Functional Descriptions
Muting input conditions
● The order for inputting the muting input A and B, which the muting function activates, can be set.
A = b: Effective even either comes first
A b: Effective only when the input A comes first
b A: Effective only when the input B comes first
Note: The setting is possible for each channel.
Setting of the muting lamp diagnosis function
● The muting lamp diagnosis function can be set to “effective / ineffective.” (Note)
The factory setting of this function is effective.
ON : The muting lamp diagnosis function is effective.
OFF : The muting lamp diagnosis function is ineffective.
Note: If the muting lamp diagnosis function is set to ineffective, the muting function is maintained even if the lamp blew.
Muting sensor output operation setting
● Output operation of the muting sensor can be selected.
The factory setting is NONO (Normally Open, Normally Open).
• NONO (Normally Open, Normally Open)
A muting sensor which is to be connected to the muting input A (ON with light non-received
status, ON with object approaching status and ON with object contacted status)
A muting sensor which is to be connected to the muting input B (ON with light non-received
status, ON with object approaching status and ON with object contacted status)
• NONC (Normally Open, Normally Closed)
A muting sensor which is to be connected to the muting input A (ON with light non-received
status, ON with object approaching status and ON with object contacted status)
A muting sensor which is to be connected to the muting input B (ON with light received status,
ON with object non-approaching status and ON with object non-contacted status)
3-1-7 Interlock Setting Changing Function
One condition can be selected from the following three interlock conditions. It can be set to invalid,
too. (Mode 3)
• Start / Restart interlock (Mode 0)
The SE4D series goes into interlock condition after the power is ON and when it is in the light
receiving condition.
The factory setting is Start / Restart interlock.
• Start interlock (Mode 1)
The SE4D series goes into interlock condition only when the power is ON. Once the SE4D
series is reset, it does not go into interlock condition again.
• Restart interlock (Mode 2)
The SE4D series does not go into the interlock condition when the power is ON. The SE4D
series goes into interlock condition only when the SE4D series receives the light, after the
power is ON, the control output (OSSD 1 / 2) is turned into ON once and then the SE4D series
is blocked.
