7.3.3. Alarms
The PLC can intervent during separator working giving, in display, some alarm messages:

RPM OK - SEPARATOR IS READY TO PRODUCT
This is only a warning message and informs you that the separator has reached the nominal
speed and now can be fed with product (default 6.400 r.p.m.).
Help : Product pump can be started and start cycle. Push alarms reset.

LOW SPEED PREALARM ON
This is only a warning message to make you know that bowl speed is descended to a value
lower than the nominal one (default 6.000 r.p.m.). This usually happens during total
discharge.

LOW SPEED ALARM ON
This message informs you that bowl speed is descended to an unacceptable value (default
5.800 r.p.m.) and some trouble is present. When the bowl reach this low speed the feeding
pump is automatically stopped.
Help : Wait till bowl reaches nominal speed.

EMERGENCY ALARM - PUSH BUTTON ON<SB0>
This message informs you that the emergency button has been pushed and this caused the
cutting of electrical feeding to separator motor and the activation of the brake (if
automatic).
Help : Turn the mushroom head button anticlockwise and push alarms reset.

WATER ALARM - LOW PRESSURE <SP1>
This is only a warning message to make you know that water line feeding is wrong. It’s
necessary to check the right working of surge tank unit (surge tank pump, pump pressure
switch, filter, pressure reducer) and that no leakages are present. Check also the right
working of pressure switch and the minimum pressure limit that must be set to 1,0

1,2
bar, not more.
Help : Check: 1) water pressure, 2) surge tank operation, 3) clean filter cartridge, 4) push
alarms reset button.

SEPARATOR MOTOR ALARM - CURRENT OVERLOAD <QM1>
This message informs you that the separator motor has been surcharged and thermal
protection has cut the electrical feeding to the motor. Check electrical connection and
current absorption.
Help : Check: 1) lever QF1, 2) motor absorption, 3) thermistor circuit continuity QM1, 4)
push alarms reset button and start motor M1.

PUMP MOTOR ALARM - CURRENT OVERLOAD <QM5>
This message informs you that the feeding pump motor has been surcharged and thermal
protection has cut the electrical feeding to the motor. Check electrical connection and
current absorption.
Help : Open electrical box and restore thermal protection QM5 by suitable lever. Push
alarms reset button and start pump motor.

SURGE TANK MOTOR ALARM - CURRENT OVERLOAD <QM4>
This message informs you that the surge tank pump motor has been surcharged and
thermal protection has cut the electrical feeding to the motor. Check electrical connection
and current absorption.
