The following table lists the conditions for sequence errors for each muting
mode.
Note All muting signals must turn OFF before the normal sequence.
Muting Mode Normal sequence Error sequence that may cause an error
Position Detection AOPD input turning OFF is detected while
muting signal 11 is ON.
AOPD input turning OFF is detected while
muting signal 11 is OFF.
Parallel Muting with 2 Sensors Muting signal 11 is detected, and then mut-
ing signal 12 is detected.
• Muting signal 12 is detected before muting
signal 11 is detected.
• Muting signals 11 and 12 are detected
simultaneously.
• AOPD turns OFF before the normal
sequence is detected.
Sequential Muting (Forward
Direction)
Muting signal 11 is detected, and then mut-
ing signal 12 is detected.
• Muting signal 12 is detected before muting
signal 11 is detected.
• Muting signals 11 and 12 are detected
simultaneously.
• AOPD turns OFF before the normal
sequence is detected.
• Muting signal 21 or 22 is detected before
muting signal 11 is detected.
• Muting signal 21 or 22 is detected before
muting signal 12 is detected.
Sequential Muting (Both Direc-
tions)
Input Sequence
Muting signal 11 is detected, and then mut-
ing signal 12 is detected.
• Muting signal 12 is detected before muting
signal 11 is detected.
• Muting signals 11 and 12 are detected
simultaneously.
• AOPD turns OFF before the normal
sequence is detected.
• Muting signal 21 or 22 is detected before
muting signal 11 is detected.
• Muting signal 21 or 22 is detected before
muting signal 12 is detected.
Output Sequence
Muting signal 22 is detected, and then mut-
ing signal 21 is detected.
• Muting signal 12 or 21 is detected before
muting signal 22 is detected.
• Muting signals 21 and 22 are detected
simultaneously.
• AOPD turns OFF before the normal
sequence is detected.
• Muting signal 11 or 12 is detected before
muting signal 21 is detected.
• Muting signal 11 or 12 is detected before
muting signal 22 is detected.
