WILO SE 2020-12
Function
Description
Simulate RESET key
Closing the input is equivalent to pressing the RESET key.
Simulate START A key
Closing the input is equivalent to pressing the START A key.
Simulate START B key
Closing the input is equivalent to pressing the START B button.
Automatic test inhibition
Prevents automatic test execution
LED test
Turns on all LEDs on the front panel (lamp test).
Automatic stop enabled
When closed, it enables the automatic motor stop parameter P02.16. To comply with EN 12845
this input must be deactivated.
Pump pressure switch started
When the input is activated it indicates that the pump is under pressure.
Partially open suction valve
With input activated, it signals alarm A69 Suction valve partially open.
Delivery valve partially open
With input activated, it signals alarm A70 Partially open delivery valve.
Local pump sprinkler alarm
With input activated, it signals alarm A71 Pump room sprinkler in operation.
Pilot pump (jockey) active
With input activated, it signals that the pilot pump is started.
Thermal pilot pump (jockey)
With input active, it signals that the thermal protection of the pilot pump has been activated.
Alarm A73 Jockey pump thermal alarm is generated.
Drainage pump anomaly
With active input signals that the drainage pump in the pump room is not working.
Fuel leakage alarm
With active input it signals that there is a leakage of fuel from the tank.
High speed motor
With active input it signals that the motor is in alarm for too high a speed.
Drainage pump
With active input indicates that the drainage pump is active.
OFF mode
Automatic mode override selector and motor start inhibition. If the motor is running, it is
stopped
Test valve
With active input, it signals alarm A78 Test valve open.
Modbus script inhibition
Inhibits that Modbus writes commands.

Overview of output functions
The following table shows all the functions that can be associated with OUTn program-
mable digital outputs. Each output can then be set to have normal or inverted function
(NOR or REV). Some functions require an additional numeric parameter, defined with
the index (x) specified by parameter P16.n.02. See menu M16 Programmable Outputs
for more details.
Function
Description
Disabled
Output disabled
Configurable
