E-STOP
The E-STOP connector is provided to allow connection of an external EMERGENCY STOP switch into the UCC T3 system. The machine
manufacturer or product installer must perform a risk assessment to determine the requirements for emergency stopping and emergency
switching off. The UCC T3 emergency stop safety system is designed to achieve category 2 or category B implementation as selected by the
installer's risk assessment (refer to BS EN ISO13849-1:2008 para. 5.2.2).
The connection on the UCC T3 is a 9WD plug connector with the following connections:

E-STOP electrical characteristics
Any emergency stop components fitted to this connector must have the following electrical characteristics:
Emergency stop system voltage: 24 V
Emergency stop system current: 1 A
All connections to this connector should be fitted by a competent technician or engineer and all wires should be sleeved. Any emergency stop
devices added to the E‐STOP chain should meet the requirements of IEC 60947‐5‐1 ﴾Low‐voltage switchgear and control gear – Part 5‐1:
Control circuit devices and switching elements – Electromechanical control circuit devices﴿ or UL1054 ﴾Standard for special‐use switches﴿.
NOTE: If there are no additional emergency stop devices to be added to the system, connect pin 1 to pin 4, and pin 6 to pin 7 to
permit the UCC T3 emergency stop switch to function.
NOTE: If the RESET signal is not used, connect pin 6 (E-STOP A) to pin 9 (RESET).
If indicated by the user's risk assessment, a 'manual reset' button ﴾refer to BS EN ISO13849‐1:2008 para. 5.2.2.﴿ 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.
