E-STOP electrical characteristics
A manual reset button (refer to BS EN ISO13849-1:2015 (or current version) para. 5.2.2.) shall be included in the emergency stop system
when required by the user's risk assessment. A reset switch may be needed when there is limited visibility of the danger zone from the
machine's control position.
Reset switches must be located with full visibility of the danger zone and shall be sited outside the danger zone.
NOTE: If no additional emergency stop devices are to be added to the system then a bypass plug is required for the SPA3
emergency stop system to function.
All connections to the bypass plug shall be fitted by an electrically competent person and all wires are to be sleeved.
Any emergency stop device added to the E‐STOP chain must have an electrical rating of at least 24 V 300 mA and meet the requirements of
BS EN ISO 13850:2015 (or current version).
The emergency stop device shall have direct opening action with mechanical latching. The emergency stop devices shall comply with BS EN
60947-5-5:1998+A2:2017 (or current version).
CAUTION: It is strongly recommended that the CMM manufacturer or retrofitter includes a periodic test of the emergency stop
(and associated reset switch, if fitted) in the maintenance instructions.
Dual SPA3 installations
Dual SPA3 installations use the same connection above, however the installation requires a special emergency stop link cable (Renishaw part
number A-5623-0095). This is supplied in the 6-axis SPA3 kit.
This cable allows the emergency stop system to operate both SPA3 units. The cable ends of this cable are marked with their function. The
SPA3 containing the MCU must have the cable end marked 'master' plugged into its external E-STOP connector, whilst the cable end marked
'slave' must be connected to the other SPA3.
