Notes
•
If 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. To cancel this error, either turn
the power supply to the FP2 off and then on again, or press the
system SET button to reset it if 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.
