2. GENERAL DESCRIPTION AND TECHNICAL DATA
The E32A SSR is a manually or electrically operated, specific interface for tool presetting arms on MIDA-
SET (removable) end MIDA TOOL EYE (resident) lathes. It processes the signal generated by the touch
probe so that it can be used by the machine tool, and manages the control signals; it also controls the Mida
Electrical Tool Eye arm driver motor. It is equipped with two physical outputs for the probe signal. The first
is a sink/source type output, while the other is a solid state relay.
The E32A SSR is designed to mounted on a standsard DIN guide inside the electrical cabinet.
The interface is available in two versions:
•Manual (P/N°. 8303322846) for Mida-Set and Mida Manual Tool Eye Manual arms.
•Elettrical (P/N°. 8303322836) for the Mida Electrical Tool Eye.
•Elettrical I/O SINK (P/N°. 8303322837) for the Mida Electrical Tool Eye.
The following elements are present on the front of the Interface:
1. Arm type identification label (Electric or Manual).
2. Connector J1 to connect E32A to the PLC/CNC.
3. Signaling LEDs.
4. Connector J2 to connect E32A to the Mida arm.

A (max)
Motor power supply Vdc = 24 VDC SELV type (19.2 to 30 VDC) (ripple max 5%);
1.85 A (max)
Outputs power supply (if supplied
from separate source)
Maximum current 100 mA for each output
Interface type SINK/SOURCE (programmable)
SSR output characteristics Solid state relay ±50 Vpk, ±40 mApk
Protection level: IP 20 (IEC 60529 standard)
All the outputs are protected against short circuits, overloads and inductive loads. In case of a short circuit
the current is electronically limited: the output is reset automatically as soon as the short circuit is removed.
The power supplies are protected by internal circuits that prevent damage caused by over-currents and
reverse polarity.
2.2 Storage and working Environment
The E32A Interface and the relative electrical components have been designed and built to be installed in a
heavy industrial environment, and to be used only in closed environments where they are protected from the
weather. Do not use the equipment in residential or light industrial environments.
Unless otherwise specified in the contract, the E32A can only operate regularly in the environmental
conditions set out below. Environmental conditions other than those described may damage the machine or
cause it to malfunction, giving rise to potential hazardous situations for the operator and exposed personnel.
Operating temperature: +5 to + 45 °C (41 to 113 °F).
Operating temperature: +5 to + 45 °C (41 to 113 °F).
Relative humidity The mechanical and electrical components are designed to operate
correctly at a maximum relative humidity level of 90% and temperatures
of up to 31°C (87.8°F), decreasing linearly to a relative humidity level of
50% at a temperature of 40°C (104°F).
Altitude The electrical components are designed to operate correctly up to 2000
m above sea level.
Environmental pollution grade Grade 2 (EN 61010-1 standard)
Position Dry (EN 61010-1 standad)

2.3 Operating characteristics
In addition to the code (shown in the side label), it is possible to tell whether the E32A SSR is the Manual or
Electrical version by the label on the front. In addition to the identification labels and the J1 and J2
connection connectors, there are two signaling LEDs:
Yellow (L1): the touch probe status:
- on The probe finger is deflected
- off The probe finger is at rest
Red (L1):
On when an alarm state is active.
For the first five seconds after it is switched on the E32A SSR LEDs display the specific application
configuration (see paragraph 4.3 “Riconoscimento del braccio collegato” on page 19)".
E32A SSR can be programmed using internal jumpers so that the inputs and outputs to and from the PLC
operate in SINK or SOURCE (see paragraph 4.4 ”Selecting SINK/SOURCE operating mode” on page 19).
The CNC sends special signals that are used to detect the arm operating condition:
Mida Tool Eye:
arm measuring or at rest signals.
Mida-Set: arm or cover inserted on fixed base signals.
The following chapter, which describes how to install the E32A in the machine, includes the wiring diagrams
for the various arms.
