Description of the functions of External rotor equipment in Fan and motor
External rotor 5-step: Fan drive by Rosenberg external rotor motor mounted directly on to the impeller.
Manual rotation speed control by transformer in five steps via the step speed control built into the switch box housing.
External rotor 3-step: Fan drive by Rosenberg external rotor motor mounted directly on to the impeller.
Manual rotation speed control by transformer in three steps via the keys ofthe remote control display of the AB and AD series of appliances.
Description of the functions of Standard motor equipment in Fan and motor
Standard motor single speed:
Fan drive by single-turn IEC standard motor.
Implementation of the function with TR devices
Manual switching of the rotation speed 0 /1 with the switch built into the switch box housing.
Implementation of the function with AB and AD devices
Manual switching of the rotation speed 0 /1 with the keys of the remote control display, timer switch programs
Standard motor 2-step:
Fan drive with two-turn IEC standard motor.
Implementation of the function with TR devices
Manual switching of the rotation speed 0 / 1 / 2 with the switch built into the switch box housing.
Implementation of the function with AB and AD devices
Manual switching of the rotation speed 0 / 1/ 2 with the keys of the remote control display, timer switch programs
Standard motor 3-step:
Fan drive with three-turn IEC standard motor.
Implementation of the function with TR devices
Manual switching of rotation speed 0 / 1 / 2 / 3 with the switch built into the switch box housing.
Implementation of the function with AB and AD devices
Manual switching of rotation speed 0 / 1 / 2 / 3 with the keys of the remote control display, timer switch programs
Standard motor continuous: Fan drive by IEC standard motor in combination with a frequency converter.
Continuous manual or automatic rotation speed control of the fan with the keys of the remote control display with respectively control functions.
EC external rotor motor: EC external rotor motor in the setup as a freely rotating wheel or in the single
inlet spiral housing. Continuous change of rotation speed with external EC controller in protection type IP 20.
Smooth start: Smooth start for single speed standard motors from 5.5 kW to 30.0 kW. This function is absolutely essential for motors with greater power of 5.5 kW upwards.
The Technischen Anschlußbedingungen (TAB, technical connection conditions) of the responsible energy supplier are to be observed.
Motor protection with PTC resistor: This series of devices is equipped with a PTC resistor activation device and it thereby permits temperature monitoring of the drive motor with PTC resistors built into the coil.
Motor protection with Thermocontact: This series of devices is designed for motors with thermocontacts built into the coil. With drives using standard motors one should ensure that with a capacity of ≥2.2 kW upwards, they are not operated with a thermocontact.
Outlet air fan separately switchable: In this device setup, two five-step switches are mounted in the switch box housing. Thanks to this measure the inlet and outlet air fan can be run at different rotation speeds.
Air flow monitoring inlet and outlet air:
With the help of an electronic flow sensor the air flow is monitored and when it falls below the adjusted limit, an error message is displayed.
With fans with belt drive, this function can be used to monitor the belt drive
Volume of flow display
The current volume flow of the inlet or outlet air fan is shown in the display of the remote control panel. This function is however only possible if the respective fan is equipped with a ring measurement circuit.
