SMPS ADJUSTMENTS

This section provides SMPS adjustment procedures for the LOGIQ 200 PRO Series. Adjustments should be only
made when necessary. SMPS adjustments should be made in accordance with the schedule for periodic
maintenance in Chapter 7 of this manual.
Before beginning the SMPS adjustments procedure, make sure the power outlet conforms to the proper power
line standards. Refer to Chapter 2, Installation.
If the adjustment pot is turned to far clockwise, the SMPS output shuts down to protect the circuits
against the over--voltage. In that case, power the LOGIQ 200 PRO Series OFF and turn the pot
counterclockwise all the way. Wait for 5 minutes for recovering of SMPS protection circuit. Then
power it ON and try to adjust the SMPS again.
The SMPS Assy is in the bottom of the LOGIQ 200 PRO Series as shown in ILLUSTRATION 4--7.
