Fuse
A 8A-tubular fuse of 5 mm x 20 mm is used (provided as an accessory).
For the replacement, use a UL/CSA-approved time-lag type fuse.
Transmission indicator (SEND)
It blinks during communicating I/O data between each S-LINK device on the S-LINK system.
It is synchronized with the communication frames, so that the blinking cycle gets slow as the number of
total I/O points is large.
ERROR indicators
These light if an error occurs in the S-LINK system.
ERR1 (Error 1): Short circuit between D-G line.
ERR3 (Error 3): Abnormal voltage level between D-G line.
ERR4 (Error 4): Broken wire or I/O S-LINK device error
Note:
•
If ERR1 (Error 1) lights (there is little possibility that ERR1 (Error 1) occurs by itself), the protective
function which guards against a short-circuit between D and G has been activated.
To cancel the protective function, turn off the power supply to the S-LINK, and then repair the cause of
the short-circuit. (The short-circuit protective function is maintained as long as the power supply to the
S-LINK is on.)
•
If the power supply to the S-LINK is turned off, ERR1 (Error 1) and ERR3 (Error 3) light.
•
ERR4 (Error 4) is maintained after repairing. To cancel this error, either turn the power supply to the
FP

off and then on again, or press the SET switch to reset it when the RUN/CHK. selector switch is
set to the RUN position, or turn the power supply to the S-LINK off and then on again.
•
If the signal line is broken or the power supply to the booster is cut off, errors occur on more than one
I/O S-LINK devices.
ADDRESS display (2-digit hexadecimal display)
This displays the transmission status, the number of connected S-LINK devices, and the addresses of
the various S-LINK devices. (Refer to “
RUN/CHK. selector switch” and “ SET switch”.
During normal transmission:
The “
” shaped character rotates in the clockwise direction.
If an error occurs:
This displays an abnormal address number. In case faults occur on several
I/O S-LINK devices, the decimal pints light up, and the smallest error address
of the S-LINK device which the error occurs is displayed.
