Non-isolated alarm relay (230 V AC, fused with 2A slow-blow),
terminals N/X2 (NO contact) or N/X3 (NC contact). The relay
makes 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).
Rechargeable battery for power failure indicator
The control unit can optionally be fitted with a 9V NiMh re-
chargeable battery. The "BRX" jumper 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
1. Open the maintenance cover of the tank.
2. Connect the unit to the power supply.
3. Open the shut-off valves in the inlet and the 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.
OPERATION
The control unit has a graphic LCD display. The data is evalu-
ated and updated at short intervals, which can sometimes look
like flickering. The backlighting is activated for a limited time
by pressing a button. The contrast can be changed in the sys-
tem settings menu item.
It is operated with a rotary knob and three membrane keys: an
acknowledgement button and manual-0-automatic buttons
for the pump(s).
The two LEDs show the operating status of the pumps:
• Continuous green light = Operational
• Green flashing - Pump in operation
• Continuous red light = Fault
• Red flashing - Fault, pump in operation
• Orange = Maintenance due
Operating modes
In addition to the automatic operating mode described above,
each pump can also be switched on and off manually using the
operating button.
The operating status of the control unit is shown in the display;
the existing operating mode is highlighted as a negative image.
MANUAL/ON
The pump continues to run in manual mode until a different op-
erating mode is selected.
OFF
The pump is switched off and remains off until a different op-
erating mode is selected. It will remain off even if a high-water
situation occurs.
AUTO
The pumps are switched on and off by the control unit depend-
ing on the water level. However, if there is dry-running protec-
tion, this will take priority over the automatic switching.
NOTE! If the control unit is password-protected, the password
must first be entered under "Settings" to change the operating
mode.
