10.5 Sensing probe replacement

THE REPLACEMENT
PROBE DOES NOT
CALIBRATE THE TEMPERATURE NOR THE
ULLAGE / INTERFACE.

10.5.1 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.

10.5.2 Connecting the new sensing probe

 Refer to Figure 10-9.
 Insert the 1.5 Allen key gently in the free hole
in the middle of the tape plug.
 With one hand keep the sensing probe and the
tape adaptor as shown on Figure 10-9.
 With the other hand drive the plug into the new
sensor tube with the 1.5 Allen key 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 10-9.
 Pull out gently the 1.5 Allen key from the plug
while keeping 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.
