· Connect event inputs 1 and 2 (EV1/2) to terminal Nos.18 to 20, and event
events 3 and 4 (EV3/4) to terminal Nos.24 to 26. However, note that ter-
minal Nos.18 to 20 cannot be used on controllers having a communica-
tions function.
· Connect the event inputs as follows:

Terminals 18 and 24 (COM) are connected internally.
· Use event inputs under the following conditions:
Contact input ON: 1 k

No-contact input ON: residual voltage 1.5 V max.,
OFF: leakage current 0.1 mA max.
· Polarities during no-contact input are as follows:

· Transfer output specifications are as follows:4 to 20 mA,
Permissible load impedance: 600
W max.,
Resolution: Approx. 2600
· Terminal Nos.18 to 20, 31 and 32 can be used only on controllers having
a communications units (E53-AK01/02/03).
· For details on wiring, see Chapter 6, Using the Communications Func-
tion.
