Vibration 2 -delay
After this time has expired,
the product feed valve is
closed and an alarm is trig-
gered.
– Filling water valve V2 is
opened and safety water is
fed into the bowl.
– Pneumatic brake is acti-
vated (option).
– The separator motor is
switched off immediately.
Time delay for the vibration 2 alarm which is
triggered in the case of a continuous signal on the
vibration measuring device.

SMS low pressure
delay
After this time has expired,
the product feed valve is
closed and an ejection is
triggered.
The time expires when the SMS pressure has
dropped off and T21 “minimum separating time”
has elapsed. An ejection is triggered. Accumu-
lated solids in the solids space of the space has
caused the pressure drop.

T28
Ejection monitoring
The motor current or speed is
monitored within this time. An
alarm is triggered after this
time has expired.
The motor current or speed is monitored during
the ejection phase. If the motor current or speed
does not exceed the adjusted offset during this
time, an alrm is triggered.

Brake for separator The brake is actuated for this
time.
Time to brake the separator automatically after an
alarm “Vibration 2”.

WMS-Mode
Water discharge valve V6 is
closed; it opens only when the
SMS pressure transmitter PT2
is activated.
Circulation valve V5 is closed.
Time for water content monitoring during the
separating process. The separator functions as a
purifier.

T33
SMS-Mode
Water discharge valve V6 is
closed.
Circulation valve V5 is closed.
Time for solids space monitoring. Only the SMS
sensor PT2 is activated. The solid content of the
bowl is monitored.

WMS press.check
Circulation valve V5 is closed.
Water discharge V6 is opened
and closes after this time has
expired.
Time to flush the WMS sensor.

T35
Water seal broken
Circulation valve V5 is open.
Water discharge valve V6 is
closed.
Alarm “no water seal” is trig-
gered.
Time in which the alarm “no water seal” triggers
when the WMS sensor oil and the SMS sensor
PT2 indicate pressure during the running time of
the timer.

T36
SMS press.check Filling water valve V2 is open.
SMS sensor PT2 is activated.
Bowl is filled with filling water pulse-wise for
checking the solids space. If the solids space is
not filled with solids, the SMS pressure switch
PT2 must output a pressure signal. If no pressure
builds up, an ejection is triggered.

SMS Waiting
Filling water valve V2 is
closed.
SMS sensor PT2 is activated.
Time interval between two filling water pulses
during solids space monitoring.

WMS sensor not active.
SMS sensor PT2 not acti-
vated.
Water discharge valve V6 is

Time to rinse the sensor line after the first pro-
gram start and to let the surplus filling water dis-
charge.

T39
Separator motor off
After this time has expired,
the separator motor is switch-
ed off.
Time delay to switch off the separator motor. The
function must be pre-selected in the program.
