Installing The Slit Initiator Alarm Module (Sia) - Siemens SIPART PS2 Operating Instructions Manual

Installing/mounting
4.6 Installing option modules
The alarm module has the following features:
● Available in two versions.
– Explosion-proof version for connecting to a switching amplifier in conformity with
– Non-explosion-proof version for connecting to power sources having a maximum of 35 V.
● Three binary outputs. Binary inputs are potentially separated from the basic configuration
and from each other.
● The binary input BIN2 has two inputs. Both inputs are implemented as logical OR
combination.
– Input 1 at terminals 11/12: Is electrically isolated, and is triggered by an active signal.
– Input 2 at terminals 21/22: Is not electrically isolated, and is triggered by a passive NO
Procedure for installing the alarm module
1. You have performed the steps described in the section General information on installing
option modules (Page 51).
2. Slide the alarm module into the rack below the basic electronics . Ensure that you slide it
up to the endstop.
3. Connect the module to the basic electronics. For this purpose, use the 8-pin flat ribbon
cable provided.
4. Proceed with the corresponding steps in the section General information on installing option
modules (Page 51).

Installing the slit initiator alarm module (SIA)

Function
If the standard controller requires electrically independent limit value messages, the slotted
initiator alarm module with slotted initiators is used instead of the alarm module.
● A binary output is used to display a collective fault message. Compare with the function of
the alarm module. The floating binary output is implemented as an automatic fault indicating
semiconductor output.
● The other two binary outputs are used to signal the two limits L1 and L2 which can be
adjusted mechanically using slotted initiators. Both these binary outputs are electrically
independent from the remaining electronic unit.
