5 Resetting the safety-related device parameters
The measuring system may be destroyed or damaged or its function be
impaired by penetration of foreign bodies and ingress of moisture!
Firmly
close the access to the address switches with the screw plug
after the settings have been made.
Use the two HEX rotary switches SW1 and SW2 for resetting the device parameters. See Figure 8 on
Page 30 for details on the position and assignment of the HEX rotary switches.
The device parameters can only be reset if no IO connection is active.
Procedure:
1. Unscrew the screw plug
2. Condition 1; at least one switch or both switches are set to ≠ 0:
In this case both switches must be set to 0
-> wait for feedback under point 3
Condition 2; both switches are set to 0:
In this case, set at least one switch temporary to ≠ 0, then set both switches to 0
-> wait for feedback under point 3
3. Wait 3 s, the green NET- and green MODULE-status - LEDs flash alternately with 2 Hz
4. Set switch SW2 to 5 and switch SW1 to 2, corresponds to 0x52 = “R” (RESET)
5. Wait 3 s, the green NET- and green MODULE-status - LEDs flash alternately with 2 Hz
6. Set both switches to 0
7. Now, the safety-related configuration is reset, the TUNID and SCID are deleted and the ownership
assignment of the measuring system/originator is cancelled.
8. The measuring system reboots to apply the settings
9. The process is complete, and the screw plug can be screwed back in again
Resetting via the network:
Alternatively, also you can use the Safety Supervisor Object 0x39 to reset the device
parameters. To do so, use the Service Code 0x54 to trigger a so-called Safety Reset of Type 1
or 2.
Ensured the configuration is not locked as a precaution against changes when executing this
command. The Password and the TUNID of the measuring system are required to prevent an
unintentional deletion.
In contrast to a Type 1 Safety Reset, a Type 2 Safety Reset allows the selection of which parameters
will not be reset, e.g. the password.
