1) MESSAGE
The display shows a fault code, the description of the fault and a guidance of what action is to be taken
by the user. A maximum of 10 faults are displayed at one time. If an input power failure occurs during a
fault condition, the fault indication and input power failure announcement are alternatively displayed at 5
second intervals.
2)

EXTERNAL SIGNAL TERMINAL BLOCK
The UPS is equipped with terminals strips, TN1 (Input) and TN2 (Output), on the Auxiliary Connection
Board, IOAU-09 for external annunciation of alarms and for remote access of certain UPS functions.
Some of these terminals are user-assignable to a variety of functions. These can be programmed to:
•
Inputs (TN1): Control the UPS remotely, or report environmental data to the UPS.
•
Outputs (TN2): Report status data from the UPS to external annunciation/monitoring devices.
Adding a second external I/F PCB "IOAU-09" will double the number of signal outputs (applicable
for OUT1 to OUT8.)
4.4.1
Aux Contacts - Input
The UPS is equipped with a series of input/output terminals for external annunciation of alarms and for
remote access of certain UPS functions. The layout of terminals is shown in Section 4.4.1 and 4.4.2.
Figure 4-18 and Figure 4-19 with a functional description of the input/output port presented. OUT1 to
OUT8 are user programmable, but factory default settings are shown in Table 4–1.
Adding a second external I/F PCB "IOAU-09" will double the number of signal outputs (applicable for
OUT1 to OUT8.)
