ALARM Description
4.1
The signal of the unlocking switch stays off during the unlocking phase:
-unlocking pressure too low;
-bad position of unlocking switch;
-bad switch connection/wiring (remote application mainly);
-the unlocking switch is defective.
4.2 The signal of the unlocking switch goes off while the turret is unlocked:
-problems of pressure;
-bad switch connection/wiring (remote application mainly);
-the unlocking switch is defective.
4.3 The signal of the locking switch goes on while the turret is unlocked:
-problems of pressure;
-bad switch connection/wiring (remote application mainly);
-the locking switch is defective.
4.5 The two pressure inlet or the LOCKED and UNLOCKED switches are reversed.
No pressure, the clamping mechanism does not move at all.
5.0 The signal of the unlocking switch stays on during the locking phase:
-locking pressure too low (only hydraulic);
-bad position of unlocking switch;
-bad switch connection/wiring (remote application mainly);
-the unlocking switch is defective.
5.1
The signal of the locking switch stays off during the locking phase:
-locking pressure too low (only hydraulic);
-bad position of locking switch;
-bad switch connection/wiring (remote application mainly);
-wrong control unit /software (card for a different size);
-wrong reference cam regulation (turret lock over teeth);
-the locking switch is defective.
5.2 The signal of the locking switch goes off while the turret is locked:
-problems of pressure (only hydraulic);
-bad switch connection/wiring (remote application mainly);
-the locking switch is defective.
5.3
The signal of the unlocking switch goes on while the turret is locked:
-problems of pressure (only hydraulic);
-bad switch connection/wiring (remote application mainly);
-the unlocking switch is defective.
5.5 The two pressure inlet or the LOCKED and UNLOCKED switches are reversed.
No pressure at all.
6.0
Time-out in reference search:
-the zero switch is defective (always off);
-the position of the reference cam is wrong ;
-bad switch connection/wiring (remote application mainly);
-the disc cannot rotate.
6.1 Time-out in fine reference search:
-the zero switch is defective (always on);
-bad switch connection/wiring (remote application mainly);
-the disc cannot rotate.
7.0 A tool is called before executing the zero cycle:
-error in programming logic of CNC;
-the operator did not call the reference cycle.
7.1 Parity Error in position code:
-error in programming logic of CNC;
-problems on wiring (PBIT** and PARITY)
-slow outputs of CNC/PLC (the output value van be incorrect when the PSTART signal is given)
7.2 A tool non existing has been called:
-error in CNC programming;
-turret not correctly configured (check the number of positions set by PTAB01 and PTAB02 signals - LK1 and LK2 in
connection box);
-wiring problems.
7.3
A variation in position code has been detected but the PSTART signal is not arrived in within 5 seconds:
-error in CNC programming;
-wiring problems (PSTART signal not connected).
7.4
The time limit of continuos rotation of disc has been reached:
-the turret has been activate in maintenance mode or service for long time;
-the indexing frequency is too high.
7.8 or 7.7
The configuration input signals PTAB01 and PTAB02 are not configured (number of positions):
-error in PTAB01 and PTAB02 setting (LK1 and LK2 in connection box);
7.11, 7.12,
7.13, 7.14,
7.15
One of the Internal memory tests failed.
If the alarm persist after a switch-off/switch on, replace the controller.
Note: the code number is memorised by the control unit and can be read with a Duplomatic diagnostic
software DDC4SW*.EXE installed on a PC with the RS232 interface. Communication parameters are
