Message Description Message Description
HHHH
In•case•Input•Type•is•temperature•sensor(thermocouple,•
RTD),•if•input•value•is•higher•than•upper•limit•range,•
this•error•message•ashes.•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•ashes.•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•ashes.•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•ashes.•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.
Ex)•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.•
Ex)•When•lower•limit•input•range•is•0•and•current•value•
is•-1,•it•displays•as•-1_L.
BURN
If•input•is•break,•this•error•message•ashes.•When•input•
is•connected,•it•is•removed•automatically.
Prints•BH(display•value•by•break•is•High)•or•BL•(display•
