Operation; Inspection And Maintenance - SFA Sanipit Manual

5.3 STARTING FREQUENCY
To prevent motor overheating and excessive stress on the motor, seals
and bearings, limit the number of starts to 60 per hour.
5.4 COMMISSIONING WITH THE CONTROL BOX
5.4.1 Operations required for commissioning
1. Perform a functional and sealing test of the sewage pumping station:
Once the plumbing and electrical connections have been made, check
that the connections are watertight by letting water flow through the
inlet. Make sure that the unit is operating correctly by carrying out at
least two start cycles with water to test the system.
2. Check the points on the checklist (see 8.3 Checklist for
commissioning, inspection and maintenance).
NOTICE
Dry running of the pump.
Damage to the grinding system.
Ö Do not run the motor in forced operation (by pressing
the button on the control box) until the station is filled
with water.

6. OPERATION

6.1 EXTERNAL CONTROL BOX OPERATION
The control box provides visual (led) and audio (buzzer) informations
on the state of operation of Sanipit. It also has a forced activation but-
ton for the pump.
Front of the control box :
1 Yellow LED: Main supply
2 Red LED: alarm
3 Manual activation / Alarm reset
In normal operation, the main supply LED is steady yellow to indicate
that the unit is powered.
General alarm
BUZZER LED
Yes (2) steady red
Yes (2) flashing red
Yes (2) steady red
Yes (1) and (2) off
General alarm reset
If the problem that triggered an alarm above disappears, the buzzer
stops, but the red alarm LED remains on.
The reset button (3) will stop the buzzer in any cases, but it will only
turn off the red LED if the problem that caused the alarm has been
resolved. The alarm of the remote alarm system also remains active
until the problem has been solved. This prevents the system from being
«abandoned» in default.
Forced activation button
NOTICE
Dry running of the pump.
Damage to the grinding system.
Ö Do not run the motor in forced operation (by pressing
the button on the control box) until the station is filled
with water.
Pressing the forced activation button will start the pump immediately,
even if the level sensor is not activated. A second press stops the pump.
6.2 ALARM BOX OPERATION
The wired alarm box does not require a separate power supply. The
power is supplied through the Control box. In case of power failure, the
alarm unit's battery takes over.

sponding LED on the control box.
2/ The yellow «mains» LED indicates the power supply status of the
alarm box:
- steady lit = Sanipit connected to the mains supply,
- flashing = power failure on the Sanipit.
3/ The alarm box sounds as long as the fault is present. To stop the
alarm, press the Reset button on the Control Box or the Reset button
under the alarm box.
The alarm box can be completely switched off by a long press on the
Reset button.
