4 Functions
By means of muting, the protective function of the safety sensor can be temporarily and properly sup-
pressed, e.g. if objects are to be transported through the protective field. The OSSDs of the muting con-
troller remain in the ON state in spite of interruption of one or more beams of the safety sensor.
Muting mode
The muting controller supports the following muting mode:
• Timing controlled 2-sensor muting (see chapter 4.1 "Timing controlled 2-sensor muting")
Muting timeout
Configurable time limit for the muting function (muting timeout):
• 20 seconds
• 2 minutes
• 10 minutes
• 100 hours
Muting timeout is set via the DIP switch blocks (see chapter 8 "Starting up the device - Configuration").
Muting sensors
Muting is initiated automatically and via mutually independent muting signals by muting sensors.
• Photoelectric sensors or scanning sensors can be connected to the muting controller as muting sen-
sors (see chapter 14 "Order guide and accessories").
• The state of a muting sensor is transferred on pin 4 of the connection on the muting controller.
• The muting signals of the muting sensors are debounced:
• Pickup delay: 60 ms
• Slow release: 300 ms
NOTICE
Do not use muting signal MS1 via machine interface and local socket simultaneously!
Ä
If muting signal MS1 is used via the machine interface, MS1 must not be used simultane-
ously on the local socket.
4.1 Timing controlled 2-sensor muting
Muting is initiated automatically and via two mutually independent muting signals. These signals must be
active during the entire duration of the muting operation. Muting may not be initiated by a single sensor sig-
nal, nor may it be fully initiated by software signals.
The protective function of the entire protective field is deactivated during timing controlled muting.
