Emerson GXT2U user manual Pins 5 & 6 Any-Mode Shutdown, Auto-Enable Output Pin 6 Logic

Pins 5 & 6 - Any-Mode Shutdown

1.Pin 6 of the 9-pin communication connector is used for “Any-Mode Shut- down” of the UPS output. This control input may be used in special applica- tions to disable the UPS output power—both Inverter and Bypass.

2.The Options tab allows the behavior of the Any-Mode Shutdown feature to be modified. When the program opens, or the REFRESH button is pressed, the UPS setting is read by the configuration program and displayed.

Auto-Enable Output

! WARNING

Note that when this option is selected and the UPS output is disabled using Pin 6, the UPS output can turn on automatically and without warning if the Pin 6 connection is changed.

Pin 6 Logic

! WARNING

DO NOT CHANGE THIS OPTION from the factory default setting unless you are ready to install a normally-closed connection between Pins 5 & 6. This connection must be maintained to use the UPS or to use the configuration program again, including the ability to change the UPS setting back to the default setting using the configuration program via a serial communication link.

If version 1.6 (or later) is used with an earlier Liebert GXT2U model (with an earlier UPS firmware version), the Any-Mode Shutdown features cannot be changed.

If the configuration program is used with an earlier UPS model (with an earlier UPS firmware version) that does not support the modification of these settings, the Options tab will display a reminder of the factory default settings. These cannot be changed.
