Setup Level Configuration and Front Panel Keys Section 6-3
Protect Level To move the mode to this level, simultaneously press the Level and Mode
Keys for at least three seconds in the operation level or adjustment level. This
level is for preventing unwanted or accidental modification of parameters. Pro-
tected levels will not be displayed, and so the parameters in that level cannot
be modified.
Operation Level • This level is initially displayed when you turn ON the power to the E5ZN.
You can move to the protect level, initial setting level, and adjustment
level from this level.
• During operation, the PV, SP, and manipulated variable can be monitored,
and the SP, alarm value and upper and lower limit alarms can be moni-
tored and modified.
Adjustment Level • To move the mode to this level, press the Level Key for less than one sec-
ond.
• This level is for entering set values and offset values for control. This level
contains parameters for setting the autotuning, communications writing
enable/disable, hysteresis, multi-SP, input shift values, heater burnout
alarm (HBA) settings, PID constants, etc. You can move to the top param-
eter of the initial setting level and operation level from here.
Initial Setting Level To move the mode to this level, press the Level Key for at least three seconds
in the operation level or adjustment level. The first 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 communications setting level
from this level. To return to the operation level, press the Level Key for at least
one second. To move to the communications setup level, press the Level Key
for less than one second.
The display will be blank “----” when you move from the initial setting level to
the operation level.
Advanced Function
Setting Level
• To enter this level, you must enter the password “-169” in the initial setting
level.
• You can move to the initial setting level only from this level.
• This level is for setting the MV limits, event input assignment, standby
sequence, alarm hysteresis, and other parameters.
Communications
Setting Level
To move to this level, press the Level Key for less than one second in the initial
setting level. When the communications settings are to used, set the commu-
nications conditions in this level. Communicating with a personal computer
(host computer) allows SPs to be read and written, and manipulated variables
to be monitored.
