GPIO Selection and Settings
Figure 116 shows the GPIO tab. Click GPIO and select the function of the three
inputs. Two of the inputs must be the muting sensors. A likely choice for the
third input is a mute dependent override function.
Figure 116 - General Purpose Input Output Selection
Click Settings IO_x to set Logic and Filter times. Figure 117 on page 134 shows
the options for the GPIO settings.
The Logic function for muting sensor is fixed at LOW Active. When an object
passes in front of the sensor, the sensor output turns OFF.
Adjust the filter times to help prevent inadvertent changes from the sensor
output from disrupting the muting process. The filter times can be adjusted
from 0…255 ms.
Click OK after adjustments are made.
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
• Increment: 10 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 ms
• Increment: 10 ms
Partial muting (user
defined)
The safety light curtain can be configured to allow muting of a specified number of lenses.
Specify the first lens and last lenses to mute. If the other lenses are blocked, the OSSD
outputs turn OFF.
