6.12 Lift Start Test
1. Disconnect primary power at the source. Make
sure the MAIN CIRCUIT BREAKER is in the OFF
position.
2. Measure the continuity between the front panel
NEGATIVE (-) OUTPUT TERMINAL to CN5-3 on
the Main Circuit Board (PCB1), and from the front
panel POSITIVE (+) OUTPUT TERMINAL to CN5-1
on the Main Circuit Board (PCB1). Both should be
zero Ohms. Replace wire if continuity is broken.
3. Reapply power to the unit by turning the MAIN
CIRCUIT BREAKER to the ON position.
4. Disconnect connectors CN8 and CN9 on the
Main Circuit Board (PCB1). Measure the voltage
between CN22-5 and CN22-4 for 0VDC. Install a
jumper between the POSITIVE (+) and NEGATIVE
(-) OUTPUT TERMINALS on the front panel. The
voltage between CN22-5 and CN22-4 should
increase to +5VDC.
If the voltage does not increase in step 4 above, replace
the Main Circuit Board (PCB1).
6.13 Gas Control Test
Disconnect the remote control device from the REMOTE
8 receptacle.
1. Measure for +24VDC between pins 3 and 4 on
CN2 on the Main Circuit Board (PCB1). Replace
the Main Circuit Board (PCB1) if the voltage is low
or not present.
2. Measure for +24VDC between CN7-1 and CN7-2.
If no voltage is present, check and replace wires
between CN7-1 (PCB4) and CN4-1 (PCB2) or
between CN7-2 (PCB4) and CN4-2 (PCB2).
With a remote control device connected to the REMOTE
8 receptacle and contact closure between pins 2 and
3, measure the voltage between the gas solenoid valve
terminals. If the voltage is 24VDC and the solenoid does
not operate, replace the solenoid valve. If the voltage is
low or not present, replace the Main Circuit Board (PCB1).
There is a 150ms delay built into the circuit before the
voltage will be there.
6.14 High Frequency Test
1. Place the PROCESS SELECTOR Switch in the
STICK position.
2. Jumper pins 1 and 5 on the CN7 plug. Apply power
to the unit.
3. If the high frequency buzz is heard coming from
the HF Unit, the Main Circuit Board (PCB1) should
be replaced. If no sound is heard coming from the
HF Unit, the HF Unit should be replaced.
