CONNECTION
BEFORE CARRYING OUT ANY OPERATION, DISCONNECT THE UNIT FROM
THE NETWORK AND ENSURE THAT THE POWER SUPPLY CANNOT BE
SWITCHED ON ACCIDENTALLY.
This equipment must be installed by suitably qualified personnel. The installation must comply
with standard NFC15-100 and industry best practice. Each product or component used in this
installation must also comply with the applicable standards.
THE INSTALLATION MUST BE PROTECTED UPSTREAM BY A
SUITABLE MAGNETOTHERMAL CIRCUIT BREAKER.
.
Connecting to an ECM motor with 0-10
V input
- Connect the 0-10 V output
S1
and the
GND
reference of the controller to a 0-10 V analogue input on
the ECM motor.
Connecting to an ECM motor with PWM input
- Connect the PWM output
S2
and the
GND
reference of the controller to the "Rx" input on the ECM
motor.
- Place a bridge between the 0-10 V
S1
output of the controller and the
V+
input on the controller.
- In product settings, activate the option "FORCE S1 to 10V". This mode forces the
S1
output to 10.5 V
which will serve as the power supply for the PWM output
S2
to limit the amplitude of the PWM signal.
