Two
hand control device
The two hand control device is made by using two Safeballs™,
each having two internal pushbuttons. The Safeballs™
must be mounted a minimum distance between each other.
The highest safety level is achieved by connecting all
four pushbuttons to the JOKAB SAFETY JSBR4 safety relay.
The safety relay gives a dual and supervised safety function
and requires input activation within 0.5 seconds in order
to start the machine. It also checks that all four pushbuttons
have returned to their deactivated positions before a
new start is allowed.
The JSBR4 safety relay also provides a stop signal if
one or more pushbuttons are released.
One
hand control devices
Safeball™ is also a very practical method of providing
a one hand control device as it is very easy to find
and activate by the machine operator. One hand devices
should only be used when the operator cannot reach into
the hazardous area with his/her free hand or on less
dangerous machines.
To achieve the highest safety level for one hand control
the Safeball™ must be connected to the JOKAB SAFETY
RT6 safety relay.
