CLIMAVENETA i-ACCURATE i-AX Installation Manual - User And Maintenance page 61

Description
This actuator with 3point or 0÷10V signal is adapt for 2 or 3 way valve with 20mm stroke
SQX82:
1 Terminal strip
SQX82...
3-position positioning signal
• Voltage on Y1: actuator stem extends, valve opens
• Voltage on Y2: actuator stem retracts, valve closes
• No voltage on Y1 and Y2: actuator stem remains in the respec-
tive position
Calibration SQX62
The minimum stroke of the valve is 15 mm. The LED does not indicate a calibration error when the stroke is < 15 mm
The stem extends to the maximum position with the maximum positioning signal DC 10 V.
Calibration
1. Pressing button S3 starts calibration
2. Actuator moves to «0 %» stroke position (valve closed)
3. Actuator moves to «100 %» stroke position (valve open)
4. Measured values saved in microprocessor
Normal operation
5. Actuator moves to the position as indicated by signal Y
A flashing red LED indicates a calibration error.

Ssignal: DC 0...10 V
The SQX62 is either controlled via terminals Y.
• Signal Y increasing: actuator stem extends, valve opens
• Signal Y decreasing: actuator stem retracts, valve closes
• Signal Y constant: actuator stem remains in the respective
position
