blue. The blue light will flash rather fast when the UPS battery approaches a
fully discharged condition to remind the operator that power will soon finish.
In few seconds, the whole system will soon be automatically turned off and the
LED module will be OFF. In case the AC power resumes during the usage of
the battery power, the flashing LED will keep on flashing for few seconds
before steady till the AC supply is stable.
Power ON/OFF control
The FT-6315 system implements electronic power control, such that
the main power to the system may be controlled by many methods as below:
1. Hardware power switch
2. Software OFF command
3. Emergency power OFF
Switching from OFF to ON requires a normal supply of the AC power.
4. Automatic power ON control
Hardware Power Switch
This button is located at top front corner of right
side of base unit as in right picture and can be used to
turn the system on and off alternatively. This hardware
switch can also be programmed to be an ON only switch through software
command so that when this switch is accidentally pressed during system turned
on, the system just remains on and unaffected. When using this feature, please
make sure that the software application has the ability to power off the
machine. In preloaded Windows, “Posiflex Power Switch Manager” in
“Posiflex Tools” in the Program Files helps managing these functions.
There must always be at least 10 seconds waiting before switching on
again once the system is powered off successfully.
Software OFF Command
The system may also be shut down under software control. Please just
follow the arrangement by your system integrator for this capability. The FT
also provides a specific means for the software to detect if the system is
working on external or UPS battery power. Due to this feature, compatible
software applications have the ability to change operating conditions when
running on standard/backup power. The software programmer may take
reference from the FT technical manual to apply such features.
Emergency Power OFF
In case of serious system halt due to any reason, the system could fail
to be powered off through normal means. Press and hold the Power ON/OFF
Switch for Emergency Power Off. Release the switch after the system powered
off. It will take about 4 seconds if the hardware switch is set to “ON/OFF”
mode and it takes about 10 seconds if the hardware switch is set to “ON only”
