ATTENTION: Before performing any procedure, make sure that the device is not powered and that the batteries are dis-
connected.
The operations regarding point 5.5 are without safety devices. The trimmer can only be adjusted with door not moving.
5.1 Set dip-switches and jumpers according to door types (with or without electric lock), arm type (articulated or sliding) and
automation types (with motor or spring closing).
5.2 Set TC, VA, VC trimmers at minimum and RF at mid position.
5.3 Short circuit the safety devices (41-6, 41-8) and the stop (1-9).
5.4 (Only for WELS) Adjust desired spring closing speed by means of CLOSING SPEED LO-ME-HI jumper and HI-ADJ trimmer.
Adjust approaching speed by means of PROXIMITY LO jumper for doors without electric lock and by means of PROXIMITY
HI jumper for doors with electric lock.
5.5 Power and by means of controls 1-3 and 1-4 check that the automation is working properly. Set the automation's speed by
means of the VA and VC trimmer.
Attention: upon each turning on the control panel automatically POWER RESETs so as to permit the first opening and
closing to be made at low speed in order to learn the end-of-travel positions (acquisition phase).
5.6 Adjust thrust on obstacles and motor torque by means of RF trimmer, in order to guarantee proper and safe operation.
5.7 Make an estimate of the risks present and install and connect all the necessary safety devices (41-6, 41-8) to the electronic
control panel. Check for their efficiency.
5.8 Adjust automatic closing (enabled by 1-2 control or by COME-H-K function selector) by means of TC.
5.9 Connect any control devices and function selectors. Check for their efficiency.
5.10 If the automation encounters an obstacle during closing, it is detected and the automation opens again. If the obstacle
remains, the automation will attempt a closure at 30 s intervals, until the obstacle is effectively removed.
Attention: ensure that the manoeuvering force and the thrust between the door and the obstacle is lower than the values
set out by regulation DIN 18650-1.

99 - IP1786
Possible Causes
COME-H-K function selector with wrong set-
ting.
COME-H-K function selector not working.
Power failure.
Accessories short circuit.
Burnt line fuse.
Safety devices are triggered.
(SA led on).
Radars are not triggered (IN led off).
The door is blocked by bolts and locks.
WELS with incorrect VC trimmer adjustment.
(POWER ALARM led flashing)
Incorrect J3 setting.
(SA led flashing)
Radars are triggered.
(IN led on).
Automatic closing does not work.
Wrong connections between safety devices
and electronic control panel.
The radars are unstable or detect moving
objects.
Encoder not working.
(POWER ALARM led flashing).
Inverted motor wires.
(POWER ALARM led flashing).
Some friction is present.
Check and adjust COME-H-K function selector
settings.
Replace COME-H-K function selector.
Make sure electric control panel is powered.
(POWER ALARM led on).
Disconnect accessories from terminals 0-1 (with
24 V= voltage) and connect them again one at
a time.
Replace line fuse.
Check terminals 6 and 8 of the electronic control
panel.
Make sure photocells and safety devices are
clean and efficient.
Make sure radars are working properly.
Make sure the wing can move freely.
Check the correct adjustment of the VC.
(see paragraph 2.3)
Check the connections of the safeties as illustra-
ted in paragraphs 2.1 and 2.2.
Make sure the radar is not subject to vibrations,
nor carrying out false detections or detecting mo-
ving objects within its range of action.
Check 1-2 jumper and (if present) function se-
lector position.
Connect in series N.C. safety contacts and remo-
ve any jumper.
Make sure the radar is not subject to vibrations,
nor carrying out false detections or detecting mo-
ving objects within its range of action.
Replace encoder.
Check motor wires.
Manually check that the door wings move freely
and adjust the door wing in height by lifting it.
