    CERTUS Installation Manual Installation Mechanical Fastening Fix the Certus system units to a 35mm DIN rail as follows: 1. Connect the same number of “SCC” 5-pole rear panel connectors as the number of units to be installed. 2. Fix the train of connectors thus obtained to the DIN 35mm (EN 5022) rail (hooking them at the top first).

    If the CMM unit is damaged, you can replace it with a new one; having already saved all the configurations on the CMC, all you need to do is insert the CMC in the new CMM and switch on the Certus system, that will immediately load the backup configuration. In this way, the work interruptions will be minimized.
  • Page 16 Each time CMC is used, carefully check that the chosen configuration is the one that was planned for that particular system. Try again a fully functional test of the system composed of Certus plus all devices connected to it (see the TESTING the system section).

    CERTUS Installation Manual Passing Make Contact In the PASSING MAKE CONTACT operator the output follows the signal on the input. However, if this is 1 (TRUE) for longer than the set time, the output changes to 0 (FALSE). When there is an input falling edge, the timer is cleared.

  • Page 106: Delay

    CERTUS Installation Manual Delay DELAY operator applies a delay to a signal by setting the output to 1 (TRUE) after the set time, against a change in the level of the input signal. Parameters Time: The delay can be set to between 10 ms and 1093.3 s.

    CERTUS Installation Manual Muting “L” The activation of the Muting function occours following interruption of the sensors S1 and S2 beam (the order does not matter) within a time range from 2s and 5s decide by the operator. The state of the Muting ends after the liberation of the guarded opening.

If the pallet proceeds in the opposite direction the correct sequence is: S4, S3, S2, S1.

    CERTUS Installation Manual Muting “T” The MUTING operator with “T” logic performs muting of the input signal through sensor inputs S1 and S2. ⇒ Preliminary condition: The Muting cycle can only start if S1 and S2 are 0 (FALSE) and the inputs are 1 (TRUE) (barrier free).

    CERTUS Installation Manual Muting Override (max number= 16) The Override function must be used when the machine stops due to incorrect Muting activation sequences with the material obstructing the guarded opening. The function activates the OSSD outputs making it possible to remove the material that is obstructing the guarded opening.

There are two types of reset: Manual and Monitored. When Manual is selected the system only verifies the signal’s transition from 0 to 1.
