Additional specifications and description
The requested fan speed can be set via the analogue
input signal. This analogue signal can be 0-10V or 0-20 mA.
This analogue input can be set in ascending or descending
mode. In ascending mode, the motor will run at low speed when the
analogue signal is at its minimum value (0 V). The motor will run at high
speed when the analogue input is maximum (10 V). In descending mode, the
operation is inversed.
In case there is no 0-10V signal available, you
can connect an external 10 KOhm potentiometer via the
integrated 12 VDC power supply.
The motor can be enabled or disabled via
the illuminated on-off switch or remotely. Via an external switch, it
is possible to start the motor remotely - this optional switch can be
connected to the digital input of the fan speed controller.
For most applications, this variable speed
controller can be used with the default settings. If necessary, the settings
can be customised via Modbus RTU or via the dip
switches and internal trimmers.
The enclosure is made of high-quality
r-ABS VO (UL94) plastic. This material is flame extinguishing in case
of fire, very tough and offers good protection against impacts. The
enclosure can be surface mounted and offers an IP54
protection against ingress of dirt, dust and
The unregulated output (230 VAC) is active
when the motor is enabled. It can be used to control an external
run-indicator, a damper, etc.
E.g. when the fan is deactivated, the damper
is closed. When the fan is active, the damper is open.
fan speed controller can monitor thermal motor contacts (TK or
thermal contacts measure temperature in the motor windings). In
case of motor
the TK monitoring function will disable the motor to prevent motor damage. If
your motor is not equipped with TK contacts, bridge both TK terminals to
simulate normal motor temperature.
fan speed controller has an alarm output to generate alerts in case of motor
can be used to signal motor problems via an external buzzer or alert
