Outline of Operation Procedure
Key Operation
In the following descriptions, all the parameters are introduced in the display sequence. Some parameters may not be displayed depending on the
protection settings and operating conditions.
Note:
Of these levels, the initial setting level, communications setting level, and advanced function setting level can be used only when operation
has stopped. Control output is stopped when these three levels are selected. When switched back to the operation level from one of these
levels, operation will start.
Description of Each Level
Operation Level
This level is displayed when you turn the power ON. You can move
to the protect level, initial setting level, and adjustment level from
this level.
Normally, select this level during operation.
During operation, the present value, set value, totalizing count
value, and setting number of SV-bank can be monitored using the
Key.
Adjustment Level
To select this level, press the
ond.
This level is for entering set value (SV 0 to 3) for operation. This
level contains parameters for communications writing enable/dis-
able, set value of SV-bank, and cycle time (timer Z mode).
You can move to the top parameter of the operation level, protect
level, or initial setting level from here.
Initial Setting Level
Key once for less than one sec-
To select this level, press the
the operation level or adjustment level.
This level is for selecting the function, input mode, time range, timer
mode, output mode, output time, counting speed, input signal
width, decimal point position, prescale value, and rising/falling edge
for input signal.
Key for at least three seconds in
You can move to the advanced function setting level or communica-
tions setting level from this initial setting level. To return to the oper-
ation level, press the
Key for at least one second. To move to
the communications setting level, press the
than one second.
Protect Level
key once for less
To select this level, simultaneously press the
for at least three seconds (default value). This level is to prevent
unwanted or accidental modification of parameters. Protected lev-
els will not be displayed, and so the parameters in that level cannot
be modified.
Communications Setting Level
and
Keys
To select this level, press the
ond in the initial setting level. When the communications function is
used, set the communications conditions in this level. Communicat-
ing with a personal computer (host computer) allows set values to
be read and written.
Advanced Function Setting Level
To select this level, you must change the initial settings/communica-
tions protection setting in the protect level to
“
0
”
and then enter the
password (
“
169
”
) in the initial setting level.
This level is for initializing settings, enabling SV-bank and totalizing
counter use, setting display auto-return time, and move- to-protect-
level time.
You can move to the initial setting level from this level.
