3.8.1
Power supply recommendations
The Valueline IPC requires a 24 V DC power source. This can be either a standard power
supply or a DC UPS. The following table provides expected amperage requirements for
different configurations.
3.8.2
QUINT-DC-UPS… installation
When using the QUINT-DC-UPS… uninterruptable power supply, there are two ways to
connect it to the Valueline IPC depending upon the level of monitoring/control desired.
–
Power connector: This connection method allows monitoring of the
Bat.-Mode
signal
via two terminals labeled
A
and
B
on the power connector. When the uninterruptable
power supply switches to battery power, it closes a contact to activate the Bat.-Mode
signal. The operating system starts the “Minutes on battery before critical alarm” timer,
if it is configured by the user (see Figure 3-39). If it is not configured, the operating
system starts the Critical Alarm timer which gives 30 seconds to launch and execute an
optional program before the VL IPC initiates the shutdown procedure.
–
Serial port (DB-9): This connection method provides additional communication
between the Valueline IPC and the uninterruptable power supply.
–
As in the power connection method, when the un interruptible power supply
switches to battery power, it closes a contact to activate the
Bat.-Mode
signal. The
operating system starts the “Minutes on battery before critical alarm” timer, if it is
configured by the user (see Figure 3-39). If it is not configured, the operating
system starts the Critical Alarm timer which gives 30 seconds to launch and
execute an optional program before the VL IPC initiates the shutdown procedure.

Any program launched at this time is typically used to send an alert message to a system
administrator that the computer is shutting down. This program must reside in
C:\Windows\system32.
