Instructions for LOCAL mode operation
For DC Motor Operator Control wiring and outline
information, refer to Figure 5 and 8.
1 . POWER switch must remain ON for normal
operation . Power OFF disables both control
and motors .
The power switch is a 5-amp, DC breaker which will
operate in 1 to 3 seconds for 20 amps. Placing the
switch in the OFF position disables the DC, which
powers both the control and the motors.
2 . SCADA switch must be set to LOCAL .
To operate the motors from the control panel, the
SCADA switch must be set to LOCAL.
3 . Set MOTOR SELECT switch to desired motor .
To read contact status or to select a motor to operate,
set the MOTOR SELECT switch to the desired position.
4 . Confirm correct status indicators are lit .
After selecting a motor, confirm that the status lights
indicate the actual position of the mechanism.
5 . Push OPEN or CLOSE pushbuttons to operate
motor . Yellow light indicates motor operation
in progress . Push STOP to halt motor operation
immediately; then push OPEN or CLOSE to
complete a full open or full close operation .
(See Note below) .
Push the appropriate pushbutton to perform the OPEN
or CLOSE operation. If necessary, push the STOP
pushbutton to halt the motor immediately. Do not leave
the motor in this condition. Complete a full OPEN or
CLOSE operation to prevent an inadvertent mechanism
operation.
6 . When complete, return MOTOR SELECT switch to
OFF . Set SCADA switch as desired . Leave POWER
switch ON to permit SCADA operation .
The status lights will remain lit as long as a motor
is selected. If AC power is lost, the batteries will
eventually be drained. Be sure to return the MOTOR
SELECT switch to the OFF position. Leave the POWER
switch on if SCADA operation is desired.

N
The POWER SWITCH does not disable 120 AC or the
battery charger. To disconnect 120 Vac, remove the
fuses or disconnect 120 Vac from Terminal P2.
SCADA Operation
Remote monitoring and control operation are provided
through the SCADA terminals. The control is activated in
the REMOTE mode when the SCADA toggle switch is set
to REMOTE.
Features available through SCADA terminals:
●
●
Select one of several motors.
●
●
Read status of selected motor.
●
●
Operate the selected motor.
●
●
Monitor opening or closing action.
REMOTE Mode Features
All remote features are accessed through a terminal strip
mounted on the relay circuit board. (See Figures 6 and 8).
Remote operation is permitted only when the SCADA
switch is in the REMOTE position.
The operation of each feature is described as follows:
MOTOR SELECT CONTACTSe:
Dry contacts for SCADA
selection of a switch or interrupter mechanism for status
indication or operation. These contacts require a maintained
contact closure for as long as the status is being read or the
motor actuator is active.
If this contact is opened during an operation, the motor
actuator will stop immediately. If more than one motor is
selected simultaneously, the lowest numbered motor will
be selected by default.
STATUS CONTACTSe:
Dry contacts which indicate open
or closed status of the switch or interrupter mechanism
selected via the SCADA Motor Select Contacts.
CLOSE CONTACTe:
Dry contact which initiates closing the
switch or interrupter mechanism selected via the Motor
Select contacts. A momentary contact closure between
terminal 21 and terminal 22 on the SCADA terminal strip
is required.
OPEN CONTACTe:
Initiates opening the switch or
interrupter mechanism, selected via the Motor Select
contact. A momentary contact closure between terminal
19 and terminal 20 on the SCADA terminal strip is required.
CLOSING CONTACTe:
Dry contact which indicates that
the motor actuator is closing the switch or interrupter
mechanism selected via the Motor Select contacts. The
motor is closing when the contact is closed (terminals 1
and 2).
OPENING CONTACTe:
Dry contact which indicates that
the motor actuator is opening the switch or interrupter
mechanism selected via the Motor Select contacts. The
motor is opening when the contact is closed (terminals 3
and 4).
SCADA SWITCH POSITION CONTACTe:
A dry contact
which indicates the position of the SCADA switch. When
the SCADA switch is in the REMOTE position, this contact
will be closed. When the SCADA switch is in the LOCAL
position, this contact will be open (terminals 5 and 6).
