Testing the control
functions
The selected bay type is displayed on the Bay Panel. The activation of the Bay Panel
display is described in Chapter 6. If the position signals of the switchgear units are
connected correctly to the C232, then the updated switching status of the switchgear
units will be displayed on the bay panel. If the switching status is not displayed correctly,
the user can check the physical state signals of the binary inputs to determine whether
the status signals in the C232 are correct (this can be checked at INP: State U xxx,
'Oper/Cycl/Phys').
Switching from local to
remote control
Switchgear units can be controlled locally using the keys on the local control panel,
remotely through the communication interface, or through appropriately configured
binary signal inputs. The control point – Local or Remote – is selected either by means
of the L/R key on the local control panel or via an appropriately configured binary signal
input. If a binary signal input has been configured, then the L/R key has no effect.
Switching from Remote to Local using the L/R key on the local control panel is only
possible if the L/R password has been entered first (see additional instructions in
Chapter 6). The selected control point is displayed on the Bay Panel.
Local control
The switchgear unit to be controlled is selected by pressing the Selection key on the
local control panel and then controlled by pressing the Open or Close key. If the
switchgear units are to be controlled through binary signal inputs, then the appropriate
signal input must be triggered.
Remote control
The switchgear units can be controlled via the communication interface or appropriately
configured binary signal inputs.
Switchgear unit not
responding
If a switchgear unit does not respond to a switching command, it could be due to the
following factors:
The general control enable – if configured – has not been set.
(configuration at MAIN: Inp.asg. ctrl.enabl., 'Par/Func/Glob' folder)
Interlocking has been triggered.
(This can be checked at MAIN: Interlock equ. viol., 'Oper/Cycl/Log/'.)
For bays with direct motor control only:
Motor monitoring has been triggered.
(This can be checked at MAIN: Mon. mot. drive s tr., 'Oper/Cycl/Log/'.)
