9. Operation

9.1 General
The D20 is operated by the yellow button.
Depending on desired action, press the
button:
- during a number of seconds (Ex:
or
- a number of times. (Ex:
All operation steps are indicated by lit or
flashing LED(s).

9.2 Startup

Connect Air supply and a mA-simulator
to the positioner.
Warning: During calibration, the
actuator may stroke unexpectedly.

9.3 Calibration

Run 4 mA current as input signal.
Press the button for 5 sec. (Re-
lease the button when the three
LED:s start to flash alternately).
5 sec.
The calibration starts, the
actuator goes go to max. and
min. position and calculates the
control parameters.
The Calibration procedure will take
between 30 seconds and some minutes
depending on actuator size.

This system will support the PMV D20, as
the voltage 12,5 V is greater than the required

Calibration
button
The three LED:s will flash alternately
during calibration.
After calibration all the three LED:s are
lit for a moment.
A successfull calibration is indicated by
yellow or green LED:
G
Green LED flashes = In service
Yellow LED flashes = In service.
Y
The unit vents in max or min posi-
tion.
An unsuccessfull calibration is indicated
by flashing red LED:
R
D20 does not reach the setpoint.
