E-Stop Reset
E-Stop and Latch Reset
Following the pulling of the rope or the pressing of the E-stop button (model RP-LS42F-
75LE), the latch must be reset. The procedure differs slightly between the two models.
See Figure 6.
Models RP-LS42F-75L and RP-LS42F-75LF: Pull the blue reset button; the arrows
should then be centered in the tensioning indicator window.
Model RP-LS42F-75LE: The E-stop can be reset only when proper tension is indicated.
Turn the yellow knob clockwise until the blue arrow is in the “I” position (indicating that
the latch has been reset). The latch should make an audible click when reset.
Maintenance
Each rope pull emergency stop installation should be tested for proper machine
shutdown response at each shift change or machine setup by a Designated Person*.
In addition, a Qualified Person* should check for proper rope tension, and adjust as
needed, on a periodic schedule determined by the user, based upon severity of the
operating environment and the frequency of switch actuations.
The pulleys and other moving parts associated with the rope should be periodically
lubricated. If inspection reveals dirt on the rope pull switch or rope assembly, the dirt
must be cleaned off and its cause must be eliminated. Replace the rope pull switch
and/or rope assembly when any parts (including contacts) or assemblies are found to be
damaged, broken, deformed, or badly worn.
The rope pull switch and rope assembly should be replaced at specified intervals based
upon the environment and operating conditions. Replacement of the rope pull switch and
rope assembly should be considered after no more than 500,000 operations. Always
test the control system for proper functioning under machine control conditions after
maintenance or replacement of the rope pull switch.
* A Designated Person is identified in writing by the employer as being appropriately trained to perform
a specified checkout procedure. A Qualified Person possesses a recognized degree or certificate
or has extensive knowledge, training, and experience to be able to solve problems relating to the
emergency stop rope pull switch installation.
