EIS - Electronic Interface System Vacuum Controls

Request Product Information

Complete vacuum control and integration. Specifically designed to optimize V1000 performance. EIS allows pneumatic/electronic communication with valves to provide even more accurate and consistent control of vacuum levels. EIS lets you link valves to mill-wide DCS systems for optimum vacuum control. For the first time, you can fully integrate vacuum control into the complete papermaking process.

Four Control Solutions

Two links to existing DCS systems (E1 or E2),and two (E3 or E4) provide stand-alone, closed loop vacuum control.

E1 allows remote adjustment of vacuum setpoints. The system uses a Kadant AES custom-calibrated current-to-pressure transducer that converts an electronic 4/20mA signal from the mill control system to the proper air signal required to operate the V1000 valves.
E2 combines the E1 with a Kadant AES current-to-pressure transducer, which is pneumatically piped to the process standpipe. It requires a 4/20 mA input signal for each valve, and provides a 4/20 mA output signal that corresponds to the process vacuum range.
E3 is a stand-alone closed-loop system for mill that cannot supply a 4/20 mA signal. It consists of a V1000E2 panel and a remotely-located (typically on the tending side) single-loop PID controller panel that lets the operator view process vacuum, and easily make setpoint changes.
E4 lets mills introduce an alternative input signal into the PID control panel loop - typically a 4/20mA-process variable-like consistency measurement. It's essentially an E3 system, but with the P/I output signal connected to a process display for visual feedback of stepfoil or other control box vacuum.

Features / Benefits

Provides electronic communication with vacuum control valves - superior precision and faster response than all pneumatic valve controls
System responds immediately to even the slightest changes detected in vacuum level supply or incoming sheet consistency - sheet consistency variation is minimized
Remote vacuum setpoint adjustment - faster, easier, and safer vacuum adjustment
A single I/P panel can drive several valves - reduced system complexity and cost
Four separate models - systems can be configured for stand-alone closed-loop control, or linked directly with mill-wide process control systems.
