DIGITAL PID CONTROLLER

4) Retransmission output
④ Notice of LBA
In the retransmission output mode, process value (PV), set value (SV),
output amount (MV), or sensor power supply (SPS) may be chosen,
and the output will be generated in direct current of 4~20mA. (SPS is
DC15V/25mA)
ⅰ. LBA will work when PID calculations is 0% or 100%. Thus the time from
occurring of abnormalities to alarm time will be the time of PID value 0%
or 100% plus.
ⅱ. LBA set-up times LBA will not working during auto tuning.
ⅲ. The LBA function is influenced by disturbances (heat sources, etc) and
as a result may be activated even if there is no trouble in the controlled
system.
ⅳ. When LBA setting time is too short or wrong control target, sometimes
LBA will be on/off abnormally of not turned on. In this case please set
LBA time little longer.
Retransmission type or SPS selection
PV ( Current Progress Value )
SV ( Set Value )
MV ( Manipulated Variable )
SPS ( Power supply for external sensor )
Scale setting can only possible when
retransfer output set-up PV or SV.
③ Cause of activation
LBA will activate below condition.
ⅰ. Abnormalities of the control target :
Heater break, No supply voltage,
`Wrong wiring, etc.
ⅱ. Abnormalities of the sensor : Disconnection / short circuit of sensor
ⅲ. Abnormalities of the handling tools : Splice relay, wrong wiring, etc.
ⅳ. Abnormalities of Output circuit : Spliced relay inside of unit, break
ON/OFF
ⅴ. Abnormalities of input circuit : No calculations change even input is
change.
