1Introduction
Dear customer,
Congratulations on the purchase of your control system. We are confident that it will meet
all of your requirements. We trust that the unit will give you trouble-free and successful
service.
The plug’n’dose AM dosing system consists of a dosing control and a dispenser. It has
been developed and tested for precision operation with our dispensers.
We would appreciate your assistance in our efforts to maintain the highest possible
quality standards. Please send us any suggestions you may have on ways that we may
further improve our products.
2Function description
The plug’n’dose AM control system controls the dispenser according to the signals that
are generated by the master controller. This means that both the dosing quantity1) and
the suck-back1) are adjustable.

4.5 Organisational measures
The necessary personal protective equipment must be
provided by the operating organisation. All safety devices
that are fitted must be checked regularly. Safety glasses
and overalls must be worn during operation and cleaning
to provide protection against any splashes of chemicals.
All of the safety information contained in the respective
operating and maintenance instructions for the dispenser(s) that are connected to the
control system must be complied with.
4.6 Preparing to operate - visual inspection
The control system must be visually examined each day before the start of work and
before all shift changes. If there is any doubt as to the system's readiness for operation,
it must be shut down immediately and inspected by a specialist before operation
resumes.
4.7 Preventing damage to the dispenser motor
The dispenser lead (connector 3, Chapter 5.1, Displays and controls /
connections on page 7) may only be connected and disconnected when the
power supply is isolated. The electronics in the drive motor could be damaged
if this precaution is not taken.

5.3 Important for signal definition
The amount of medium that is drawn back in by the suck-back must only be just enough
to prevent dripping.
If more is sucked in, air will enter the dispenser and the medium will emerge late at the
next dosing.
Caution: If the suck-back is set higher than the dosing, the dispenser may be damaged
by running dry.
5.4 Starting up
• Ready the dispenser for operation in accordance with the supplied commissioning and
maintenance manual.
• Plug in the connector (3) of the dispenser (D)
• Connect (1) the cable of the master controller1) (B)
Notice: The control system is only ready for operation when the dispenser is connected.
• Fill the dispenser with medium as directed in its operating and maintenance
instructions.
Caution: The dispenser lead (connector 3) may only be connected and disconnected
when the power supply is isolated. The electronics in the drive motor could be damaged
if this precaution is not taken.
Only use the original connection and cable between Dispenser (D) and plug (3).
1) after it has been connected to the master controller
Caution: Do not switch on control system until medium has been delivered to it.
Otherwise there is a risk of damage to the equipment. Even a short test run can cause
irreparable damage to the stator.
