Rollshutter Installation Instructions, 24

remained switched in the "up" direction. The motor runs up momentarily until the limit switch cuts off power again.
Then the cycle repeats. Contact the factory and request a new motor.
Problem: The motor makes a grinding sound and/or it chatters when it reaches either of its limits.
Explanation: This is the case when the installation includes more than one motor connected to one switching
mechanism. Usually motors connected to one switch will experience capacitor feedback, unless the motors were
specially designed for this type of hook-up and the hook-up is shown in the wiring diagram. Cut all power immediately.
Hook up only one motor to one switching mechanism. Try again with the correct hook-up and verify that motors run
properly now.
Note that it is quite probable that the limit switches and/or capacitors in the motors were damaged due to the initial
faulty hook-up. Notify the factory of the incident and discuss the problem. In any case it is likely that these motors will
fail in the future either by not running at all or losing one or both of their limit switches. Without limits, the customer
may experience catastrophic destruction of the Rollshutter units as the motors turn indefinitely. It is highly advisable to
exchange the motors now in order to avoid very costly repairs later.
Section 14: Locks
If the Rollshutters were ordered with any type of manual locking systems read through this section. Otherwise proceed
to the next section. Note that key switches for motorized Rollshutters are covered in the wiring diagrams available from
Talius or from mytalius.com. If the unit was ordered with hanger locks the instructions for installation can be
found in sections 7 and 10.
14.1a) Manual Sliding Lock Bars: Manual slide locks are activated by sliding two metal bars into openings inside the guide
rails when the Rollshutter is in the down position. If the Rollshutters are supplied with manual pull down handles install
them on the bottom profile where convenient. The factory may already have done so.
Problem: The manual sliding locks do not lock the Rollshutter curtain down.
Solution: The guide rails may have been installed upside down. Check if there is a slot in the bottom of the guide rail's
channel. If it is on top instead, remove the guide rail and turn it upside down. Note that some guide rails are not
symmetrical and therefore it may be necessary to interchange right with left guide rail.
14.1b) Centre Key Locks: Centre Key Locks are operated manually with a key activating metal lock bars into a slot inside
each guide rail's channel. There is one key lock activating a lock bar on both sides of the curtain. The lock may be
operated from inside or outside the Rollshutter. If the Rollshutter is supplied with pull down handles mount these on
the bottom profile where convenient. The factory may already have done so.
