Although I’ve enabled it many a time, my memory is a bit foggy on the exact steps (that’s what happen when you retire).  I will tell you that you need the 3500 Rack Configuration software.  It is highly like that if you open that software, then go to Help and type in “trip multiply” that you will find very specific guidance.  I’m not at my PC, so check back later and I may be able offer some more help.

Some items worth reading are at https://www.maintenance.org/fi...p_Multiply_sabin.pdf and https://www.bakerhughes.com/be...elligent-machine-age

Can anyone explain how to do hardware setting in TM 

If you have any of the 3500 rack modules, the setup is covered in the content of the individual monitor manual.  The one I just looked at is the 3500 42M monitor.

Ali,

Warning! TM when incorrectly set can lead to major damage to the asset.

TM is configured in the rack (protection system), not in System1 (analysis software). One needs the following steps to make the TM active:

1. Establish the new trip setting you need. TM is the ratio of the new setpoint to the old setpoint. Max TM is 3.
2. Decide when TM starts and stops. These two events must be clearly defined by a traceable parameter/signals.
3. Connect the necessary wires to the rack to instruct the rack to start and stop the TM based Step 2.
4. Using the 3500 rack configuration software, change the TM setting from the default value of 1 to the new value calculated in Step1.

Important Note: if 3500 rack is standard, TM affects all cards and channels in the rack when it's active. The TM is not configured for a specific parameter (e.g. 1X), channel (e.g. channel 3) or slot (e.g. slot 4). So, if the rack is connected to more than one machine, all will be affected.

I hope this helps a little.

Thanks a lot

much appreciated

Ali Al-Shurafa makes a very good point. In my view, TM is thought of more casually than it used to be or should be. TM is a serious intervention. One should consider whether it is needed, or wheter something else can be used.
