1 General
This manual contains important information for the safe and compliant use of the CANopen strain link and
must be read before initial start-up.
It was created for personnel trained and qualified in handling electrical equipment.
There are also a short introduction with definitions of CANopen terms and useful notes for properly operating
the strain link.
1.1 Safety instructions
•
The strain sensor is a compact, extremely sensitive precision measuring instrument. It is used
exclusively to measure strains with respect to tension and compression, to process and to supply
measured values as CANopen signals for the downstream device. The strain sensor must only be
used for this purpose.
•
Correct and safe operation requires proper transport, storage, mounting and careful operation and
maintenance.
•
Only a specialist may install and mount the strain sensor.
•
Check all electrical connections before using the system for the first time.
•
When using the sensors, obey all applicable safety and accident prevention regulations.
•
Safety measures must be put in place, both in terms of hardware and software, so that a broken line
does not result in undefined states of the automation equipment.
•
In the case of systems where a malfunction may cause great damage to property or even to
personnel, safety measures must be put in place that ensure a safe operating state in the event of a
malfunction. For example, limit switches or mechanical interlocks may be used.
•
You must not operate the strain sensor outside the specifications (see the data sheet).
•
Do not make any mechanical or electrical changes to the sensor.
•
Despite the rugged housing, the strain link must not be subjected to any hard impacts.
•
Avoid static and dynamic overstrains exceeding 200% of the nominal range.
1.2 Mounting and initial start-up
•
For information on mounting and connection to the measuring system, refer to the mounting
instructions supplied with the sensor.
•
Only perform wiring tasks when no power is applied.
•
Do not attach or remove electrical connections that are under power.
•
Install the entire system to maximize EMC. The installation environment and the cabling affect the
EMC of the strain link. Install the device and the power line separated from one another and at a
great distance from lines with high noise levels.
•
Connect the strain link to protective ground and use shielded cables. Bond the cable braid to the
cable screw fitting.
