O2 Trim 2-5
PLL52 O2 Module
(LMV52 only)
The PLL52 module serves as the CANbus interface for the QGO20 oxygen sensor, ambient
temperature sensor, and flue gas temperature sensor.
This module is necessary if O2 trim is used.
The PLL52 module must be mounted so that the wire length from the O2 sensor to the PLL52
module does not exceed 25 feet. To mount, the lid of the module must first be removed. After the
lid is removed, four holes will be available to use with self tapping or machine screws.
Please see Section 10-1 for specifications.
