0000001801 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. At N = N1 and control lever position a (corresponding to shim thickness L), measure the injection quantity, calculate the voltage from the graph, and then adjust the potentiometer. A:Performance standards C:Position of the control lever N:Pump speed Vo:Output voltage E:Conversion formula (J) G:Idle H:Full speed K: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.

0000001901 W-CSD ADJUSTMENT

Adjustment of the W-CSD Adjust the timer stroke using the screw so that it is as determined from the graph. Caution: The temperature of the wax at adjustment must not exceed a. A:Screw B:Timer stroke graph X:Temperature t Y:Timer stroke TA

0000002001 DASHPOT ADJUSTMENT

Adjustment of the dash pot 1. Insert a block gauge L1 (thickness gauge) between the idle set screw (C) and the control lever (D). 2. In the above condition, adjust the position of the dash pot so that the dash pot adjustment screw (A) contacts the push rod and then fix the screw using the nut (B). TT Note: (1)The adjusting screw and pushrod contact faces must be smooth. (2)Confirm that the control lever returns to the idling position. ISC actuator installation 1. Maintain the control lever in the idling position. 2. Fix actuator bracket (F) so that the gap between the control lever and the ISC lever's roller (E) is L2.
