The manual must always be kept in a safe place where it is readily available for quick
reference.
The manual should be read carefully, and every paragraph understood by the
operators and technicians doing routine and periodic maintenance.
If the manual is lost or damaged, ask the installer/manufacturer for a copy, quoting
the model, code, serial number and year of manufacture.
Many accidents are caused by poor knowledge and the non-observance of safety
regulations, which must be observed when operating and/or servicing the machine.
To prevent accidents, before using or servicing the machine you should read, understand
and observe the precautions and warnings in this manual.
The following indications have been used to identify the safety messages in this manual:
WARNING! This indication is used in the safety messages for risks which,
unless avoided, can cause malfunction or damage to property or persons.
INFORMATION! This term implies the message provides information useful
for performing the current operation, or explanations or clarifications for
procedures.
INFORMATION! on the disposal of old electrical and electronic equipment (applicable in
European countries that have adopted separate waste collection systems).
Products bearing the barred wheeled waste container symbol cannot be disposed of with
normal urban waste. Old electrical and electronic equipment should be recycled in a facility
authorized to process these items and dispose of the components. Contact your local authority
for information on where and how to deliver such products to the authorized site nearest you.

and immediate emergency engine shut-down.
POWER-OFF - is used to indicate a fault that prevents the generator from operating and causes the
standard automatic engine shutoff (including a cooling phase).
WARNING - is used to indicate a fault that requires the intervention of the operator without engine
shutoff.
MAINS –Public power supply line.
LOAD/BUS –Electrical power supply line of the loads. It can be connected to more gensets
GENERATOR –Electricity line that is connected to the alternator of the Generator set
LOAD –Electrical power supply line of the loads. This can be connected to the Mains or to the
Generator
MCB - Switch or component to manage the switching between the Mains line and the Load line.
GCB –Switch or component to manage the switching between the Generator line and the Load line.
CANBUS - Interface for the control and diagnostics of engines equipped with SAE J1939 or CanBus

ISLAND - Type of plant where one or more gensets supply the Load without being in parallel with the
Mains.
MPM –Type of plant working in Island mode and gensets working in parallel among them.
SSB + SSTP (Single Stand By + Single Short Time Parallel) - Type of plant where the genset starts and
supplies the Load in case of Mains failure; once back to normal conditions, it carries out a short time
parallel with the Mains, it disconnects from the Mains and from Load and it stops in stand-by. Depending
on the configuration of the plant, it is also possible to synchronize the Genset with the Mains before
disconnecting it in order not to leave the Load without supply.

The page S.12 (GC400x) (DIGITAL INPUTS) (not available on GC315) is displayed only if
DITEL modules have been configures.
The page S.13 (GC315x) (DIGITAL OUTPUTS) shows the status of the controllers digital
outputs.
Pressing the ACK/ENTER , button, scrolls through three different pages (LOGIC
STATE, PHYSICAL STATE, BY FUNCTION), showing the status of the digital inputs:
- LOGIC STATE: The output's logic state (active or inactive) controlled by the Gen-set in
the management of the operating sequence.
- PHYSICAL STATE: Electrical level (active or inactive, or high or low) actually present on
the output; this can be the opposite in comparison to the corresponding logic state.
Displayed in negative.
- BY FUNCTION: Displays the main states of the digital outputs.
