English / Instruction
motor. If no pulse is received before the motor has rotated 50 times, motor speed is
reduced to 0 rpm. Speed is then gradually increased again until the speed setting is
reached. If once again no pulse is received, this sequence is repeated three times in
all before the rotation guard alarm is activated.
Rotation guard alarms can be reset by short-circuiting the rotation guard terminals
(10-11) for at least 1 second or via a Modbus command. Rotation guard alarms
are typically caused by defective drive belt or incorrect rotor torque (see "Motor is
noisy"), a problem that occurs most often at max. air quantity through the rotor.
MOTOR IS NOISY AND RUNS UNSTABLY
Motor type
The DIP switches for selecting motor type are incorrectly set (see fig. 2) or the
wrong step motor is installed.
Rotor adjustment
Rotor turns sluggishly and step motor is overloaded.
When rotary heat exchangers/ventilation units are installed correctly, the rotor
should turn easily when pushed by hand. If incorrectly installed, the torque required
to turn the rotor may increase dramatically because:
• The ventilation unit is not level
• Rotor adjustment is lacking/incorrect
• Sealing strips and brushes are too tight
If the step motor is overloaded, it loses synchronisation and produces a lower
pulsating torque. As a result, it runs "jerkily", is noisy and does not rotate correctly.
This damages neither the motor nor the controller, however.
Once the rotor has been correctly adjusted and is capable of being turned at normal
torque, the motor can be restarted and will rotate normally.

plies with the following European Parliament directives:
2011/65/EU RoHS Directive
DIRECTIVE 2011/65/EU OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL
of 8 June 2011 on the restriction of the use of certain hazardous substances in
electrical and electronic equipment
2014/30/EU EMC Directive
DIRECTIVE 2014/30/EU OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL
of 26 February 2014 on the harmonisation of the laws of the Member States relating
to electromagnetic compatibility
2014/35/EU Low Voltage Directive
DIRECTIVE 2014/35/EU OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL
of 26 February 2014 on the harmonisation of the laws of the Member States relating

Applied standards
EN 60730-1 2011 Automatic electrical controls for household and similar
use Part 1: General requirements
EN 61000-6-3 2007 Electromagnetic compatibility (EMC) - Part 6-3: Generic
standards - Emission standard for residential, commercial
and light-industrial environments + A1:2011
EN 61000-6-2 2005 Electromagnetic compatibility (EMC) - Part 6-2: Generic

The product is designed to be incorporated in machinery or to be combined with
other machine components for incorporation in machinery covered by Directive
98/37/EEC of the European Parliament and of the Council (and subsequent amend-
ments). The product itself therefore does not comply with the requirements of this
directive in all respects.
