The controller (CP) voltage and frequency setting can be displayed and changed from the keypad. See the table on the previous page. Some settings may require a password (if the controller is set up for one).

¡From any of the Status displays, press the Enter/Save Settings ￿ key to move to the Settings level of menus.

© Press the Enter/Save Settings ￿ key to move to the CP Settings display.

¢Then you can press the right arrow "key to see the other voltage and frequency displays (as shown below). An overview explanation of each setting is listed below.

5 Voltage & Frequency Menus (last menu loops back to first)

CP Settings

see page 2–1

This display shows the base configuration of the controller. These settings are hardware activated and cannot be changed from the keypad:

Nominal source voltage — Normal and Emergency sources Nominal source frequency — 50 or 60 Hz

Normal & Emergency source sensing — single or 3 phase Switch type — open, closed, or delayed transition

Normal Voltage

see page 2–1

This display shows pickup, dropout, and over–voltage trip settings for the Normal source. They are in percentage of nominal voltage and volts rms.

Normal Frequency

see page 2–1

This display shows pickup, dropout, and over–frequency trip settings for the Normal source. They are in percentage of nominal frequency and Hz.

Normal Voltage Unbalance

see page 2–1

This display appears only if the CP is set for 3 phase sensing on Normal. When enabled, the CP considers the Normal source unacceptable if the calculated voltage unbalance is greater than the specified dropout.

Emerg Voltage

see page 2–1

This display shows pickup, dropout, and over–voltage trip settings for the Emergency source. They are in percent of nominal voltage and volts rms.

Emerg Frequency

see page 2–1

This display shows pickup, dropout, and over–frequency trip settings for Emergency source. They are in percentage of nominal frequency and Hz.

Emerg Voltage Unbalance (not shown) see page 2–1

This display appears only if the CP is set for 3 phase sensing on Emergency. When enabled, the CP considers the Emergency source unacceptable if the calculated voltage unbalance is greater than the specified dropout.
