K1 and K2 switches in TM3SAxx module

[Pedro_garcia]

Hi All,

I need o switch K1 and K2 in a TM3SAxx module but I only can with K1, do I need to have in account something special inside of the configuration?

Many thanks in advance,

Hello Pedro,

please refer to the hardware guide of the TM3 Safety Module and make sure you follow all safety instructions and information. You will find it on Schneider Electric website: TM3 Modules Hardware Guide 

The behavior you described is correct according to the design of the TM3SA** module. To have K2 set "switched on" you must have Enable set TRUE in SoMachine.

A second condition is the terminals S41 – S42.

These can be used for EDM2 (External Device Monitoring) but have to be jumpered when not in use!

See picture below from instruction sheet:

Best regards
