Status Indicators
REMOTE/AUTO LED
The (red) LED will remain illuminated whenever the
control is selected to automatic operation.
LOCAL MANUAL LED
The (yellow) LED will illuminate when Manual mode
has been selected using the front panel Remote/
Auto, Local Manual Switch.
ALARM LED
The (red) LED will illuminate when any of the
Programmable ALARM Functions set the output
relay to true.
CLOSE LED
The (red) LED will remain illuminated when the
capacitor bank switch is closed. The LED will flash
any time the control is timing to perform a Close
operation.
When in Manual, if a Close operation is initiated
while the control is in the Re-Close delay, the Close
LED will flash until the operation is completed.
OPEN LED
The (green) LED will illuminate to indicate when the
capacitor bank switch is open. The LED will flash
any time the control is timing to perform an Open
operation.
OK LED
The (green) LED will remain illuminated whenever
power is applied to the unit and the watchdog circuit
indicates the microcontroller is functioning properly.
RSSI LED
When the (red) LED is illuminated, it indicates
that communications have been established with
the client. Depending on the wireless modem that
is installed, RSSI may also indicate the Receive
Signal Strength.
NEUTRAL UNBALANCE light (yellow) illuminates
when the control detects a neutral unbalance
current. This is indicative of failed capacitors or failed
switch closures on the capacitor bank.
Control Switches
REMOTE/AUTO, LOCAL MANUAL Switch
The REMOTE/AUTO, LOCAL MANUAL switch
selects the desired mode of operation from the
control front panel. When selected to "LOCAL
MANUAL" no automatic operation is permitted and
the O/C (Open/Close) switch is functional. In the
"REMOTE/AUTO" mode the control considers all
settings and operates the capacitor bank as required.
OPEN/CLOSE Switch
The OPEN/CLOSE switch allows Manual Local
control of the capacitor bank subject to the Timed
Function settings.
VOLTAGE SOURCE
▲
CAUTION: Do not reverse the ground and hot
wires when connecting an external source. A U
L
®
recognized replaceable fuse, 3 A, 250 V ac, 3 AG
fuse is installed to protect the control from damage
if these connections are accidentally reversed.
The Voltage Source switch position determines what
input (or none) is used to provide to the control and
energize the Capacitor Bank Switches.
• The "INT" position allows voltage applied
to the terminal block on the rear of the unit
to power the control and Capacitor Bank
Switches. This is the nominal position of
the switch
• The "EXT" position allows voltage
applied to the front panel binding posts
labeled "External Power" and "GND"
to power the control and energize
the Capacitor Bank Switches when
needed. This position is used for testing
purposes only and is typically used for
control bench testing.
• The "OFF" position removes all sources
of AC power to the control. This position is
used by some utilities as an extra method
of ensuring that the control cannot operate
the Capacitor Bank Switches during
maintenance, switching etc.
