3-2 Limit Control
Formula: PV = IN.LO + ( IN.HI IN.LO ) S-SL
SH-SL
Example: a 4-20 mA current loop pressure transducer with range
0 - 15 kg/cm , is connected to input, then perform the
following setup:
2
INPT = 4-20 mA
UNIT = PU
RESO = 1-DP
IN.LO = 0.0
IN.HI = 15.0
Of course, you may select other value for RESO to alter
the resolution.
OUT1: Selects the output 1 function. The available output 1 functions
are: High Limit Control, Low Limit Control and High/Low Limit
Control. Refer to
for the limit control operation.
Section 1-6
O1.HY: Output 1 hysteresis value. The hysteresis value is adjusted to
a proper value to eliminate the relay jitter in a noisy
environment.
3-3 Set Point Range
HSP.L : Lower limit of HSP1
Hidden if LO is selected for OUT1
HSP.H : Upper limit of HSP1
Hidden if LO is selected for OUT1
LSP.L : Lower limit of LSP1
Hidden if HI is selected for OUT1
LSP.H : Upper limit of LSP1
Hidden if HI is selected for OUT1
HSP.L and HSP.H in setup menu are used to confine the adjustment
range of HSP1. LSP.L and LSP.H are used to confine the adjustment
range of LSP1.
