Communication Interface
Dry Contacts
The remote contacts interface is a standard feature. It is provided
through solid state relays with contacts through a DB9 male
connector located on the back of the UPS (refer to the
Communication Option User Manual for a more detailed description
of this option).
RS-232C
RS-232C serial communication interface is a standard feature
provided through a DB9 female connector located on the backside of
the UPS (see “Electronics Module Layout “, page 9). This interface
allows communication between the UPS and a personal computer
(see the Communication Option User Manual for a list of the data
available from the UPS via the RS-232C communication link)
Option Card Slot
The option card slot is a standard feature. An optional network
adapter card slides into the slot which is located on the back of the
electronics module (figure 1, page 9). This optional interface all ows
the UPS to be monitored across the network or from any point on the
Internet (refer to the Communication Option User Manual for a more
detailed explanation of this option).
Troubleshooting
Warnings and Faults are those abnormal conditions that can occur
and could cause the unit to stop normal operation. These conditions
are detected by the protective circuitry in the unit. The UPS
“Warning/Fault” lamp will light red when a warning or fault occurs.
"Troubleshooting" involves monitoring the LED’s on the front pan el
and then interpreting the readout by using the warning and fault
mode display charts that follow. Only the state of the LED’s listed in
the chart should be considered. Other LED’s might be active;
nevertheless, only those listed under the column “LED state” should
be considered when diagnosing a warning, or fault.
Warning/Fault Modes
All warnings will cause the red “Warning/Fault” LED to flash. Al l
faults will cause the red “Warning/Fault” LED to light continuousl y.
Some warnings and most faults will cause the UPS to transfer to
bypass mode. In many cases, after the condition that caused the
fault is corrected the unit will automatically transfer back to norm al
mode. For those cases where the unit does not transfer back
automatically contact your Toshiba UPS service representative at 1-
877-867-8773 (outside the U.S. call 713-466-0277).
