Dear All We are using Honeywell make Modutrol Motor (Model- M7284C1000) in our Burner system. The Modutrol Motor is acting as a damper actuator, it has been controlled by 4-20 mA which is outputted by Analog O/P Module( Model - SM 332). We are recently facing problem in this system for few of our customers. Problem: We are observing that whenever these Modutrol Motors become faulty like the modutrol motor stopped working on getting the mA supply from the Analog O/P Module, after a few days of time the Analog O/P Module started showing 'SF' error LED ON and then we did not get the mA output from the Module from any of the 8 channels. We have observed that: I. For faulty Motor, the resistance between ‘+’ and ‘ – ‘ in the Terminal board of Motor is somewhere between~ 5.1KOhm to ~ 56 KOhm. II. For OK motor, the resistance between ‘+’ and ‘ – ‘ is somewhere between ~101Ohm and 120 Ohm. My question is: In the present connection system of Analog O/P Module and Modutrol Motor, if Modutrol motor is faulty, can it also make Analog O/P module faulty? - which is happening for few of our customers. We have thoroughly checked all the connecting cables- found OK. Thanks Rajib.

Thread closed, because question is already published in the following thread CAN A FAULTY MODUTROL MOTOR DAMAGE AN ANALOG O/P MODULE - SM 332. Best regards O_Moderator |
