GC250 user manual 3

The manual must be kept with care and must always be available for quick reference.

The manual must be carefully read and understood in each of its paragraphs by the

people who must use the controller and who will carry out normal and periodic

maintenance.

If the manual is lost or damaged, request a copy from the installer or the manufacturer,

providing the model, device code, serial number and year of construction.

Many accidents are caused by insufficient knowledge and failure to apply the safety rules

during standard and/or maintenance operations.

To avoid accidents, before performing any operation and/or maintenance, read, understand

and follow the precautions and warnings contained in this manual.

The following indications have been used to identify the safety messages included in this

manual:

WARNING! This indication is used in safety messages for dangers which, if not

avoided, can cause malfunctions or damage to things or people.

for carrying out the operation in progress or for clarifying or specifying procedures.

Maintenance of this device must be carried out by qualified personnel, in compliance with

current regulations, in order to avoid damage to people or things.

The front panel can be cleaned only with a soft cloth, do not use abrasive products, liquid

detergents or solvents.

INFORMATION! Disposal of old electrical and electronic equipment (valid for

European countries that have adopted separate collection systems).

Products bearingthe symbol of a crossed-out wheeled bin cannot be disposed of with normal

household waste. Old electrical and electronic products must be recycled at a special facility

capable of treating these products and disposing of their components. To find out where and

how to deliver these products to the place closest to you, contact the appropriate municipal

office. Proper recycling and disposal helps to preserve nature and prevent harmful effects

on health and the environment.

not stop the engine.

MAINS: public electricity.

GENERATOR: a synchronous generator made up by a combustion engine (diesel, gas…)

and an alternator.

LOADS: utilities.

MCB: circuit breaker that connects the mains to the loads.

GCB: circuit breaker that connects the generator to the loads.

The backlighting lamp is managed by the controller which switches it off if no button is

pressed within a configurable time (P.0492). To turn it back on, just press any button. It is

possible to disable the automatic switch off by setting parameter P.0492 to 0.

During the engine start-up phase, the lamp is automatically turned off to reduce the

consumption of the controller, in order to make the controller more autonomous in case of

critical conditions of the starter battery. By using parameter P.0493, it is possible to force the

lamp always switched on when the engine is running.

For a correct view of the display, depending on the ambient temperature conditions, the

contrast adjustment may be necessary.

Press the AUTO+DOWN buttons in sequence to decrease the contrast (lighten), press the

AUTO+UP buttons to increase it (darken).

The display has different viewing modes consisting of several pages.

desired mode.

The UP and DOWN buttons are also used to scroll the pages within the selected display

mode.

The top status bar contains navigation, time and/or some status information.

The current display mode is indicated by the appropriate field on the top status bar (1a). The

mode identifier (1a), together with the page identifier (1b) allows you to identify and refer

unambiguously to a page.

The title shows the operating mode of the controller (2), which can be OFF, MAN, AUTO,

TEST, and REMOTE START. It is useful for the operator, as it is displayed even if he is

accessing other pages or display modes.
