to last for more than few minutes, it is advisable to turn off the system instead of using
the battery up while repeatedly using it up reduces the battery life dramatically.
The battery will undergo self-discharging over time even when not in use. A
useful advice to preserve the battery at best condition is to regularly recharge the
battery if the battery or the TP system with the battery is put in storage for a period of
time. It is recommended to turn on the system to recharge the battery for 1 ~ 2 hours
every 3 months of storage if the storage temperature is lower than 30°C. The battery
should be recharged for 1 ~ 2 hours every month if the storage temperature exceeds
30°C. However, the user shall avoid the situation with storage temperature over 30°C
to protect the life of the battery. Do not connect any other battery to this UPS battery
because mixed use of batteries of different capacity, history, or manufacturers may
cause damages. In case the user wants to have a longer battery support time during AC
power off, he/she should consult his/her dealer for application of an external 12 V
battery.
UPS FUNCTION ENABLING
The complete UPS function requires use of the optional UPS battery. The
Posiflex UPS functions can support the system against intermittent power failure.
However, in order to achieve best hardware stability against any possible memory or
CMOS data loss or even system crash, the UPS function should be enabled or disabled
depending on the existence of UPS battery. This setup is based on the consideration that
when UPS battery is present and ready to serve, the UPS function should be enabled so
that the hardware power good signal will be maintained for a smooth power transition
to UPS battery power. On the other hand, when there is no UPS battery, the UPS
function must be disabled so that the hardware power good signal will be shut down
early enough to inhibit any improper operation of any device.
This setup on UPS function is in fact automatically taken care of with the
Posiflex software installed in the preloaded operating system of Windows. However,
just incase the application programmer wants to manipulate this setting or if the
operating system used is some one else, this setting can be achieved by sending
following command string to COM1 port under protocol: 9600 bps, parity none, 8 data
bits, 1 stop bit.
