Elkhart Brass SIDEWINDER 8494 WATER VALVE - Manual (Page 2)

Checking for motor power output.
2. Disconnect the 2-position harness connection (P14 & J14) at the valve and check
for power using a Volt Meter at P14. Perform test with power turned on to both
Monitor and Valve Control Modules. Connect meter Positive to female contact
(Red/White wire color) and meter negative to male contact (Black/White wire color). If
you have a Joystick squeeze and hold trigger or place the water valve switch to the
ON position. If you have a switch box control place the water valve switch in the ON
position. The meter should read negative (-) voltage. If you have a Joystick release
the trigger or place the water valve switch in the JOYSTICK position. If you have a
switch box control place the water valve switch in the OFF position. The meter should
read positive (+) voltage. (Once a switch is activated the motor voltage can only be
maintained continuously for approximately 12 seconds before the Valve Module cuts
it off. This is a feature to prevent continuous motor stall in the event of position sensor
failure. If motor power does not cut off in both directions within 10 to 14 seconds
replace the valve control module.)
 Passed; If testing detects power in both directions repair or replace motor
assembly and move on to step 8. The 12v & 24v systems both use the same 12v
valve motor. The valve motor may also be tested by applying 12v power to the
contacts in J14. Positive to male contact, negative to female contact closes the
valve. Reversing polarity reverses the valves direction of travel.
o To repair by replacing the motor only order motor p/n 46062000 2 each of
o-ring p/n 57348000. These two o-rings are to be coated with grease and
put onto the motors output shaft before attaching it to the mounting plate.
o To replace the motor assembly order p/n 81147001.
 Failed; If power is not detected in both directions move to step 3.
3. Disconnect harness connector P12 & J12. Repeat the tests from step 2 In the
output harness connector on the valve control module (J12) with the meter Positive
connected to the contact in position G (Red/White wire color) and the meter Negative
connected to the contact in position E (Black/White wire color). Once again you
should get (-) negative voltage from an OPEN command and (+) from a CLOSE
command. Remember the 12 second power cut-off.
 Passed; If the testing is successful replace the harness between the valve
control module and the valve with a new harness and start over at step 1.
o See Item 10 on the system layout drawing that matches your system
voltage. Choose the p/n for the length you need.
 Failed; If the testing is unsuccessful move to step 4.
