4-3-2 Wiring to E-STOP Input Terminals
The E-STOP input terminals are used to connect a signal input, such as an emergency stop switch, for
stopping the machine to which the SL-C is installed. The terminals are normally closed terminals, so jumpers
are placed across the terminals at the time of shipment to create a short-circuit across the terminals.
When an emergency stop switch is connected to the E-STOP input terminal, an emergency stop switch that
satisfies the following specifications must be used.
When a signal is input to the E-STOP input terminal, the OSSD turns off and the machine stops.
(For detailed requirements in addition to the following, refer to ISO13850.)
1.The emergency stop switch actuator shall be a mushroom-shaped push button or a rope type.
2.The emergency stop switch actuator shall be colored red.
3.There are positive opening operation, and the normal status of the contact is closed.
4.Resetting the emergency stop switch shall only be possible as the result of a manual action on the
emergency stop switch itself. (In other words, it is a self-tripping switch.)
5.Have a third-party certification organization (UL, etc.) verify that the emergency stop switch complies
with the regulations, standards, and laws of the country or region where the SL-R11E will be used.
In addition, when connecting one emergency stop switch to the E-STOP input terminal, the wiring is as
shown below, so refer to the following wiring.

WARNING
• Depending on how the emergency stop switch is used, the electrical articles,
regulations, standards, and laws of the country or region where the SL-C Series
and SL-R11E will be used must be complied with, so refer to all related require-
ments when using these devices.
• When no wiring is connected to the E-STOP input terminal, do not remove the
jumper (short bar) attached to the E-STOP input terminal at factory shipment.
• The SL-C Series and SL-R11E interlock states are designed to remain un-
changed even if the emergency stop switch is reset. To restart the SL-C Series
and SL-R11E, emergency stop switch reset and restart input are required, be
sure to
➮ See “4-3-1 Wiring to Start/Restart Input Terminals” (page 4-5) regarding restart
input.
