PROGRAMMING
Set Relay Set Up to "Rake Control" (P100=5) to preset relays as follows.
PARAMETER RL#1 RL#2 RL#3 RL#4 RL#5
P110 Relay Allocation 31231
P111 Relay Function 50 1 1 1 49
P112 Relay A Setpoint 80% 90% 10% 90% ----
P113 Relay B Setpoint 20% 85% 15% 85% ----
OPERATION
By level (as indicated by the Point Number bar graphs)...
1. The rake control:
a) is turned "on" when Point # 3 = 80%.
b) is turned "off" when Point # 3 = 20%.
2. Alarms indicate critical operating conditions.
a) Hi Alarm (Point 1) = high channel inflow (on 90%, off 85%).
b) Lo Alarm (Point 2) = low channel outflow (on 10%, off 15%).
c) Hi Alarm (Point 3) = rake malfunction (on 90%, off 85%).
d) All Alarms = HYDRO+ power interruption.
3. The 4-20 mA output is proportional to level on Point 1. If desired, set the mA
Allocation for Point 2 (P202 = 2) or for differential Point 3 (P202 = 3).
