This error can be detected also at start up in
ADAPTIVE mode when the values calculated by
SMART are wrong.
In both cases, the instrument will be forced to work
as a PI controller.

E.140

Error detected when the control action values
calculated by ADAPTIVE algorithm are out of range
by the limits set of the "Hidden group".

NOTE:

NOTE: push any key in order to remove the E.130 and E.140

error indications if the instrument is in local state.
If the instrument is in remote state refer to the Modbus
protocol communication.

The instrument is also capable to detect the following errors:
E.100

Error during data saving in FRAM

E.110

Error in FRAM handling

E.500

Error during auto-zero measurement

E.501

Error during zero integrator measurement
NOTE:

NOTE:

NOTE: when an error E.500 or E.501 is detected, all
input measurement are forced to OVERRANGE
condition.

E.502

Error during reference junction measurement.
NOTES:

NOTES:

NOTES:
1) If this error is detected, the temperature input is

forced to OVERRANGE condition.

2) This error may be generated by an ambient

temperature higher than 70 °C (158 °F) or lower
than -20 °C (-4 °F).

3) When "mV" is the controlled variable this error

is displayed only without affecting the control action.

When one of these errors is detected, contact your supplier.
Two errors, related with the preliminary hardware setting, are
detectable:
2.

change V101 dip switch or end keyboard/serial link
configuration.

wrong position of the V101 dip switch.

When one of these error is detected, the display blanks and the
error code is shown on most significant digit of the upper display.
Correct the V101 setting.
