WARNING
IF USED IN APPLICATIONS CONCERNING HUMAN
SAFETY
• Only use NC direct opening ("positive opening"/"positive
break") contacts, identified by the symbol
• Do NOT use flexible/adjustable actuators. Only use
actuators designed for safety applications.
• Do NOT defeat, tamper, remove, or bypass this switch.
• Hazardous voltage, disconnect power before servicing.
• Strictly adhere to all installation and maintenance
instructions.
• Consult with local safety agencies and their requirements
when designing a machine-control link, interface and all
control elements that affect safety.
Failure to comply with these instructions could result
in death or serious injury.
WARNING
IMPROPER USE
• Use the 2CPS Cable Pull Safety Switch in emergency
stop applications only. Do not use in general production
stop applications.
Failure to comply with these instructions could result
in death or serious injury.
WARNING
IMPROPER SYSTEM PERFORMANCE
• The 2CPS Cable Pull Safety Switch provides only the
front end switching/sensing function. The machine, its
external machine interfaces, and the safety monitoring of
the machine and its interfaces, are the responsibility of
the machine safety control system.
• The user is SOLELY RESPONSIBLE for determining the
appropriate level of risk.
• The 2CPS Cable Pull Safety Switch must be installed in
a fashion that complies with all codes and standards that
are applicable to the particular application of the device.
EN 1050 and ANSI TR3 Risk Assessment and Risk
Reduction provide assistance on how to perform risk
assessment.
Failure to comply with these instructions could result
in death or serious injury.
GENERAL INFORMATION
• The 2CPS is available in either single actuator or dual
actuator versions. The maximum cable length in a single
direction is 76 m [250 ft] for a combined length of 152 m
[500 ft] in dual directions.
Sensing and Productivity Solutions
• 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.
• A removable contact block version is available for robust
and easy termination.
• Hardware packets are available separately (see Table 1
on page 13).
STEP 1: MOUNT, WIRE AND SEAL SWITCH
WARNING
IMPROPER OPERATION
• Locate the 2CPS such that the installed cable is visible
from the 2CPS reset OR inspect the length of the cable
whenever a stop is signaled.
• Ensure no barriers or physical obstructions prevent the
operator from actuating the 2CPS Cable Pull Safety
Switch.
Failure to comply with these instructions could result
in death or serious injury.
A. Refer to pages 14-19 for:
• Specifications (Table 2).
• Mounting dimensions (Figure 1).
• Wiring configurations and travel distances Figure 2).
• Installation drawings (Figures 3, 4, 5).
B. Mount switch using four M6, 1/4-28 UNF or 1/4-20 UNC
screws or bolts. Torque:
• M6 to 6,1 N m–7,5 N m [54 in lb–66 in lb].
• 1/4-28 UNF to 8,6 N m–10,4 N m [76 in lb–92 in lb].
• 1/4-20 UNC to 7,3 N m–9,0 N m [65 in lb–79 in lb].
C. Refer to the circuit diagram on the switch cover. The
diagram depicts the switch contacts when the cable(s) is
(are) at proper tension and the reset knob is in the RUN
position.
D. Remove the cover plate.
