During the check phase, if the sequence is correctly executed, each LED will be on when
the corresponding input is in ON state. When the check is ended and the result will be
positive, the LEDs: PMSM, AV, VSA will turn off and will assume other functions during the
normal operating cycle. The YELLOW-BLUE LED will be instead on and will assume the
function of indicator of the alignment between TX and RX.
In case of failure of the stop space check, the device will lock, setting the OSSD outputs to
the permanent state OFF, one or more LEDs will blink depending on the type of occurred
error, the RED LED will remain turned on.
Types of errors when the LED AV blinks
- when the mobile table has been moved to PMSM and the limitswitch VSA is in state OFF.
- when, after that the mobile table has been moved to PMSM and then the check is started,
the HIGH SPEED signal has gone to state ON and then has come back to state OFF before
the limitswitch VSA has been intercepted.
- when, after that the mobile table has been moved to PMSM and then the check is started,
this, going down at slow speed, causes the interception of the limitswitch VSA with the
HIGH SPEED signal in state OFF.
Type of error when the LED PMSM blinks
- when, after that the mobile table has been moved to PMSM and then the check is started,
its signal passes from the ON state to the OFF state without the HIGH SPEED signal has
passed to ON state.
Type of error when the LED VSA blinks
- when, after that the mobile table has stopped due to interception of the limitswitch VSA,
the signal of this comes back again to ON state because the cam has gone beyond it
causing the failure of the check.
12.1.2. Display of the alignment with four LEDs
In the check phase, the PMSM input is set to ON state, with its LED turned on which points
out the mobile table has reached the position of PMSM, after this phase, it activates
instead, in this condition, the function of display of the alignment by four BLUE LEDs.
In order to activate this function, it is necessary to move the mobile table up to intercept the
limitswitch PMSM and, in this condition, besides the LED PMSM, the four BLUE LEDs turn
on steady if all the receiving elements will be illuminated by the laser light of TX or all
blinking if none of them is illuminated. If the laser light will illuminate only apart of them, the
blinking of one or more LEDs will point out the direction where the laser light must be
moved.
12.1.3. Alignment LED
Once ended the check of the stop space, when all the receiving elements correctly receive
the laser emission, the YELLOW-BLUE LED will turn on to signal that the device is aligned
and that all the receivers are correctly receiving, while its turn-off will signal that at least one
receiving element is intercepted.
12.1.4. Display of the lock after 30 operating hours
If the DSP LASER device, and then the machine which it is connected to, operates for more
than 30 hours without interruptions, the system activates a locking function which sets the
outputs to the permanent status OFF. This locking status is signalled by the RED, GREEN,
YELLOW-BLUE LEDs which turn on in sequence. The deactivation of this function is
possible only cutting the power supply to the device. Doing so, on the new switch-on, DSP
LASER forces the machine to execute the check of the stop space. Doing so, the
