Maintenance and Troubleshooting FineLine 200PC User’s Manual
Low pressure error 1. Supply gas pressure(s) less than 150 psi.
2. Faulty pressure switch or associated wiring
inside gas console.
Pressure error during cut 1. Supply gas pressure(s) fluctuating during cut.
Chopper Test Procedure
Warning: Only qualified maintenance personnel should perform the
chopper test procedure. The system utilizes potentially fatal A.C. and
D.C. voltages. All maintenance should be performed with safety in
mind. Be aware that the large blue electrolytic capacitors on the
chopper assembly store large amounts of energy even after power has
been removed from the system. Wait at least five minutes after turning
off power, and then use a voltmeter to verify that the capacitors are fully
discharged before touching the chopper.
Note: A chopper troubleshooting flow chart can be found at the end of this
section
.
1. Turn off all power to the FineLine power supply.
2. Open the RHF console door and disconnect the black primary wires of the
high frequency transformer from the 120 VAC line filter. Close the RHF
console door to activate the door interlock switch.
3. Remove the front and left side panels from the power supply to expose the
output terminal block and the microprocessor p.c. board.
4. Remove the Electrode and Nozzle leads from the
bottom connections of the
output terminal block (refer to Figure 3-3).
5. Apply three phase power to the unit and check the primary power on the
input terminal block TB5 (refer to Figure 3-2).
6. Depress the ON button to energize the FineLine system, and then apply a
start signal to the unit. Note that the unit will only energize for
approximately two seconds each time a start signal is applied. When
making the following readings, be sure the red DC Power light is
illuminated on the front control panel of the unit
. After applying the start
signal, check the three phase voltage input to the chopper at the diode bridge
terminals (three right side screws on the chopper assembly) for 208 VAC. If
the voltage is not present, check for primary voltage on the main contactor
CON and on the primary side of the power transformer.
