Error message
Description
HHHH
In case Input Type is temperature sensor(thermocouple, RTD), if input value is
higher than upper limit range, this error message flashes. If input value is within
upper limit range, it is removed automatically.
In case Input Type is analog(current, voltage), if input value is higher than over
10% of upper limit input range, this error message flashes. If input value is within
10% of upper limit input range, it is removed automatically.
Prints HH.
LLLL
In case Input Type is temperature sensor(thermocouple, RTD), if input value is
lower than lower limit range, this error message flashes. If input value is within
lower limit range, it is removed automatically.
In case Input Type is analog(current, voltage), if input value is lower than over
10% of lower limit input range, this error message flashes. If input value is within
10% of lower limit input range, it is removed automatically.
Prints LL.
_H
In case Input Type is analog(current, voltage), if input value is higher than below
10% of upper limit input range, “_H” is displayed with current value to notify that
current value is higher than upper limit input range.
E.g.) When upper limit input range is 100 and current value is 102, it displays as
102_H.
_L
In case Input Type is analog(current, voltage), if input value is lower than below
10% of lower limit input range, “_L” is displayed with current value to notify that
current value is lower than lower limit input range.
E.g.) When lower limit input range is 0 and current value is -1, it displays as -
1_L.
