Testing LED Array
WARNING! High Powered LED sources produce an extremely intense and
concentrated light source. Direct viewing of the LED should be avoided.
Testing of the LED array will require opening the lantern housing (see Section
4.3
Disassembly/Reassembly). Measure the voltage between LED+ and LED-
when the array is under power (see Figure 10 Internal Wiring Diagram). A
properly functioning LED string will measure 25 to 35 VDC, depending on LED
color. When no or very little voltage is measured, the power supply is
malfunctioning and it should be replaced. When 45 to 60 VDC is measured,
depending upon input voltage, then the LED string is open and the light should
be returned to the repair depot.
4.5.4 Troubleshooting with SignalView
™
SignalView™ monitors the Nova-65 SC and provides information that is helpful
in troubleshooting. The following sections describe check points that are read
and displayed by SignalView.
LEDs Enabled:
The control circuit checks conditions listed below to determine when the LED
array should flash. When any one of these items is true SignalView will indicate
that the
LEDs are not enabled:
Unit is set for low voltage cutoff and input voltage is too low
Sunswitch is in bright light or is defective (shorted)
Unit is set in software for main/standby and has an even address (is
in standby mode)
The real time clock is enabled and is currently signaling seasonal
shutdown mode.
Error Status Messages
SignalView monitors the Nova-65 SC and reports the following:
Low Voltage Cutoff
Indicates the battery voltage has dropped below the operator-set voltage level.
This condition asserts the “Fail” terminal.
Main Fail
Main/Standby option is selected, the Nova-65 SC has determined that the main
lantern has failed and the standby lantern is operating.
