2.4 Trimmer
TC
Automatic closure time. It adjusts the time that elapses between the ending of opening control
and the beginning of the automatic closing. Time is renewed by controls 1-3A, 1-3B, H-3A, H-3B
and 41-8.
RF
Motor torque. It adjusts motor torque.
RF trimmer also adjusts thrust on obstacles.
If an obstacle is present, during opening operation it stops movement, whereas during closing ope-
ration it reverts movement. After the obstacle has been removed, the door automatically searches
for its stop and continues its stroke at learning speed.
Warning: if an opening control is given with the door locked, the following opening operation will
be disabled for 15 s.
VA
Opening speed. Adjust the opening speed.
VC
Closing speed. Adjust the closing speed.
Note: in WELS automations, the VC trimmer adjust the closing speed only when contact 0-1 is
connected to the BRAKE card and DIP5=ON.
Adjustments according to the operating forces. Only for WELS automations without 0-1 con-
nection to the BRAKE card and DIP5=OFF. Perform the following steps:
- Set the trimmer VC=MAX. Adjust the correct closing speed as indicated in chapter 3 and ensu-
re that the manoeuvering force and the thrust between the door and the obstacle is lower than
the values set out by regulation DIN 18650-1.
- Reduce the trimmer VC adjustment and perform the opening and closing manoeuvers. Repeat
this step until you find the VC trimmer position that causes the POWER ALARM LED to light up.
- Increase by approx. 20% the VC trimmer adjustment.
