1.7FAIL/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.

Chart End Output

When the remaining amount of chart paper falls to approximately 2 cm, recording is stopped, and the relay contact signal (1 relay) is output. The relay is energized in this case. This relay behavior cannot be changed.
