SYSTEM # 2 - Engine speed/RPM control and many other applications
On applications other than
“On-To-Run” fuel shut down, a solenoid electronic control module is required to allow the solenoid to operate in
a continuous duty mode without damaging the solenoid. W ire the solenoid and module as shown below. Do Not mount the module
directly on the engine or other high vibration point. Keep module away from direct heat sources.

3. S500-A5 & A50 Modules - After making the final wiring check, energize the solenoid hold coil by turning the switch to the
“on” position and
manually push the solenoid plunger to the seated position. The plunger should remain seated.
S500-A6 & A60 Modules - After making the final wiring check, energize the solenoid hold coil by turning the switch to the
“on” position, close
the run switch on the module and manually push the solenoid plunger to the seated position. The plunger should remain seated.

.
W ith solenoid seated, connect the linkage to the plunger , adjust the linkage for proper operation and tighten all connection points securely.
5. De-energize the solenoid. Visually check the linkage by manually moving the linkage thought its entire stroke to make sure the linkage is
free from obstructions. Total movement of the plunger
MUST NOT
exceed the recommended stroke of the solenoid.

24 Volt
Installations
Although the
module is capable
of 12 or 24 volt
input, only the 12
volt system can be
wired with its
output going
directly to the
solenoid as
depicted in the
diagrams above.
The 24 volt output
(pull-in) MUST be
wired through an
external contactor.
Failure to do so will
result in reduced
module life.
*** Note when using an S500-A50 or
S500-A60 module all of the solenoid
connections must connect to the
module as shown.
Do not
connect any
of the solenoid leads to another ground
point in the system.
* Note - some solenoids only have 2 wires.
If this is the case, use the black and either
the white or red wire connection points on
the module
