Leds 6,7 show the status of the electrical contact of the pressure switch. If turned on, the contact is closed, and the pump
running. In the case of an LED is off, check the functionality of the pressure switch
Shut-off
The pump keeps running even if the pressure and the status of the pressure switch are restored. The pump must be stopped
manually as required by the firefighting standard.
To stop it, set the key-operated selector switch to the "MAN" position or the Disabled position "0".
The modified version for fire-hydrant networks features automatic pump shut-off after the pressure has been restored for the
length of time specified by local regulations (the default setting is 20 minutes).
The signalling and control keypanel does not affect the automatic starting of the motor.
If the motor fails to start automatically the following information is displayed:
1 - POWER LINE ON, green LED On
3 - PUMP ON DEMAND, yellow LED On
5 - START FAILURE, yellow LED On
6 - PRESSURE SWITCH P1, yellow LED On if pressure is below of the value of start.
7 - PRESSURE SWITCH P2, yellow LED On if pressure is below of the value of start.
