5 Setting the load controller
Door X60 is used for IntLC... choice and a temperature modulationg probe is
used.
ATTENTION: in case of FGR, it is not possible to connect a
modulating temperature probe at the X60 door of the
LMX5...
See the proper chapter for configuration.
Door X60 is used for IntLC.... choice and a pressure probe is used.
It can be used also if the temperature probe has an analogue exit or a
converter from Ohm to mA /V is used.
In this case the right input must be set.
ATTENTION: in case of FGR, it is possible to connect a
modulating temperature probe at the X61 door of the
LMX5...
Door X62 is used for ExtLC...
The input signal come from an external load modulator.
Door X62 is also used to switch from one setp oint to onother one when
IntLC... is used, by measn the opening and closing of the contact between
X62.1 and X62.2 terminals
Door X63 is used to remote a load % signal output from the LMV to the client
DCS or PLC
Output Value Selection are: Load / Load 0 / O2 / Pos Air / Pos Fuel / Pos
Aux1 /Pos Aux2 / Pos Aux3 / Speed VSD / Flame / Temp Pt1000 /
TempNi1000 / Temp Pt100 / Temp X61 / Press X61)
IntLC....must be set together with a modulating probe (temperature or pressure). The probe and its signal must be configured. Doors allowed are X60 for
temperature probe and X61 for pressure probes or analogue output probes.
ExtLC... must be set together with an external input signal of modulation (analogue or bus) coming from an external output modulator. The input must be
configured. Doors allowed are X62 for the type of signal choice.
