This function is to indicate the message for error state.
Message Descriptions
HHHH
If input value is higher than the input range, it will flash every 0.5
sec.
→ When input value is within the input range, it will be automatically
cancelled.
In case of analog input: If full scale(F.S) of input range is within
±10%, it will indicate PV
only on LCD display and it will record PV with either HH or LL
simultaneously as the (a) of following figure.
If full scale(F.S) of input range is out of ±10%, it will indicate and
record HHHH, HH or LLLL, LL as the (b) of following figure. But in
case of Hi < Lo setting, it will be indicated oppositely.
Therefore in case of 0 to 20mA input and Hi scale=0, Lo scale=100,
then if input is out of 20mA, it will indicate LLLL, not HHHH. (In case
of 1V analog input, HHHH, LLLL do not operate.)
In case of TC, RTD input: After setting HI,LO Graph value within
sensor temperature range,
if PV is out of HI,LO Graph value, it will indicate PV only on LCD
display and it will record PV with either HH or LL simultaneously as
the (c) of following figure.
After setting HI,LO Graph value same as sensor temperature range,
if PV is out of temperature range, it will indicate and record HHHH
or LLLL as the (d) of following figure.
LLLL
If input value is lower than the input range, it will flash every 0.5 sec.
When input value is within the input range, it will be automatically
cancelled.
In case of analog or TC, RTD input, indicating will be same as
above.
(In case of 1V analog input, HHHH, LLLL do not operate.)
BURN
If input except for 10V input is disconnected, it will flash every 0.5
sec.
→ When input is connected normally, it will be automatically
cancelled.
Time
Set!!
If time setup is fault for re-recording function by record backup or
P.End, it will be indicated. If start time and stop time are same on
reservation record function, it will be indicated. If pressing key,
it will be cancelled and returned to previous setting state.
