Extended control accessory
The DC Motor Operator control can be operated via
a separate portable control when equipped with the
appropriate accessory components. The Extended Control
Accessory components include the portable control, the
control cable, and modifications to the DC Control (ie: an
additional connector and associated wiring). The cable is
supplied with a separable connector at both ends and can
be supplied in user-specified lengths up to 200 feet.

Modifications to the DC Control should be made at
time of manufacture, but can be purchased optionally
as a field retrofit kit.

Extended control accessory operation
The DC Control can be optionally equipped with an
accessory which allows the control to be operated (in the
LOCAL mode) from an additional portable control panel.
Monitoring and operation are provided through the extended
control accessory.

Control operation – extended control
With the DC Motor Operator Control SCADA toggle switch
set to LOCAL and the rotary MOTOR SELECT switch set
to the OFF position, the operation capabilities from the
extended control accessory are:
●
●
Select one of several motors.
●
●
Read status of selected motor.
●
●
Operate the selected motor.
●
●
Monitor opening or closing action.
●
●
Test indicating lights.
The operation of each feature is described as follows:
MOTOR SELECT SWITCH (ROTARY)e:
Selects which motor
is active for status indication and operation by the extended
local control. The SCADA switch must be set to the
LOCAL position for extended local control operation.
CLOSE (RED PUSH BUTTON)e:
Closes the selected switch
or interrupter mechanism, via the motor operator.
OPEN (GREEN PUSH BUTTON)e:
Opens the selected
switch or interrupter mechanism, via the motor operator.
STOP (YELLOW PUSH BUTTON)e:
Stops the motor-
operated opening or closing action of the selected switch or
interrupter mechanism.
otee:
N
Mechanisms should not be left between an open
or closed position. A mis-operation could occur.
Restart the motor and actuate to a fully OPEN or
fully CLOSED position.
LAMP TEST (WHITE PUSH BUTTON)e:
Checks status
indicator lights by energizing all lights.
CLOSED INDICATION (RED LIGHT)e:
Indicates that
the selected switch or interrupter mechanism is in the
closed position.
OPEN INDICATION (GREEN LIGHT)e:
Indicates that the
selected switch mechanism is in the open position. It also
indicates that the fault interrupter mechanism is in either
the open or tripped position.
CLOSING INDICATION (YELLOW LIGHT)e:
Indicates
that the motor actuator is closing the selected switch or
interrupter mechanism.
OPENING INDICATION (YELLOW LIGHT)e:
Indicates
that the motor actuator is opening the selected switch or
interrupter mechanism.
Important Notee:
The VFI mechanism is a trip-free
mechanism. If the VFI is closed by a motor operator and
a fault occurs, the handle will be held in the CLOSED
position, but the VFI mechanism will trip and the control
panel will indicate OPEN. To reset the VFI, select the correct
motor and push the OPEN pushbutton. The motor operator
will open and reset the VFI. The VFI can then be closed by
pushing the CLOSE pushbutton.
