A typical driver consists of the central module
SEM SC11
. The module has two links: X31 (RS-485) for
connecting with the telemechanics or module
SEM SB11
and X41 (PANEL) for connecting the HMI Panel.
The device operation can be monitored and controlled through both links. The telemechanics functions can be
performed by the
SEM Cxx
module which is equipped with tools for communication with SCADA systems. For
local control of the device,
PAN 1
or
PAN 3
type detachable operator panels are used.
All modules are supplied with DC 24 V. If there is a separate power supply in the switchgear for
the commutating device control and the telemechanics, use the
SPS 24-1
type power switch which switches the
SEM SC11 to the standby power (from the telemechanics) in the absence of a control voltage.
-
In this case,
the control of the switch is blocked, but its status can be monitored and data exchange with the telemechanics
is possible.
