2.12.2. Emergency Stop Sense Input (J12)
The ESTOP sense input (J12) is used to monitor the state of an external safety circuit only. This state allows
the A3200 system to report the Emergency Stop status and to facilitate restarting the system after the
Emergency Stop condition has been removed.
The response of the system to the Emergency Stop input is configurable using the FaultMask parameters.
However, this operation is not considered part of the safety circuit and is not compliant with EN ISO 13849-
1. For hardware options compliant with EN ISO 13849-1, see
W A R N I N G : The machine integrator, OEM, or end user is responsible for performing the
design, integration, and test of the safety system in accordance with the relevant safety
standards. This responsibility includes the use of safety monitoring devices, interlocks,
switches, light curtains and all other means of providing operator protection.
