Test procedure 1
Step 1
The valve should be in the closed position. This can be seen by the GREEN LED on the
top of the control top.
Step 2
Carry out the following steps:
Activate the lower seat lift operation by activating solenoid Y2 from the PLC.
When the seat moves downwards (approx. 6 mm), the GREEN LED on the top of
the control top will turn off to indicate that the position detecting device no longer
sees the lower seat in its closed position.
If the GREEN LED does not turn off, the position detecting device is NOT
adjusted correctly and the adjustment procedure described under “Adjusting the
Position Detecting Devices“ (Page 34) of the Operating instructions should be
repeated.
Done
Step 3
Carry out the following steps:
Activate the upper seat lift operation by activating solenoid Y3 from the PLC.
When the seat moves upwards (approx. 2 mm), the YELLOW LED on the exter-
nally-mounted lantern proximity switch will turn off to indicate that the proximity
switch S3 no longer sees the upper seat in its closed position.
If the YELLOW LED does not turn off, the upper seat proximity switch S3 is NOT
adjusted correctly and the adjustment procedure described under “Adjusting
Control top T.VIS M-15“ (Page 36) of the Operating instructions should be
repeated.
