3. Locate the volt sensing relay. See Figure 3-3. Locate the green LED and two
adjustment screws on top marked: PICK UP and DROP OUT.
4. Turn each adjustment counterclockwise to the MIN setting.
5. Plug in the system and, while monitoring the green LED on top of the volt
sensing relay, turn the system on.
If the operating line voltage is 110V, the LED will be off. If the line voltage
is 220V, the LED will be on.
6. If the vacuum pump is not operating, continues to blow fuses, or the LED
is not on at 220V refer to Section 3.5, Vacuum System Troubleshooting
Guide.
NOTE:
Make certain that the sytem's power switch is in the off
position prior to plugging the system into the AC power
source. This allows the volt sensing relay to sense the line
voltage and to switch over before the digital signal turns
the vacuum pump on.
