Commissioning / Service
General:
The described pressure sensors are designed and produced according to the latest technology. All components are subject to the
strictest quality criteria during production.
Note: Please inspect the device for any damages which may have occurred during transport. If there are obvious signs of damage,
please immediately inform the transport company and Rexroth.
In spite of taking great care in preparing this document, all conceivable application cases could not be taken into account.
If information is lacking for your specific application, please contact Rexroth.
The technical specifications regarding accuracy provided in the data sheet are reached after a warming up period of approx.
10 minutes.
Safety instructions:
Prior to installation, commissioning and operation, make certain that the correct pressure measurement device was selected with
respect to measurement range, design and – based on the specific measurement conditions – parts which are in contact with
measuring materials (corrosion). Furthermore, the respective national safety regulations (eg. EN50178) are to be observed.
Failure to observe the respective regulations may result in serious bodily injury and/or property damage.
Only allow pressure measurement devices to be installed by trained and specialist personnel who are authorized by the system
owner.
Please observe the operating parameters as specified in the 'Technical data'. Operation other than that described in the this ma-
nual is considered unintended use and must, therefore, be precluded. If faults cannot be rectified, the device is to be taken out of
operation and protected against accidentally being commissioned. Repairs must only be performed by the manufacturer. Changes
and modifications to the device are not permitted.
Do not exceed the overload limit of the respective measurement range!
Connections must only be opened while in a depressurized state!
Residual measurement materials in unmounted pressure measurement devices could endanger people, the environment and
equipment. Take appropriate precautionary measures.
The suggested circuits do not imply any technical liability for the system on the part of Rexroth.
Cables to sensors must be shielded. The shield must be connected to the electronics on one side or to the machine or vehicle
ground via a low-resistance connection.
Cables to the electronics must not be routed close to other power-conducting cables in the machine or vehicle.
A sufficiently large distance to radio systems must be maintained.
All connectors must be unplugged from the electronics during electric welding operations.
Service:
PR2 pressure sensors are maintenance-free!
