4.7 Judging Errors from the Error Indicators
If an error occurs in the S − LINK system, the ERROR indicator indicated in the table
below lights, depending on the content of the error.

Description Steps to take
ERR1 ERR2 ERR3 ERR4
on off on off Short − circuit between D − G
note 1
If the ERR1 or ERR3 indicator lights, output of
the signal being transmitted stops, and none
of the S − LINK devices connected to the sys-
tem will operate.
Also, if a short − circuit occurs at a location far
away, there may be times when ERR1 does
not light.
Check the S − LINK signal/power line.
off off on off Error in level of signal being
transmitted
There is a possibility that the wiring length, the
configuration, or the number of configuration
devices connected to the system exceeds the
rated limit. Check the system configuration
once again.
off off off on Address has been changed/
D or G line is broken or dis-
connected/
Error in S − LINK unit for dis-
played address note 2
Check to see if the S − LINK signal/power line
is broken or disconnected, or if the address is
incorrect.
In this case, transmission signals are being
output, so the S − LINK input/output devices
operate normally.
Notes
1) This ERROR indicator lights even if the external power supply
to the S − LINK has not been turned on, but this does not
indicate a breakdown in the S − LINK control unit itself. Check
the external power supply to the S − LINK.
2) ERR4 is held, so to cancel it, one of the following is required:
turn the power supply to the FP0 off and then on again, press
the system SET button and enter the settings again, or turn
the power supply on the S − LINK side off and then on again.
