STEP 3: INSTALL CABLE SUPPORTS (EYEBOLTS)
WARNING
IMPROPER OPERATION
•
Do not allow excessive side loads to occur that could
bend the switch actuator shaft so as to defeat the
broken cable detection.
Failure to comply with these instructions could result
in death or serious injury.
NOTICE
•
The first cable support should be in line with, and no
farther than, 0,46 m [18 in] from the end of the actuator
shaft.
•
When changing the actuating cable direction, i.e.,
around a corner, ensure the cable runs freely through a
pulley or cable supports.
A.
Ensure you have cable supports to fit the cable.
B.
Install a cable support as close to the end of the actuator
shaft as possible without interfering with the switch
operation.
C.
Install the cable supports at intervals of no greater than
2,4 m [8 ft] along the cable span.
D.
Thread the cable through the cable supports.
STEP 4: INSTALL CABLE TERMINATION
NOTICE
•
With an endspring installed, the switch will operate
satisfactorily over a temperature change of
±17 °C [±30 °F] up to a typical length of 76 m [250 ft].
Without an endspring installed, the temperature change
allowed is ±8 °C [±15 °F].
•
In order to comply with EN418, install a cable pull switch
at each end of the cable or an endspring at the opposite
end of the cable from the switch.
A.
RECOMMENDED: Install an endspring for applications
with temperature variations > ±8 °C [15 °F]:
• Ensure you have the following:
− Thimbles to fit all terminations.
− Cable clamps to fit all terminations.
− Endspring to fit all terminations.
•
Install an endspring at the end of the cable opposite
the switch in the same manner as Steps 2.C and
2.D.
• Attach the endspring to a fixed support.
B.
Secure the cable end to a fixed support:
• Ensure you have the following:
− Thimbles to fit all terminations.
− Cable clamps to fit all terminations.
− Fixed support to fit all terminations.
•
Attach the cable end to a fixed support in the same
manner as Steps 2.C and 2.D.
STEP 5: ADJUST CABLE TENSION
A.
Tighten the turnbuckle until the tension indicator is in the
middle of the indicator window.
B.
Tighten the turnbuckle locknuts.
C.
Periodically check and adjust the cable tension.

STEP 6: VERIFY INSTALLATION BY PERFORMING
FUNCTIONAL TESTS
CAUTION
SWITCH DAMAGE
•
Do not attempt to rotate the reset knob from OFF to RUN
unless the switch is under proper tension.
Failure to comply with these instructions may result in
product damage.
A.
Ensure the cable actuates freely. Ensure the installation
elements are not subject to mechanical damage due to
positioning or location.
B.
Turn the reset knob to RUN.
C.
PULLED CABLE STATE: Pull the cable. Ensure the
reset knob rotates to OFF.
D.
Turn the reset knob to RUN.
E.
SLACKENED CABLE STATE: Unhook the J-hook
turnbuckle. Ensure the reset knob rotates to OFF.
F.
Reattach the J-hook turnbuckle and turn the reset knob
to RUN.
