
IftheambientorstacktemperaturesensorwiredintothePLL52arenotreading(displayedas
“XXXX”ontheAZLscreen),orthesensorsarereadingincorrectly,checkthefollowing:

1. EnsurethatthesensorsarewiredintothePLL52modulecorrectly.SeeSection2toverify
properwiring.

2. Bothsensorsmustbea2‐wire,1000Ohm,platinumornickelRTD.Checktoseethatthe
sensorsareactivatedandproperlyconfiguredunderthefollowingmenupaths:

 Params&Display>O2Module>Configuration>SupAirTempSens
 Params&Display>O2Module>Configuration>FlueGasTempSens

 Note: TheambientandstacktemperaturesensorsarenotnecessaryforO
