Chapter 1: Overview
The SEMELEX is a self-contained, portable, multi-purpose diagnostic system for press room automation and operator
safety device analysis. The Semelex can quickly calculate machinery stopping time and determine the minimum safe
distance for safety devices including light curtains, palm buttons, E-Stop and safety mats.
The 1999SEMC Semelex II Safetimeter Test Set is field proven to accurately measure press stop time and safety
distance to verify compliance with federal and state requirements. Designed for harsh industrial environments, the unit
is portable, light weight, battery operated, and easy to use.
The Semelex Safetimeter is capable of measuring elapsed time, stop time (Ts) from 1-9999 milliseconds. It also
calculates the minimum safety distance (Ds) based on the OSHA formula, as understood by the factory, and will display
up to 999.9 inches to the nearest 0.1 inches.
The Semelex II Safetimeter Test Set consists of three components:
Safetimeter This is the “brains” of the unit, with processing electronics
that display the test results. The case is made from a highly visible yellow
plastic resin. The case is lightweight, waterproof, crushproof, dust proof and
has die cut foam inserts for the Auto-Hand and Position/ Velocity Transducer.
These tough cases are designed with an automatic purge valve, that equalizes
air pressure, a watertight silicone O-ring lid, over-molded rubber handles and
stainless-steel hardware.
Position/Velocity Transducer (P/V) This motion and position
sensor attaches to the press with its magnetic base and cable magnets.
Auto-Hand (A/H) This hand-held device is used to automatically
release a run control or press an E-Stop control on the press.
