CALIBRATE THE TEMPERATURE NOR THE
ULLAGE / INTERFACE.
9.4.1.
Disconnecting the old sensing probe
− Unscrew the securing screw with the 1.5 mm
Hex Allen key.
− Pull carefully the adaptor out of the sensing
probe tube by turning it slightly left and right.
Make sure that the O-ring is not damaged
when it passes the hole of the sensing probe
tube.
− Disconnect the plug by pulling it gently out of
the tube.
9.4.2.
Connecting the new sensing probe
− Refer to Figure 10-8.
− Insert the Insertion tool gently in the free
external holes of the tape plug.
− With one hand keep the sensing probe and the
tape adaptor as shown on Figure 10-8.
− With the other hand drive the plug into the new
sensor tube with the Insertion tool to connect it
to the sensing probe socket. Note this is a one
way only plug. The wires shall be on the
opposite side of the electronic circuit print as
shown on Figure 10-8.
− Pull out gently the Insertion tool from the plug.
If needed, keep the plug in place with another
non sharp tool, for instance the 4 mm Allen
key. Check that the plug is fully inserted.
− Switch on the unit and wait a few seconds. If all
is OK, the temperature is displayed and the
buzzer beeps every 2 seconds. If there is any
problem, refer to the section 11 "Trouble
shooting"
− Put some light grease on the O-ring.
− Push gently the adaptor into the sensing probe
tube. Mind not to damage the O-ring when it
passes the screw hole.
− Screw the securing screw back with the 1.5
mm Hex Allen key.
