Design and Functional Principle
2.5 Options modules
2.5.1 Options modules in normal and intrinsically safe versions
The options modules are protected and mechanically fixed by a module
cover ((1), see figure 2-10, page 28 and figure 2-11, page 30).
. NOTE
The housing must be opened to install the options modules. The
degree of protection IP65 is not guaranteed as long as the positioner is
open.
Opening the
instrument
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
J y -module
Insert the J y -module (3) in bottom pcb rails of the container, establish
the electrical connection with the enclosed ribbon cable (6).
Alarm module
Insert the alarm module (4) in the top pcb rails of the container,
establish the electrical connection with the enclosed ribbon cable (5).
SIA-module
(Slot Initiator Alarm module) Proceed as follows for installation:
1. Remove all the electrical connections from the basic electronics
(2).
2. Loosen the two fixing screws (2.1) of the basic electronics.
3. Snap out the basic electronic board by carefully bending the four
holders.
4. Insert the SIA-module (7) from above up to the top pcb rail of the
container.
