The
stop delay
is the time from the stop signal is given until the
pump is stopped.
It must be ensured that the pump is not running dry.

Switch 8 has no function in connection with the actual
application
(3 levels (4 electrodes), page 98)
, but this
setting
must
be maintained!
This setting ensures automatic resetting of alarm
signals to external alarm devices and the built-in
buzzer. However, an alarm signal will only be reset if
the cause of the fault no longer exists.
At this setting, the alarm signal must be reset manually
by means of the reset button (the reset button is
described in section
).
This setting enables automatic restarting after the motor
thermal switch has cut out the pump. Restarting will not
be carried out until the motor has cooled to normal tem-
perature.
When the pump connected is used in an explosion
hazard area, switch 10
must not
be in this position!
At this setting, the pump must be restarted manually after
the motor thermal switch has cut out the pump. To restart
the pump, push the ON-OFF-AUTO selector switch into
position OFF for a short period (the ON-OFF-AUTO
selector switch is described in section
When the pump connected is used in an explosion
hazard area, switch 10
must
be in this position!

Description
1
Green indicator light, indicating starting delay (flashing)
and pump operation (permanently on).
2
Red indicator light, indicating pump fault.
Flashing: Fault in PTC resistor/thermal switch
On: Fault in motor-protective circuit breaker.
3
Red indicator light, indicating wrong phase sequence
(only certain variants and three-phase pumps only).
4
Red indicator light, indicating common alarm.
5
ON-OFF-AUTO selector switch, three positions, see
section
7
Reset button, push-button for manual resetting of alarm
signals to
external
alarm devices and the built-in buzzer
(only certain variants), see section
.
8
Orange indicator light, which is activated by the
electrode for stop of pump.
9
Orange indicator light, which is activated by the
electrode for start of pump.
10
and
11
2 orange indicator lights, which are activated by the
electrode for high-level alarm.
In case of high-level alarm, the top indicator light is
flashing and the other indicator light is permanently on.
12
Green indicator light, indicating that the electricity
supply has been switched on.
