What to do if...?
Problem Remedy
Tubular drive overruns the limit position or does not reach the
set limit position. Repair electrical installation and reprogram limit positions.
Check electrical installation; remove external devices; reset
limit positions.
Stops have broken off or one or several attachments are
broken. Repair system; delete limit positions, then reprogram
limit positions.
Tubular drive stops arbitrarily; cannot be restarted in the same
direction. Tubular drive is overloaded. Use a higher-torque tubular drive.
Ensure that the system runs smoothly.
Tubular drive does not run in the right direction. Tubular drive is overheated. The tubular drive is operational
again after a few minutes.
Tubular drive is faulty (does not run even after standing still for
a long period of time). Replace the tubular drive.
Clear and remove the obstruction and set the drive in the direc-
tion required.
Check the electrical connection.
Tubular drive only runs for approx. 1 second. Tubular drive is faulty. Replace the tubular drive.
Setting the limit positions using the programming unit does not
work. Set both switches to the delete setting.
Execute a short drive command.
Set both switches to the programming setting simultaneously.
Re-set the limit positions using the programming unit.
Setting the limit positions using the switch does not work. Set both switches to the delete setting.
Execute a short drive command.
Re-set the limit positions.
Tubular drive switches off automatically before the first limit po-
sition is programmed. Tubular drive has detected a torque increase.
Clear and remove the obstruction. Then move past this position
to the desired limit position.
When you attempt to set the limit positions using Auto-install,
this does not work. Close to the desired extended limit position and set a point.
The stop behaviour cannot be changed. Move to the stop limit position, and delete them individually us-
ing the programming unit. Move the system to a point between
the limit positions. You can now change the stop behaviour.
