1. Safety Precautions
Before installing and commissioning of the pump controller, please read the product manual carefully and
observe all warnings and safety instructions. Keep this manual is always easily accessible in the vicinity of
the frequency converter controller.
Definition of Information
Warning!
In disregard of the safety instructions may lead to serious and life-threatening bodily injury
or property damage occur, a significant!
Caution!
Failure to observe these instructions may lead to serious and life-threatening bodily injury
or property damage occur, a significant!
Notice!
Failure to observe these instructions may lead to malfunction of the plant!
Warning!
The frequency inverter controller generates dangerous electrical voltages and controls
potentially dangerous rotating mechanical parts.
Warning!
The installation, Initial Settings and maintenance of these drives can only be by qualified
personnel who are familiar with the operation, carried out.
Warning !
Give special care when automatic restart is enabled. To prevent injuries caused by any
inadvertent restart of inverter controller after a power failure, turn off in case of doubt the
automatic restart. For repair and maintenance work at the plant, you notice that the system
can not be turned on by other again!
Warning!
The frequency inverter controllers have the lead after the mains off dangerously high
voltage. Wait, therefore, after switching off the mains for at least 5 minutes before you work
on the device. It is important to ensure that no live parts are touched, or when voltage is
applied between the capacitors are charged. Do not work on the wiring and make sure no
signals when voltage is applied.
Caution!
All pump controllers are tested for dielectric strength and insulation resistance. Be
disconnected before the isolation measurement on the pump unit, for example, as part of the
inspection, the frequency control!

2. General / Mode of Operation
2.1 MA .... Pressure Control System
Congratulations on purchasing this high-quality pump control. This product complies with the latest
technology and is continually developed and improved. The device was subjected to the production of an
extensive examination and therefore functions properly. To read to ensure optimal function and observe these
operating instructions.
This frequency inverter controller operates as an automatic pressure regulator, tested.
The speed of the pump (s) will be adjusted continuously. The actual pressure in the system is determined by
pressure transducer (sensor). A PI controller regulates the pressure by analogy.
The pressure regulator is programmable and can be adapted to the respective operating conditions. The
parameters are displayed on the display in plain text. Commissioning is menu driven. During
commissioning, some data must be entered to ensure the smooth operation of the pumping plant. An
adjustment of specific parameters (expert mode) requires special knowledge of pump technology. This
should be done by a competent person or the manufacturer.
2.2 Benefits of speed control:
- almost constant pressure
- Continuous adjustment of pump power to the changing operating conditions
- Energy saving
- a speed-double unit replaces a four-fold pressure switch system
- low mechanical wear of the pumps
- Maintenance
2.3 Principles of pressure control
To operate a speed control can be accurately and effectively, the following points to consider:
-the pump (s) must be construed in accordance with the plant / Requirement
-the pump (s) shall have power reserves available (80. .90%) = system reserve capacity at rating
-with submersible pumps must be based on an output reduction of about 5. .10%
2.4 Construction of a pressure control system
Non-return valve preventer is imperative and must be in the pressure behind the
Pump will be installed! The expansion tank is to be fitted if required.

Caution!

2.5 Note for the operation of the system with Pressure vessel!
If the plant is operated with a pressure vessel, the vessel must be pre-pressed in normally state.
The pre-squeezing pressure should be checked regularly. The amount of pre-squeezing pressure is: Start
pressure bar minus 0.20.
e.g.: Nominal System Pressure: 4.00 bar
Vessel Air Pressure: 3.80 bar
2.6 Booster Sets
Booster units are ready plumbed and wired pump installations. For them, the installation cost
is minimal - connect to the existing network of pipes, mains and commissioning. The
regulator is factory set at these facilities.
This manual refers only to the electrical control of the system is therefore possibly the pump
consult the manual (s) note the / partition.
See manufacturers data sheet.
3. Installation and Mounting
Environmental conditions such as high temperatures, high humidity should be avoided as well as dust, dirt
and corrosive gases. The installation should be a well-ventilated and not exposed to direct
sunlight location.
Because of convection, the frequency control during installation of at least
Be installed 15 cm from side walls or other facilities.
The allowable temperature range of +5 ° C to +30 ° C must not be under-or exceeded.
Do not install the Inverter controller near heat-radiating bodies.
3.1 Mounting the MA.... Controller

an expert who is familiar with the pump system will be implemented.
Shielded cable! Screen to the grounding clamps in the cabinet and connected to the pump!
For submersible pumps combine the screen with a ground potential in the vicinity of the
pump.
Do they no mains power to the sensor - or control terminals.
No manipulation of the sensor signal to make!
No other users connect to the 24V supply!
The used pressure sensor (0. .10 V) or (4. .20 mA),
is connected to the respective terminals!
The respective pin assignment, refer to the respective diagram.
In systems with several pumps are used again and 0. .10 V sensors.
Here you can optionally one or more sensors are connected.
The respective pin assignment, refer to the respective diagram.
Notice!
If the motor cable longer than 100 meters, it is advisable to install an motor reactor.
Caution!
Verify the correct connection of the network, sensor, and control lines.

10. Expert mode
10.1 Dry run protection
If the internal slide switch set to "dry run", the pump (s) monitored at all times in automatic or hand mode
to "dry run". The pump (s) are stopped when the system pressure of 0.5 bar in 60 seconds is not reached.
10.2 Electronic low water protection
The electronic "water protection" is a pressure monitoring.You to monitor the system pressure in automatic
below. The pressure monitoring will be active after the fill mode. The fill mode is active again after every
interruption. The system pressure falls below the switch pressure „On“ by 50% for longer than 3 minutes,
off the system.
10.1 Pump change
Which of the pump first starts up, is not defined.To ensure smooth operation of the pumps, all operating
cycles or at least every 24 hours, the master / slave - changed operation. If a pump is stopped or fails due to a
defect, the master will switch status.
10.2 Forced pump change
Opening external release contact is changed, the master and slave. Now can be treated in the same way with
the new master.

10.3 Dynamic Operation Mode (DY)
The mode "DY" provides for the safe shutdown output "0 " during operation of the pump system
without the expansion tank or a very small expansion tank..
In the mode "DY" turns the pump on the pressure (!) and off to output "0 "!
Using the rotary switches A, text "ON", set the starting pressure of 0-100%. You should adjust the pressure
„On“ switch as low as possible.
The rotary switch B, text "OFF", set the sensitivity (!) of the switch-off between 0-10%. The pressure-Off
with the switch-off form a mathematical combination.
The logic of the mathematical combination is:
Off pressure = measured pressure measurement cut-up time + - = Switch-off standby.
Off The pressure is calculated after each switching cycle On / Off "again (!).
The rotary switch T, text "TIME", set the delay time between 5 sec and 30 sec,
to the output "0" off point to reach safely.
The mode "DY" requires some experience in recruiting and detailed knowledge of the operation of the pump
controller. If the system working satisfactorily, please contact a dealer or manufacturer.
This setting trace across the display.
To set the switch-off knowledge is required!
10.4 Reset the operating hours
