Johnson Controls MP8 20 Series Manual

General
These service and data information (in brief SDI)
are operating instructions and contain instructions
for the safe installation and operation of the
pneumatic actuator. Should difficulties occur,
during installation, which cannot be solved with the
help of this SDI please ask your supplier for further
information.
These SDI are in accordance with the relevant
safety standards and regulations of the EU. When
operating the positioner outside the Federal
Republic of Germany, it is the responsibility of the
control system administrator or operator to ensure
that valid national control standards are met. The
manufacturer maintains all rights for technical
changes and improvements at any time Operators
are to receive instructions in accordance with this
SDI.
Qualified personnel
These are persons conversant with the erection, installation, commissioning, operation and service of the
product and in possession of the respective qualifications through their activities and functions, e.g.:
•
Instruction about and obligation to maintain adherence to all operative regional and factory-internal
directives and requirements, conditional to application.
•
Training or instruction in accordance with standards of safety in maintenance and utilisation of adequate
safety- and protective equipment.
•
Training in first aid, etc. (See TRB 700).
Application:
Diaphragm actuators in conjunction with control valves serve to regulate the flow of fluids in heating systems,
cooling systems and cold water systems. The stroke action distinguishes between direct or reverse action
actuators. Decreasing actuator air pressure allows the stem to be retracted by spring force. The term
"reversible actuator" means that it is possible to change the action of the actuator in-situ, with a conversion
kit. When converting the action of an actuator with hand wheel, the action of the hand wheel must be taken
into account. A pneumatic positioner (PR 10) can be used to regulate the stroke.
Valve and actuator application, are the responsibility of the control system administrator. Particular markings
on the valve with actuator such as flow directional arrow are to be observed.
Dry compressed air is an absolute requirement during usage in below zero temperatures!
Valve and actuator may be supplied as single units or as valve / actuator combinations, factory mounted and
tested.
