Bypass Switch Modes

The maintenance bypass switch has three modes of operation: Normal Mode,

Bypass Mode, and Test Mode. It is configured as shown in Figure 9

Normal Mode

The NORMAL mode for the HC-DySC is the input circuit breaker (CBI) and

the output circuit breaker (CBO) closed. The bypass circuit breaker (CBB) must

be open or the HC-DySC will not be able to correct voltage sags. There is a red

indicator light on the enclosure that is lighted when the bypass circuit breaker is

closed. The green "OK" status box should be shown on the touchscreen display.

The green "OK" box indicates that the voltage at the output of the HC-DySC is

within the +10%, -13% normal window. Refer to Table 2 for operational

conditions and indications

Bypass Mode

The BYPASS mode for the HC-DySC is for the input circuit breaker (CBI) and

the output circuit breaker (CBO) to be open. The bypass circuit breaker (CBB)

must be closed to provide power to the load while the HC-DySC is being

serviced.

Refer to Maintenance Bypass Transfer Procedure

on page 18 for instructions on

transferring the system into and out of bypass mode.

WARNING: Servicing must only be performed by factory authorized and

qualified personnel
