----------
T1=AD80
----------

Timer adjustment

Test data 106991-1922
(1)Adjusting range (2)Step response time (N): Speed of the pump (L): Load (theta) Advance angle (Srd1) Step response time 1 (Srd2) Step response time 2 1. Adjusting conditions for the variable timer (1)Adjust the clearance between the pickup and the protrusion to L.
----------
L=1-0.2mm N2=800r/min C2=(8)deg t1=1.5--sec. t2=1.5--sec.
----------
N1=950++r/min P1=0kPa(0kgf/cm2) P2=392kPa(4kgf/cm2) C1=8+-0.3deg R01=0/4load R02=4/4load

Test data 106991-1922
F:Full speed I:Idle (1)Use the pin at R = aa (2)Stopper bolt set position 'H'
----------
aa=41mm
----------
a=25.5deg+-5deg b=(34deg)+-3deg

Stop lever angle

Test data 106991-1922
N:Pump normal S:Stop the pump. (1)Use the pin at R = aa (2)Set the stopper bolt so that speed = bb and rack position = cc. (Confirm non-injection.)
----------
aa=40mm bb=0r/min cc=1.5+-0.3mm
----------
a=20deg+-5deg b=43deg+-5deg

0000001501 RACK SENSOR

Test data 106991-1922
Rack sensor adjustment 1. Flange type rack sensor (rack sensor adjustment -5*20) (1)These types of rack sensors do not need adjustment. Confirm the performance with the following procedures. (2)Mount the rack sensor main body to the pump main body. (3)Fix the pump lever at full. (4)At supply voltage V1, pump speed N1 and rack position Ra, confirm that the amp's output voltage is Vist. (5)Move the pump lever two or three times. (6)Set again to full. (7)Confirm that the amplifier output voltage is Vist. (8)Fix the caution plate to the upper part of the rack sensor. (For those without the caution plate instructions, make sure the nameplate of the rack sensor carries the "Don't hold here" caution.) (9)Apply red paint to the rack sensor mounting bolts (2 places).
----------
V1=5+-0.01V N1=790r/min Ra=R1(11.8)+0.05mm Vist=1.55+-0.14V
----------

Timing setting
