Control (activation)
Basically, the following steps must be observed for activating this function:
1. Set digital input (DI-6) to “Spray pump fault” (see also chapter 5.2.1 “
Logical “high” (+24 V DC at the input)
≙
Pump OK
Logical “low” (0 V DC at the input)
≙
Pump fault
For example for motor protection
2. Set digital output (DO-6) to “Spray pump” (see also chapter 5.2.2 “
Logical “high” (+24 V DC at the output)
≙
Spray pump requirement
Logical “low” (0 V DC at the output)
≙
No requirement
3. A type of control must be selected. There are the following options (see also chapter 4.2.12
Spray pump control “internal”
If the release (requirement circuit 1, DI-1) is set and the conditions in the “Spray pump”
menu are met, the pump switches on.
