PT100 Activation Level 1 Protection Frequency Delay Time
Default: 60
Settings 0–6000 sec.
PT100 operation instructions
(1) Use voltage type analog input (AVI, AUI, and ACI voltage 0–10 V) and select PT100 mode.
(2) Select one of the voltage type analog inputs below: (a) AVI (Pr. 03-00=11), (b) AUI (Pr.
03-02=11), or (c) ACI (Pr. 03-01=11 and Pr. 03-29=1).
(3) When selecting Pr. 03-01 = 11 and Pr. 03-29 = 1, you must switch SW4 to 0–10V for the
external I/O board.
(4) The AFM2 outputs constant voltage or current, then Pr. 03-23 = 23. You must switch AFM2
SW2 to 0–20mA for the external I/O board, and set AFM2 output level to 45% (Pr. 03-33 =
45%) of 20 mA = 9 mA.
(5) Use Pr. 03-33 to adjust the constant voltage or constant current of the AFM2 output; the
setting range is 0–100.00%.
(6) There are two types of action levels for PT100. The diagram below shows the PT100
protecting action.
