1. SAFETY
WARNING
This device can be used by children who are at least 8 years old and
by people with reduced physical, sensory or mental capacities or those
without knowledge orr experience, if they are properly supervised or
if they have been given instrcutions on safely using the device and the
associated risks have been understood. Children should not play with
the device. Children should not clean or perform manintenance ont he
device without supervision.
ELECTRICAL CONNECTIONS:
The electrical installation must be done by a qualified electrical engineer.
The device's power supply must be connected to ground (class I) and protect-
ed by a high sensitivity differential circuit breaker (30 mA). Devices without
plugs must be connected to a main switch on the power supply which discon-
nects all poles (contact separation distance of at least 3 mm). The connection
must be used exclusively to provide the power to the product.
If the power cord is damaged, to prevent possible danger, it must be replaced
by the manufacturer, customer service team or a similarly qualified individual.
Labelling of notes in the operating instructions
Danger
This term defines a high risk of danger, which can lead to death or serious
injury, if not avoided.
WARNING
Warning
This term defines a hazard which could cause a risk to the machine and its
operation, if it is not taken into account
Dangerous area
This symbol characterises hazards that could lead to death or injury.
Dangerous voltage
This symbol characterises dangers associated with the voltage and provides
information on voltage protection.
Property damage
This symbol, in combination with the keyword ATTENTION, characterises
dangers to the machine and its proper operation.
2. GENERAL INFORMATION
2.1 Areas of application
The twin pump control system ZPS 2.3 is principally used for the regulation of liquid levels. For this,
5
various sensors for level measurement can be used: floating switches, dynamic pressure, air bubble
level measurement systems, external 4- 20mA- sensors. The respective sensors to be employed can
be selected via the control program. Then two pumps are directly activated by motor contactors.
The pump changeover can be effected via time-control or level-control.
Furthermore, the following devices for error messages are available: acoustic signaler, 4 relay
alarm contacts potential-free (programmable for: high-water, combined fault, pump on, malfunction
pump, unit okay), safety circuits in the form of a turn-on- and a turn-off-delay, motor current
monitoring systems, motor temperature monitoring systems and flood control sensors guarantee a
safe operation of the pump station.
The control system is operated via 9 short travel key switches, the program settings are displayed
on an LCD display. All settings are saved so that they are available when the control system is
restarted. The display language can be changed.
Besides the actual operational parameters, the control system also saves the controlling process
and the occurring malfunctions in a record which can be displayed on the LCD display.

3. OPERATION OF THE CONTROL SYSTEM
The electronic pump control is equipped with a key lock. To unlock, please
press and hold (Selection) for 3 seconds. There will be an indication in
the display. Approximately 1 minute after the last actuation of any key the
keyboard will be locked again.
The automatic key lock after 1 minute can be deactivated in the menu, e.g. to
aid with maintenance works. The keylock is enabled with the service mode
switched-off only
3.1 Operator control panel and operational elements
3.1.1 Keys
(MANUAL)
By pressing this key, the preferred pump is switched on without delay. Except for
the motor monitoring, no other function of the program is enabled.
The green LED ③of one pump flashes. ATTENTION : If the ATEX mode is enabled,
the pump can only be started if the turn-on level is exceeded !
The green LED is flashing. ATTENTION : The pump will be switched after 2
minutes. A restart of the pump is possible immediately.
Stops the pump motor without follow-up. The green LED goes out.
The pumps are actuated via the level evaluation of the selected sensor (see
point 3.1.4). All monitoring and safety functions are executed according to the
presetting.
③Signal-LED indicating when the pump is
operating :
- green: pump is on
- red: fault

By pressing one of these two keys, the menu is switched to the next menu item in
the indicated direction.
If the menu is enabled, (see key SELECTION ), the set values can be modified
via those keys (some modifications are only possible in the operating mode
“Stop”). The more you press the key, the faster it scrolls.
(Selection/
Stop)
By pressing this key, the set values in the active menu are enabled. The activated
text will start to flash (modification mode) and can be modified by usin
g
.
By repeatedly pressing these keys, the set value becomes permanent (flashing
stops), which means that it will be saved even if the control system is turned off.
3.1.2 Indications on the display
Normal operation :
During operation of the control system, the upper line of the LCD display indicates the actual liquid
level or the switching status of the floating switch. In the lower line of the display, information about
the actual operational status of the control system of the pumps P1 and P2 will appear. If one pump
is running, the active motor current and the operating condition are displayed alternately. In case
of failure, the actual failure status is displayed (see point 3.1.6). The LEDs of the pump will flash
with a red light.
Parameter setting :
In the upper line, the designation of the parameter is displayed; the lower line displays the current
value of the parameter. The values can be modified by using the keys and as described
in 3.1.1.
Information retrieval :
Information values such as maintenance intervals, operating hours, pump starts and fault list can
be displayed and modified in the same way as the control parameters. Only the fault list saves 32
positions respectively. The recording is carried out by means of a shift register, which means that
the earliest error is deleted automatically.
3.1.3 Normal operation
During normal operation, the three operating modes are indicated on the display as follows.
Pressed key 2nd line on display Signification
Hand 1 P1 4,7A
Hand 2 P2 0,0A
The pump P1 and the pump P2 have been switched on
manually.
Stop 1 P1 0,0 A
Stop 2 P2 0,0 A
The pump motors are switched off. The level evaluation,
including the flood control, remains enabled.
The pump motor is not activated during
flooding alarm.

3.1.4 Parameter setting
The following table shows the setting options and the effects of the individual parameters. A
parameter can be selected via the menu selection (see point 3.1.1).
For reasons of safety, the modification mode for the parameters can
only be enabled in the "Stop"- operation (key ).
