normal, verify whether the value of the alarm set point is adequate. This parameter
was probably set to a value that is too low.
3.
If the gas level value is abnormally too high and the alarm set point is set to an
adequate value, verify the reading accuracy of the Hydran 201
i
System. Perform a
dissolved gas analysis (DGA; see Section 13.2 on page 13-3).
4.
If the gas level measured by the DGA corresponds to the H201T
i
’s reading, verify the
equipment monitored by the H201T
i
; follow the company regulations.
5.
If the gas level readings are different (taking into account the accuracy of the
apparatus and the method), execute the
ForceSensor Test
command in the
Service
submenu to test the operation of the Hydran 201 sensor. A problem may have
occurred since the last automatic sensor test (which is performed the first and
fifteenth days of each month at midnight).
