Switch: If pressure switches is used, then the user must select whether they are normally open or
normally closed switches.
Level
Input signal: Configure which of the analogue or digital inputs that is used as the level signal. That
can be either an analogue loop input or digital input from a switch. By setting the input signal to
“None” the pump controller will not use level to determine if the pump should run or not.
Loop: If a loop input is selected as the input signal the user must configure at which level the pump
must stop.
The levels returned from the sensor at 4mA and 20mA must be configured in the positioner.
There is a delay of 10 sec of the signals to secure stability.
Temperature
Input signal: Configure which of the analogue or digital inputs that is used as the temperature
signal. That can be either an analogue loop input or digital input from a switch. By setting the input
signal to “None” the pump controller will not use temperature to determine if the pump should run
or not.
Loop: If a loop input is selected as the input signal the user must configure at which temperature the
pump must stop.
The temperature returned from the sensor at 4mA and 20mA must be configured in the positioner.
There is a delay of 10 sec to secure stability.
