The Safety Relays and sensors are maintenance-free. Nevertheless, they must be replaced after a
maximum of 20 years.
Always completely replace the sensors together with actuator.
For the tests, observe nationally applicable regulations.
Document all tests in a comprehensible manner.
Acc. to IEC TS 62046 and national regulations (e.g., EU directive 89/655 EEC amended by 95/63/EC),
tests are to be performed by competent persons in the following situations:
Prior to the initial start-up
Following modification to the machine
After longer machine downtime
Following retrofitting or reconfiguring the safety device (Safety Relay, sensors and their actuators,
etc.)
Test the effectiveness of the shutdown function in all operating modes of the machine acc. to the follow
-
ing checklist (see chapter 8.1.1 Checklist before the initial start-up ).
Document the test of the safety device (including alignment and positioning of sensors, their actuators,
Safety Relay, etc.) along with the wiring diagram of the MSI-MC3x and the data for safety and minimum
distances in a comprehensible manner.
Before they begin work, train the operating personnel on their respective tasks. The training is the
responsibility of the operating company.
Check whether the safety device (sensors, their actuators, Safety Relay, etc.) was correctly selected in
accordance with the locally applicable regulations and directives.
Attach notices in the respective national language of the operating personnel on the machine in a highly
visible location, e.g., by printing out the corresponding chapter (see chapter 8.3 To be performed daily
Check whether the safety device (sensors, their actuators, Safety Relay, etc.) is operated acc. to the
specified environmental conditions (see table 13.3).
Check whether the Safety Relay, sensor and actuator are operated according to their specified environ
-
mental conditions (see chapter 13 Technical data ). Make certain that the MSI-MC3x is protected
against overcurrent.
Perform a visual inspection for damage and test the mechanical and electrical function (see chapter 8.2
To be performed periodically by competent persons ).
Minimum requirements for the power supply unit:
Safe mains separation
At least 2 A current reserve
Not until proper monitoring of the guard is ascertained may it be integrated in the control circuit of the
system.
Make certain that, during all conversions, maintenance work and inspections, the system is securely
shut down and protected against being restarted.
Make certain that there are no people in the danger zone.
