GENERAL ALARMS
If relay operated controls are not required, the following general alarms may be added
to the general application programming.
Alarms (similar to controls) are always based on level regardless of the Operation
(P001) selected.
RELAY INTERCONNECTION
The relay contact illustrations adjacent to the HYDRO+ relay terminals are shown in
the power off, de-energized, alarm on, control off condition.
Connect the HYDRO+ relays as follows:
RL1 to Hi Alarm (energized = alarm off, de-energized = alarm on)
RL2 to Lo Alarm (energized = alarm off, de-energized = alarm on)
RL3 to Hi Hi Alarm (energized = alarm off, de-energized = alarm on)
RL4 to Lo Lo Alarm (energized = alarm off, de-energized = alarm on)
