The alarm module has the following features:
● Available in two versions.
– Explosion-proof version for connecting to a switching amplifier in conformity with
EN 60947-5-6.
– 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 has dual functionality. Both inputs are implemented as logical OR
combination.
– Potentially separated for voltage level
– Not potentially separated for floating contacts
You are familiar with the general procedure described in the chapter "General information on
installing option modules (Page 48)".
Procedure for installing the alarm module
1. Slide the alarm module into the rack below the basic electronics . Ensure that you slide it
up to the end stop.
2. Connect the module to the basic electronics. For this purpose, use the 8-pole flat ribbon
cable provided.
Slot initiator alarm module
Function
If the standard controller requires electrically independent limit value messages, the slotted
initiator alarm unit with slotted initiators is used instead of the alarm unit.
● A binary output is used to display a collective fault message. Compare with the function of
the alarm unit. 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.
