PROGRAMMING
Set Relay Set Up to "Wet Well 1" (P100=1) to preset relays as follows.
PARMETER RL#1 RL#2 RL#3 RL#4 RL#5
P111 Relay Function 52 52 1 1 0
P112 Relay A Setpoint 70% 80% 90% 10% ----
P113 Relay B Setpoint 20% 20% 85% 15% ----
For one pump, set the RL#1 or RL#2 Relay Function to "off" (P111 = 0).
For 3 or more pumps (5 max.), choose the relay(s) to be used and program P111,
P112 and P113 similar to RL# 1 and RL# 2 (but stagger the P112 setpoints).
OPERATION
By level (as indicated on bar graph) for 2 pumps...
1. Pump controls are operated as "alternate duty assist" (P111 = 52):
NORMAL OPERATION
a) Pump 1 (lead pump) starts at 70%.
b) Pump 1 stops at 20%, shift setpoints (lead) to next pump.
PEAK DEMAND OPERATION
a) Pump 1 (lead pump) starts at 70%.
b) Pump 2 (next pump) starts at 80%.
c) Pump 1 and 2 stop at 20%, shift lead to next pump.
2. Alarms indicate control/pump malfunction (or excessive/insufficient capacity).
a) HI alarm "on" at 90%, off at 85%.
b) LO alarm "on" at 10%, off at 15%.
c) Both alarms "on" = HYDRO+ power interruption.
3. Use the 4-20 mA output if desired...
a) proportional to level if Operation = "level" (P001 = 1).
b) inversely proportional to level if Operation = "space" (P001 = 2).
4. To view pump information in the RUN mode...
a) and then the pump # (to view the pump running hours total).
b) and hold the pump # (to view the number of pump starts total)
