Chapter 5. Troubleshooting
Basic Checks
Check that input power is connected properly. Actual line voltage must be within 10%
of the voltage rating shown on the equipment label. Labels are located on the rear of
the power supply. If the input voltage does not match, contact Fusion UV Systems.
DANGER: High Voltage -- Use extreme caution at all times when
troubleshooting the power supply. Line voltages are present even
when the lamp control switch is set to STANDBY.
Do not measure any voltages not specified in the troubleshooting
procedures: dangerously high voltages exist in the power supply.
Do not touch power supply/irradiator cable connectors while the
system is on. High voltages are present in the connector.
Do not touch any power supply components or wiring while the unit
is operating.
To troubleshoot the power supply, first turn off and disconnect all
power to the unit. All high voltage capacitors have an internal
discharge resistor which should discharge to a safe level in five
seconds. Physically shorting the capacitor terminals with an
insulated screwdriver blade is advised as an additional safety
measure.
DANGER: Ultraviolet Radiation -- Do not
test the irradiator without using adequate
ultraviolet light shielding and never look
directly at the UV lamp. Severe ultraviolet
burning of the skin and eyes can result
without proper safeguards.
