Temperature Input Unit
(GRT1-TS2
@ ), contin-
ued
The scaling value overflows or
underflows. (Temperature
data at time of overflow: 7FFE
hex, Temperature data at time
of underflow: 8000 hex) Offset set value is too large,
so the scaled value has
exceeded the display range. Decrease the offset setting so
that the scaled value does not
exceed the scaling value display
range.
Monitoring set value turns ON
immediately. Monitoring set value is not
set appropriately. Check the monitoring set value.
Temperature values are not
being counted even though
they meet the count condi-
tions of the zone counter. Comparator function is not
enabled. • Enable the comparator. (After
enabling, it is necessary to reset
the Configurator or turn the
power supply OFF and ON.)
Unit does not operate as
expected even after the com-
parator function and hystere-
sis have been set. • The temperature display
unit setting is not correct
(
°
C or
°
F).
• The decimal point position
was read incorrectly.
Check the decimal point position
and
°
C/
°
F display for the input
type and display mode. If these
settings have been changed dur-
ing operation, check the compar-
ator and hysteresis settings and
correct if necessary.
The temperature difference
detected by the data compari-
son between channels func-
tion is not operating properly. • Data other than the temper-
ature value is allocated as
the I/O data. (The 1/100
Display Mode must be used
for the data comparison
between channels func-
tion.)
• Assign the temperature value to
the I/O data.
The I/O comment or Unit com-
ment cannot be set. A comment longer than 32
characters is being set. Set a comment of 32 characters
maximum.
The Unit Maintenance Status
Flag will not go ON. The maintenance status
function is set to OFF if the
monitoring set value is set to
0. Set the monitoring set value to a
non-zero value.
