3.6.3 Logging Functions
The YTA series have the capability to store the data
useful for diagnosis of the problems.
(1) Error log
Up to four error histories are stored in the transmit-
ter memory, and can be seen using the following
procedures.
1. Call up the “ Error log” display. [1.Device setup
→
2.Diag/Service
→
4.Error log]
2. Select “1. Error log view” to show logged errors.
3. To clear the logged errors, return to the “Error log”
display and select “2. Error log Clear”
(2) Max/Min log
Minimum value and Maximum value of the Process
variables during the operation from the last Power-
up are stored in the transmitter memory and can be
checked. The logged data for Process Variables
except for terminal temperature shall be reset at
every Power-off.
1. Call up the “ Max/Min log” display. [1.Device
setup
→
1.Process variables
→
3.Max/Min log]
2. Enter the log display for each process variable.
3. To clear the logged data for Process variables,
return the “Max/Min log” display and select “Max/
Min log Clear”. Select “Execute” and press
ENTER[F4] . Even after this operation, the logged
data for terminal temperature shall remain.
(3) Power Check
This parameter is always reset at power-off.
Therefore, by setting this parameter to “start” after
power-on, the transmitter can be checked if a
temporary loss of power has occured.
Call up the “Power Check” display. [1.Device setup
→
2.Diag/Service
→
5.Power monitoring
→
1.Power Check]. Select “Start” and press
ENTER[F4] . If the parameters is changed to
“STOP” during the normal operation, the transmit-
ter may have experienced a loss of power.
(4) Operate Time
Transmitter’s operation time from the last power-on
is counted. This parameter is reset at every power
off. Call up the “Operate Time” display to check
the time. [1.Device setup
