KWP2000
Key Word Protocol of Scania S6 unit (for engine diagnostics)
LS
Load Sharing - analog load sharing line to interconnect the gen-sets on the site (for isolated
parallel or mains parallel of multiple gen-sets); IG/IS-NT controllers use digital Load Sharing
via CAN2 bus
LSM
Load Sharing Module
LSO
Load Sharing Output
LT
Option for Low Temperature modification (display equipped with heating foil)
MCB
Mains 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
NPU
Mains protection relay (voltage, frequency, vector shift protections)
OC
Occurrence Count (number of fault occurrances transmitted in diagnostic frame from ECU)
OfL
Off load - protection type (see application manual for details)
PGN
Parameter Group Number (refer to SAE J1939-71)
PMS
Power Management System - ensures optimization of running gen-sets on the site with
multiple gen-sets; based on kW/kVA spinning reserve or on relative (%) load; no-master
system ensures high reliability
SHAIN
Shared (virtual) Analog INput module
SHAOUT
Shared (virtual) Analog OUTput module
SHBIN
SHared (virtual) Binary INput module
SHBOUT
SHared (virtual) Binary OUTput module
SPI
Single Parallel Island application - for single gen-sets in parallel with mains or in island
operation; suitable for CHP application; 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 gen-set to
mains
VPIO
Virtual periphery I/O module
– internal “SW wires” linking binary outputs to inputs
VS
VAr Sharing - ensures VAr sharing between the gen-sets on the site via CAN bus (for
isolated parallel or mains parallel of multiple gen-sets)
VSO
Var Sharing Output
