Over Crank-Common Failure Jumper:
This jumper is yellow insulated and located by the side of OPR relay and marked "O"
& "F". There are two positions with three solder holes, the center hole being
common. This jumper is used for converting from a 4 light Autostart to a single light
Autostart. In the "O" position terminal 29 will signal overcrank and all common failure
inputs. Never install both jumpers at the same time. The Autostart will operate as
either an over-crank output or a common failure output.
This jumper is green insulated and located just above the CRANK & REST
potentiometers and marked "R" & "S". There are two positions with three solder
holes, the center one being common. This jumper programs SSR relay to energize to
run or to energize to shut down. The jumper will be in the "R" position for energize to
run type fuel systems. When energized to shut down, relay SSR will operate for 20
seconds. The re-crank delay jumper "C" must be clipped for timed shut down.
Crank Cycle Jumper:
Place this jumper in any position on the DIP socket from 1 to 8 for cycle seletion
(count from left to right). When this jumper is out, the Autostart will never overcrank
but continually crank until the engine runs.
All timing potentiometers adjust maxumum time in the clockwise direction and
minimum timing in the counter-clock-wise direction.
Location of the timing potentiometers are from left to right; oil pressure delay (OPD),
rest time delay (REST), crank time delay (CRNK).
Each timing adjustment should be calibrated with a stop watch. The potentiometers
are linear, therefore, adjust to a point that seems correct and then check with a stop
watch. Continue this proceedure until calibrated.
Repeatability of timing is within 1% of full adjustment.
