FAIL/Chart End Detecton and Output (/F1)
Item Specfcatons
FAIL output Relay output on CPU error
Relay operation Energized during normal operation and de-energized on CPU error. Non-hold operation.
Chart end detection output Stops recording and outputs a relay signal when the remaining amount of chart paper is
approx.2 cm. Also, turns ON the words CHART END on the display.
Relay operation The relay is energized when the above conditions are met. Non-hold operation.
Contact rating 250 VAC (50/60 Hz)/3 A, 250 VDC/0.1 A (for resistor load)
