Internal Faults; External Faults; Model Selection - Procom DGC-7RR Operating Instructions Manual

There are two categories of faults

Internal Faults

o

External faults

o
12.1 Internal Faults
Internal faults are the faults, which do not need any external signals and are detected by the system
itself. They are:
Generator Fails to Start.
o
Generator Voltage Unhealthy
o
Generator Frequency Unhealthy.
o
Generator Over Speed.
o
Generator Fails to Stop.
o
Over Current ( In models with built in Current measurements)
o
LLOP
o
HWT
o
Fuel
o
Battery Under or Over voltage (Warning only).
o
12.2 External Faults
Those faults which cannot be sensed by the unit itself (these faults are not reflected by the
generator voltage) and are to be provided externally. They are:
Canopy Temperature
o
Emergency
o
Over Current (External)
o
V-Belt
12.3 Fault Reset
Internal Faults & LLOP fault: All internal faults and LLOP fault can be reset by pressing (R)
o
switch after the generator is stopped.
External Fault except LLOP & V-Belt faults: These faults cannot be reset till the engine is
o
running and/or fault conditions persist. Once the faults are rectified, the fault can be reset by pressing
Reset switch (R). In case the engine fails to stop "STOP KEY" can be pressed for manual attempt to
stop engine
13.0 Communication
Half Duplex, RS485 communication running in slave mode: The communication can be used for the
following:
• Programming the parameters
• Reading instantaneous parameters
• Reading system conditions
• Reading fault status.
• Remote Operation
14.0

Model Selection

The nomenclature for selecting the model is as follows:
DGC-7R
-1P/3P for Single Phase /3 Phase Mains monitoring
-A for Annunciation Contacts are required
-B for BTS Vol
S.No Desired Features

mains
2 Annunciation, BTS Voltage, Room Temp,
Single Phase mains monitoring
Please note:
