SL-V-M-NO2-E
 Wiring for muting device
The input circuit for muting input 1 and 2 is as follows.
 Muting lamp wiring
 Limitations
 Muting device
• The muting device output must be N.O. (normal open).
• A PNP output muting device is required when using the PNP output type cable and an NPN output
muting device is required when using the NPN output type cable. The muting device must be capa-
ble of 2 to 3 mA current.
• Do not use one muting device with multiple outputs in place of two or more muting devices. (Only
one output per one muting device must be used.)
• If the muting device has a timer function that can adjust the output timing, do not use that function.
 Muting lamp
When using the muting lamp, it must meet the following conditions.
For an incandescent lamp : rated 24 V DC, 1 to 7 W
For LED indicator : rated current consumption must be 10 to 300 mA.
If the incandescent lamp burns out, or if the lamp used does not meet the above conditions, the state
information output shows a muting lamp error.
