Trouble Shooting; Warnings - O&O DEC-BT Manuel D'installation Et D'utilisation

FEASIBLE PROBLEMS
1) The LEDs of the inputs of safety devices are lit correctly but
when an input is given, the motor fails to start.
2) When an input is sent to the motors, they make a brief move-
ment and then stop straight away.
3) The motors work "hands on" with the control unit programmed
in automatic or semi-automatic cycle.
4) The electric lock does not unlock.
5) With operation with limit switch and reverser, the leaf reverses
the movement at the end of travel position entering "anti-cru-
shing" mode.
6) The LEDs of the inputs fail to light up.
You are recommended to fulfil an installation that includes all the accessories required to guarantee operation according to current stan-
dards and always using original O&O devices.
These devices must be used and installed in strict compliance with the instructions supplied by the manufacturer, who cannot be held
liable for any damages deriving from improper or unreasonable use.
O&O srl declines all forms of liability with regard to any errors possibly written in this handbook and reserves the right to add any modi-
fications considered necessary at any time without notice.

13. TROUBLE SHOOTING

- Make sure the motors are actually connected to the control unit; if
one is disconnected, a protection circuit will not allow the automatic
program to start.
- The programming method is different for two leaves or for single leaf:
for single leaf DIP SWITCHES 5 - 6 OFF in programming.
- If the Failsafe function is enabled, make sure the power supplies of the
photocells between tx and rx are different.
- A photocell is faulty or obscured during the failsafe function.
- The DIP SWITCH 1 must be ON so that "pulse" mode is set.
- The power regulation circuit could have been damaged by a short-circuit.
As a matter of safety, the gate just moves in "hands on".
- Check the integrity of the 2A fuse F3.
- Make sure the limit switches trip earlier than the actual mechanical
locking device of the leaf.
- Slightly increase the torque and the slowdown speed after making sure
the leaves run smoothly.
- Make sure jumpers have been installed on the N.C. inputs correctly on
the mutual line and then check the 315 mA fuse F1.
