Programmable Signal Inputs

The UPS incorporates four programmable signal inputs: one RS 232 input, two connectivity card inputs,

and one RPO terminal input. See figure 21 on page 21 for the locations of the ports. Configure the

inputs with the "Signal Inputs" setting in "User Settings" on page 15.

The table 11 shows the programmable settings for the signal inputs. Table 12 shows the operation logic

for the signal inputs.

Table 11. Programmable Signal Inputs

Signal Description

Not Used The input operates only as a serial input (RxD) or has no function.

Force Bypass If active, the UPS is forced to static bypass operation regardless of the bypass

status.

Remote

Shutdown

If active, the UPS output turns off after a user-defined remote shutdown delay.

The batteries continue charging. Inactive input does not abort the shutdown

countdown and does not cause the UPS to start up automatically.

Delayed

Shutdown

(and restart)

If active, the UPS output turns off after a user-defined delayed shutdown delay.

The batteries continue charging. Inactive input does not abort the shutdown

countdown but will cause the UPS to start up automatically if the input voltage

exists.

On Generator If active, synchronization is disabled and the UPS transfers to bypass.

Building Alarm 1 If active, the UPS generates the "Building Alarm 1" alarm.
