• Positioning Time Limit: Range 0...200 seconds, monitoring parameter for control until the deviation reaches the tolerance band

Installation Guide

• Check the actuator type first. Use DIN/IEC 534 or NAMUR for linear actuators.
• Use VDI/VDE 3845 for rotary actuators. Confirm the mounting kit fits your actuator.
• Connect the air pipe to the 1/4-18 NPT port. Keep supply air clean and dry.
• Connect the cable through the 1/2-14 NPT entry. Use shielded cable for the 4...20 mA loop.
• Verify the double-acting fail-safe output before pressurizing the system.
• Respect the explosion protection requirements in the hazardous area.
• Configure the split range, travel limits, and travel time after calibration.
