1 Introduction This manual describes the operations necessary to connect the machine to VISUAL POINT. There are two versions of VISUAL POINT: for external mounting and for panel mounting. The panel version is only available with 24VDC power. The external mounting version is available in versions: 24VDC or 100-240VAC.

Picture 2 2.1 Operating of the instrument Attention: the VISUAL POINT is not (and could not be) a safety device: the descent of the press must be entrusted to external elements. The VISUAL POINT synchronises the descent for its operation. The GO Output is usually connected serially to the chain of the cylinder descent. In...
2.2 Information for connection to an external controller (PLC) To connect the VISUAL POINT to a PLC, the latter must have PNP positive logic. The inputs and outputs of the instrument are opto-isolated from the instrument’s control electronics. The power supply of the instrument’s inputs and outputs must be the same that powers the inputs and outputs...
2.3.2 Serial port terminal (CONN1) Only present in version with cabinet for external mounting. On the back of the VISUAL POINT is a D-Sub 9-male for the RS232 serial connection. The connector pin-out is as follows: Pin 2: RX input line of Visual Point.

2.5 Instructions for assembling the instrument with cabinet picture 4 To open the container with VISUAL POINT unscrew the four screws in the corners of the back and front panel. Dismantle the groups of terminal blocks. Pull out the electronic boards from the front (Figure 10).
2.8 SETPOINT output The VISUAL POINT SETPOINT has an exit which is normally activated when the share is measured starting (see user manual) and is off when the value of arrest. This can be used to start the phase of work, after the phase approach.
