3.6 Muting Function (Only for ST4-C12EX)

The muting function is incorporated only in the ST4-C12EX. To operate the muting function you
need muting sensors (see page 60).
The muting function turns the safety function of ST4-C12EX off temporarily. When the control
output OSSD 1/2 is ON, this function allows the work piece to pass through the sensing area
without stopping the device.

DANGER!
Incorrect use of the muting function may cause accidents. Please
study the muting function carefully before you use it.
Use the muting function while the machine cycle is not in danger
mode. Maintain safety by using other measures while the muting
control is activated.
For applications where the muting function is used when a work
piece passes through, place the muting sensors at such a distance
so that personnel do not accidentally activate the muting function.
Be sure to check that the muting function is working properly
before you use it in live operation. Check the state of the muting
lamp for cleanliness, brightness, etc.
Always connect a muting lamp and use the preset muting lamp
diagnosis function (see page 74).
Install the muting lamp in a position where it can always be seen by
operators who configure or adjust the machine.
