1. Introduction
The PMV D3 is a digital positioner de-
signed primarily for controlling adjustable
valves.
The positioner can be used with single or
double action actuators with either rotary or
linear movement.
The D3 can be equipped with modules
for feedback, limit switches, and a pressure
gauge block.
Safety instruction
Read the safety instructions in this manual carefully before using the product. The
installation, operation, and maintenance of the product must be done by staff with the
necessary training and experience. If any questions arise during installation, contact
the supplier/sales office before continuing work.
Warning
• The valve package moves when in operation and can cause personal injury or damage
if handled incorrectly.
• If the input signal fails or is switched off, the valve moves quickly to its end position.
• If the compressed air supply fails or is turned off, fast movements can occur.
• The valve is not controlled by the input signals when in the Out of service mode. It
will open/close in the event of a leak.
• If a high value is set for Cut off, fast movements can occur.
• When the valve is controlled in the Manual mode, the valve can move quickly.
• Incorrect settings can cause self-oscillation, which can lead to damage.
Important
• Always turn off the compressed air supply before removing or disconnecting the air
supply connection or the integral filter. Remove or disconnect with care because C- is
still under pressure even after the air supply is turned off.
• Always work in an ESD protected area when servicing the PCB´s. Make sure the
input signal is switched off.
• The air supply must be free from moisture, water, oil and particles.
The modules can be factory assembled
before delivery or fitted later.
The modules for feedback and limit
switches can contain the following:
Feedback 4-20 mA and one of the
following functions:
- Two mechanical contacts
- Two reed switches
- Two inductive sensors, DIN 19234
