46 Troubleshooting
USING TEST INPUTS
The Test Input routine allows you to Test the
Flow, Speed, and Run/Hold inputs of the con-
sole.
This routine gives you a convenient way of
checking the cables and sensors along with the
Flow, Speed, and Run/Hold inputs of the con-
sole. The routine is located in the Options menu.
Refer to the TEST INPUT section on how to ac-
cess each test routine. After selecting the input
to be tested the console will do the following for
each pulse received. Flash the light, sound the
horn, and display the number of pulses received.
The count may be cleared to zero by pressing
the key.
To test the sensors first activate the proper input
to be tested then perform the necessary action
to cause the sensor to output a signal. For Flow
sensors start spraying or activate the sensor by
passing a magnet over its face. For Speed sen-
sors start driving or activate the sensor by pass-
ing a magnet over its face. For the Run/Hold
sensor press the switch or pass a magnet over
its face. The Run/Hold test routine will not cause
the horn and light to stay on constantly while the
switch is held activated. It will only give an indi-
cation (flash and beep) that the switch had been
activated.
To locate the faulty component start testing at
the sensor and work your way to the console.
Use a good sensor or momentarily short pins
one and two of the cable and check the console
for an indication.
NOTE: If pin three (12 Volts) is accidentally short
-
ed to pin one (Ground) the console will tempo-
rarily remove power from the Speed, Flow, and
Servo connections to protect itself. To restore
power shut off the console for a minute. Power
should be available the next time the console is
turned on.
CABLE AND CONNECTOR
TROUBLESHOOTING
NOTE: Splices in cables are not recommended.
If a splice is necessary to eliminate down time,
the wires should be individually soldered and
taped. (Use rosin core solder only.)
NOTE: All three wire cables are interchange-
able. EXAMPLE: A flowmeter cable can inter
-
change with a servo cable.
1. Visibly check the routing of all cables to make
sure the cables are plugged into the proper
components and the correct connector on the
console. Look for any cut, pinched, burned, or
corroded wires which may be the source for
the problem.
2. Check all connectors, including console con-
nectors. Make sure all male pins are not bent,
and are mating properly with the female sock-
et. An indentation in the rubber next to the fe-
male socket is a good indication that the male
pin is not aligned properly. Look for moisture,
dirt, corrosion, etc., on the male pins or female
sockets. To clean, spray LPS contact cleaner
in the connector. Plug and unplug the connec-
tor several times and wipe dry.
NOTE: A speed sensor cable only has one fe-
male socket.
3. Check crimp connectors; the crimp connection
in all connectors is where the wire is joined
to the male pin or the female socket. Start by
sliding the connector boot back to expose the
wires (DWG. NO. 1290). Gently tug on each
of the wires. If the wires do not pull out of the
connector the connection should be good.
Look for moisture or corrosion build-up inside
the connector boot area as this could be the
source of the problem.
