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.

3.2 Assembly and electrical connections
All electrical connections are to be established by an authorised
professional only. Settings and adjustments on the control system
as well as the commissioning of the control system are to be
carried out by qualified persons only.
3.2.1 Mechanical fixation
The control system has to be fixed on an even surface. In order to fasten the control system, the
housing cover has to be opened.
3.2.2 Mains connection
The left cable gland is intended for the cable entry of the mains cable. The separate cables are
to be clamped into the spring terminals in the manner described below. According to the motor
which is used, a single-phase or a three-phase connection can be established.
The power supply has to be secured by an independent all-pole
fuse which can be switched off (max. 20 A).
3.2.3 Connection of the pump motor
Either mono-phase or three-phase motors may be connected according to the below shown
connection diagram.

3.2.4 Connection of the external sensors
The external sensors are connected by means of the terminal strip on the upper circuit board.
The active sensor can be selected in the menu “level control” and “therm. malfunction”.
If the thermostatic switches TH2 and TH4 are not necessary, bridges have to be inserted on those
contact points. The thermostatic switches TH1 and TH3 can be deactivated via the menu therm.
malfunction.
The floating switches have to close when they are floating on the surface. The floating switches
have to be connected floatingly. The required signal voltage is generated in the control system and
amounts to 5V.
Assignment of the float switches:
SWN1 = pumps 1 and 2 off
SWN2 = pump on
SWN1 = peak load 2nd pump switched on
SWHW = high water alarm
For the usage in explosion-prone areas, either floating switches with the
corresponding permission, or intrinsically safe cut-off relays have to be
used.
The external sensor has to supply a measurement current between 4
and 20mA. The final value of 20 mA can be adjusted in the menu, so the
indication may occur in cm.
3.2.5 Utilisation of the internal sensor
An internal sensor, a pressure sensor 0 to 10 kPa is used (0 to 1mWs, 0 to 100 mbar). Other
measurement ranges can be realised on demand. On the lower side wall, a hose screw connection
6/8mm is located which is intended for the connection of the immersion pipe. The sensor used
is designed as a differential pressure converter, so that barometric variations are eliminated. The

menu item “internal converter – adjustment” serves for the accurate adjustment of the zero point.
In order to equalise possible air leaks inside the pneumatic level
measuring device, the pilot tube has to be fully emerged from the water
after completion of the pumping process. For this purpose, the adjustment
of a follow-up time of the according duration is necessary. Alternatively,
the small-size compressor set for the air bubbler level measurement
system can be used.
3.2.6 Signal contacts
The 4 potential-free signal contacts are located in the upper circuit board (left).
The 4 signal contacts are free programmable: the contacts 1 and 2 are opened in case of power
failure and the contacts 3 and 4 are closed in case of power failure.
If the power supply of the control is okay, then the signal contacts are closed in case of a fault or
signal.
3.3 Commissioning of the control system
After the complete connection of the pump cables, the mains power supply and the level sensor,
the parameters can be set after the mains voltage has been applied. Only trained personnel are
allowed to set those parameters.
Now the plant can be commissioned by pressing the key . During the conduction of several
test runs, the set switch points have to be checked, and, if necessary, corrected.
Checking of the control system without pumps :
In order to be able to check the control system without a pump, the following standard settings are
required :
1. Connect the control system to a single-phase network (connection of N and L1)
2. Set motor current limitations for both pumps to 0.0 A
3. Switch off rotary field
4. Bridge thermal contacts TH2 AND TH4
5. Disable thermic error for pump 1 and pump 2.
If the respective level sensors are connected, all program functions can be checked without having
to connect the pumps.
4. DISPOSAL
Only for EU-countries
Do not dispose of the control system with the regular household garbage!
According to the European directive 2012/19/EG about waste electric and
electronic equipment and the transposition into national law, used electric tools.
have to be collected separately and recycled in an environmentally compliant
manner.

2. ALLGEMEINE ANGABEN
2.1 Anwendungsgebiete
Die Doppelpumpensteuerung ZPS 2.3 wird vorwiegend zur Regulierung von Flüssigkeitsniveaus

19
eingesetzt. Dabei können verschiedene Fühler zur Niveauerfassung eingesetzt werden:
Schwimmschalter, Staudruck, Lufteinperlung, externe 4- 20mA- Sensoren. Die jeweils zum Einsatz
kommenden Fühler können im Steuerprogramm ausgewählt werden. Motorschütze steuern dann
direkt zwei Pumpen an. Der Pumpenwechsel kann dabei zeit- oder niveaugesteuert erfolgen. Zwei
einstellbare Schaltniveaus gestatten den gleichzeitigen Betrieb beider Pumpen.
Weiterhin stehen folgende Einrichtungen zur Störungsmeldung zur Verfügung:
akustischer Signalgeber, 4 Relaismeldekontakte potentialfrei frei programmierbar (für Hochwasser,
Sammelstörung, Pumpe ein, Störung Pumpe, Anlage in Ordnung), Sicherheitsschaltungen in Form
vonEinschalt-undAusschaltverzögerung,Motorstromüberwachung,Motortemperaturüberwachung
und Hochwassersensoren gewährleisten einen sicheren Betrieb der Pumpenanlage.
Die Bedienung der Steuerung erfolgt über 9 Kurzhubtasten, die Programmeinstellungen werden
über ein LCD- Display angezeigt. Sämtliche Einstellungen werden gespeichert und stehen beim
Neustart der Steuerung wieder zur Verfügung. Die Landessprache im Display ist umschaltbar.
Die Steuerung speichert neben den eigentlichen Betriebsparametern auch den zeitlichen
Steuerungsverlauf und die auftretenden Fehler in einem Protokoll, das im LCD-Display angezeigt
werden kann.
