IMPORTANT NOTE:

Please read carefully and thoroughly all of the

CAUTIONS, WARNINGS

on the inside back cover.

These systems are not designed for controlling clutch/brake mechanisms on mechanical power presses.

Pre-engineered panel-mounted design with air entry via a filter and regulator “FR”, or filter, regulator and lubricator “FRL”

Includes DM

Series E Double Valve with Monitoring & Memory:

a) Self-contained dynamic monitoring system requires no further valve monitoring controls,
b) Dynamic memory of abnormal function prevents unintentional reset with removal of air or electricity.

All necessary features for safety applications are included:

a) Electrical reset valve,
b) Status indicator switch for valve condition (ready-to-run) feedback.

Series E Double Valve with Monitoring:

a) Self-contained dynamic monitoring system requires no further valve monitoring controls,
b) Ready-to-run: If an abnormality clears itself upon the removal of electricity to both solenoids, it will be ready-to-run again.

It does not remember the abnormality & stay in a locked-out state until intentionally reset.

Therefore, cumulative abnormalities may go undetected,

c) Status indicator switch for valve condition (ready-to-run) feedback.
