OPERATING FUNCTION N °7: SAFETY
The standard behaviour of the turret can be changed in order to allow the turret to work even if
there are problems mainly on proximity switches.
WARNING: all the functions are intended to be used only in case of effective problems.
The improper use can cause a damage of the turret or the machine.
Proceed as follows:
1. Clear all alarms (if present);
2. Set the operating function:

4. Set the PSTART signal two times (with a pause of about 50ms. between the two pulses)
without changing the code pattern to activate the function required.
IMPORTANT: there is no confirmation about the correct execution of the operation, because this
is intended as a manual operation with effect that can be easily verified by operator.
All functionality set by this mode will be automatically reset at the power-off of the control unit.
(1) This is an alternative way to execute the reference cycle in CNC in which the tool T 0 is not
allowed. In this case only one PSTART is required.
(2) In this case we assume that the turret is surely locked or unlocked in about 400 ms.
(3) Be sure that the disc is really in position 1, elsewere this operation could be dangerous.
This function can be performed only if the reference cycle has not yet been executed.
(4) Please be sure that thermal detector is broken otherwise this could damage the servomotor.
(5) The second digit of the alarm code is output on the ALBIT1..ALBIT4. A reset will turn-off this
function.
