2. Load measurement complete signal
A load measurement complete signal is created when terminals
③
and
④
are opened,
(
"b" type contact
)
or the voltage level rises to logical 1. The system responds to the rising edge when the shorted terminals
are opened
(
when the level changes from "0" to "1"
)
.
●
Logical "0":
0 to 1.5 V
●
Logical "1":
3.5 to 5 V
●
Input current:
2 mA or
less
NOTE
: Use
"b" type contacts
for this signal. Since the system uses the change from a short
circuit to an open
(
ON to OFF
)
as a timing signal, you should make sure that the
terminals are shorted and then opened after the measurement is complete. When a reset
signal is input, the contacts for the load measurement complete signal should be shorted.
