• To move the mode at this level, simultaneously press the
keys for at least three seconds in the operation level or adjustment level.
This level is for preventing unwanted or accidental modification of param-
eters. Protected levels will not be displayed, and so the parameters in that
level cannot be modified.
• 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 process
value, set point and manipulated variable can be monitored, and the
alarm value and upper- and lower-limit alarms can be monitored and
modified.
• To move the mode at this level, press the
ond.
• This level is for entering set values and offset values for control. This level
contains parameters for setting the AT (auto-tuning), communications
writing enable/disable, hysteresis, multi-SP, input shift values, heater
burnout alarm (HBA) and PID constants. You can move to the top param-
eter of the initial setting level and operation level from here.
• To move the mode at this level, press the
onds in the operation level or adjustment level. The PV display flashes
after one second. This level is for specifying the input type, selecting the
control method, control period, setting direct/reverse action and alarm
type. You can move to the advanced function setting level or communica-
tions setting level from this level. To return to the operation level, press the
key for at least one second. To move to the communications setup
level, press the key for less than one second.
• To select this level, you must enter the password ("-169") in the initial set-
ting level.
• You can move to the calibration level only from this level.
• This level is for setting the automatic return of display mode, MV limitter,
event input assignment, standby sequence, alarm hysteresis, ST (self-
tuning) and for moving to the user calibration level.
• To move the mode at this level, press the
ond in the initial setting level. When the communications function is used,
set the communications conditions in this level. Communicating with a
personal computer (host computer) allows set points to be read and writ-
ten, and manipulated variables to be monitored.
Note This level is available if communications card (E53-CNH03) is fitted
to the unit.
• To move the mode at this level, you must enter the password "1201" in the
advanced function setting level. This level is for offsetting deviation in the
input circuit.
• You cannot move to other levels by operating the keys on the front panel
from the calibration level. To cancel this level, turn the power OFF then
back ON again.
