Fig. 44: SKU 2 x 3 A
Attention!
SKU modules must never be
plugged in or removed in „On“
switching state!
Deactivate an SKU module via
the ST 20 E control unit before
removing it for testing, inspec-
tion or other purposes.
For mounting work the control
system must be blocked to pre-
vent active circuits from being
switched on when plugging in
an SKU module.
Figure 44 shows a SKU 2 x 3 A. These
SKU bus modules combine two circuit
changeover units into a single device.
As regards look and location of the
indicating and control elements refer to
Chapter 14 „Control“. These modules are
also available with a single circuit (refer to
Fig.: 44a SKU 1 x 6 A).
As regards mounting and removing an
SKU unit proceed as described against
„11.7 Mounting and Connection of Inter-
nal Modules“.
For replacements, extensions or for te-
sting purposes SKU modules have to be
exchanged or added.
In this context observe the following:
The circuit numbers and indicated
switching outputs of the SKUs shown
on the indicating display of the ST
20 E control unit correspond to the
selection of the slots of the subracks
(BGTs).
In order that replaced SKUs function
properly within the control system
they have to be identified, activated
and parameterized by means of the
control software.
