Explanation
• When error is generated, the LED display (flicker) is made according to
the error number setting priorities.
(The Basic model QCPU supports only the annunciator (error item No.
7).
• The Universal model QCPU sets execution/non-execution of LED
display of the error corresponding to the each priority ranking when the
error occurs.
• The setting areas for priorities are as follows:
b15
b12
b11

SD207

(Priority 11 is valid when Redundant CPU is used.)

• No display is made if "0" is set.
• In case of the Basic model QCPU, the ERR. LED turns ON when the
annunciator turns ON, if "7" has been set to either of priorities 1 to 11.
• In case of the Basic model QCPU, the ERR. LED does not turn ON
when the annumciator turns ON, if "7" has not been set to either of
priorities 1 to 11.
However, even if "0" has been set, information concerning CPU module
operation stop (including parameter settings) errors will be indicated by
the LEDs without conditions.
