  • Page 14: Operation

    OPERATION The following settings and features are common to all control modes: Time Delay – Sets the operation time delay period. Using the Adjust switch, select the desired time delay, in seconds, from 3 to 600. This will delay both Open and Close operations in both Manual and Automatic operation mode by the time selected.
  • Page 15: Led Indicators

    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.
  • Page 16: Automatic Operations

    WARNING: The Control will revert to Automatic operation after 10 minutes following a Manual Maintenance Operation. The control will then automatically Open or Close the capacitor bank based upon the Automatic Operation programmed settings.

  • Page 17 Volts. Similarly, if the next open operation would cause the control voltage to be below the close voltage set point, the operation is not performed until the voltage rises above the close voltage set point plus Delta Volts. Upon power on, Delta Volts is preset to 0.5 volts.
  • Page 18 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).
  • Page 19 Automatic Temperature Operation – Automatic Temperature Control Mode is active for the NoMAX 900 ® when the Control Mode is set to “Temp. Only” and the rotary switch position is set to AUTO. The AUTO LED will also light. When Automatic Temperature Control Mode is active, the control tests the ambient temperature against the programmed OPEN TEMP and CLOSE TEMP settings.
  • Page 20: Specifications

    Automatic Temperature With Voltage Override Operation Automatic Temperature with Voltage Override Control Mode is active for the NoMax ® 900 when the Control Mode is set to “Temp/Volt” and the rotary switch position is set to AUTO. The AUTO LED will also light. When this mode is active, the control will operate as described for Automatic Temperature Operation as long as the sensed voltage is in the “non-Voltage Control Range”...
