2. FEATURES
LAN Interface Connector
The Alpha CFR-UPS provides a LAN interface port on a DE-9 female connector.
This port may be used to monitor the status of the UPS and shutdown the output
using basic UPS monitoring and shutdown software.
Two dry contacts are provided to indicate LINE FAIL and LOW BATTERY status
information. The port also accepts a dry contact input or an RS-232 level input to
shutdown the UPS output. The shutdown delay, duration, and recovery modes can
be configured using the RS-232 ASCII terminal commands (see section 5 “RS-232
Terminal Communication”). This port has the following pin out:

Using basic UPS monitoring software you can monitor and shutdown the CFR
through this port. In network applications, your UPS monitoring software can perform
an orderly shutdown on the network. Basic UPS monitoring software is provided as
part of many operating systems and can also be purchased from third party vendors.
Alpha Technologies “AlphaNet C shutdown software” can also operate in the basic
mode to shutdown the CFR before its battery reserve is exhausted. Refer to
AlphaNet C Shutdown Software User’s Manual or contact Alpha Technologies for
more information.

5.12 Event Descriptions, continued
Input Line Fail - Indicates that the UPS switched to backup power to protect the
equipment for one (or more) of the above conditions. * *
Normal Line Mode - Indicates that the UPS is drawing power from the AC line
and charging the batteries.
Test Mode - Indicates the UPS was put into a test mode condition either by the
TEST SCHEDULE routine or by pressing the TEST button on the Intelligent Interface
Device's panel. The unit will switch to backup power while in the test mode. * *
Float Charge Mode - This is the normal operating mode of the battery charger.
During LINE PRESENT operation, the batteries constantly receive a "Float" charge
voltage to ensure that backup power is available when required.
Service Codes (1-6) - These codes indicate a potential fault within the UPS. Call
Alpha Customer Support and report any displayed Service Codes. Also refer to the
Troubleshooting section (6.7) of the manual.
Serv Code 1 - Phase Lock Loop Failure. The phase lock loop circuitry has failed
to lock onto the AC input LINE due to instability of the frequency. If the UPS is
operating from a generator, check the frequency and adjust it if necessary.
Serv Code 2 - Micro software reset. The internal “watch dog” circuit has detected
a fault and reset the software. Contact Alpha to help determine the cause of the fault.
Serv Code 3 - Micro hardware reset. A micro hardware reset is activated as part
of the power on condition. If this alarm occurs during normal operation, it may indicate
a malfunction in the hardware circuitry. Contact Alpha to help determine the cause of
the fault.
Serv Code 4 - Power board EEPROM fault. The EEPROM on the power board
contains the unit configuration information. If this fault occurs, it signifies either the
configuration information has been corrupted, the EEPROM has malfunctioned, or there
is a loose connection inside the UPS.
Serv Code 5 - Power board hardware fault. The control circuitry on the power
board has detected a hardware fault condition which impedes correct operation of the
UPS.
Serv Code 6 - Neg DC supply rail fail. The negative voltage power supply to the
microcontroller has malfunctioned.
EMGNCY POFF - Emergency power shutdown.
OUTV SHTDWN - See menu 505 & 506 (see section 5.9).
* * Indicates events that cause the UPS to operate in “LINE FAILURE” mode.
