Sensor Adjustments

Voltage and frequency sensor pickup and dropout points are set to customer specifications (if none specified, standard factory settings are used). To change a setting, follow procedure on page 4–2. Use Tables 4-2 and 4–3 for settings and corresponding DIP switch actuators.

Table 4-2. Voltage and Frequency Settings. (

NOTICE

Any change in these settings may affect the normal operation of the automatic transfer switch. This change could allow the load circuits to remain connected to a low voltage source.

Shaded DIP switches are standard factory settings).
