F and P is only available with the corresponding sensor and the additional PCB (Art. No. 701000.000) on the SE.
Hardware Locks
LOEPFE YM 3N1 has a built-in diagnostic function. Technical problems are indicated by means of hardware locks.
Hardware locks can be cancelled by means of the unlock card, from the SCU or with button on sensing head. Since hardware
failures of this kind can have several influences on yarn quality, they should be corrected and reset by qualified personnel only.
Hardware locks should therefore be assigned to unlock card 3, which should be accessible to qualified personnel only.
A hardware alarm is indicated on the Q-sensor: Both LEDs are flashing. The type of alarm can be viewed on the SCU screen.
