tank. To stop the pump release the switch. The switch
turns into the position „Aus/Off“.
Position „Off/Reset“
The pump is stopped.
Position „Auto“
Pump operation according to the liquid level in the tank.
Switch „Reset“
This switch is used to quit a failure before re-starting the
unit.
Acoustic alarm switch
Position „On“
The built-in acoustic alarm is activated. Together with the
red LEDs “Alarm“and “Failure“ the built-in acoustic alarm
will start if the level of the medium is above the alarm
level. The alarm is automatically reset when the liquid
level has been lowered below the alarm level.
Position „Off“
The built-in acoustic alarm is not activated.
The controller front cover features Light-Emitting Diodes
(LEDs) for indication of operating conditions :
Yellow LED „Incorrect phase sequence“ (only 3-ph
models)
The yellow LED in the front cover of three-phase
controllers indicates wether the phase sequence of the
mains connection is correct. If the LED is illuminated, the
phase sequence is wrong.
Note : This function does not prevent the motor from
starting and rotating in the wrong direction because it
does not measure the phase sequence to the motor.
Therefore, the direction of rotation of three-phase pumps
must always be checked if the cable between pump and
controller has been removed.
Green LED „Operation“
The green LED illuminates when the pump is operating.
Red LED „Alarm“ and „Failure“
- Permanent Signal
The red Alarm-LED illuminates in case of to high liquid
level in tank. Together with the red LED, the built-in
acoustic alarm is activated if the switch in the front cover
is in position „On“. Furthermore, the external fault signal
device, if fitted, is activated.
If the red Alarm-LED illuminates together with the green
LED, the pump operates, but the liquid level in the tank is
above the alarm level. The alarm is automatically reset
when the liquid level has been lowered below the alarm
level.
If the red LED illuminates together with the LED „Failure“,
the pump was stopped by thermal cutout. In this case,
push the „Reset“ switch. If the pump still does not work,
please contact your HOMA service.

- Flash Signal
The Failure-LED flashes when the annual maintenance is
recommended after 2 months.
