2.2.8 Speed controller
DIP switch 5 on the control unit can be used to select between two speed
controllers. One controller provides gentler operation and is used if resilient
belts such as round belts, flat belts and resilient V-belts are fitted. In this case
DIP switch 5 should be set “OFF”. The other controller is faster and stiffer, and
is intended for use with stiff belts such as V-belts and homogenous round belts.
In this case DIP switch 5 should be set “ON”.
If the stiffer controller is not adequate for smooth operation 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 DIP switch 8 “OFF”.
2.2.9 Parallel connection
If several rotary heat exchangers are to be used 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 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 DIP
switches”. DIP switch 1 and DIP switch 3 on the other control units are set as
described in “Setting DIP switches”, while DIP switch 2 is always set as
described below:
The control units give 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(+),
