Chapter 5. Troubleshooting

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.

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.
