2.12.2 Power-up
Test
When the controller is connected to DC power (either PV or battery), a diagnostic power-up test is
performed (refer to Figure 2-30). This power-up test takes approximately 12 seconds to complete
and veri
fi
es that all of the front panel LED’s and the display come on and stay on until the test is
complete. During this power-up test, the internal beeper is heard three times, each segment of the
3-character digital display turns on, and all nine LED indicators come on and stay on in sequence.
Right before the power-up test ends, the display shows the controller’s internal software version
(e.g., 1.10) and then the nominal battery voltage that was detected (i.e., 12, 24 or 48 volts)
1
.
When the power-up test has
fi
nished, the display should begin auto-scrolling thru the operational
screens. If the power-up test did not perform correctly or a fault occurs (F## code displays), refer
to Section 5.0, “Maintenance and Troubleshooting” for diagnostic help.
Note 1:
The system voltage switches are set to AUTO (default) from the factory. If the battery voltage is well
below the nominal battery voltage and the voltage that was displayed (i.e., 12, 24 or 48 volts) is incorrect
for your battery bank, change DIP switches 3 and 4 to the correct nominal voltage setting (see Section 3.1)
and re-power/re-boot the PT-100 to allow the new DIP switch setting to take effect.
