Test data Ex:
0000001801 POTENTIOMETER ADJUSTMENT
Adjustment of the potentiometer
At pump speed N and with the control lever angle at a from the idle position (clearance L), convert the injection quantity obtained to a voltage value using the graph and adjust the potentiometer.
Vo:Output voltage
Q:Injection quantity
A:Performance standards
C:Position of the control lever
G:Idle
H:Full speed
E:J = formula V+-0.03 = 0.1065Q+2.8519 (Q < 15.2 mm3/st)
V+-0.03 = 0.0674Q + 3.4462 (Q>=15.2 (mm3/st)
K = Vi: applied voltage
X:Injection quantity (mm3/st)
Y:Voltage (V)
M:Connecting diagram for the potentiometer
O:Output
P:Output when (2) and (3) connected.
