External Sensor For Rotation Monitor (Option); Connection - Emotron EMX- R Betriebsanleitung

2.1.1

External sensor for rotation monitor (option)

The magnet for the rotation sensor is mounted onto the periphery of the heat
exchanger. If the heat exchanger rotor cover is magnetic, the magnet must be
insulated from the cover. The rotation sensor is mounted such that the magnet
passes at a distance of 5–8 mm, see below.

Connection

WARNING! Residual voltage remains for up to 1 minute after
disconnection of the supply voltage.
The motor is delivered with a fixed connected motor cable to simplify
installation of the drive system. The length of the cable is 2.0 m for EMX-R
15M and 2.5 m for EMX-R 25M and EMX-R 35M.
In order to secure the function of the EMX drive system, do not change the
length of the motor cable. This could interfere with the electronic tachometer
that is built into the system.
An external slow-blow fuse rated at <10 A must always be installed. The drive
system does not contain a fuse. Electronic motor protection is built into the
control unit, and monitors the motor at all times. The control unit is protected
from short circuit within the motor.
