■ Descriptions of Each Level
• Protect Level
• Operation Level
• Adjustment Level

• Manual Control Level

• Initial Setting Level

• Advanced Function Setting Level

• Communications Setting Level

• In order to switch to this level, it is necessary to press the
M keys simultaneously for at least 3 seconds. This level is used to
prevent unnecessary or accidental revisions to the parameters.
The protected level is not displayed, so that no changes can be
made to parameters within this level.
• Once a power supply is connected, this level is displayed. It is
possible to switch from this level to protect level, initial setting lev-
el, and adjustment level.
• During regular operations, this level is selected. It is possible to
view process value and MV during operations, as well as viewing
and revising set values, alarm values, and upper and lower limits.
• In order to switch to this level, press the
second.
• Input in this level is used in controlling set values and shifted val-
ues. This level contains parameters used in setting up AT (auto-
tuning), communications writing enabling/ disabling, hysteresis,
multi-SP, input shift, and PID constants. It is possible to switch
from this level to the peak parameters in the initial setting level,
protect level, or operation level.
• Pressing the A key for at least 1 second in operations/ adjust-
ment level will place you in manual mode and bring you to man-
ual control level. During manual operations, nothing besides
process value/ set value/ percentage of valve opening (manual
MV) can be displayed. In manual control, with process value/ set
value/ percentage of valve opening (manual MV) displayed,
pressing the A key for at least 1 second will move you into auto-
matic mode and switch you to the operation level, displaying op-
eration level's initial data. In this mode, it is possible to perform
MV manual operations.
• To switch to this level, it is necessary to press the
eration level or adjustment level for at least 3 seconds. One sec-
ond later, the PV display will flash. This level is used for
designating input types, selecting control methods and control
times, as well as setting direct/ reverse operations and alarm
types. From this level, it is possible to switch to the advanced
function setting level or communications setting level. Press the
L
key for at least 1 second to return to operation level. Press the
L
key for less than 1 second to switch to the communications
setting level.
• In order to activate the advanced function setting level, set protect
level's initial setting/ communications protection to 0, and then in-
put the password (-169) in the input initial setting level.
• It is possible to switch from this level to the initial setting level.
• This level is used to set the display mode, event input assign-
ment, standby sequence, alarm hysteresis, and alarm delay.
• To switch to this level, press the
for less than 1 second. When using the communications function,
the conditions of communication are to be set in this level. Com-
munications with a personal computer (host computer) allows set
values to be read and written, and manipulated variables to be
monitored.
