System Status Messages

The system status messages indicate whether the static bypass switch is connected or disconnected, through the manually operated Static Switch Disconnects (see Figure 9). The status messages also advise the operator when a transfer or retransfer between the UPS system and bypass line is permitted, based on matching voltage, fre- quency, and phase.

The following status messages may appear in the system status area.

1.Static Switch Connected. The static switch is connected (the disconnect switches are closed—ON) and is ready provide a current path from the bypass input to the load.

2.Static Switch Disconnected. The static switch is disconnected (the disconnect switches are open—OFF) for maintenance procedures.

3.OK to Transfer. The UPS system voltage, frequency, and phase match the bypass line. This means that a transfer between the bypass line and the UPS system is permitted.

4.Not OK to Transfer. Either the UPS or bypass voltage, frequency, or phase is not within the specified limits or the static bypass switch is not available. Therefore, manually initiated transfer between the bypass line and the UPS system is not permitted. Emergency or overload transfer to bypass may still be available provided the “static switch unable” alarm is not indicating.

Load Block Messages

Status messages in the Load block indicate how many modules are in the system, how many modules are ON LINE, and whether the system is operating in the redundant mode.

The following status messages may appear in the load block.

1.N OF X MODULES CONNECTED. The number N is the number of UPS modules ON LINE. This means the module output circuit breaker is closed. X is the number of UPS modules in the system (connected to this SCC). This number is set from the System Configuration screen.

2.REDUNDANT. The capacity of the UPS modules ON LINE is sufficient to supply the critical load even if one module is taken OFF LINE. The critical load will remain on the UPS system if one module goes OFF LINE.

3.NON-REDUNDANT.The critical load will be transferred to bypass if one module goes OFF LINE, and you must transfer the load to bypass in order to perform maintenance on any UPS module.

4.TIME TO OVERLOAD TRANSFER. During an overload condition, the time remaining before transfer (in seconds) is displayed at the bottom of the load block. At each Module (MMU), the message is Time to Overload Shutdown.
