Figure 121 - Muting Settings
GPIO Selection and Settings
With the muting settings established, the General Purpose Input and Output
(GPIO) must be set. Click the GPIO tab.
Figure 122 on page 137 highlights three sections of the GPIO settings:
1. The connection plug-in has three wiring connections that can be used as
input or output. The I/O are available on connector pins 1, 4, and 8.
2. The cascading plug-in has five wiring connections. Three can be used as
input or output, and two can only be used as inputs. The I/O are available
on connector pins 4, 8, 1, 5, and 6.
Table 61 - Muting Settings
Setting Description
Muting type This setting is a read-only field, setup by the Configuration tab.
Maximum muting time This setting is the maximum time that the material can occupy the light curtain.
Activation time
between muting
sensors T(sens)
Specifies the maximum muting time between sensors. This setting is the time in which the
object must block both sensors on either side of the safety light curtain. If the time is
exceeded, the muting timing error becomes active, and the light is not be muted. If the
object then blocks the second sensor, the muting sequence error becomes active. The
object must be removed from the sensors.
Light curtain
interruption
monitored (T(espe)
If set to OFF, the time from the start of muting to when the object blocks the safety light
curtain is not used in the muting sequence.
If set to ON, specify the time that the light curtain must be interrupted after muting starts.
If the time is exceeded, the OSSD outputs turn OFF.
Muting signal
activation delay time
Specifies a delay before muting becomes activated.
• Max setting: 2550 ms
• Default setting: 80 ms
• Min setting: 0 ms
Muting signal
deactivation delay
time
Specifies a delay before muting becomes de-activated.
• Max setting: 2550 ms
• Default setting: 50 ms
• Min setting: 0 ms
Muting dependent
override (MDO)
Specifies the duration of the muting dependent override signal. Use this function to force
the OSSD outputs ON after a muting error has occurred. The override signal becomes
active on the trailing edge.
• Max setting: 1275 s
• Min setting: 0 s
Partial muting (user
defined)
The light can be configured to allow muting to a specified number of lenses. Specify the
first lens and last lenses that are muted. If the other lenses are blocked, the OSSD outputs
turn OFF.
