Hydraulic Generator Controller – HGC-2

‘Data Logging’ Options :
The HGC-2 controller can log operational data as long
as it is connected to the host PC. The data is directly
saved onto the PC hard drive as a CSV format file, into
a location that can be selected by the user.
Logging is started by the user clicking the ‘Log Data’
button
The controller logs the following data:
1.
Valve coil Current
2. PSU voltage
3. Frequency feedback
Information transfer rate from the controller to the
CSV file is governed by the host PC performance
Fault Screens :
OPEN CIRCUIT FAULT DETECTED:
This fault is displayed when the
controller detects that the proportional
coil being driven by the PWM output
has become dis-connected or has
failed internally to an open-circuit
condition. Other causes of this fault
detection may be broken wires within
the generator set enclosure.
If this fault is triggered, the HGC-2
PWM output will be set to zero output
( i.e. minimum generator speed ) until
the HGC-2 is first disabled and re-
enabled or the supply power to the
unit is cycled and no further open
circuit is detected.
To correct this issue, the operator
should first isolate and fully stop the
generator and check all connections
to and from the HGC-2 controller for correct and firm connection. If the faulty still exists, check the solenoid coil for continuity
and correct Ohmic value ( see manufacturer details ) or change the solenoid coil.
