Output 1 (5 V logic):
The output voltage exceeds the
admissible range.
Output 2 (20-28 V printhead):
The output voltage exceeds the
admissible range.
Output 3 (galv. 24 V):
The output voltage exceeds the
admissible range.
Output 4 (48 V motor):
The output voltage exceeds the
admissible range.
Dot Check defective:
Indicates a detected power supply
fault in the course of a Dot-Check-
Measurement. Example: While
measuring the internal reference
resistance, have the admissible
tolerances been exceeded.
Fan defective:
Indicates a fan-fault, if its control
allows any error detection.
Critical overheat:
A critical temperature is set in
register "critical temperature limit". If
the critical value is exceeded, the
power supply switches off
immediately and sets this bit to 1.
Overheat:
A critical temperature is set in
register "critical temperature limit". If
the critical value is exceeded, the
power supply switches off well
controlled and sets this bit to 1.
