WARRANTY
All products manufactured or marketed by Fagor Automation has a warranty
period of 12 months from the day they are shipped out of our warehouses.
The mentioned warranty covers repair material and labor costs, at FAGOR
facilities, incurred in the repair of the products.
Within the warranty period, Fagor will repair or replace the products verified
as being defective.
FAGOR is committed to repairing or replacing its products from the time
when the first such product was launched up to 8 years after such product

It is entirely up to FAGOR to determine whether a repair is to be considered
under warranty.
EXCLUDING CLAUSES
The repair will take place at our facilities. Therefore, all shipping expenses as
well as travelling expenses incurred by technical personnel are NOT under
warranty even when the unit is under warranty.
This warranty will be applied so long as the equipment has been installed
according to the instructions, it has not been mistreated or damaged by acci-
dent or negligence and has been manipulated by personnel authorized by
FAGOR.

hidraulic valves for the 4 EXECUTION modes.
The rapid approach feed is not managed.
Especially indicated for conventional down-stroke machines.
B. Same as model "A" with a linear encoder or potentiometric scale for decoding
theintermediateramorbedpositionsaffectingthebendingapproachspeedand
depth:
With outputs to relays or to a PLC:
STOP - Top dead point overrun
S9 Fast ram approach.
S29 Slow speed controlled by the footswitches.
S28 Ram retraction.
With internal processing: (without external output).
·Going through "Y=sheet thickness" position to withdraw the X axis.
·Bend position reached to start bending timing on upstroke models that do
not have a presostat.
C- Control of the actual ram/bed position.
With internal processing of all the intermediate positions.
The footswitches control directly the position of the bending tool, Y axis.
