temperatures alarms will also be suppressed while the generator is not running and will further be
delayed for a couple of seconds after start. This is to allow coolant to circulate and stabilize
temperatures.
All of these informative / warning / alarm messages is made available to the user in the control panel.
Table 5: Informative messages
Coding Meaning
Remark
MS0
VCS is in re-start delay
MS01
USB port on VCS board is connected to host PC
Will precede CAN communication
MS02
VCS is powered up via CAN bus (panel)
MS03
Battle short is active (input from panel, static)
Military applications only
MS04
Cumulative data in VCS memory not synced
VCS board will retrieve data from panels
MS05
Actuator current has reached peak level
VCS will retract actuator
MS06
Not used on this control system
MS07
Coolant temperature above max. level
User needs to check coolant system
Table 6: Warning messages
Coding Meaning
Remark
MW00
Battery voltage is low
MW01
Frequency is out of range
MW02
VCS temperature is high
MW03
CT board temperature is high
MW04
Tank level is low
MW05
HW problem with CAN bus in VCS
MW06
Oil pressure above plausible value
Differs from checking supply voltage for sensor
MW07
Engine is running but AC voltage does not build up
Reading AC frequency but not voltage
MW08
CT data invalid; Running on VCS
MW09
Fuel pump current is low
MW10
Fuel pump current is high
MW11
Missing coil temperature sensor
MW12
Actuator is misaligned or not calibrated
MW13
Current GND breaker too high, output is off
Will reset if below warning level, will latch if above
shutdown. Will unlatch with POR only
MW14
Missing temperature sensor for coolant in
MW15
Missing CT board. Using VCS readings for control.
MW16
Panel is not programmed
MW17
Missing alternator bearing temp. sensor
MW18
Tank sensor is enabled but it is not working
MW19
AC voltage is not balanced
MW20
Missing temp. sensor for cylinder head
MW21
No panel connected to the VCS
MW22
CT board is not programmed / not calibrated
MW23
CT board sensing AC current but no pulses
MW24
AC inputs on CT board read DC
MW25
None of the CT terminal temp. sensors reading OK
MW26
VCS not reporting AC readings
Using CT board instead
MW27
VCS is not reading AC voltage or AC frequency

Bit
Meaning
Remark
ST00
Internal VCS hardware problem, generator will not start
Problem while accessing SPI bus or reverse polarity
protection MOSFET not engaging
ST01
Fuel pump output is in short-circuit
Will not reset other than through power cycle
