Control power
The control requires a 120 Vac (104-127 Vac) to operate the
battery charger. An additional 120 Vac input with a flip-flop
relay will be provided for preferred/alternate voltage sources
(See Figures 2 and 3).

Description of control
Control operation
The DC motor operator control is designed for use
with Eaton’s Cooper Power series Type RVAC and VFI
pad-mounted switchgear. The motor operator control is
applicable with both 600 amp vacuum loadbreak switch
mechanisms and vacuum fault interrupter mechanisms.
The motor operator control is designed to monitor and
direct the operation of DC motors when supplied with
Type RVAC and VFI pad-mounted switchgear. The control
will operate up to six motor actuators-one at a time-in a
user-selected random order for 25 OPEN and 25 CLOSE
operations without line voltage.

The basic DC control can be operated in either the LOCAL
or REMOTE modes by making the appropriate selection
with the SCADA toggle switch. With the SCADA switch on
LOCAL, STATUS and control functions are accessed via the
control panel. With the SCADA switch on REMOTE, STATUS
and control functions are accessed via the SCADA interface
(See Figures 4 and 6).
Auxiliary contacts
One “a” and one “b” auxiliary switch contact from the “B”
phase of each actuated mechanism are utilized for status
indication. To read status in either LOCAL or REMOTE
modes, a motor must first be selected.
Simultaneous indication for SCADA
For some SCADA applications, it may be necessary to
monitor the status of each stage simultaneously. To
provide this capability, an additional stage for each actuated
mechanism is required. For these applications, an optional
interface, separate from the control, can be additionally
provided (consult factory for details).
Electrical interlocks
The DC motor operator control may be supplied with the
capability for user-specified electrical interlocking. For these
applications, an additional stage may be required (consult
factory for details).
