2. HART COMMUNICATOR OPERATION
(2) Checking with Integral Indicator
If an error is detected in the self-diagnostic, an error
number is displayed on the integral indicator. If there is
more than one error, the error number changes at two-
second intervals.
See Table 2.4.1 regarding the error numbers.

*1 : This error code appears at capsule problem or when an illiegal overpressure is applied to the
pressure sensor.
*2 : If the normal pressure is regained, the Er.01 will disappear according to the setting of the parameter
of Auto recover. When the Auto recover is set to ON(default setting), the Er.01 will disappear auto-
matically. When the Auto recover is set to OFF, restart the transmitter to cancel Er.01. If no error
code appears then, perform necessary adjustments such as zero-adjustment to continue the
operation. If the error code still appears. replace the capsule assembly.
