The following option modules are available for the positioner in the
standard and the intrinsically safe version:
-- l -module
y
-- Alarm module
-- SIA-module
-- Mechanical limit switch module
-- EMC filter module
The installation of the options modules is described below:
The option modules are secured by a assembly covering ((1), see
figure 2-11, page 28) and mechanically fixed.
NOTE
To install the option modules the housing of the positioner needs to be
opened. As soon as the positioner is opened, the IP66 degree of
protection is not guaranteed.
To open the positioner, the four screws of the housing cover must be
loosened with a Phillips screwdriver.
Disconnect or isolate the power supply cables.
Remove the module cover (1). To do this, the two screws (1.1) must be
removed with a screwdriver.
NOTE
To prevent premature wearing of the fixture by the self-tapping screws
(1.1), the following method of mounting the module cover (1) has
proven effective.
1. Turn the screws counterclockwise until you feel them snap into the
thread
2. Tighten both screws carefully in clockwise direction
