Maintenance - LockMaster DSC 600 User Manual

The gate can open,
but fails to close.

Maintenance

Every six months check the following items for proper operation of the unit.
* Lubricate shafts and sprockets.
* Keep opener clean at all times.
* Check and tighten anchors bolts.
* Check for loose or corroded wire
* Ensure the opener is well earthed, and correctly terminated.
* Always check the Stop/Reverse in case of obstruction function when performing any maintenance. If
this function can't be made operable, remove this opener from service until the cause of the malfunction
is identified and corrected.
3. Maybe the magnet position was installed in the middle so it inducts both
switches. Adjust the magnet higher or lower.
1. Photocell is obstructed. Remove obstruction.
2. The limit switch is failed. Use a jumper wire to short terminal 4 with
terminal 3 and 5, and then use a keying device to operate the opener, replace
the higher limit switch if the motor couldn't run in clockwise direction, and
replace the lower limit switch if the motor couldn't run in counter-clockwise
direction.
3. Replace the control board.
