5.8. AUTOMATIC PROPORTIONAL CONTROL WITH EXTERNAL 0-10V ANALOG SIGNAL
With same confi guration described in the previous section 5.7., possibility of automatic control
through an external 0-10V input (for example, IAQ CO2 sensor 5416845300 AIRSENS CO2).
Once this confi guration is made, the drive will operate proportionally to an external o-10V signal.
When we reach 0V, the fan will rotate at the minimum frequency (20Hz). When we get 10V, it will
rotate at maximum, 50Hz.
The remote start-stop can be carried out with a potential-free contact between the +24V–DI1 ter-
minals.
5.8.1. Wiring diagrams
Make the drive-motor connection diagram indicated in the following fi gures depending on
the type of motor used and if this motor has a thermal protector:
•
Fig.4.1.
Single phase power supply 1/230/50-60, three phase motor 230/400V without
thermal protection.
•
Fig.4.2.
Three phase power supply 3/400/50-60, three phase motor 230/400V o 400V with-
out thermal protection.
•
Fig.4.3.
Single phase power supply 1/230/50-60, three phase motor 230/400V with ther-
mal protection.
IMPORTANT: Before wiring, read points 5.2. and 5.4. to determine type of reset and
terminal confi guration (NC).
•
Fig.4.4.
Three phase power supply 3/400/50-60, three phase motor 230/400V o 400V with
thermal protection.
IMPORTANT: Before wiring, read points 5.2. and 5.4. to determine type of reset and
terminal confi guration (NC).
5.9. AUTOMATIC PROPORTIONAL CONTROL WITH 4-20MA EXTERNAL ANALOG
SIGNAL (CO2, TEMPERATURE, RELATIVE HUMIDITY)
Confi guration that allows an automatic proportional system depending on a 4-20mA analog signal.
In this way, the proportional regulation ramp can be adjusted as shown in the following fi gure:
* Factory values
To make necessary adjustment, you must fi rst inlock the equipment (see section 5.1) and then
follow the steps below:
1. Set minimum speed
“LSP”
and maximum speed
“HSP”
:
• Fan stopped and
“rdY
” displayed in the screen
(no b24V – DI3 and +24V – DI1).
• Press
ENTER
and turn wheel on clock wise direction until
“COnF-”
appears in the screen.
