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.

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.

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.

3. USING THE E32A SSR INTERFACE
3.1 Enabling the output: PROBE OUTPUT signal
The output can be enabled using the ENABLE P.O. input signal. This signal enables the user to control the
P.O. output (by selecting the TRUE/FALSE logic level) even when the measurement cycle is not running.
Enable P.O. = TRUE sets the P.O. signal to TRUE when the measurement cycle is not running, otherwise it
will always set it to FALSE. Therefore it is best to use one of the two following configurations:
Enable P.O. = TRUE

P.O. = TRUE even when the measurement cycle is not running.
Enable P.O. = ARO

P.O. = TRUE only when the Touch probe is deflected during the
measurement cycle.
The MIDA SET, Electrical MIDA TOOL EYE, and Manual MIDA TOOL EYE arm operating cycle diagrams,
in the two different configurations, are illustrated below.

4. OTHER FUNCTIONS
4.1 Function Inhibit
The function inhibit allows the user to disable touch signal processing.
In other words, when Inhibit = TRUE, the output (P.O.) is held at the false logic value, even when the Touch
probe is deflected (see case 1-2 in Figure 4-1).

4.2 Delay and skip PROBE OUTPUT (JP5-JP6)
The P.O. (Probe Output) can be set to normal, delay or skip mode using jumpers JP5 and JP6 on circuit
board of Interface (see Figure 4-3).
Remove the four screws and open the case in order to access it and Install Jumpers as shown in the
Figure 4-3.

4.3 Recognising the connected arm
When it is switched on, E32A SSR acquires the status of a series of input signals in order to identify the type
of arm it is connected to, and then configures itself accordingly. The resulting configuration, that is
maintained until the equipment is switched off, is indicated for 2 seconds by the 2 LEDs, that remain at the
beginning switched off for 2 seconds and then flash in synchronous way, as follows:
Arm type YELLOW LED/RED LED
Mida-Set 1 Flashing
Manual Mida Tool Eye 2 Flashings
Electrical Mida Tool Eye 3 Flashings
i
Note
O
perating mode other than that specified for the arm type indicates that the configuration is
incorrect and that an equipment alarm is active.
4.4 Selecting SINK/SOURCE operating mode (JP1)
E32A can be programmed so that the J1 connector outputs and inputs operate in the SINK or SOURCE
mode. To program the operating modes install the jumpers JP1 on the circuit board as indicated in the
Figura 4-4).
