Abbreviation
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 gensets in parallel with mains or in
island operation; suitable for CHP applications; no MCB control
SPM Single Prime Mover application - for single gensets without mains
SPN Suspect Parameter Number (see SAE J1939-71)
SPtM Single Parallel to Mains application - for single gensets in parallel with mains or in island operation,
with AMF support; both MCB and GCB controlled
SSB Single Stand-By application - for single gensets with mains and break transfer to
mains
VPIO Virtual periphery I/O module – internal "SW wires" linking binary outputs to inputs
controllers via inter-controller CAN2
VS VAr Sharing - ensures VAr sharing between gensets 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

Table 8 - Digital Controller List of Alarms
Indication of error in communication with ECU.
Check if the ECU is:
- correctly connected to the CAN1 port of the controller (see ComAp Electronic Engines
Support manual for information about ECU connection)
- powered up
- terminating resistors are properly connected
- the CAN bus Low and High wires are not swapped
Shared Analog module configuration error – i.e. more than one source module
(SHAOUT) were configured (on the CAN2 bus). Make sure that only one SHAOUT x
module is configured in controllers.
Alarm is active when Comms settings: ECU diag = DISABLED. This setting means that
ECU alarms are not displayed and considered by controller and this alarm is the setting
notification.
Wrong controller configuration indication.
Indicates that controller hardware doesn't support PLC used in configuration. To check it
send the IDch and Dngl strings3 from controller Info screen 2 and archive to your techni-
cal support.
