cylinder safety chain. In short, if the instrument activates the outputs, the cylinder must not
move if the machine is not in safety.
Operation occurs as follows: when the START input of the instrument is activated by an external
command, the Press-Right, if ready and with all ENABLE inputs active, activates the downward
output of cylinder GO. With the presence of the GO signal, the cylinder must advance until the
instrument removes the same signal.
With GO output active, the instrument activates the BOOSTER output when it reaches contact on
the piece.
According to the stop parameters reached (position, force, etc.) the Press-Right removes the GO
signal.
After removing the GO signal, the instrument continues to control the curve until either the force and
height begin to decrease and the cylinder retracts. This is provided with the signal of good or bad
piece.
If the piece is good, the OK output is activated. Conversely, if the piece is rejected, the KO output is
activated.
The correct zeroing of the encoder takes place using its zero signal and the TDC back cylinder
signal.
1.3 Internal cards
The Press-Right is made up of two electronic components:
PR2MB2 front panel this component mounts the display, the keyboard, the memory and the
CPU.
VIO10 Input and output the digital input and output, the transducers and the communication
port are connected to this card.
All cards are made by us.
1.4 Electrical wiring
The following information is needed to carry out the electrical wiring of the instrument.
1.4.1 Information for connecting to an external controller (PLC)
The PLC connected to the Press-Right must be PNP positive logic. The inputs and outputs of the
instrument are isolated and protected and consequently there is no need for interfacing relays.
The essential signals for operation are START, GO, OK and KO.
Remember that in all cases it is always necessary to connect the TDC input of the instrument. The
TDC signal can be taken directly from a limit switch activated with the press in rest position. When
the press signal in the rest position is also needed by the PLC, the signal to be supplied to the
instrument can be taken in parallel with the one connected to the PLC.
