Function

Ɣ Set the maximum engine speed under

each working mode. This set speed is the

standard to control engine speed.

Operation

Ɣ Calibrating procedure for positive flow exca-

vators.

1) Selection of fixing point of throttle motor

soft shaft

2) H, S, L maximum speed calibration, and A/

I speed calibration.

3) Turn the dial on the calibrator counter-

clockwise to the end

4) Power OFF

5) Set the calibrator to "Monitor mode", power

on and check the result.

Remark:

Memory SW up: Calibration mode;

Memory SW down: Monitor mode

4.9.11.3 Engine speed sensor

ZX215-1002211

Function

Ɣ The engine revolution sensor is installed to

the ring gear of the engine flywheel. It elec-

trically calculates the number of the gear

teeth which pass in front of it and transmits

the result to the engine controller.

Operation

Ɣ Measure the resistance between terminal

1 and terminal 2 when it is in service.

Standard value (@25°C)

2.3±0.2 kȍ

Ɣ If the measured value exceeds the stan-

dard value, replace the sensor.

CAUTION

Ɣ If the engine speed sensor is not tight-

ened to the specified torque, the sensor

may send out no signals. Tighten the

engine speed sensor to the specified

torque.

Function

Ɣ The output resistance of the engine cool-

coolant temperature. The controller collects

and processes coolant temperature signals

and works out the coolant temperature.
