Function = Limit upper/lower:
When the relays are used as upper or lower limit switches, program
the following:
Parameter: choose one of the following process values
 Oxygen
 Temperature
 Sample Flow
 Saturation
Setpoint: If the measured value rises above respectively falls below
the set-point, the relay is activated.
Parameter
Oxygen
Temperature
Sample flow
Saturation
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.
Parameter
Oxygen
Temperature
Sample flow
Saturation
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
Function = Control upwards/downwards
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.
