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.
CNC 8037
·17·
WARRANTY ON REPAIRS
In a similar way to the initial warranty, FAGOR offers a warranty on standard repairs according to the
following conditions:
PERIOD
CONCEPT
EXCLUDING CLAUSES
When the customer does not choose the standard repair and just the faulty material has been replaced,
Warranty terms
the warranty will cover just the replaced parts or components within 12 months.
For sold parts the warranty is 12 moths length.
The SERVICE CONTRACT is available for the distributor or manufacturer who buys and installs our CNC
systems.
12 months.
Covers parts and labor for repairs (or replacements) at the network's own
facilities.

Enclosure
The minimum distance from each side of the monitor to its enclosure in order to guarantee the
required ambient conditions is shown below:
1.
CNC structure
CNC CONFIGURATION
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.
