While in Automatic Voltage Control Mode, the control will cycle through several
different status messages. The messages include the Total Operations counter, the
number of 24 hour Auto operations, the Line Voltage, the Present Time and either
the Delta Volts or any activated timer (i.e. the “Close Inhibit” timer, or the Manual
Open/Close maintenance timer).
If the control powers on into a high Line Voltage condition (> 130.0 volts) an IMME-
DIATE OPEN operation occurs, bypassing the OPERATION TIME DELAY time.
Automatic Time Operation
– Automatic Time Control Mode is active when the
front panel rotary switch position is set to AUTO and the Control Mode is set to
“Time”. The AUTO LED will also light. When Automatic Time Control Mode is active,
the control will open the capacitor bank when the control clock reaches the “Open”
set point and the control will close the capacitor bank when the control clock reaches
the “Close” set point, subject to the weekend settings. To adjust the set points for
automatic time operation, use the front panel rotary switches to select the
parameter. Please refer to Figure 5.
3) CLOSE TIME is the set point for closing the capacitor bank based upon the
control clock. To adjust this setting, the upper rotary switch must be set to
TIME FUNCTIONS and the lower rotary switch set to CLOSE TIME. Use the
Adjust switch to select the desired time.
4) OPEN TIME is the set point for opening the capacitor bank based upon the
control clock. To adjust this setting, the upper rotary switch must be set to
TIME FUNCTIONS and the lower rotary switch set to OPEN TIME. Use the
Adjust switch to select the desired time.
While in Automatic Time Control Mode, the control will cycle through several
different status messages. The messages include the Total Operation counter,
the number of 24 hour Auto operations and the present time.
Automatic Time Operation with Voltage Override Operation
– Automatic
Time with Voltage Override Control Mode is active when the front panel rotary
switch is set to Auto and the Control Mode is set to “Time/Volt”. The Auto LED will
also light. When this mode is active, the control will operate as described for
Automatic Time Operation as long as the sensed voltage is in the “non-Voltage
Control Range” (below the OPEN VOLT setting and above the CLOSE VOLT
setting). Automatic Voltage Override will occur when the sensed voltage crosses
either the OPEN VOLT or CLOSE VOLT setting with the following priority:
The OPEN VOLT setting has priority over the CLOSE VOLT setting, the CLOSE
TIME setting and the OPEN TIME setting.
The CLOSE VOLT setting has priority over the CLOSE TIME setting and the OPEN
TIME setting.
