Thank you for buying a GESAN generator set.
This manual has been written to assist you in maintaining and operating your generator set
correctly. Please read it carefully before putting the machine into operation so as to become
familiar with the precautions to be taken during use and be able to perform maintenance in ideal
conditions.
Please keep this manual at hand for consultation at all times and ensure it is included with the
machine should it be re-sold.
GRUPOS ELECTROGENOS GESAN, S.A. is constantly striving to improve its products, and
regularly introduces changes to the equipment it supplies. For this reason the characteristics
and information contained in this manual may be modified without prior notice and without
incurring any obligation.
If any problems or queries arise, please contact your distributor.

SAFETY INSTRUCTIONS
Please read carefully the following warnings for your own safety and the safety of others :
1. Make sure that the control panel is well lit if you run your generator set in poor lighting
conditions.
2. Make sure that you know how to stop the generator set in case of emergency and
familiarize yourself with its controls and power outlets.
Do not permit operation by someone unfamiliar with the generator set.
Do not let children operate the generator set without the help of an adult.
Children and pets must be kept at a safe distance from the engine, in order to avoid burns or
injury.
3. Carry out all necessary checks before starting the generator set in order to avoid accidents
or damage to the equipment.
4. Earth the generator set as well as the load properly.
5. Do not operate the generator set when it is raining or where there is snow. YOU MAY BE
ELECTROCUTED.
Do not get the generator set wet, or operate it with wet hands.
6. Do not connect the generator set to the mains. Connection should be carried out by a
qualified electrician in accordance with applicable standards and regulations.
A poorly made connection may cause current returns which could lead to the electrocution of
anybody working on the mains.
7.- The engine exhaust emits sufficient heat to set some substances on fire:
Ensure that the generator set operates at a safe distance from buildings and other equipment
(at least one metre).
Keep all inflammable substances away from the generator set.
Do not touch the engine or the exhaust pipe while the generator set is running. They can
cause serious burns.
Wait until the engine has cooled down before carrying out maintenance or storing it.
8. The fuel used is highly inflammable and volatile :
Ensure that the engine is not running when filling the fuel tank and that the premises are
sufficiently ventilated.
Do not get near flames or sparks while filling the fuel tank.
DO NOT SMOKE near the generator set.
Keep the generator set on a firm, level surface, otherwise fuel may spill and catch light.
Do not over-fill the fuel tank. After filling, ensure the fuel cap is properly closed.
Do not spill fuel when filling the tank. Fuel vapour or spilled fuel may catch light. If fuel is
spilled, ensure the area is dry before starting the engine.

9. Exhaust fumes from the engine are poisonous:
Do not operate the generator set in a closed environment.
If operating the set in an enclosed space, provide adequate ventilation and direct the exhaust
fumes out of the area.
10. If the generator set operates in a place where damp and dust are unavoidable, it must be
dried and cleaned regularly.
11. At the slightest abnormality, stop and disconnect the set. Locate and correct the fault
before starting up again.
12. Regularly inspect all electrical cables. If damaged cables or hazardous connections are
found, stop the unit immediately and replace or correct the faulty cables before starting up
again.
13. Handle batteries with care. Batteries give off explosive gases; keep sparks, flames and
cigarettes well away. Provide adequate ventilation when charging or using batteries in enclosed
space.
Batteries contain sulphuric acid (electrolyte). Contact with the skin or eyes can cause severe
burning. Wear protective clothing and a protective mask.
- If electrolyte comes into contact with skin, wash with water.
- If electrolyte comes into contact with eyes, wash eyes with water for at least 15
minutes and seek medical assistance immediately.
Electrolyte is poisonous. If you swallow it, drink large amounts of water or milk, and follow with
milk of magnesia or vegetable oil and seek medical assistance.
Use only distilled water in batteries. Tap water will shorten battery life. If the battery is filled
above the maximum level the electrolyte will overflow causing corrosion of the engine or
adjacent parts. Clean away electrolyte which has been spilled.
14. Used oil can cause skin cancer in cases of prolonged and frequent contact. Although this
is unlikely, washing your hands after contact with used motor oil is recommended.
KEEP OUT OF THE REACH OF CHIDREN.
Please refer also to the engine and alternator user’s manual.

CONTROL CARD GECO
GECO is an AUTOMATIC CONTROLLER designed to start, control and monitor generator sets
in mains failure situations, and can be used with both 12 and 24 VDC batteries.
OPERATION
GECO can be switched to any one of six different operational modes:
AUTOMATIC
If mains is O.K. the mains light will be illuminated and the mains contactor will be
connected.
The mains contactor and load supplied lights will also be on.
If the mains fails and generator parameters are O.K., the generator lights
will come on.
Three seconds later the mains contactor will open and the generator contactor will close.
The lights will illuminate.
Up to three 20 second starting attempts are possible, with a 10 second pause between each
attempt. If after three attempts the generator has not started, the “Fail to Start” light
will illuminate and the hooter will sound (2 min.).
The start-up signal will cut out when the controller recieves the engine running signal, either by
detecting generator frequency >20Hz or by receiving positive battery current through terminal 4.
When mains returns, after a 60 second delay, the load will be transferred back to mains and the
generator will idle for 2 minutes then shut down.

OVERRIDE MAINS (AUTOMATIC MODE): Light off. Current is supplied by
generator.
OVERRIDE GENERATOR (AUTOMATIC MODE): Light on. Generator will not
start on mains failure.
TEST
Works as TEST WITH LOAD, but the load is not transferred to the generator. If the mains
should fail while in this mode, the load will automatically be transferred to the generator. The
test finishes when the controller is switched to any other mode.
TEST WITH LOAD
Works as AUTOMATIC by simulating a mains failure and transferring the load to the generator.
When the controller is switched to any other position, and if mains is O.K., the load will be
returned to mains.
MANUAL
OFF/RESET
Shuts down the generator and cancels all alarm signals (mains contactor closed). The
lamp lights up.
SERV 1 / START
The load is supplied by the mains (mains contactor closed) and the lamp lights up.
The generator starts and runs manually. Alarm signals work automatically.
SERV 2/ START
Generator starts and runs manually (generator contactor closed). The lamp lights
up.
Alarm signals work automatically.
STOP
Emergency stop. If not switched to OFF the mains contactor closes and the lamp
lights up.
The hooter sounds and the lamp lights up.
ALARM SIGNALS:
FAIL TO START/EMERGENCY STOP/GENERATOR FAIL failure/running
The lamp lights up, the hooter sounds and GECO shuts down the system. Turn the switch to
the OFF position.
