4.6 Installing option modules
8. Set the limits L1 and L2 as described in the section "Installing the slit initiator alarm module
(SIA) (Page 60)".
9. An insulating cover (yellow) is required over the module. This insulating cover is supplied
with the module. Place the insulating cover on one side under the basic electronics seat of
the rack. The recesses of the insulating cover must fit in the corresponding webs of the
rack.
10.Place the basic electronics onto the four holders.
11.Fix the basic electronics using both the fixing screws.
12.Reestablish all electrical connections between the basic electronics and the option
modules. Connect the basic electronics and the option modules to the ribbon cables
provided. Connect the basic electronics and the potentiometer to the potentiometer cable.
13.Using both the screws, fasten the module cover provided. Do not use the standard module
cover.
14.Select the labels that are already present on the standard version of the module cover from
the label set provided. Affix the selected labels on the installed module cover as per the
standard version.
15.Proceed with the corresponding steps in the section General information on installing option

Procedure: Determining the switch status of the slotted initiators
You will require a suitable display device to determine the switch status. For example, use the
initiator tester type 2 / Ex from Pepperl + Fuchs.
1. Connect the display device to the following terminals of the SIA module:
– 41 and 42
– 51 and 52
2. Read the switch status of slotted initiators.
Procedure: Setting the L1 and L2 limits
The consecutive numbers in the following text refer to the above image in this section. Proceed
as follows to set the limits:
1. Move the actuator to the first desired mechanical position.
2. Adjust the upper actuating disk
changes. Set a high-low or a low-high switchover as follows:
