14.1. Power supply of the device
•
Once connected TX and RX and if present the AL module and the other signals
necessary to the operation of DSP LASER system, depending on the model of RX and
AL, energize the system. TX will emit laser light and, on RX, some LEDs will result on,
as described in paragraphs of 12.1.
•
Execute the mechanical adjustment of TX and RX to collimate them and set the
protection area correctly on the machine.
To execute the adjustment, act as pointed out in
13.2 Adjustment .
•
Be sure the two OSSDs are in state OFF. If RX would be configured without the
function of the Check of the Stop Space, the two OSSD outputs would be in state ON. In
this case stop the collimation (for example, putting an opaque object between TX and
RX in the detection area).
- When the system configuration is without AL module or with AL1B, the check is
possible verifying the lacking of potential on the solid state OSSD outputs, using a tester
as voltmeter in cc e measuring between 0Vcc and OSSD1 and then between 0Vcc and
OSSD2.
- When the system configuration is with ALdc or AL2B, the check is possible verifying
the lacking of continuity between the contacts of the OSSD outputs using for example a
tester as ohmmeter and measuring first between two OSSD 1 CR clamps and then
between the two OSSD 2 CR clamps. The instrument must point out, in both cases, a
value of infinite resistance corresponding to a condition of open circuit.
•
Connect the outputs of the two OSSD in the points foreseen by the electric circuit of the
press.
14.2. Adjustment after the installation
For the first installation, the device must be adjusted. For this purpose, the test and
positioning instrument is provided with DSP LASER.
Fig. 14.1 Test and positioning instrument
Set a low closing speed, lower than or equal to 10 mm/sec. Lay the test and positioning
instrument over the lower tool at
point A (near TX) of Fig. 14.3. Lower the upper tool until
its tip brushes against the notch present in the vertex of the groove of the upper part of the
tool laid on the die, as in Fig. 14.4.
