7.2.6 MATCHING

7.2.6.1 GENERAL
▪ For the tilt angle, load and tire angle sensors among sensors used for SAS functions, the signal voltage
values under the mast vertical, no load and tire straight conditions are stored, respectively, in the control-
ler for the control based on these values. When servicing or replacing these sensors, matching (updating
the sensor signal voltage value in the standard vehicle condition) is necessary. Also, matching is needed
for the tilt angle sensor when the vehicle posture has changed excessively, and for the load sensor when
the load under no load condition (no load on fork) is changed because of addition or removal of any at-
tachment.
▪ Each lever angle sensor for mini lever is controlled based on the memory of signal voltage values in the
neutral position stored in the controller at the time of shipment. When servicing these sensors or repla-
cing related parts, MATCHING (updating the sensor signal voltage value in the standard vehicle condi-
tion) is necessary.
▪ Solenoid current level for the electromagnetic relief valve (EMRV) is set for each electromagnetic relief
valve, before shipping, and it is registered to SAS/OPS controller.
So "MATCHING" is necessary when maintaining or replacing parts for electromagnetic relief valve
(EMRV).

Description
Stores the tilt angle sensor output value with fork in the
horizontal position to the controller.
Stores the tilt angle sensor output value at the forward
tilt limit position and the load sensor output value with no
load to the controller.
Stores the tire angle sensor output value while the
vehicle is traveling straight to the controller.
