Checking the vacuum column level sensor
Proceed as follows to dismantle the vacuum column level sensor:
1. Undo the safety screw (A) on the plug (B).
Pull out the plug (B).
Screw out the level sensor (C) with an SW30
open-jaw wrench.
2. Clean the level sensor.
3. Check the level sensor for correct function by
monitoring the signal at the PLC input.
Switch on the FAM at the main switch to
accomplish this.
During the check, hold the level sensor the
same as in the installation position. This means
that the plug is directed downward.
Afterwards, slide the lower float on the level
sensor up and down by hand.
Attach the plug for verification. See the
"Switching status" illustration on page 115. in
this connection.
If the upper float is slid upward, then the fault
message "Vacuum column overflow. Please
drain vacuum column and troubleshoot cause."
must appear on the display. Acknowledge the
message with the F3/"RESET" key.
!
4. Perform the assembly in reversed order of
sequence.
