Menu Commands Overview - Alpha Technologies CFR 600 Operator's Manual

5.4 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 5.12 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 param-
eters together. This command is discussed in section 5.11.
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 UPS-CFR switches to normal operation
when input line is restored. Note: This 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" may cancel a pending shutdown by sending command
"503".
