FAIL/Chart End Detection and Output Function
(/F1 Option)
FAIL Output
When a failure occurs in the CPU of the recorder, a relay contact signal (1 signal) is
output. The relay is energized when the CPU is normal and de-energizes when a CPU
failure occurs. Therefore, relay output is carried out also when the power is turned OFF
(including a power failure). This relay behavior cannot be changed.

case. This relay behavior cannot be changed.
