Operation

3.2.8Load Transfer Procedures Screen

Go to the SCC Master Menu and move the highlighted cursor to LOAD TRANSFER PROCE- DURES. Note that this screen is displayed at the System Control Cabinet but is not required at the UPS modules. Press the Select pad and the Load Transfer Procedures screen is displayed.

The Load Transfer Procedures screen contains instructions to transfer the critical load between the UPS system and the bypass line. Comparisons of the UPS and bypass voltage, frequency and phase synchronization are displayed along with transfer status messages and an indication of circuit breaker overlap time. The metered parameter values on the Load Transfer Procedures screen are updated at half-second intervals.

Refer to 3.4.3 - Load Transfer Procedures for more details.

Item 1 - Voltage Comparisons: This chart shows the UPS and bypass voltage and frequency com- parisons between each of the three phases. If the UPS and bypass voltages are not within specified tolerances, a manual transfer is not permitted and TRANSFER PROHIBIT is highlighted.

The Voltage Adjust knob (push-to-turn), located on the SCC Operator Control Panel (Figure 10), is used to adjust the UPS output voltage (1 - 5 volts) above the bypass voltage. When the UPS and bypass voltages are within the specific tolerance, a manual transfer is possible and OK TO TRANS- FER is highlighted.

! CAUTION

The UPS output voltage responds very slowly to inputs from the Voltage Adjust knob. Make small adjustments and wait several seconds each time for voltage to stabilize before continuing.

Item 2 - Synchronization: This display shows the phase synchronization between the UPS output and bypass power. If the phase displacement is outside of the tolerance, a manual transfer is not per- mitted and TRANSFER PROHIBIT is highlighted.

During normal operation, the synchronization display should read UPS LEAD from zero to 4 degrees.

Item 3 - Status Messages: Three messages are constantly displayed here. Only the active message is highlighted. If TRANSFER PROHIBIT is highlighted, manual transfers/retransfers cannot be performed and automatic retransfers will not be initiated.

Item 4 - Manual Transfer Instructions: These instructions assist the operator in transferring the critical load between the UPS system and the bypass line.

If the load is on the bypass line, step 2 on the screen will instruct you to press the UPS and Control Enable buttons to retransfer the load from the bypass line to the UPS system.
