7.3 Error (abnormality) display
Content of error is displayed when an abnormality is generated on this product.
7.3.1 Display on measurement value (PV) side
Display Content Handling Operation at error
Over display
* When input exceeds the
display range upper limit
* When thermocouple is
disconnected
* When input of 0 to 10 mV is
disconnected
* When terminal A, B or b is
disconnected for resistance
temperature detector
* Make the input fall within the
display range.
* Correct the disconnection.
* At-abnormality operating
amount FAL 1 or FAL 2 is
output.
Under display
* When input exceeds the
display range lower limit
* When current/voltage input of
other than 0 to 10 mV is
disconnected
* Make the input fall within the
display range.
* Correct the disconnection.
* At-abnormality operating
amount FAL 1 or FAL 2 is
output.
* Input range: Input type measurement range described in the section 6-1, input 1 type setting, on page 6-2.
7.3.2 Display on target value (SV) side
Display Content Handling Operation at error
ERR0
At memory error Request for a repair if
re-power-on does not solve the
error. For output in relay, SSR or open
collector, output OFF is
resulted, and for analog output,
output 0 % is resulted.
ERR1
When an input A/D switchover
error or excessive input is
provided. Remove the excessive input.
Request for a repair if
re-power-on does not solve the
error. At-abnormality operating
amount FAL 1 or FAL 2 is
output.
ERR2
At auto-tuning error Auto-tuning error is displayed
when an input is burned out or
when it takes longer than 3
hours for auto-tuning.
For a subject of control that
cannot be auto-tuned, manually
set the PID value. At-abnormality operating
amount FAL 1 or FAL 2 is
output.
LoC
When a parameter is changed
during key-locking. Release the key-lock. No change of setting value is
allowed, displaying “LoC.”
DI
When target value (setting
value) assigned for DI input is
attempted to change Release the assignment for DI. No change of setting value is
allowed, displaying “DI.”
FUNC
When setting value assigned for
FUNC function is attempted to
change Release the assignment for
FUNC function. No change of setting value is
allowed, displaying
“FUNC.”
REMO
When setting value assigned for
the local/remote function is
attempted to change Release the assignment of the
local/remote function No change of setting value is
allowed, displaying
“REMO.”
ZBNK
When setting value assigned for
the auto bank switching function
is attempted to change Release the assignment of the
auto bank switching function. No change of setting value is
allowed, displaying
“ZBNK.”
