ROHS (European) Option (E Option)
IP67 (Waterproof Tested) Option (Y Option)
Troubleshooting
Consistent with military standards, this unit is normally manufactured using lead based solder.
However, this unit can be built to ROHS lead free standards, identified internally by a red
colored printed circuit board by adding the E option. This is a no charge option, but can add 2-4
weeks to the delivery of an order.
This is the same unit as the VHC10W, except each unit is individually tested to comply with
the IP67 rating of withstanding 1 meter immersion for 30 minutes with no ingress of moisture.
This unit provides LED indicators to help diagnose any problems.
CHARGING
Indicates that the battery charger is charging the batteries:
If the LED is not on, the batteries may be fully charged and the charger is
supplying a float voltage to the batteries to keep them fully charged.
INPUT POWER
Indicates that power is being received by the unit
If the LED is not on, check with a voltmeter that there is power at the
connections.
Check that the polarity is correct, Positive to Pin 1 and Negative to Pin 2.
If the power is reversed, the unit is not damaged, but the input fuse
must be replaced by a service technician experienced in Surface Mount
Technology.
