1.1: Safetimeter Switches and Connectors
NOTE: With the Safetimeter ON and plugged in, the battery charges at a lower rate.
The Series 1999 Semelex II Safetimeter is a self-contained, portable electronic stop
time meter 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 four components:
Safetimeter
This is the “brains” of the unit, with processing electronics
that display the test results.
Position/Velocity (P/V) This motion and position sensor attaches to the press with
Transducer
its 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.
Auto-Flag (A/F)
This assembly is attached to the Auto-Hand to test presses
equipped with electronic guards, i.e. photoelectric barrier
guards (light curtains) or capacitance type guards (conduit
rail sensors).
Option:
Manual Start Switches These two switches plug into the MANUAL START jack on the
Safetimeter panel and are used to manually start the
Safetimeter timing.
Option:
Remote Tachometer
The tachometer replaces the P/V Transducer and Auto-Hand
with Base
when testing high speed or continuous stroke presses that
can’t stop within one stroke. With the wheel attachment, it
can be used to test conveyors or indexing tables.
