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.
The operator must be connected after the Muting
operator (Muting OUTPUT directly to the Override
INPUT). The operator permits override of the directly
connected Muting Input. Override can be activated
only if Muting is not active (INPUT=0) and at least one Muting sensor is occupied (or the light curtain is
occupied). Override ends when the light curtain and sensors are cleared and the Output switches to logical
“0” (FALSE). Override can be set to pulsed or maintained action mode.
Override with maintained action control.
This function must be activated maintaining the Override command active (OVERRIDE=1) during all
subsequent operations. However, a new Override can be activated, de-activating ad re-activating the
command. When the light curtain and sensors are cleared (gap free) or on expiry of the timeout, Override ends
without the need for further commands.
Override with pulsed action
This function is enabled activating the Override command (OVERRIDE=1).
Override ends when the light curtain and sensors are cleared (gap free) or on expiry of the timeout. The
function can be restarted only if the Override command is re-activated (OVERRIDE=1).
⇒
Otherwise, a warning is displayed in the compilation phase and in the report.
⇒
The user must adopt additional safety measures during the Override phase.
Parameters
With sensors occupied: Must be selected with “T” sequential, simultaneous muting; with “L”
muting, must not be selected.
