Halaman Cetak5.8. Converter relies on conduction of heat to ambient air. An unpainted metal
surface of 36sq.in. and unobstructed air flow is required for maximum output.
5.9. Enable the converter by engaging the Ignition Key Switch. Using a voltmeter,
check and confirm output voltage from Converter High Power Output Channel
is 13.0Vdc +/-0.5V and that the polarity of the output is correct. Connect
electrical loads and verify operation of these loads.
5.10. If 'UNSWITCHED' operation is desired – meaning that the output of the
Converter is always energized (ON), permanently short the White Ignition
Wire to the Blue Input Battery Positive Connected Wire.
5.11. Some models supply a Dual Output Function where one output is continuous
enabled while a second output is switched. Load power is shared between both
outputs such that each output can produce up to the maximum rating of the
converter, as long as the TOTAL output power does not exceed the maximum
rating.
6. OPERATION
6.1. Input Ignition Key:
6.1.1. A SPST Switch serves as an ignition key. When the Key is in the 'ON' or
shorting position, the Converter output is energized (ON). When the Key
is in the 'OFF' or open position or left floating (un-terminated), the output
is de-energized (OFF).
6.1.2. The ignition key is a SPST type switch that connects the White Ignition
Key Input Wire to the Blue Input Battery Positive Wire. Alternately, if the
intent is to operate the Converter continuously without switching the
Converter Output, the White Ignition Key Input Wire should be shorted or
permanently connected to the Blue Input Battery Positive Wire.
6.2. When referring to Wiring Diagram Drawings:
6.2.1. 'B+' and 'B-' are Battery Positive and Negative inputs, respectively.
6.2.2. 'Enable' is also synonymous with 'Input Ignition Key'. This input, when
pulled to 'B+', activates the 'Switched Output'.
7. TROUBLESHOOTING GUIDE
7.1. Converter has no accessible user serviceable parts due to environmental sealing.
7.2. If electrical loads are not operating:
•
Check that the load is functional and not defective
•
Check all fusing, check for blown or open fuses
•
Check wiring for breaks
•
Check all Connectors, Wire Terminating Terminals, and/or Wire-Nuts for clean
connections, void of all corrosion
•
Check all interconnect wiring points such as crimps
