is intended for speed control of EC motors with 10V reference output and 0-10V control signal.
The speed is adjusted on the button on the front.
All fans are connected in parallel and receive via RJ45 Pin4 the same 0-10V control signal for speed control.
The status of the fan chain is indicated by two built-in LEDs. The green LED indicates status “OK”. The red LED indicates state of alarm “ERR”, i.e. at least one fan in the group has failed and interrupted the group-alarm loop as a result of this.
If there is no failure in the chain, there will be a “closed loop connection” between RJ45 Pins 7↔8 (external alarm). Once GND signal is applied to terminal 8 / JP45-Pin8, the LEDs will change from red to green indicating no error and the alarm relay is energized at the same time.
