Program List and Explanations
5.3.2.400
Hysteresis:
within the hysteresis range, the relay does not switch.
This prevents damage of relay contacts when the measured value
fluctuates around the alarm value.
5.3.2.50
Delay:
Duration, the activation of the alarm relay is retarded after
the measuring value has risen above/fallen below the programmed
alarm.
Range. 0–600 Sec
The relays may be used to drive control units such as solenoid
valves, membrane dosing pumps or motor valves. When driving a
motor valve both relays are needed, relay 1 to open and relay 2 to
close the valve.
