2.6.5 SIA module
Function
Installation
38
The SIA module contains three digital outputs.
A collected fault message (see alarme module) is output via a digita-
loutput. The floating digital output is implemented as a self error repor-
ting semiconductor output.
The other two digital outputs are used for reporting two mechanically
adjustable limit values (L1, L2) by slot initiators. The two binary outputs
are electrically independent of the rest of the electronics.
(Slot Initiator Alarm module) Proceed as follows for installation:
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 up to the top pcb rail of the
container.
5.
Push the SIA module in the pcb rail of the container about 3 mm to
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 correspon-
ding 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).
9.
Make all the electrical connections between the motherboard and
the options with the ribbon cables provided and between the mo-
therboard and potentiometers with the potentiometer cable.
10. Fix the enclosed module cover instead of the standard version with
the two screws (1.1).
