●Muting lamp outputs: Y17 and Y20
Muting lamp outputs are used to control muting lamps.

Target safety inputs
(Terminal names)
Description of operation
Muting lamp output 1
(Y17)
Safety input 1
(X0, X1)
The output is ON, during safety input 1 is muting state by
muting input 1.
Muting lamp output 2
(Y20)
Safety input 2
(X4, X5)
The output is ON, during safety input 2 is muting state by
muting input 2.
Warning
The muting lamp outputs are not safety outputs. Do not use these to construct a safety system.
Note. Muting lamp output terminals (Y17 and Y20) detect that muting lamps are disconnected or
unconnected. If these failures are detected, the error LED displays “5” and the state changes to
the Stop state.
Note. If there is an unused muting lamp output, connect a resistor (10 kΩ, 1/4W) to the unused
terminals.
Caution
Refer to "Chapter 2 PRODUCT SPECIFICATIONS" for specifications of each input and output.
