• Seismic requirements: Meets DIN/IEC 68-3-3 Class III for strong and strongest earthquakes
• Mounting orientation: No effect on performance

Installation Guide

• Verify the actuator type and confirm compatibility with double acting, fail freeze operation.
• Mount the V18345-1010521001 securely to the actuator using the standard mounting kit.
• Connect electrical wiring to the 1/2-14 NPT thread and air piping to the 1/4-18 NPT thread.
• Wire the 4…20 mA input signal and the analog feedback module as required.
• Configure signal direction, characteristic curve, tolerance band, and dead band through the operator panel.
• Check supply air pressure and confirm stable output pressure at OUT 1 before commissioning.
