Strong International XENON FXPS, Instruction Manual

TROUBLESHOOTING

 (continued)

Contactor does not energize (no audible “click”)

1. Line safety switch open.  Turn “ON.”

2. Console “Rectifier” circuit breaker off.  Turn “ON.”

3. Circuit breaker or fuse in AC line open.  Check AC source.

4. Lamphouse interlock switch open.  See lamphouse manual.

5. Faulty  contactor  coil  or loose connection at coil terminals.   Repair or replace.

Contactor pulls but lamphouse igniter does not fire

1. Faulty contactor contacts.  With coil energized, check for continuity across the contacts from the

“L” side to the “T” side; repair or replace if defective.

2. Insufficient DC output.  See INSTALLATION section; increase tap setting as required.

3. Faulty igniter.  See lamphouse manual.

4. Low open circuit voltage (less than 110 V.DC).

a) Check ceramic resistor R1; should be in circuit and measure 100 Ohms.

b) Check boost diodes CR7 and CR8.  See preceding DIODE TESTING section.

c) Check filter capacitors C1 and C2.  Replace if defective.

NOTE:   Lamphouse “Emergency  Ignite” switch (if present) will frequently overcome low open

circuit voltage condition, but will not permit normal autostrike function.

Bulb requires multiple ignition pulses to light

1. Insufficient DC output.   See INSTALLATION section; set tap setting as required.

2. Faulty K2 relay.  Replace if defective.

3. Faulty or expired xenon bulb.   Check for darkened  envelope, worn electrodes; replace if required.

4. One or more faulty bridge diodes.   See preceding DIODE TESTING section.

Bulb goes out during operation

1. Excessive heat at rectifier heat sinks; thermal switch S1 opening.   Check for free air flow,  blower(s)

operating  at  full speed.  Check for loose connection.

2. Faulty  lamphouse interlock switch (“Door,” “Air,” etc.).   See  lamphouse manual.

Excessive flicker in light output

1. Improper tap setting.   All taps must be on  same  numbered  or  lettered step.

2. Faulty bridge diode.  See preceding DIODE TESTING section.

3. Faulty xenon bulb.  Check for cracked or sagging electrode(s).

4. Open filter capacitor C1 or C2.  Replace if defective.

Bridge diodes (CR1-6) fail repeatedly

1. Insufficient air flow; defective blower.  Clean, repair, or replace as required.

2. Incorrect replacement diode.  Use only the specified rated diode(s).
