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.

The user may replace parts, using 
exclusively their equivalents approved by 
the manufacturer! Any modifications or 
installations of other components / devices in 
the system shall be prohibited. The SSZ control 
unit shall be the only device suitable for control 
of SSZ sensitive devices. Replacing SSZ control 
unit or pressure-sensitive devices by products 
of other vendors poses a risk of functionality 
failure or total collapse for the entire system!

No spare parts for the above-mentioned 
system. In case of any failure, replacement 
parts shall be sought from the manufacturer, 
including the control unit, the cable, the 
aluminium profile or the pressure-sensitive 
device.

In order to ensure proper functionality 
of a pressure-sensitive protective device, 
as well as its installation, adhering to the 
requirements of EN-ISO 13849-1-2 and EN ISO 
13856-1-3 : 2013-1, the technical personnel 
shall be familiar with assembly techniques, 
as well as with gear and systems, supported
