2. FEATURES
LAN Interface Connector
The Alpha 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:
2.5 Communication / Interface Options , continued
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.

5.13 Event Descriptions (Alarms) , continued
Blackout (BLACKOUT) - The blackout alarm is triggered when the input voltage
is lost for 12 ms, or when the RMS input voltage is less than 1/2 the nominal voltage
for 100 ms or longer. * *
Frequency High (FREQ_HI) - A frequency high alarm is triggered when there
is a power line problem where the input frequency increases beyond the preset limit.
* *
Frequency Low (FREQ_LO) - A frequency low alarm is triggered when there
is a power line problem where the input frequency decreases beyond the preset limit. * *
Output Voltage Low (VOLT_LO) - The output voltage low alarm indicates that
the output of the UPS is too heavily loaded, or there is a fault within the UPS. Reduce
the load connected to the UPS.
Output Voltage High (VOLT_HI) - The output voltage high alarm can be caused
by some equipment which draws power at irregular intervals. Disconnect all equipment
from the UPS and determine whether the fault will repeat. If it does, the unit may be
out of calibration, or there is an internal fault causing the overvoltage condition. Have
the unit serviced by an authorized Alpha Repair Depot.
Output Power Overload (PWR_OVLD) - The output power overload alarm
indicates a condition where the output of the UPS is too heavily loaded. If this is not
corrected, the unit may go into a shutdown condition to protect the UPS's internal
circuitry.
Output VA Overload (VA_OVLD) - The output VA overload alarm is triggered
when the RMS current exceeds the rating of the UPS. Reduce the load on the output
of the UPS to prevent overheating.
Output Over Voltage Fault (OVER_V_FLT) - The output overvoltage fault
alarm indicates a malfunction has been detected in the control circuit. The output
voltage has been shut off to protect the load from an overvoltage condition.
Output Short Circuit (SHORT_CCT) - The output short circuit alarm indicates
a load was connected to the UPS that was shorted. This could be caused by a
miswired AC power cord or equipment connected to the UPS that is in need of repair.
NOTE: This condition activates the SERVICE alarm, along with an audible
alarm which can be cleared by pressing the MUTE key.
Internal Temperature High (AMB_TEMP_HI) - The internal temperature high
alarm indicates that the temperature of the UPS, measured by internal circuitry, was
found to be too high. This could be caused by a sustained overload on the output of
the UPS, a blocked fan (if equipped), or operating the unit in an excessively high
ambient temperature. To prolong the life of the batteries and UPS components, determine
and correct the cause of the over-temperature condition.
5. RS-232 TERMINAL COMMUNICATION
* * Indicates events that cause the UPS to operate in “LINE FAILURE” mode.
