MOUNTING BRACKET (optional)
Fig. 1 Fig. 2
An (optional) mounting bracket is available, allowing an easy and fast removal of
the receiver when not used.
In order to install the bracket first fasten the leads on the back of the case as
shown in fig.1. After fasten the bracket on the fixed support and insert the receiver
on the bracket, as depicted in fig. 2.
Do not use this solution in case of heavy vibrations.
INTERLOCKING
All command systems controlling the machine must compulsorily be interlocked,
so that only one system at a time could take control.
EXISTING SAFETY SYSTEMS
All the safety systems already installed in the controlled machine must not be
removed
STOP COMMAND ON THE RECEIVER UNIT
Receiver unit is shipped from factory with the STOP command available externally
through a 2 wires contact. Protection of the STOP command is implememented internally
by means of 2 safety contacts connected in series.
In case an external safety device is used it is possible to make available externally 2
separate contacts (4 wires) removing the "jumper" fitted serially between connectors 2 and
3 (see figure in 'Receiver units JRAEA-JRAEB').
DO NOT REMOVE the above mentioned "jumper" unless it is necessary to
connect an external safety device through 2 separated contacts (4 wires). If the
jumper is removed without connecting an external safety device the STOP circuit
can loose its safety function.
