Status Indicator RAPs
12A-171 HVF Power Distribution RAP
The HVF has an integral power supply pro24V and +5V supplies to the HVF PWB and
HVF BM PWB. The AC power for the HVF power supply comes from the LVPS and base mod-
ule of the machine. Refer to
Figure 3 for component location.
Initial Actions
WARNING
Ensure that the electricity to the machine is switched off while performing tasks that do
not need electricity. Refer to
GP 14 . Disconnect the power cord. Electricity can cause
death or injury. Moving parts can cause injury.
WARNING
Take care when measuring AC mains (line) voltage. Electricity can cause death or injury.
CAUTION
Do not connect the HVF power cord directly to the AC wall outlet. The HVF cannot operate
without the machine. The machine controls the distribution of electricity to the HVF/HVF BM for
correct power on and power off sequencing.
• Ensure the HVF/HVF BM is correctly docked to the machine and all interlocks are closed.
• Check the interlock actuator for damage.
• Refer to HVF PWB and BM PWB LEDs to identify the status of the PWB’s.
Procedure
Figure 1 shows the component locations.
Close or cheat all the HVF BM interlocks. The HVF BM performs a mechanical reset.
