Muting Starting Conditions
1. Sequence Check
Detection will be performed in order from Sensor MS11 to Sensor MS12.
Sequence errors will occur in the following cases.
• S2 is detected first.
• MS11 and MS12 are detected at the same time.
• MS21 or MS22 is ON when MS11 and MS12 are detected.
2. Synchronization Time Check
The time (T1) from when MS11 is detected until MS12 is detected must not
be greater than the maximum synchronization time. A synchronization er-
ror will occur in the following case.
• The maximum synchronization time from detecting MS11 until detect-
ing MS12 has elapsed.
Muting Ending Conditions
1. Sequence Check
• If two or more Sensors are not ON, muting is ended.
Note Muting will also end if the sensor status is not valid.
2. Maximum Time Check
• If the muting time exceeds the maximum muting time, muting is ended.
Note The time for Safety Light Current muting to turn OFF is not moni-
tored.
