PRECAUTIONS AGAINST PRODUCT DAMAGE

•Working environment.

This unit is ready to be used in industrial environments complying with the directives and regulations effective in the European Community.

Fagor Automation shall not be held responsible for any damage suffered or caused when installed in other environments (residential or homes).

•Install this unit in the proper place.

It is recommended, whenever possible, to install the CNC away from coolants, chemical product, blows, etc. that could damage it.

This unit complies with the European directives on electromagnetic compatibility. Nevertheless, it is recommended to keep it away from sources of electromagnetic disturbance such as:

Powerful loads connected to the same AC power line as this equipment.

Nearby portable transmitters (Radio-telephones, Ham radio transmitters).

Nearby radio/TV transmitters.

Nearby arc welding machines.

Nearby High Voltage power lines.

Etc.

•Enclosures.

The manufacturer is responsible of assuring that the enclosure involving the equipment meets all the currently effective directives of the European Community.

•Avoid disturbances coming from the machine tool.

The machine-tool must have all the interference generating elements (relay coils, contactors, motors, etc.) uncoupled.

DC relay coils. Diode type 1N4000.

AC relay coils. RC connected as close to the coils as possible with approximate values of R=2201 W y C=0,2 µF / 600 V.

AC motors. RC connected between phases, with values of R=300 / 6 W y C=0,47 µF / 600 V.

•Use the proper power supply.

Use an external regulated 24 Vdc power supply for the inputs and outputs.

•Grounding of the power supply.

The zero volt point of the external power supply must be connected to the main ground point of the machine.

•Analog inputs and outputs connection.

It is recommended to connect them using shielded cables and connecting their shields (mesh) to the corresponding pin.

•Ambient conditions.

The working temperature must be between +5 ºC and +40 ºC (41ºF and 104º F) The storage temperature must be between -25 ºC and +70 ºC. (-13 ºF and 158 ºF)

•Central unit enclosure (8037 CNC).

Make sure that the needed gap is kept between the central unit and each wall of the enclosure. Use a DC fan to improve enclosure ventilation.

•Power switch.

This power switch must be mounted in such a way that it is easily accessed and at a distance between 0.7 meters (27.5 inches) and 1.7 meters (5.5ft) off the floor.

WARRANTY TERMS

INITIAL WARRANTY

All products manufactured or marketed by FAGOR carry a 12-month warranty for the end user which could be controlled by the our service network by means of the warranty control system established by FAGOR for this purpose.

In order to prevent the possibility of having the time period from the time a product leaves our warehouse until the end user actually receives it run against this 12-month warranty, FAGOR has set up a warranty control system based on having the manufacturer or agent inform FAGOR of the destination, identification and on-machine installation date, by filling out the document accompanying each FAGOR product in the warranty envelope. This system, besides assuring a full year of warranty to the end user, enables our service network to know about FAGOR equipment coming from other countries into their area of responsibility.

The warranty starting date will be the one appearing as the installation date on the above mentioned document. FAGOR offers the manufacturer or agent 12 months to sell and install the product. This means that the warranty starting date may be up to one year after the product has left our warehouse so long as the warranty control sheet has been sent back to us. This translates into the extension of warranty period to two years since the product left our warehouse. If this sheet has not been sent to us, the warranty period ends 15 months from when the product left our warehouse.

This warranty covers all costs of material and labour involved in repairs at FAGOR carried out to correct malfunctions in the equipment. FAGOR undertakes to repair or replace their products within the period from the moment manufacture begins until 8 years after the date on which it disappears from the catalog.

FAGOR has exclusive competence in deciding whether the repair enters within the term defined as the warranty period.

EXCLUDING CLAUSES

Repairs will be carried out on our premises. Therefore, all expenses incurred as a result of trips made by technical personnel to carry out equipment repairs, despite these being within the above-mentioned period of warranty, are not covered by the warranty.

Said warranty will be applied whenever the equipment has been installed in accordance with instructions, has not be mistreated, has not been damaged by accident or by negligence and has not been tampered with by personnel not authorized by FAGOR. If, once servicing or repairs have been made, the cause of the malfunction cannot be attributed to said elements, the customer is obliged to cover the expenses incurred, in accordance with the tariffs in force.

Other warranties, implicit or explicit, are not covered and FAGOR AUTOMATION cannot be held responsible for other damages which may occur.

WARRANTY ON REPAIRS

In a similar way to the initial warranty, FAGOR offers a warranty on standard repairs according to the following conditions:

PERIOD	12 months.
CONCEPT	Covers parts and labor for repairs (or replacements) at the network's own
	facilities.
EXCLUDING CLAUSES	The same as those applied regarding the chapter on initial warranty.
	If the repair is carried out within the warranty period, the warranty extension
	has no effect.

When the customer does not choose the standard repair and just the faulty material has been replaced, the warranty will cover just the replaced parts or components within 12 months.

For sold parts the warranty is 12 moths length.

MAINTENANCE CONTRACTS

The SERVICE CONTRACT is available for the distributor or manufacturer who buys and installs our CNC systems.

·18·

MATERIAL RETURNING TERMS

When sending the central nit or the remote modules, pack them in its original package and packaging material. If the original packaging material is not available, pack it as follows:

1.Get a cardboard box whose three inside dimensions are at least 15 cm (6 inches) larger than those of the unit. The cardboard being used to make the box must have a resistance of 170 kg. (375 pounds).

2.Attach a label indicating the owner of the unit, person to contact, type of unit and serial number.

3.In case of failure, also indicate the symptom and a short description.

4.Wrap the unit in a polyethylene roll or similar material to protect it.

5.When sending the central unit, protect especially the screen.

6.Pad the unit inside the cardboard box with polyurethane foam on all sides.

7.Seal the cardboard box with packing tape or industrial staples.

The minimum distance from each side of the monitor to its enclosure in order to guarantee the required ambient conditions is shown below:

180 [7.087]	50 [1.968]	50 [1.968]

It is up to the installer to make sure that the enclosure has forced ventilation or ventilation grooves in order to prevent the inside temperature to exceed the specified ambient temperature.

Between 5º C and +50º C (41º F and 122º F)

Relative humidity between 5% and 95% non condensing

When using a fan to better ventilate the enclosure, a DC fan must be used since an AC fan may generate electromagnetic interference resulting in distorted images being displayed by the CRT.

Do not get into the inside of the unit. Only authorized personnel from Fagor Automation may do it. Do not handle the connectors with the unit connected to main AC power. Before manipulating these connectors, make sure that the unit is not connected to main AC power.

The machine manufacturer must comply with the EN 60204-1 (IEC-204-1) standard in terms of protection against electrical shock due to faulty I/O contacts with external power supply.

Installation manual

Protection at the connectors

It detects over-currents or short-circuits at the +5 V of the feedback of the handwheels, spindle and probe and it issues the relevant error message.

Besides this, it also detects the 24V of the external supply at the digital outputs.

Hardware protections

The axis board installed in the CNC includes the recognition of the 24V at the inputs and outputs.

Signal adapters

The following signal adapters are available to be used with the feedback inputs.

SA-TTL-TTLD	Adapter for "Non-differential TTL" to "differential TTL" signals
SA-FS-P	Adapter for Fagor sinusoidal signal to Vpp signal.
