Emergency Shut-Down; What Do I Do If - RADEMACHER 2540 06 36 Instrucciones De Montaje

Trial run / Changing the limit stops
Check your settings and raise and lower the shutter until the limit stops turn off
the motor.
Thermal protection
The tubular motors are designed for short-term operation
(approx. 4 min)
Operating the motors for longer or frequent switching can cause the motor to heat
up and to be switched off by the thermal protection.
If this happens, leave the motor to cool down for 20 minutes.

Emergency shut-down

Function:
After approx. 2,5 sec. the tubular motor stops automatically when
the shutter is blocked by an obstacle when being raised (e. g. if the
shutter is iced up).
NOTE
Never attempt moving iced-up roller shutters. Remove obstacle and relieve shutter
in down direction.

What to do if... ?
...the motor doesn't start up?
Possible cause:
◆ There is no mains voltage.
Solution:
◆ Check the supply voltage (230 V) using a voltmeter and check the wiring.
◆ Please pay particular attention to the information on impermissible wiring
configurations.
...the direction of rotation is incorrect?
Possible cause:
◆ The control wires are the wrong way round.
Solution:
◆ Disconnect the power cable from the mains and change the cores for direction of
rotation 1 and 2.
...the tubular motor comes to a stop when adjusting its settings or
during the trial run after running for only a short period of time?
Possible cause:
◆ The adapter (10) may have slid off the limit ring (18) at the motor head (10).
Solution:
◆ Please check whether the adapter (10) is flush with the motor head (12) of
the drive and is fully inserted into the winding shaft (5).
Adjust the adapter (10) in such a way that it is flush with the motor head
(12) and push the winding shaft (5) onto the adapter (10) (see figure  ).
If necessary, re-adjust the limit stops (see page 55).

Changing the limit stops
Raise/lower the shutter half-way and start from the be-ginning.
...the tubular motor comes to a stop halfway between the two different
limit stops when in normal operating mode?
Possible cause 1:
◆ The roller cap (4) may not have been secured to the winding shaft (5) with a screw
(see figure ), which can cause the winding shaft (5) to slide off the motor
and thus pull the adapter (10) off the limit ring (18) at the motor head (12).
Solution 1:
◆ Check both the roller cap (4) and adapter (10) position. If necessary, screw the
roller cap (4) to the winding shaft (5) using a lock screw and fasten the motor
according to the information provided on pages 48 - 51.
Possible cause 2:
◆ The thermal protection has activated.
Solution 2:
◆ Leave the roller shutter to cool down for 20 minutes.
...the shutter stops during raising?
Possible cause:
◆ Iced-up roller shutter or an obstacle in the track.
Solution:
◆ Remove ice or obstacle.
◆ Relieve the roller shutter in down direction.
