English / Instruction
a pulse for each turn of the rotor. The rotation guard activates an alarm if the rotor
fails to rotate because of a fault.
Reversing rotation direction
The rotation direction of the motor can be reversed in order to ensure that the rotor
always turns in the right direction in relation to the purging section. The motor is
reversed by activating terminals 12 and 13 (see fig. 2).
Motor rotation ClockWise (CW) or CounterClockWise (CCW) is set by means of a
DIP (see fig. 2)
Motor type
The controller is factory set for the correct motor type by means of a DIP switch
(see fig. 2). Note that only one of DIP switches 4, 5 and 6 must be ON.
If the controller is set for the wrong motor type, malfunction may result due to
insufficient torque. There may also be higher noise emission and the motor may
overheat.
Test button
If the "max speed" test button is pressed (see fig. 2), the 0-10 V input is automati-
cally raised to 10 V, increasing motor speed to the max. setting. It is not neces-
sary to deactivate the 0-10 V signal beforehand. Any alarms should, however, be
deactivated first.
Modbus
If RHX2M is connected to a Modbus network with valid communication, the 0-10 V
signal, digital inputs and DIP switch settings are generally ignored. The motor type
DIP switches must, however, be set correctly for the actual motor type used.
The purging function, compensation for non-linear heat transfer and test switch
are all deactivated. Changes made to the maximum speed setting via Modbus only
take effect once the motor is stopped. Changes made to any other settings are
implemented regardless of whether the motor is running or stopped.
Modbus protocol
RHX2M has the address 0x4F (79) and the following communication protocol: 38.4
KB, 1 start, 8 data, 1 stopbit and no parity.
The Modbus ports A and B are connected in parallel within the RHX2M unit, and
can be used for ongoing loops.

Motor current during normal operation,
default setting is max. value.
RHX2-12M: typical 2500=2.5 A,
max. 2900=2.9 A
RHX2-14M: typical 3500=3.5 A,
max. 3700=3.7 A
5000 = 5.000 A
RHX2-16M: typical 4500=4.5 A,
max. 5000=5.0 A
Increasing current also increases torque,
acoustic noise, power consumption and
motor temperature. Reducing current has
the opposite effect.
