Control operation-local mode
The operator panel is located inside, and at the top, of the
control cabinet. The operator panel contains the power
toggle switch, the SCADA toggle switch, the motor select
knob, the operation switches, and the status indicators.
(See Figure 4).
Local mode operation
Status and control operation are provided via the operator
panel. The control is activated in the LOCAL mode when the
SCADA toggle switch is set to LOCAL.
Operations capabilities from the control panel:
●
●
Select local or remote operation.
●
●
Select one of several motors.
●
●
Read status of selected motor.
●
●
Operate the selected motor.
●
●
Monitor opening or closing action.
●
●
Test indicating lights.
●
●
Read status of 120 Vac.
●
●
Disconnect 120 Vac.
●
●
Test battery (with user-supplied volt meter).
●
●
Disconnect 24 Vdc.
Local mode features
Features and capabilities of the DC motor operator
control, which can be accessed from the control panel, are
described as follows:
POWER SWITCH (ON/OFF TOGGLE)e:
Disconnects the DC
voltage to the control and motors. When the Power switch
is in the OFF position, all control features are inactive with
the exception of the battery test feature. The AC supply will
be unaffected.
SCADA SWITCH (TOGGLE)e:
In the Local position, prevents
the operation of Open, Close, and Motor selection from
the SCADA terminals. Operation of the motor operator is
only possible from the control panel. Conversely, placing
the SCADA toggle switch in the REMOTE position prevents
the operation of Open, Close, and Motor selection from
the control panel. Operation of the motor operator is only
possible via the SCADA terminal points. (Also see Control
Operation-Extended Control).
MOTOR SELECT SWITCH (ROTARY)e:
Selects which motor
is active for status indication and operation. This switch
should be returned to the OFF position after operation is
completed to disable the panel indicating lights so as to
avoid battery drain.
CLOSE (RED PUSH BUTTON)e:
Closed 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
and 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.
otee:
N
Do not move MOTOR SELECT switch during motor
operation as motor will halt partially operated and
actuation may transfer to new motor selection.
Do not leave motor partially operated. The interrupter
may be on the verge of operating. Complete actuation
to either the fully open or fully closed position.
IMPORTANT
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 push button .
Battery charger board
The battery charger, battery test pushbutton, AC indicator
light, fuses, and 120 Vac terminals are located inside, and
at the bottom of, the control housing. See Figures 2 and 3.
The charger board can receive 120 Vac from either of the
two 120 Vac sources which can be connected simultaneously
through the supply terminals (See Figures 2 and 3). Each
120 Vac supply is fused on the board with a 1A fuse.
