Connections

When used as a two-hand device, Safeball is designed for operation together with the safety relay JSBR4 from
ABB/Jokab Safety. This connection can achieve the highest safety level according to EN 574. To achieve the
highest safety level for a two-hand device, dual supervised safety function and simultaneous actuation of the two
Safeballs within 0.5 seconds is required (PL e according to EN ISO 13849-1). For further details, see "Installation
and maintenance" below.
NB: For specific Pluto safety PLC connection examples, refer to Pluto instruction manual.
Caution! Use of any other safety relay or supervision unit may result in a lower safety level and/or the
voltage/current limitations of the JSTD1 switches being exceeded. This may invalidate warranty conditions.
Warning! If the two-hand device is connected to another control unit, it is extremely important to analyse and
determine the safety level of the complete system. The achieved safety level is a combination of the safety relay
and the Safeballs, and must be checked for any combination of operation.
