LED INDICATORS
Auto
– Indicates the Control is in Automatic mode and is using the operator
settings to control the Capacitor Bank state.
Operation Pending
– Flashes to warn the operator an operation is about to occur.
In Automatic mode, the LCD displays the type of operation about to occur (i.e.
Close or Open), and the amount of time before it occurs. The OPERATION TIME
DELAY setting determines OPERATION PENDING period.
Close
– When flashing, the CLOSE LED indicates the Close Motor Relay
is energized. When solid, the CLOSE LED indicates the Capacitor Bank is
connected to the line.
Open
– When flashing, the OPEN LED indicates the Open Motor Relay is
energized. When solid, the OPEN LED indicates the Capacitor Bank is NOT
connected to the line.
Note:
Both OPEN and CLOSE LEDs off indicates the Control has recently powered
on and the Line Voltage is within the Open and Close settings. There is not a
preferred Capacitor Bank state on the NoMAX
®
900; the operator settings and
Manual operations control the Capacitor Bank state.
Manual Bank Control
– The MANUAL OPEN and MANUAL CLOSE toggle switch
is used to “Manually” Open or Close the Capacitor Bank. To manually CLOSE or
OPEN the capacitor bank:
Switch the control out of the AUTO mode, verify the red LED is off, and
select TIME DELAY. Using the ADJUST switch, select the desired time delay,
in seconds, from 3 to 600.
Use the toggle switch to OPEN or CLOSE the capacitor bank. The OPERATION
PENDING LED will flash for the duration of the selected time delay. The CLOSE or
OPEN LED will flash during the time the output is energized and will remain on.
Note 1:
Pending manual operations can be cancelled by turning the control to AUTO.
Note 2:
The capacitor bank cannot be closed within less than 5 minutes from the
previous open operation to allow discharge of the capacitor bank. See
Five Minute Close Inhibit section, page 12.
Note 3:
Manual operations are counted by the operations counter (close operations
only), but manual operations do not count against the preset daily limit set
by 24Hr Auto Ops. See Automatic Operation section, page 14.
Manual Maintenance Operation
– When the rotary switch is in the AUTO posi-
tion, a Manual Open or Close is considered a maintenance operation. The Manual
operation completes and the Control suspends its Automatic testing for ten min-
utes. At the end of ten minutes, the Control reverts to Automatic operation and will
automatically Open or Close the capacitor bank based upon the Automatic
Operation programmed settings. While in AUTO, the amount of time remaining
before Automatic testing resumes is cycled on the LCD.
