P111 RELAY FUNCTION (continued)
Important! Relay A / B Setpoint values cannot be exactly equal.
values: 0 = off (relay is always de-energized) 6 = LOE alarm
1 = Level Alarm 7 = Transducer Cable Fault Alarm
2 = In Bounds Alarm 8 = Pump Efficiency
3 = Out of Bounds Alarm 9 =Time of Day
4 = Rate of Change Alarm 10 = Clock Failure
5 = Temperature Alarm
OPERATION FUNCTIONS
The following Relay Function options may be used only for specific modes
of Operation (P001).
FUNCTION DESCRIPTION SETPOINTS
Totalizer 1 contact closure per 1 x 10
y
units P640/P645
Flow Sampler 1 contact closure per X x 10
y
units P641-P645
or time duration P115
Scanner switches transducer inputs n/a
The Totalizer Function may be used if Operation is set for "OCM" (Open
Channel Monitor) or "PT" (Pumped Volume Totalizer), (P001= 6 or 7).
The Flow Sampler function may be used if OCM Operation,
(P001 = 6) is selected.
If DPD (differential level) or DPA (average level) Operation is selected,
(P001 = 4 or 5), Relay Number 5 is automatically set for the Scanner
function. See Interconnection/Transducer for Transducer
wiring details.
values: 40 = Totalizer
41 = Flow Sampler
49 = Scanner
