Level 0
In this level, parameters such as the alarm setting, input shift values
can be set or changed. When these parameters are being set or
changed, the new values are displayed on the SV display. The pa-
rameter to be set or changed is selected by pressing the Display
Key the required number of times.

Process Value
While the process temperature is displayed, the desired tempera-
ture can be set with Up and Down Keys. The value is factory-set to
0
°

F.
Bank No.:
bk
When “
bk
” is displayed on the PV display, the memory bank num-
ber can be set with Up and Down Keys. The memory bank number is
factory-set to 0. This means the E5AX-BA/E5EX-BA operates with
the values set in memory bank 0 if the memory bank number is not
reset before use.

Alarm:
al
When “
al
” is displayed on the PV display, the alarm value for alarm
output can be set on the SV display with Up and Down Keys. Usual-
ly, the alarm value is set as a deviation from the main setting, but it
can also be set as an absolute value when the absolute value alarm
mode is selected. The message is not displayed if the alarm mode
selector is set to position 0. The value is factory-set to 0

” is displayed on the PV display, the input shift value
can be set on the SV display with Up and Down Keys. When a plati-
num resistance thermometer is used, the range is from –99.9

” is displayed on the PV display, the propor-
tional band (P constant) can be changed using the Up and Down
Keys. The new value will be displayed on the SV display. It can be
set in a range from 0.1

Integral Time :
i
When the character “
i
” is displayed on the PV display, the integral
time (I constant) can be changed using the Up and Down Keys. It
can be set in a range from 0 to 3,999 seconds in units of 1 second.
The value is factory-set to 240 seconds.
Derivative Time :
d
When the character “
d
” is displayed on the PV display, the deriva-
tive time (D constant) can be changed using the Up and Down Keys.
It can be set in a range from 0 to 3,999 seconds in units of 1 second.
The value is factory-set to 60 seconds.
Memory Bank Function
The E5AX-BA/E5EX-BA has 8 memory banks (memory bank 0
through 7) where parameters such as main setting, alarm values,
PID constants, and input shift values can be preset. By switching
from a memory bank to another, different parameters can be se-
lected at a time with ease.
Memory Configuration of the E5AX-BA/E5EX-BA
Memory Bank 0 to 7
The following parameters are set separately for each bank.
Main setting, alarms 1 and 2, input shift, proportional band, integral
time, derivative time, and hysteresis.
Common Data
The same values are used for the following parameters, regardless
of the bank setting. Upper-/lower-limit values of the setting range,
and control period.
Bank Number Display
The selected memory bank number is displayed on the bank num-
ber display and the control operation is effected according to the pa-
rameters preset in the selected memory bank.
