Operating the device
The local control of the device is described by means of the type
PAN 1
detachable operator
panel.
Button
allows you to change the control location: Remote, Local, Off. By pressing the button a cyclical
change of control position is made: Remote -> Local -> Off -> Remote -> …
The selected control location is indicated by the corresponding LED.
The selected control location is stored in the SEM SC11 controller.
After the power supply is restored, the last selected state is also restored.
Control mode:
LOCAL - local operator control
If there are no control locks (resulting from the operation logic), buttons
,
generate pulses of a certain
duration to the output controlling the switching apparatus.
Control mode: REMOTE - telemechanics control
Action of buttons
,
is overridden. The switch control takes into account the control interlocks resulting
from the logic of operation implemented in the controller, via communication links located in the controller.
Control mode:
OFF - no control capability
The action of buttons
,
and control commands from the telemechanics are overridden – control lock.
In the absence of the ability to control the switching apparatus as resulting from a jam in the
control procedure (a blocking of the switching apparatus) in a transient state, the device has a
mechanism for local and remote unlocking of switches with the “open” button.
The logic of operation of the device is based on the ELF software and is freely editable by the
user.
