to connect anywhere)
- connect cell_5 to position 5 on J6 header
- connect cell_4 to position 4 on J6 header
- connect cell_3 to position 3 on J6 header
- connect the battery's negative terminal(or GND) to position 2 on J6 header
Starting and Stopping with battery power….
If everything correctly configured pressing shortly the J8 button will turn on the output
and your UPS will be started, energy will be flowing from battery to the output.
Long pressing (5 sec) J8 button will initiate shut down of the UPS. A pulse is sent to
the motherboard than the UPS waits a predetermined UPS_HARDOFF_TOUT (60s by
default) before the output voltage is turned off.
The motherboard's state is sensed by measuring the output power via. If the
motherboard was shut down by the OS no pulse will be sent. The output power
thresholds can be set by setting the POU_LO and POUT_HI parameters. If the
motherboard consumes more than the POUT_HI threshold (meaning motherboard is
not shut down by OS) the pulse will be sent in case shutdown conditions are fulfilled.
Connecting DC input power….
Connect a proper input voltage source to the J1 connector.
If input voltage is present (configurable by thresholds), openUPS will enable the proper
power path and energy will be flowing from input to output and, if necessary, battery
charging is started. Each cell is carefully monitored so that in case of an under-voltage
or over-voltage event proper actions are taken.
Operating modes:
-Auto restart when Input Power is Present=YES
Output and charging is started once the input power is present.
-Auto restart when Input Power is Present=NO
Only charging is started once the input power is present. The output will be started
once the Start button is pressed.
Main LED blink modes:
1) 5 x (30ms ON,30ms OFF) quick blinks during 750ms period repeatedly: initial
delay
2) 500ms ON , 500ms OFF: UPS is in standby (waiting for proper starting
conditions).
The unit will stay in this state if one of the following conditions does not fulfill:
-Improper battery configuration
-Cell under-voltage and input voltage is not present
3) Steady ON: UPS is running from Input
4) 500msec ON, 2.5 sec OFF: UPS is running on Battery
5) 1 sec ON, 1 sec OFF: OFFDELAY (time between a shutdown condition fulfilled
and the off pulse is sent to the motherboard) set by the
UPS_VBAT_UVP_OFF_TOUT parameter.
