10.5 Sensing probe replacement

THE REPLACEMENT OF THE SENSING PROBE DOES
NOT REQUIRE TO RE-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.
