Enabling External Modem
All CFRs are shipped with the modem feature disabled. The following
configuration is performed using a computer with terminal emulation program to
access the RS–232 menus. See sections “2.6 RS–232 Communication Options,”
and “5. Terminal Operation” for details. The modem configuration screen is displayed
in menu 52 (see Fig 18):

To enable Automatic Alarm notification, use a terminal to make the following
changes under menu 52:
•
Set “Enable Automatic Alarms” to YES.
•
Set the monitoring station’s phone number in “Dial1.”
•
Set “Custom Init Cmd” if you are not using a USRobotics Sportster. (See
“Configuring the modem to work with CFR” following)
•
Ensure “Unsolicited Alarms” are disabled (See RS–232 menu command “509” in
section “5.9 User Parameters”).
If you have more than one CFR UPS, Alpha also recommends you set the
“Location ID” to a unique, descriptive string. Additional settings are available to
control which alarms are reported, which of the two numbers they are sent to, and
other options. See section “4.3. External Modem Operation.”
To allow dial-in, Remote Access, use a terminal to make the following changes:
•
Set “Enable Remote Access” to YES.
•
Set “Custom Init Cmd” if you are not using a USRobotics Sportster. (See
“Configuring the modem to work with CFR” following)

Menu Commands Overview
Overview
The following section provide a general overview of the menu structure and
give some examples of how to perform certain command functions such as testing
the UPS.
Querying CFR Status and Measured Parameters
The current status (mode of operation) of the CFR and all active alarms
are displayed at the end of the opening menu (see section 5.13 for a list of status
messages and alarm events). Press “ENTER” to query CFR status and alarms.
Use commands “1” to “4” to query the battery temperature, input (line) parameters,
output (load) parameters, and battery parameters. Command “0” is a special
command which displays all of the UPS parameters together. This command is
discussed in section 5.12.
Testing the CFR
Use commands “11” and “12” to start and terminate a self-test. During a
self-test, the UPS switches to the inverter mode to test the battery and the inverter
hardware. The test takes about one minute and, when complete an ASCII message
is sent to indicate the result. You may also schedule a self-test using commands
“53” to “55”.
Shutting OFF the Inverter to Save Battery
Commands “507” and “508” can be used when the UPS is in the inverter
mode to switch the inverter OFF to prevent a deep battery discharge during
extended line failures. The CFR UPS switches to normal operation when input line
is restored.
NOTE: Invoking the “507” or “508” command will drop the connected load.
Scheduling Output Shutdown/Reboot
The output of the UPS can be turned OFF by sending a RS-232 command.
Commands “501” to “506” control the output shutdown feature. When the UPS
receives a start shutdown command, “502”, it waits for the period specified in
output shutdown delay, “505”, and then turns OFF the UPS output. The UPS
remains in the shutdown mode for the mandatory down time specified by output
shutdown duration, “506”. Depending upon the setting of the output shutdown
recovery mode, “504”, the output is switched ON when the shutdown duration
expires or when the input is restored. You start a shutdown whenever the shutdown
delay is set using command “501.” A pending shutdown may be cancelled by sending
command “503”.
