If indicated by the user’s risk assessment, a ‘manual reset’ button (refer to EN 954-1:1996 para. 5.4)
should be included in the emergency stop system. A reset switch is required when there is limited visibility
of the danger zone from the control position. The reset switch must be positioned outside the danger
zone and in a safe position from which it may be determined that no person is within the danger zone
before resetting the safety system.
