Operation and Troubleshooting
7.1 Operation
The battery voltage must be higher than 9 volts for the SPS to operate.
7.1.1 Setting the Battery Size and Type:
The battery selector switch located at
the right side of the chassis must be set according to the type and size of the battery
bank the SPS is connected to as shown in table II below.

If the bulk mode times-out the charging process will go to the float mode
immediately bypassing the acceptance mode.
7.1.2 Turning the SPS ON:
After correct installation, the built-in transfer relay
automatically switches the SPS to “external power” mode activating the battery charger
any time a proper external AC voltage source is present. Setting the charger current
draw to zero with the LCD Remote Control/Status Panel can turn off the battery charger.
See figure 2, item (4) page 8.
The “inverter mode” can only be activated when there is no proper voltage external AC
power source. The inverter is turned ON or OFF by the LCD Remote Control/Status
Panel. See figure 2, item (3) page 8. The inverter can be left ON and the SPS will
automatically cycle back and forth between the battery charger and inverter. However,
there is a one to two amps draw on the batteries when the inverter is ON and there are
no AC loads which could discharge the battery(s).
