5.2.2 Requirements for the shading motor
The motors used must be fitted with a limit switch (mechanical or electronic) that de-energises
the motor in the limit position. The mains power for moving the shading is available here after
switching through the relays.
The relays of the shading control switch motors up to 700 W. Also note this value for the control
of multiple motors.
Also note the maximum duration for being switched on (often referred to as “ED” in technical
texts). It can happen due to frequent moving that the motors heat up too strongly so that they
are switched off via an integrated thermal switch and do not function again until they have
cooled down.
Depending on the design of the motor, the cooling down can take up to 30 minutes.
If you want to switch the motors in parallel, the motors must be suitable for this.
Or use isolating relays (item no.: TR-S, TR-SUP or TR-SREG).
