WARNING
IMPROPER INSTALLATION
•
Consult with local safety agencies and their
requirements when designing a machine control link,
interface and all control elements that affect safety.
•
Strictly adhere to all installation instructions.
Failure to comply with these instructions could result
in death or serious injury.
WARNING
IMPROPER USE
•
Use the 1CPS 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 1CPS 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 1CPS 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 1CPS is capable of operating with a typical cable
span of 76 m [250 ft] in an environment with a
temperature change of ±17 ºC [±30 ºF] if an endspring is
used. (See Step 4 for more information.) Longer cable
spans are possible depending upon temperature change
and installation.
•
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 1CPS 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.
•
Hardware packets are available separately (see Table 3
on page 11).

STEP 1: MOUNT, WIRE AND SEAL SWITCH
WARNING
IMPROPER OPERATION
•
Ensure no barriers or physical obstructions prevent the
operator from actuating the 1CPS Cable Pull Safety
Switch.
Failure to comply with these instructions could result
in death or serious injury.
A. Refer to pages 12-16 for:
•
Specifications (Table 4).
•
Mounting dimensions (Figure 1).
•
Wiring configurations and travel distances (Figures 2
and 3).
•
Installation drawings (Figure 4).
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 is at
proper tension and the reset knob is in the RUN position.
D. Remove the cover plate.
E. Wire the switch (use 90 °C wire when the ambient
temperature is over 75 °C):
•
Connect 3,5 mm2 (12 AWG) or smaller stranded or
solid wire to the terminals.
•
Torque switch terminal screws and ground screw to
1,0 N m–1,8 N m [9 in lb–16 in lb].
F. OPTIONAL: Wire the LED indicator. For dc indicators,
the positive lead wire is red and the negative leadwire is
black. (There is no polarity requirement for ac indicators.)
G. Seal the conduit opening according to the instructions in
PK 80112 (included).
H. Reassemble the cover plate.
STEP 2: INSTALL J-HOOK TURNBUCKLE AND
ACTUATING CABLE
A. Ensure you have the following (available separately, see
Table 3 on page 11):
•
Red plastic-coated aircraft cable 3,18 mm [1/8 in]
diameter to 4,76 mm [3/16 in] diameter in desired
length. (See Step 4 for more information.)
•
J-hook turnbuckle with locknuts.
•
Thimbles to fit all terminations.
•
Cable clamps to fit all terminations.
B. Attach the hook end of the J-hook turnbuckle to the
actuator.
C. Attach the eye end of the J-hook turnbuckle to the cable
using one thimble and one cable clamp by fitting the
cable in the thimble groove and placing the cable clamp
as close to the thimble as possible.
D. Tighten the cable clamp according to the manufacturer's
instructions. (The torque for the cable clamp in the
separate accessory packet is 7,3 N m–9,0 N m [65 in lb–
79 in lb].)
