Why DKS 1601 arm rotates up, but will not rotate down?
- RRobert GreeneSep 10, 2025
If the arm of your DKS gate opener rotates up but not down: * Check the LEDs on terminals 6, 7, and 9. If any of these are ON, it indicates a shorted input holding the arm up. * Check the LEDs on the loop detectors. If any are ON, it indicates a possible loop or loop detector problem holding the arm up. * If the auto timer is not used (SW 1, switch 7 off), make sure SW 1, switch 6 is in the ON position. This will cause terminal 6 to rotate the arm down when activated. * Check to be sure SW 1, switch 4 is ON. This will cause terminal 8 activation, then deactivation to rotate the arm down.
