7.2.1.4
SETUP > SYSTEM > SYSTEM TYPE
Model type:
Indicate the maximum output power of your system. Here, assume no redundant modules, so
that all modules are considered when calculating the maximum potential system output..
Multi-system mode:
Indicate that the UPS will be operating in parallel configuration (multi-system mode).
A password may be required to modify this setting. If you do not have the appropriate password,
contact your distributor or sales agent.
7.2.1.5
SETUP > SYSTEM > SHUTDOWN AND AUTORESTART
Use this option to specify the behaviour of the UPS during a failure of the ac mains power.
•
You can set a specific limit to the duration of battery mode, after which time the UPS will
automatically turn itself off.
•
You can instruct the UPS to continue to supply backup power until the battery voltage descends to
the predefined level at which the UPS will turn itself off.
In this screen, you also specify if the UPS should automatically turn itself back on when the ac mains power
returns following a power failure, or if it should remain off.
7.2.1.6
SETUP > SYSTEM > CONTROLLER
This submenu contains functions related to the system controller.
7.2.1.6.1
I
NTERNAL ADAPTOR STATUS
For use by technician. Displays the data being passed to and from the adaptor card, PC710A, part of the
controller module.
7.2.1.6.2
C
ONTROLLER BATTERY
This option displays a submenu with functions related to the controller’s own internal battery.
Use this submenu to:
•
Define the time interval between automatic tests of the controller battery.
Default value is one week.
•
Enable/disable automatic testing of the controller battery. (“Enable” is recommended for most
circumstances.)
•
Start a test of the controller battery manually. This function can be performed at any time.
7.2.1.6.3

SHUTDOWN
(“
WATCHDOG FUNCTION
”)
Enables / disables the controller self-shutdown function, also known as the watchdog function.
“Enable” is recommended for most circumstances. Additional information on the watchdog function is
provided below.
Note: disabling the controller self-shutdown function (watchdog function) also disables the “UPS
OFF” button on the left side of the upper front panel of the UPS, described in section 4.2.1.
If the self-shutdown function is disabled
and
the LCD display screen happens to become disabled, the
question of how to switch off the UPS becomes a problem.
7.2.1.6.3.1 Watchdog function – general explanation
The watchdog function (performed by PC710A, the adaptor card) comes into play in the rare instance that a
problem occurs with communication between PC710A and the controller’s computer. The watchdog’s
purpose is to evaluate the symptoms of the problem and to try to recover normal communication between
PC710A and the controller’s computer.
If the watchdog ultimately fails to recover normal operation of the controller computer, the UPS continues to
operate, although with reduced functionality. Basic ON/OFF capability is still available as described in
section
