Troubleshooting
Abbreviation Definition
LBI
Logical Binary Inputs (card in GenConfig which is used to assign source signal to con-
troller Logical Binary Input functions, e.g. Sys Start/Stop)
LS
Load Sharing - analog load sharing line to interconnect gen-sets on site (for island par-
allel or mains parallel operation of multiple gen-sets); IG/IS/IM-NT controllers use digi-
tal Load Sharing via the CAN2 bus
LSM Load Sharing Module
LT Option for Low Temperature modification (display equipped with heating foil)
MCB Main Circuit Breaker
MGCB
Master Generator Circuit Breaker (sometimes used with multiple gen-sets in island
parallel or mains parallel operation)
MINT
Multiple application with INTernal control loops - for multiple gen-sets in island parallel
or mains parallel operation; Load Sharing and VAr Sharing controlled internally; PMS
available
MP Mains Protection
MultlslOp Multiple Island Operation (MCB is opened, GCB’s are closed)
MultParOp Multiple Parallel Operation (MCB is closed, GCB’s are closed)
NPU Mains protection relay (voltage, frequency, vector shift protections)
OC
Occurrence Count (number of fault occurrences transmitted in diagnostic frame from
ECU)
OfL Off load - protection type (see application manual for details)
PF Power Factor
PGN Parameter Group Number (refer to SAE J1939-71)
PMS
Power Management System - ensures optimization of running gen-sets on sites with
multiple gen-sets; based on kW/kVA spinning reserve or on relative (%) load; no-mas-
ter system ensures high reliability
Reverse synchronisation Synchronisation of loaded generator to mains (MCB closing process)
RTC Real Time Clock
SG Speed Governor
SHAIN SHared (virtual) Analog INput module
SHAOUT SHared (virtual) Analog OUTput module
SHBIN SHared (virtual) Binary INput module
SHBOUT SHared (virtual) Binary OUTput module
Soft load Generator soft loading according to Load ramp loop setting
Soft unload Generator soft unloading according to Load ramp loop setting
SPI
Single Parallel Island application - for single gen-sets in parallel with mains or in island
operation; suitable for CHP applications; no MCB control
SPM Single Prime Mover application - for single gen-sets without mains
SPN Suspect Parameter Number (refer to SAE J1939-71)
SPtM
Single Parallel to Mains application - for single gen-sets in parallel with mains or in
island operation, with AMF support; both MCB and GCB controlled
SSB
Single Stand-By application - for single gen-sets with mains and break transfer to
mains
VPIO
Virtual periphery I/O module – internal “SW wires” linking binary outputs to inputs con-
trollers via inter-controller CAN2
VS
VAr Sharing - ensures VAr sharing between gen-sets on site via the CAN2 bus (for
island parallel or mains parallel operation of multiple gen-sets)
VT Voltage Transformer
#
Setting of setpoints (with this character in front of them) is shared between controllers
controllers via inter-controller CAN2
