and screw them to the pumps. The remaining parts of the
pressure pipe can now be assembled:
1. Swing-type check valves (accessory),
2. Stop valves (accessory)
3. "Y" piece (accessory).
4. Connect up the pressure pipe with the flexible connector and
a flanged spigot (accessory) and take it in a loop over the local
backup level.
Emergency pump connection (DN 50 at front)
This connection is used for the HMP hand diaphragm pump
(accessory).
Using a (Ø 38) hole saw, open up either the right-hand or left-
hand pipe socket at the location marked and deburr the edges.
Fix the hand diaphragm pump to the wall at an easily acces-
sible place and connect it to the pipe sockets on the tank with
PVC piping and flexible connectors. Here, too, the pressure
pipe must be looped over the local backup level.
Mounting the control unit
NOTICE! Only qualified electricians may carry out electrical
works to the pump or the control units.
NOTICE! Never put the mains plug and free lead ends in water! If
water gets into the plug, this can cause malfunctions and dam-
age.
Only operate the control unit in dry rooms and keep the hous-
ing closed at all times. The control unit must be easily acces-
sible to enable it to be checked at any time. High humidity and
condensation can destroy the controls!
For the mains electrical connection of Compli 1525, 1535, 2525
and 2535 type units, a correctly installed five pole CEE power
socket is required (3/N/PEx400 V, 50 Hz). This must be located
in a dry room.
For the other types, the mains power supply is connected di-
rectly to the terminals of the main switch for the control unit.
The cross section of the connection cable must be configured
to take into account the current input of the pumps and the
length of the connection cable.
NOTICE! Only time delay fuses or automatic fuses with C char-
acteristics are to be used as pre-fuses for the pump. If the pre-
fuses have been triggered, the cause of the malfunction must
be eliminated before switching the pump on again.
Connecting the pumps
The pumps are connected to the control unit on site in ac-
cordance with the circuit diagram (appendix). The three-phase
pumps are protected with an overcurrent release or motor
protection switch, set to the rated current + 10%.
Coil thermostats
NOTICE! In addition to the overcurrent release or motor pro-
tection switch, the thermostats in the motor winding must be
connected to the control unit (terminal 30/32).
The thermostat contacts are suitable for a maximum of 250 V
/ 1.2 A (cos phi = 0.6) and are labelled 30 and 32 for connection
purposes. The motor is switched off via the 230V control cir-
cuit when the response temperature is reached. The pump is
switched on again automatically after the winding has cooled
down.
Connecting the level sensor
The level sensor is connected to the control unit on site in ac-
cordance with the circuit diagram (appendix).
The switch-on and switch-off points are set ex works for the
standard inlet height of the respective system. In exceptional
cases, however, they can be changed under the menu item
"Level control".
Alarm relays
As alarm outputs, a potential-loaded alarm relay (protected by
internal control fuse F2) and a potential-free changeover con-
tact are available.
External 230V~ flashing light or warning light (accessory)
Non-isolated alarm relay (230 V AC, fused with 2A slow-blow),
terminals N/X2 (NO contact) or N/X3 (NC contact) The relay ma-
kes contact if there is a fault (operating current principle).
If a warning light (with bulb) is shown in the system menu, set
the parameter "flashing alarm?" to "yes."
If a flashing light (with discharge bulb) is shown in the system
menu, set the parameter "flashing alarm?" to "no."
Connecting a remote fault reporting system
• Potential-free centralised alarm relay
The changeover contact (40-41-42) can be loaded with
max. 5A/250V AC. The relay drops out with error and power
failure (quiescent current principle).
• Potential-free high water relay
The changeover contact (50-51-52) can be loaded with max.
5A/250V AC. The relay makes contact if there is a fault
(operating current principle).
Battery pack for alarm system
The control unit can be fitted with a 9V NI-MH rechargeable
battery. In 9 V battery operation, the alarm only works with a
digital high water level sensor on terminals 27/28. At the same
time the jumper "BRX" must be set if the buzzer is to sound.
CAUTION!
Use only the manufacturer' s 9V NiMh rechargeable batteries!
There is a risk of explosion if dry-cell batteries or lithium bat-
teries are used!
NOTE! Check the function of the rechargeable battery at re-
gular intervals! The service life is about 5-10 years. Note the
insertion date on the battery, and after five years the battery
should be replaced as a precautionary measure.
Test run and functional check
NOTICE! First of all tighten all clamps and flanged connections.
1. Open the maintenance cover on the tank.
2. Connect the lifting station to the power supply.
3. Open the sluice valves in the inlet pipe and pressure pipe.
4. Fill the tank up to the switch-on level.
5. The pump will now switch on and empty the tank. Observe
the pumping process through the maintenance opening.
6. Lift the float of the level controller slowly by hand until it is
above the switch-on point and hold it there until the alarm
is triggered
7. Then close the maintenance opening with the cover and
seal.
8. Check to ensure that the tank, fittings and pipes are water-
tight, by carrying out several switching runs.
