Setting Level Configuration and Key Operations
Note
Protect Level
Operation Level
Program Setting Level
Adjustment Level
PID Setting Level
Level
Calibration level
Communications setting level
Of these levels, the initial setting level, communications setting level,
advanced function setting level, and calibration level can be used only
when control is stopped. Control outputs are stopped when any of
these four levels is selected.
(1) Your can return to the operation level by executing a software reset.
(2) You cannot move to other levels by operating the keys on the front panel
from the calibration level. You must turn OFF the power supply.
(3) From the manual control level, key operations can be used to move to the
operation level only.
(4) When the PF Setting parameter is set to A-M. For the E5CN-HT, press
the M+U Keys at the same time to implement the PF Key.
(5) When the PF Setting parameter is set to PFDP. For the E5CN-HT, press
the M+U Keys at the same time to implement the PF Key.
• To switch to the protect level, simultaneously hold down the O and M
Keys for at least 3 seconds from the operation level, the program setting
level, adjustment level, or PID setting level. (See note.) This level is for
preventing unwanted or accidental modification of parameters. Protected
levels will not be displayed, and so the parameters in that level cannot be
modified.
Note The key pressing time can be changed in Move to Protect Level pa-
rameter (advanced function setting level).
• The operation level is displayed when the power is turned ON. You can
move to the protect level, initial setting level, or program setting level from
this level.
• Operation level should be used during normal operation. The PV, MV, or
other values can be monitored during operation. Hold and advance com-
mands can also be used.
• To move to the program setting level, press the O Key once from the
operation level for less than 1 s.
• In this level, the SPs, times, rates of rise, and other parameters are input
for the programs. From the program setting level, you can move to the
adjustment level, initial setting level, or protect level.
• To move to the adjustment level, press the O Key once from the program
setting level for less than 1 s.
• This level is for entering set values and offset values for control. In addi-
tion to AT (auto-tuning), communications write enable/disable switching,
hysteresis settings, SP settings, and input offset parameters, it includes
HB alarm, HS alarm, OC alarm, and PID constants. From the adjustment
level, you can move to the PID setting level, initial setting level, or protect
level.
• To move to the PID setting level, press the O Key once from the adjust-
ment level for less than 1 s.
• This level is used to input parameters such as the PID values for each PID
set, MV upper and lower limits, and automatic selection range upper and
lower limits. From the PID setting level, it is possible to move to the opera-
tion level, the initial setting level, or the protect level.
