Alarms
This function allows an alarm device to be connected. The alarm device can be
connected to two alarm relays (see wiring diagram) which are opened when the
threshold set in the ALARMS menu is exceeded. For details, see the third menu
item and the description in the Accessing the Alarm menu section.
When an alarm is triggered, it is signalled on the display by a blinking row that is
normally occupied by the operating mode. The menu key is used for RESET and
keys
can be used to scroll any alarm items that may have triggered for:
relay no. 1
- dP Dirty Filter - Tribo Probe Alarms If used
- dP minimum, Replace Filters if enabled in the menu
relay no. 2
- failed valve activation
The relays are normally closed, opens in case of alarms and opens to the control unit
switched off in the absence of power supply.
PP Open is indicated on the screen if the contact is not closed or the fan is not
connected to terminals 36_37 connector P13.
Remote Open is reported on the screen if the contact is not closed or the remote
control is connected to terminals 38_39 connector P13.
