Instructions

• When both the FR-A8AN and a plug-in option FR-A8AY are mounted, analog output function (Pr. 306 to Pr. 312) of the FR-
A8AN has precedence.
For the FR-A8AY, only digital output function (Pr. 313 to Pr. 319) is valid.
• An ammeter having larger internal impedance than the value indicated in the 1.3 Specifications on
full-scale and may not be calibrated.
• When calibrating a meter which has a small full-scale value, set the output of terminal AM2 (or AM3) to the minimum without
the meter connected. Then, connect the meter and make calibration.
Caution
 This option unit is factory-set to provide the full-scale output of 20mADC. Hence, an ammeter (14mADC or less) with a small full-scale value
may be damaged accidentally during calibration. This should be fully noted.
• Set "20%" in Pr. 307 (Pr. 311) and "100%" in Pr. 308 (Pr. 312) when calibrating Pr. 323, Pr. 324, C0 (Pr. 900), C1 (Pr. 901)
when Pr. 309 = "10 or 11 " to prevent calibration value deviation.
• When the protective function (E.1 to E.3) is activated, all the outputs are shut off.
