13. ERROR ADDRESS DISPLAY
In case Error 4 indicator (ER4) lights up, it is possible to display the addresses of all the
S-LINK units where the error occurs by the following procedure.
However, in case of a multi-channel S-LINK * *
(Valid only for devices having the mark)
` * ; {|}~^ !"#$%
If, by mistake, the system set button is pressed when the mode switch (MODE) is set to “RUN,”
the addresses are recognized in that condition, and the fault location cannot be found.
1. When Error 4 occurs, set the mode switch to “CHK.”
The smallest address of the S-LINK units where the error occurs blinks in the address dis-
play.
2. Press the system set button.
The addresses of the S-LINK units where the error occurs blink in the address display, suc-
cessively, in the ascending order. However, for the multi-channel S-LINK units, only the set
If the system set button is pressed after the last address of the S-LINK units where the error
occurs is displayed, the smallest address of the S-LINK units where the error occurs blinks
once again.
By pressing the system set button continuously for some time, the addresses can be made
to blink successively.
3. After checking the error addresses, make sure to set the mode switch to “RUN.”
The address display returns to the normal error address display.
In case the mode switch (MODE) is set to “CHK.,” cable disconnection is not detected, and the
address causing this fault cannot be displayed even if there is a cable disconnection.
14. ERROR INDICATORS
The error indicators light up as per the faults given below.
ER1 (Error 1): Short-circuit between D and G (ER3 also lights up.)
ER3 (Error 3): Abnormal voltage level between D and G.
ER4 (Error 4): Disconnection of D or G line / Fault in connected
S-LINK unit

Notes: 1) Although the protection circuit works in the case of a short-circuit between D-G or between D-24V,
there is no protection against a short-circuit between G-24V and between 0-24V. Hence, take care
that a short-circuit between G-24V or 0V-24V shall cause a breakdown.
Further, ER1 may not light up if the short-circuit is at a long distance from the controller.
2) When ER1, ER3 light up, all the connected S-LINK units do not operate since the transmission sig-
nal output is stopped.
3) Error 3 may also occur if the wiring length, system construction or the number of connected devices
exceeds the regulations, etc.
4) When ER4 lights up, since the transmission signal is output, the S-LINK units operate, except for
the units where an error occurs due to D or G line disconnection or damage of S-LINK units them-
selves.
