Red LED „Failure Pump 1"
- Flash Signal
The Failure-LED flashes when the annual maintenance is
recommended after 2 months.
Deactivating of „Maintenance flash":
Set the operation switch pump 1 in position „Aus/Off", then
press the „Reset"-button. After releasing „Reset" the LED
„Alarm" lights up for approx. 1 second. Within this time set
the operation switch pump 1 in position „Auto". The flash
light of „Failure Pump 2" extinguish.
Reactivating of „Maintenance flash" (only possible by
using ServCom Service-Controller):
Reset the maintenance counter in the ServCom menu.
Subsequently set the operation switch in position „Aus/Off",
then press the „Reset"-button.
Note:
Deactivating „Maintenance flash" is possible starting from
version 1.0d of the pump control (see menu in ServCom).
„Maintenance flash" is deactivated, if „!" appears behind in
ServCom the version No;
„Maintenance flash" is activated, if „!" behind the version No.
is missing.
Red LED „Failure Pump 2"
- Flash Signal
The Failure-LED flashes when the control unit has moni-
tored several pump operation circuits longer than 2 minutes
each. Please contact your HOMA service.
Red LED „Alarm"
- Permanent Signal
The red 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 acti-
vated.
If the red LED illuminates together with the two green LEDs
the pumps are operating, 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 without an illumination of the yel-
low LED „Failure" and none or only one green LED illumi-
nates, please contact your HOMA service.
Yellow LED „Direction of rotation" (only 3-ph models)
The white LED in the front cover of three-phase controllers
indicates wether the phase sequence of the mains connec-
tion is correct. If the LED is illuminated, the phase sequence
is wrong.
Note : This function does not prevent the motor from start-
ing 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 (see 6.3.).
HOMA ServCom Controller for adjusting and monitor-
ing operation data is available as an accessory.

6.3. Check of Direction of Rotation

1 Ph-pumps do not require any check, as they always run
with the correct direction of rotation.
Put the pump vertical on the ground and lift one edge. Start
the motor. Viewed from above, the unit must jerk anti-
clockwise, as the correct direction of rotation is clockwise
(see 6.3.).
If the direction of rotation is wrong, interchange two of the
phases of the electric power supply. Using an original
HOMA control box with CEE-plug, this may be done by a
180° turning of the small round pole-socket at the plug-end
with a screwdriver.

7. Installation

If the pump is installed in a sump, the sump opening
must be covered with a tread-safe cover after installation.
The operator has to prevent damage through the flood-
ing of rooms caused by defects of the pump through the use
of appropriate measures (e.g. installation of alarm units,
backup pump or like that).
Fasten the tank to an even floor with expansion bolts.
Before installing the disposal units make sure that the all
national instrucions and the general measures for health
protection and industrial protection for the installation of dis-
posal units (DIN 1986) are observed. Furthermore please
pay attention to the hints below:
•
Install the unit in that way, that the operation and ser-
vice elements are easily accessable. Make sure that
there is enough space (approx. 50 cm) between the
horizontal inlet and any wall.
•
Mount a gate valve into the inlet pipe and the discharge
pipe to guarantee an easy service or demounting of the
unit .
•
To avoid sediment build-up in the discharge pipe, the
pipe, and the liftimg station, should be dimensioned for
a water velocity of minimum 0,7 m/s, for vertical pipes,
however, not lower than 1,0 m/s.
•
The incoming sewer could be ensues at the horizontal
inlet through a WC-direct connection with 180 or 250
mm, or a DN 100 or DN 50 effluent pipe. Vertical inlets
(DN 50 and DN 100) for service pipe lines are existing.
Cut off the blanked off the vertical or horizontal inlet
and connect a incoming sewer inlet which correspond
to the diameter of the inlet.
•
The diameter of the discharge pipe must be DN 50
(Saniboy G, Sanimaster G) and should not installed in
close arcs. The discharge pipe must conduct over the
sewer level, that means constantly rising over that
niveau and subsequently as a loop directly to the col-
lecting conduit.
After the gate valves from the Sanimaster G mount a Y-
piece for twin pump arrangement.
•
To prevent a freezing of the discharge pipe please iso-
late the complete discharge pipe up to the sewer level.
•
Saniboy G and Sanimaster G have no integrated swing
check valve. Mount a swing check valve and a gate
valve on top of the 90° elbow of the Saniboy G and
Sanimaster G behind.
•
For a trouble free operation of the pneumatic level con-
trol it is absolutly necessary that the pressure hose be-
tween tank and control box is installed without loops,
bending and constantly rising.
•
Cut off the blanked off end of the air vent and connect a
DN 70 vent pipe to the tank by means of the flexible
connection supplied. The vent pipe should be led out
into the open air in accordance with local regulations.
•
Mount the supplied pump controller flood protected on
the wall in accordance with local regulations.
