• Position detection
• Parallel Muting with 2 Sensors
• Sequential Muting in Forward Direction
• Sequential Muting in Both Directions
30 ms to 3 s in 10-ms increments (See note 2.)
• Dual Channel Equivalent (NC/NC)
• Dual Channel Complementary (NC/NO)
A discrepancy time check will not be performed if 0 is set.
• Single Channel
• Dual Channel Equivalent (NO/NO)
• Dual Channel Complementary (NC/NO)
• Not used.
10 to 500 ms in 10-ms increments (See note 2.)
A discrepancy time check will not be performed if 0 is set.
500 ms to 127.5 s in 500-ms increments
The muting time will be unlimited if 0 is set.
500 ms to 127.5 s in 500-ms increments
The muting time will be unlimited if 0 is set.
(1) The Muting Signals are set according to the Muting Mode.
(2) The timer SV must be longer than the cycle time.
(3) Sets the time between Muting Signal 11 and Muting Signal 12 or between
Muting Signal 21 and Muting Signal 22.
The following outputs can also be used in programming. To enable any of
these optional outputs, select the check box on the Output Point Tab Page of
the function block properties dialog box.
• Override Status
• Synchronization Error
• Sequence Error
• Discrepancy Error (AOPD)
• Discrepancy Error (Override)
A Fault Present output can also be used in programming.
To enable this output, select the Fault Present check box on Output Point Tab
Page of the function block properties dialog box.
A synchronization error can be detected in any mode other than Position
Detection Mode.
A synchronization error will occur and Synchronization Error will turn ON if the
time difference between input signals for the muting signals (i.e., muting sen-
sors) exceeds the synchronization time that has been set. If the AOPD inputs
turns OFF (i.e., if the Safety Light Curtain is obstructed) while there is a syn-
chronization error, the Output Enable signal will turn OFF. Fault Present will
turn ON at the following times.
• When AOPD input turns OFF.
