Memory is set to “by signal”, the SEL1
and SEL2 terminals can be used to
select the active Setting Memory.
See “9-1. Setting Memory” on page

17 SEL2
18 COM
This is the control input signal com-
mon terminal.
o
The control input signal is isolated from the unit’s circuits by
a photocoupler.
o
Signals are input to each terminal by shorting and open-
ing with 18 COM.
A current of about 20mA results from shorting.
When using a transistor, select one with a resistance of
at least 10 V and elements that allow the flow of at least
40 mA when on.
o
You can confirm the status of the input signal on the
screen shown in “6-6. Control Input Check” on page 50.
