DISASSEMBLY
12) Reinstall the Main Power switch into the cabinet assembly using the two (2) screws that were
removed from the bracket during disassembly.
13) Reconnect the Power Switch cable connected to P801 to the power supply connector P810.
Connect the AC input cable socket wire leads to connector P802 of the power switch.
14) Use the nylon cable ties to secure all loose wiring. Inspect wiring for any pinched or damage
insulation and repair or replace if necessary.
This process completes the installation of the panel. The unit is ready to have AC power applied to the
set. The power supply Vs and Va run voltages must be checked and adjusted to the panel specifications.
The correct voltage settings are notated on an adhesive label placed on the backside of the panel.
VS AND VA VOLTAGE ADJUSTMENT
1) Apply power to the unit and turn it on. If the unit does not operate correctly, check all connections
and look for loose wires that may have been missed or that have become disconnected during the
reassembly process.
2) Allow the unit to run for 5 minutes. This is to allow the set to achieve operating temperature
before checking the Vs and Va run voltages. This step should be completed before making adjustments
to Vs and Va voltages.
3) Connect the positive ( + ) terminal lead of the digital multimeter to the Va pin of connector P805
and connect the negative ( - ) terminal lead of the digital multimeter to the ground ( GND ) pin of
P805.
4) Adjust variable resistor VR351 to match the Va
voltage specification shown on the label attached
to the panel. ( Deviation: ±0.5v )
5) Connect the positive ( + ) terminal lead of the digital
multimeter to the Vs pin of connector P805 and connect
the negative ( - ) terminal lead of the digital multi-
meter to the ground ( GND ) pin of P805.
6) Adjust variable resistor VR551 to match the Va
voltage specification shown on the label attached to
the panel. ( Deviation: ±0.5v )
7) After confirming the Vs and Va run voltages, the
set is ready to reassemble.
