10 Regulating linkage
32 Digital Governor Basic System PANDAROS II
10 Regulating linkage
10.1 Length of lever arm
The length of the lever arm is determined in such a way that approx. 90 % of the governor
output shaft adjustment angle can be used. Based on this, the rack length L of governors
with 36° adjustment angle is calculated as L = 1.8 a, "a" being the travel distance of the in-
jection pump or the carburetor.
10.2 Order specification for lever arm
Actuator 2010 Please order RH 2010-01
EDV- No.: 511 80 004 00

EDV- No.: 502 80 017 00
Actuator 2080 Please order RH 2080-01

10.3 Connecting linkage
The connecting linkage from the governor to the injection pump or the carburettor should
be length-adjustable and have a (pressure or tension) elastic link. If the actuators torque is
less than 10 Nm, the elastic link is not needed. If possible, joint rod heads in accordance
with DIN 648 should be used as connecting links. The linkage must operate easily and
without clearance.
In case of friction or backlash in the linkage connecting actuator and injection pump resp.
throttle valve no optimal control is possible.
