Test data Ex:
0000001801 CONTROL LEVER ANGLE
Control lever angle measurement
1. Measure dimension Ya between the end of the lever and the flange face B.
2. Measure the lever angle from the R (plate) pin hole.
(A) Lever angle measurement position
----------
Ya=8.4~12.2mm R=53mm
----------
Ya=8.4~12.2mm R=53mm Alpha=51.5~59.5deg Beta=31~41deg

0000001901 POTENTIOMETER ADJUSTMENT
Adjustment of the potentiometer
In the following condition, change the installation position of the potentiometer to adjust the output voltage to within the specified values.
Measure the injection quantity at control lever position a (shim thickness = approximately L mm) at N = N1 r/min, determine the voltage using the formula, and adjust the potentiometer.
A:Performance standards
C:Position of the control lever
N:Pump speed
Vo:Output voltage
E:Conversion formula
G:Idling
H:Full speed
K:Applied voltage
X:Injection quantity (cm3/1,000st)
Y:Voltage (V)
R:Confirm at least V3 at full lever position.

Information:
Environmental
The ambient operating temperature range is from -40° to 70°C (-40° to 158°F).
The storage temperature is from -40° to 85°C (-40° to 185°F).
The unit must be protected from direct contact with liquids. If sealing of the unit is required, the CCM must be in a water tight enclosure.
The CCM weighs 0.75 kg (1.65 lb).Mounting
The CCM can be located on a desk or on a shelf. The rubber feet on the bottom of the CCM can be removed for mounting to a panel.Note: Do not mount the CCM on the engine or within the engine mounted instrument panel. The CCM is not designed for direct engine mounting.Internal Battery
The CCM contains a battery that supplies power for internal memory whenever the CCM is turned off. Refer to the Operation and Maintenance Manual, "Battery - Replace".Power Supply
The requirements for battery voltage are 15 to 45 volts DC (24 or 32 volts DC nominal power).
The +/-B power dissipation is approximately 3.0 watts at 24 volts.
The current drawn by the CCM is 0.11 amps at 12 volts and 0.13 amps at 36 volts.
Multiple engines must share a common ground (-B).
Multiple engines must use diodes to prevent power sharing between units.Dimensions
