Description
The 2CPS Cable Pull Safety Switch provides readily accessible emergency stop
over a long, linear distance. It is a cost- effective means of providing this emergency
stop signal compared to multiple emergency stop push buttons. (Cable Pull Safety
Switches are not, however, to be used as a means of personnel safeguarding.
They may be used to prevent further injury or damage to equipment when used for
emergency stop signaling.)
The 2CPS Series Cable Pull Safety Switch is designed to provide emergency stop
protection for exposed conveyor lines. The internal mechanism latches on both
slackened cable (push) and pulled cable. This capability enhances productivity by
eliminating nuisance stops due to variations in temperature, stretch of cable over
time, and other application variables.
A line in the midpoint of the cable tension window indicates proper cable tension,
providing easy and intuitive set-up. The direct acting switch contacts are held
closed when the actuating cable is under proper tension and the reset knob is set
to RUN. When the actuating cable is pulled, slackened or broken, a cam positively
opens the NC (Normally Closed) switch contacts. The snap action, trip operation
causes the switch contacts to change state and mechanically latch almost
simultaneously when the cable is pulled, slackened or broken. The NC switch
contacts remain open until the 2CPS is reset by properly tensioning the cable and
manually rotating the reset knob.
When the direct acting switch contacts open, the auxiliary contacts also actuate
(open contacts close and closed contacts open). The auxiliary contacts are
electrically isolated from the direct acting switch contacts. These NO (Normally
Open) contacts may be used for monitoring or signaling.
The 2CPS complies with: Low Voltage Directive 73/23/EEC, as amended by
directive 93/68/EEC; Machinery Directive 98/37/EEC only as the directives relate to
the components being used in a safety function; IEC/EN60947
-1; IEC/EN60947
