•The current which the control actually measures in mA, is displayed at FC 48.
•The control is designed for 200 mA as the rated CT secondary output current and will
meter to 800 mA with no loss of accuracy.
•To calibrate, this value is compared to a reference ammeter and, if different, is changed
to display the correct value.
•Note: A default calibration factor is programmed into non-volatile memory at the factory;
adjustments should not be necessary.
•See Section 8: Troubleshooting: Control calibration.
•In addition to the low and high limits, the user must enter a value that is within 5% of
the displayed value.

•This function code identifies the tap-changer type. Changing this function code changes
the control’s sampling rate to accommodate varying tap-changer types.
•Options include: Eaton's Cooper Power series QD8; Eaton's Cooper Power series QD5; Eaton's
Cooper Power series QD3; Eaton's Cooper Power series Spring Drive; Eaton's Cooper Power
series Direct Drive; Siemens; General Electric; Howard; LTC Reinhausen; ITB, Toshiba, User

Volts View Modify NA 120.0 100.0 135.0
•The set voltage is the voltage level to which the control will regulate on the 120 V or
240 V base during reverse power flow.
•See FC 1 and Section 6: Control Features: Reverse power operation.
•If an alternate configuration is active, the fourth LCD line displays which one is active,
e.g. (ALT CONFIG 1).
•If FC 148 Nominal Load Voltage is set to 240 Volts, limits are expanded (doubled).
•If FC 148 is set to System Line Voltage, this setting must be set in terms of the system
line voltage. For example, on a 7200 V system, with a desired set voltage 1% above the
nominal voltage, the setting would be 7272.
