Description
failures occurs:
• Voltage value failure
• Phase sequence not correct
• Blown switchboard fuses
• Automatic mode switched off
• Alarms
It is detected at the opening of the pump
pressure switches or at the closing of the
pump priming tank float contact.
To switch on/off the automatic mode use the selector SA1 on Fig. 12a.
It is only possible to remove the key from the switchgear, if the automatic mode is switched
on. If the automatic mode is switched off, a flashing warning light 10 on Fig. 13 appears.
It takes place when the CALL pressure switch contacts are open, which is indicated by a
permanent light 4 on Fig. 13.
When the pressure switches contact will be closed (pressure is replaced) the indicator 4 on
Fig. 13 starts to flash. From this moment you can stop the motor only manually by pushing
the button 9 on Fig. 13.
The automatic start also takes place also when the pump's priming float contact is closed,
which is indicated by a permanent light 5 on Fig. 13. When the contact opens, the indicator
starts flashing. From this moment you can stop the motor only manually by pushing the
button 9 on Fig. 13.
Push button 6 on Fig. 13, a permanent light 7 on Fig. 13 appers.
Indicated by a permanent light 1 on Fig. 13. It is detected when the motor current is higher
than the threshold set for the entire duration of the intervention delay.
Indicated by a permanent light 2 on Fig. 13. When the motor starts, this is detected by the
value of power (kW) and by closing of the pump's pressurized-pressure switch (when it is
installed on the pump as demanded).
It is only possible to switch off the motor manually by pushing the button 9 on Fig. 13.
Warning: It is not possible to stop the motor when the call from the pressure switches is
present and automatic mode is switched on. In this case it is possible to stop the motor only
by switching off the automatic mode and pushing the button 9 on Fig. 13.
The alarms are indicated on the display by the relavant LED and by a cumulative flashing
LED 14 on Fig. 13.
To RESET it is possible to push the button
vated and the startup cycle controlled by the priming tank float is released.
Keep the button 11 on Fig. 13 pushed to check all the light.
