RESERVOIR CONTROL (Pump Up)
Typically, reservoirs are used to temporarily hold processed water. When the water
surface reaches a low level setpoint, the reservoir is pumped up.
The HYDRO+ provides reservoir control with only minimal application programming.
For the following example, we’ll assume Empty (P006) was set from the transducer
face to the reservoir bottom.
RELAY INTERCONNECTION
The relay contact illustrations adjacent to the HYDRO+ relay terminals are shown in
the power off, de-energized, alarm on, pump off condition.
Connect the HYDRO+ relays as follows:
RL1 to Pump 1 control (energized = pump on, de-energized = pump off)
RL2 to Pump 2 control (energized = pump on, de-energized = pump off)
RL3 to Hi Alarm indicator (energized = alarm off, de-energized = alarm on)
RL4 to Lo Alarm indicator (energized = alarm off, de-energized = alarm on)
