4–4 POWER SUPPLY ADJUSTMENTS (continued)
This section provides power supply adjustment procedures for the LOGIQ 500. Adjustments should be only made
when necessary. Power supply adjustments should be made in accordance with the schedule for periodic mainte-
nance in Chapter 7 of this manual.
Before beginning the power supply adjustments procedure, make sure the power outlet should provide the power line
standards. Refer to Chapter 2, Installation.
If the adjustment pot is over–turned clockwise, the power supply output is down to protect the circuits
against the over–voltage. In that case, power the LOGIQ 500 OFF and turn the pot counterclock-
wise all the way. Then power it ON and try to adjust the power supply again.
There are five power supplies in the bottom of the LOGIQ 500. These power supplies are located at the bottom of the
console as shown in ILLUSTRATION 4–31 on page 4–39.
