5.9 User Parameters
“USER PARAMETERS” allows you to set the information for
automatic test, output voltage shutdown, display unit identification, and to
change the security codes. Whenever one of the USER PARAMETER
items is accessed, you are prompted for a security code. Note: The code
(1111) is preset at the factory and can be changed by entering the SET
USER SECURITY CODE screen (menu item 58).
Unsolicited Alarm Messages
The CFR can transmit alarm messages (in ASCII format) to notify a
status change or a power problem. Once this feature is enabled, alarm
messages are transmitted automatically on the RS-232 port as soon as the
status of the CFR changes. You can connect a terminal to the CFR to
monitor its status and log all power problems. Refer to menu items 56 and
509-511 for a detailed description.
Automatic Output Shutdown
The output of the CFR can be turned off by sending a command via
the RS-232 port using a computer or terminal. Refer to menu items 501-
508 a for detailed description (menu items 501-506 are intended for
scheduled shutdown even when the AC line is present; 507 and 508 items
can be used to switch the inverter ON and OFF to preserve the battery).
When the CFR receives a “Start Shutdown” command (menu item
502), it waits for the period that is specified in the “Output Shutdown Delay”
(menu item 505) and then shuts down its output. The CFR will remain in
the shutdown mode for the time specified in the
“Output Shutdown
Duration” (menu item 506). Depending upon the setting of the “Output
Shutdown Recovery Mode” (menu item 504) the CFR may restore output
power immediately, even if the input AC line is not present, or may wait for
the input AC line to be restored.
