PROGRAMMING
GENERAL
P001 Operation = 1 (level)
P006 Empty = 1.7 m (e.g. Transducer to channel bottom)
P007 Span = 1.3 m (e.g. Channel bottom to highest head)
RELAYS
Set Relay Set Up to "off" (P100=0, preset) prior to relay programming.
PARAMETER
P111 Relay Function
P112 Relay A Setpoint
P113 Relay B Setpoint
P114 Relay C Setpoint
P115 Relay D Setpoint *

as required to satisfy individual application requirements.
OPERATION
By level (as indicated by the bar graph)...
1. The Penstock is:
a) driven more open for 0.1 minute at 45% level or less (RL1).
b) driven more closed for 0.1 minute at 55% level or more (RL2).
c) control operation is limited (P115) to every 1 minute (for stabilization).
d) both controls are held "off" if the level is between 45.01% and 54.99%.
2. Alarms indicate critical operating conditions.
a) Hi Alarm = close control malfunction (on 65%, off 60%)
b) Lo Alarm = open control malfunction (on 35%, off 40%)
c) Both Alarms = 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).
