Setting Level Configuration and Key Operations Section 1-3
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.
(4) When the PF Setting is set to A-M in models with a PF Key (E5AN/EN)
(5) When the PF Setting is set to PFDP in models with a PF Key (E5AN/EN)
Protect Level • To switch to the protect level from the operation level, the adjustment
level, or the monitor/setting item level, simultaneously hold down the O
and M Keys for at least 3 seconds. (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).
Operation Level • The operation level is displayed when the power is turned ON. You can
move to the protect level, initial setting level, or adjustment level from this
level.
• Normally, select this level during operation. While operation is in progress,
items such as the PV and manipulated variable (MV) can be monitored,
and the set points, alarm values, and alarm upper and lower limits can be
monitored and changed.
Adjustment Level • To move to the adjustment level, press the O Key once (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, multi-SP settings, and input offset parameters, it
includes HB alarm, HS alarm, OC alarm, and PID constants. From the
adjustment level, it is possible to move to the top parameter of the initial
setting level, protect level, or operation level.
Monitor/Setting Item Level • To switch to the monitor/setting item level, press the PF Key from the
operation level or adjustment level. The contents set for monitor/setting
items 1 to 5 can be displayed. You can move from the monitor/setting item
level to the operation level or initial setting level. (This level is supported
by the E5AN and E5EN only.)
Manual Control Level • When the O Key is pressed for at least 3 seconds from the operation
level's auto/manual switching display, the manual control level will be dis-
played. (The MANU indicator will light.)
• When the PF Setting is set to A-M (auto/manual) and the PF Key is
pressed for more than one second from the operation level or adjustment
level, the manual control level will be displayed (E5AN and E5EN only.)
• This is the level for changing the MV in manual mode.
• To return to the operation level, press the O Key for at least one second.
It is also possible to return to the operation level by pressing the PF Key
for more than one second when the PF Setting is set to A-M.
Advanced function setting level --- Can be set.
