This instruction manual provides all specific information necessary for familiarising
yourself with and correctly using your MARPOSS equipment.
The descriptions in this manual are intended for the following type of personnel:
- MARPOSS or Customer Personnel who are responsible for installation of the
equipment.
- Customer technical personnel who must operate directly with MARPOSS equipment.
- Customer technical personnel responsible for maintenance of the production line in
which the MARPOSS equipment is installed.
All rights reserved. This manual is only for in-house use by the Customer.
Any other use is prohibited
1.2 Testing and Warranty
Material defects are covered by the warranty with the following limitations:
•Warranty period:
the warranty covers the product and all repairs carried out within the terms

rroneously indicates the
probe home position condition. Do not rely exclusively on the probe
signals to stop machine movement.

8 Touch and Probing
1.4 Operating Principle
The G25 + P32 application is a surface touch and scanning system based on
transducer technology.
It can be used in two ways:
•As a touch probe (Figure 1) for part checking and positioning.
•As a rapid surface scanning probe (Figure 2)

2.2 P32 Interface Technical Specifications
The equipment allows TOUCH probes equipped with a transducer to be interfaced
with the machine logic and also supplies an analogue output whose voltage is
proportional to the movement of the contact which touches the surface scanned.
On the front of the equipment are the terminal boards for the I/O (D), analogue
output (F), probe input (G), sensitivity adjustment (E) connections and three
LEDs for the following indications:
Green LED (A): when lit indicates that the equipment power is ON.
Yellow LED (B): lit when the head is deflected or in an error condition (linked to
lighting up of the red LED C.).
Red LED (C): lit when there is a probe or connection fault condition, or a probe
output overload (see following pages).
Figure 4: P32 interface
Caution:
Inside the equipment the “0 V” power supply input and the frame earth
are connected. The frame earth must in turn
be connected to the
machine frame.
Therefore, absolutely avoid any machine power
source which is not compatible with this feature.
