7.1 Structure of Parameters
·
To calibrate the E5AK controller, select [
] in the menu display to
select the calibration mode. [
] is displayed.
·
However, note that [
] may not be displayed on the menu display
when, for example, the user is calibrating the E5AK controller for the
first time. If this happens, [
] is displayed by changing the “secu-
rity” parameter (protect mode) to “0”.
·
The parameters in the calibration mode are configured as follows.
0 to 10V
0 to 5V 1 to 5V
Thermocouple
Thermocouple 1
Transfer output
Data save
Platinum resistance
thermometer
Voltage input
Current input
Thermocouple 2
Thermocouple 1
: K1/J1/L1/E/N/W/PL
II
Thermocouple 2
: K2/J2/L2/R/S/B/T/U
Platinum resistance
thermometer
: JPt100/Pt100
Only when transfer
output function is
supported
·
To select the desired parameter, press the
key. Parameters are dis-
played in the following order:
Calibration of inputs
®
Calibration of transfer output
®
Saving of calibration data
If the E5AK controller does not support the transfer output function,
calibration of transfer output is automatically deleted from the calibra-
tion procedure as follows:
Calibration of inputs
®
Saving of calibration data
·
Only inputs that have been set in the “input type” parameter (setup
mode) can be calibrated. To temporarily save data for each of the calibra-
tion parameters, press the
key for 1 second.
·
Transfer output can be calibrated only when the communications unit
(E53-AKF) is set in the controller. To adjust data items, press the
or
keys.
·
The data save menu is displayed only when all calibration items have
temporarily been saved.
·
After calibrating input, you must always check indication accuracy. For
details, see page 7-12.
