2.7.5 SIA module

The SIA module contains:

S

one binary output

S

two binary outputs

A collected fault message (see alarme module) is output via the binary

output. The floating digital output is implemented as a self error report-

ing semiconductor output.
The two binary outputs are used to report two mechanically adjustable

limit values (L1, L2) via slot initiators. These two outputs are electrically

independent of the rest of the electronics.

(Slot Initiator Alarm module) Proceed as follows for installation

(figure 2-11, page 28)::
1. Remove all the electrical connections from the motherboard (2).
2. Loosen the two fixing screws (2.1) of the motherboard.
3. Snap out the motherboard by carefully bending the four holders.
4. Insert the SIA module (7) from above until it reaches the upper

circuit board rail of the rack.

5. Push the SIA module into the circuit board rail of the rack approx.

3 mm towards the right.

6. Screw the special screw (7.1) through the SIA module into the axle

of the positioner (Torque: 2 Nm):

CAUTION
The pin pressed into the actuating disc bearing (12) must be adjusted

to just before touching with the special screw. The actuating disc bea-

ring and the special screw must then be turned simultaneously so that

the pins slot into the special screw.

7. Place the insulating cover (10) over the SIA module underneath

the surface of the motherboard at the container wall on one side.

The recesses in the insulating cover must slot into the correspond-

ing lugs on the container wall. Place the insulating cover on the

SIA module by carefully bending the container walls.

8. Snap the motherboard into the four holders and screw it tight again

with the two fixing screws (2.1).
