Remedy 

Control output (OSSD 1/2) short-circuits 
with +V or 0V. 

 

The PNP/NPN settings of the output 
polarity selection switch and the control 
output (OSSD 1/2) do not match. 

Check the output polarity selection switch. 
Wire the control output (OSSD 1/2) wires 
correctly (see page 36). 

1 

Output circuit error. 

Output circuit is damaged. 
Replace the ST4-C12EX.

 

Excessive incoming current flows in the 
control output (OSSD 1/2). 

Current value should be within the specified 
control output (OSSD 1/2). 
For details, see "Specifications, Controller 
ST4-C12EX" on page 90. 

Control output (OSSD 1/2) short-circuits 
with +V or 0V. 

Wire the control output (OSSD 1/2) wires 
correctly (see page 36).For details, refer to 
Wiring (see page 36). 

The PNP/NPN settings of the output 
polarity selection switch and the control 
output (OSSD 1/2) do not match.

well. 
If the error could not be resolved, contact our 
office.

 

Muting lamp terminals short-circuit. 

Muting lamp output short-circuits with 
other I/O wires. 

Wire the muting lamp correctly (see page 36). 

Excessive incoming current flows in the 
muting output. 

Current value should be within the specification 
of muting lamp.
