the text.
It is possible for one control module to be in alarm while the
other continues to function. However, it will not be possible
to view any other screens until the control module is reset.
Reset button - The RESET button must be pressed to reset an
alarm. Once the button is pressed, the Reset Confirmation
Screen appears. You are asked if you wish to reset the control
module. If so, press the YES button. If you do not wish to reset
the control module press the NO button. If neither button is
pressed within 20 seconds, the screen will return to the Alarm
Screen.
Once the condition has been corrected and the alarm is reset, the
Status Screen will be displayed.
