2. Enable and control the steam production using:
PROPORTIONAL EXTERNAL CONTROLLER
jumper outputs M2.7 and M2.8 or connect to a remote contact
connect outputs M2.1 and M2.2 to an external controller
•
The humidier can be programmed to receive one of the following •
signals:
Voltage: 0 to 1 Vdc, 0 to 10 Vdc, 2 to 10V
Current : 0 to 20 mA, 4 to 20 mA
Potentiometric: 135-1000 ohm, 0-135 ohm

PROPORTIONAL EXTERNAL CONTROLLER WITH CAREL LIMIT PROBE
jumper outputs M2.7 and M2.8 or connect to a remote contact
•
connect the limit probe to terminals M2.3, M2.5 and M2.6•
The humidier can be programmed to receive one of the following •
signals:
Voltage: 0 to 1 Vdc, 0 to 10 Vdc, 2 to 10V
Current : 0 to 20 mA, 4 to 20 mA
Potentiometric: 135-1000 ohm, 0-135 ohm

CONTROL WITH CAREL TEMPERATURE PROBE
The humidier can be connected to both active probes (voltage or current
signal), and to passive NTC temperature probes (variable resistance).
CAREL active probe connection:
jumper outputs M2.7 and M2.8 or connect to a remote contact
connect the temperature probe to terminals M1.2, M2.2 and M2.3
