Dear members
I operate a komori LS840. Can anyone tell me what the function of this L M H on the dampening module. Thank you

 

His Sir:

Is for adjust the Low =30% Medium= 50% High= 70% of water

 

It's pre-damp settings. It's set at 30/50/70 but you can set every of them to desired value.

 

The ratio 120 set 20
L between 12/17 M between 20/26 H between 70/90.
It deppends of roller setting and temperature of winter and summer

 

It’s the short answer but absolutely correct.

 

Thank you guys for the info. If I read correctly, it only comes into play for pre-dampening. What happens when the press is in production after your pre-make-ready. Does this function play a part in regulating the damp feed rate in relation to press acceleration.

 

This is only pre-damp. On Heidelberg is set in revolutions, on Komori in percents. This is not related to speed. Dampening compensation to press speed is the ratio. All can be set in M1 and M2 settings

 

Thank you mate. This exactly the info I was trying to get at. Cheers
