Elkhart Brass SIDEWINDER 8494 ELECTRIC - Manual (Page 4)

Problem; monitor will not stop at intended vertical travel limits.
7. Disconnect vertical position sensor connectors J06 & P06. In connector P06
check for hall sensor power (+7.5 to 12 VDC) at terminal 3 (red wire), left/right
sensor signal voltage (+4.5 to 7.5 VDC) at terminal 2 (white wire), and ground at
terminal 1 (black wire).
a) Passed; if all values were within specifications. Move on to step 9a.
b) Failed; one or more values did not meet specifications. Move on to step 8.
8. Move to the next connector in the harness towards the monitor control module
and check for hall sensor power (+7.5 to 12 VDC) at terminal position C, up/down
sensor signal voltage (+4.5 to 7.5 VDC) at terminal position J, and ground at
terminal position K. (There may be an extension harness or harnesses between
connectors P4 and J4.)

If this connector was on an extension harness move to next connector in the
harness towards the monitor control module and check for hall sensor power
(+7.5 to 12 VDC) at terminal position C, left/right sensor signal voltage (+4.5 to
7.5 VDC) at terminal position J, and ground at terminal position K. If all values
were not within specifications move to next connector in the harness towards the
monitor control module and continue testing until you get the correct values (in
which case you replace the previous harness extension) or until you reach the
control module and still do not get the correct values (in which case you replace
the control module). In either case reconnect harnesses, and go back and repeat
step 7.
9. Checking the monitor control modules travel limit function using a jumper.
a) Testing the vertical limits; While moving the monitor up electrically place the
jumper between terminal positions 1 & 2 in connector P06. The monitor
should stop and only allow downward travel until the jumper is removed.
Remove the jumper and repeat the test while going down and the monitor
should stop and only allow upward travel until the jumper is removed.
b) Testing the horizontal limits; While moving the monitor left electrically place
the jumper between terminal positions 1 & 2 in connector P08. The monitor
should stop and only allow travel to the right until the jumper is removed.
Remove the jumper and repeat the test while going right and the monitor
should stop and only allow travel to the left until the jumper is removed.
