ACTIVATING OTHER FUNCTIONS
PRIORITY SWITCH / DEFROSTING /
MANUAL CONTROL
When terminal 34 is connected to terminal 35, the speed of rotation is
determined by the priority poten-tiometer, which is located next to the
DIPswitches in the control unit.
The priority switch has higher priority than the summer/winter switch
(only available on Model E) and the control signal.
ALARM OUTPUT
The alarm output is a changeover contact, max 5 A 230 VAC.
SELECTION OF MAX SPEED
Maximal speed can be limited to 80% (200 rpm) or 60% (150 rpm). This
function is intended to be used especially for rotors smaller than ca 1.3
m, when it is desirable to maximize the revolution and/or when using
larger belt pulleys.
PARALLEL CONNECTION
If several rotary heat exchangers are to be operated in parallel using one
control signal or sensor, each heat exchanger rotor must be equipped
with its own drive system (motor and control unit).
The control signal cable is connected to the first drive system according
to the instructions for connection. The other control units are connected
by connecting terminals 33 and 34 of the other control units to terminals
33 and 34, respectively, on the first control unit. The DIP switches on
the first control unit are set as described in ”Setting the DIPswitches”.
DIPswitch 1 and DIPswitch 3 on the other control units are to be set as
described in “Setting the DIPswitches”, while DIP switch 2 is always set
as illustrated below:
TEST SWITCH
When test switch is in the ”ON” position, the motor soft starts and the
speed increases to the maximum, independently of other signal sources.
When in the ”OFF” position (down) the test switch is not operational.

TIP!
The test switch can also be used to run the
motor at maximum speed if, for example, an
external control signal is not available.
