What To Do If An Error Occurs
7.1
Judging Errors From the Error Indicators
7.1.2
ERR1 and ERR3 are Lighted
Lighted
The S−LINK main and local power supplies (the power supply between D − G line) are
off, or the power supplies were turned on in the wrong sequence.
Check to make sure that the power supplies were turned on in the appropriate sequence.
See section "5.1 Starting Operation".
Turn off the S−LINK main and local power supplies (the power supply between D − G
line) and the power supply of FP2, eliminate the cause of the problem, and turn the
power supplies on again.
7.1.3
ERR4 is Lighted
Lighted
There is a broken or disconnected wire in the S−LINK, or there is an error in an S−LINK
device. If this happens, set the RUN/CHK. selector switch to the "CHK." position, and
press the system SET button. This displays the address of the S−LINK I/O device where
the error occurred in the address display window (if errors have occurred at multiple
addresses, the display changes sequentially each time the system SET button is
pressed). This error display is retained. Turn off the S−LINK main and local power
supplies (the power supply between D − G line), and repair the broken or disconnected
wire, or eliminate the problem with the input/output unit. Then turn on the S−LINK main
and local power supplies (the power supply between D − G line).
