Manual reset for SSZ-RZ4B control unit
The SSZ-RZ4B control unit is provided with automatic or manual
reset functions. Regarding the automatic reset function, the
functions are the same as in the SSS-RZ4 control unit. In case of
manual reset operation of reset button has no effect on output of
output signal switching device as long as forcepresent on sensor.
The output of output signal switching device remains in OFF state
. After removing the actuating force from sensor, signal switching
device remains in OFF state even though reset signal still present.
When releasing of reset button has no effect on output of output
signal switching device.
Reset is achieved after another operation of reset button without
actuating force on the sensor.
The SSZ-RZ4B is designed exclusively for use with safety bumper!
An SSZ-safety bumper is most often used to protect driverless
vehickles. The use of an SSZ-RZ4B control unit protects against
automatic movement, which may occur after incidental bridging
or failure of the reset function with a simultaneous release of
the bumper.
