Specifications are subject to alteration without notice
The control units initiate individual alarms. The alarm outputs can
be connected in parallel or in series in order to obtain a collective
alarm.
Model E can also use the analogue output signal in order to control
other drive systems. Terminals 54(-) and 55(+) are connected to
terminals 34(-) and 33(+), respectively. The DIPswitches on all
control units are set as described in ”Setting the DIPswitches”.
SPEED CONTROLLER
If a faster and stiffer controller intended for use with stiff belts is
used, the DIPswitch 5 should be set to ”On”. If a smoother controller
intended for other belts is used, the DIPswitch should be set to
”OFF”.
If the stiffer controller is not adequate for smooth oper-ation when
the max speed is set to 100%, an even stiffer and faster controller
can be selected by setting DIP switches 5 and 7 ”ON” and setting
DIPswitch 8 ”OFF”.
ROTATION MONITOR
The rotation on the motor is monitored with RotoSens by
measurement of the motor load.
For operations without the rotation monitor with sensor or the
RotoSens rotation monitor, set DIP switch 4 to ”OFF” and fit a jumper
between terminals 31 and 32.
DIRECTION OF ROTATION
HEAT RECOVERY ON COOLING RECOVERY,
SUMMER/WINTER SWITCH
Cooling energy recovery is most simply obtained by using an
external regulator which has this function
Cooling energy recovery is most simply obtained by using an
external regulator which has this function built-in. the EMX-R is then
controlled by a control signal, e.g. 0-10 V.
If, for example, an external controller is already installed, you can
obtain the cooling energy recovery function by directly connecting a

separate differential thermostat to the EMX-R, terminals 36-37.
Model E has a built-in differential thermostat. This makes it possible to
connect two NTC sensors of resistance 2000 Ohm (EGL511, for instance),
one in the incoming air duct and one in the exhaust air duct, directly to the
EMX-R, terminals 51-53.
ANALOGUE OUTPUTSIGNAL
(available on Model E only)
The output signal, 0–20 mA or 0–10 V is proportional to the speed of the
motor. The maximum value, 20 mA, is always obtained at the selected
max speed (60, 80 or 100% of the motor’s maximum rpm). The choice
between the 0–20 mA output signal and the 0-10 V output signal is made
with jumper J1 positioned behind the control terminals 51–58.
POTENTIOMETER WITH LOW RESISTANCE,
100 OHM - 5 KOHM
(available on Model E only)
When control is provided by a potentiometer with a total resistance
value between 100 Ohm and 5 kOhm, the three leads are connected
to terminals 56-58. DIPswitches 1-3 are set in the same way as for a
control signal of 0-10 V.
