10.3 Error from the extended functions (0x40 to 0x9F)
0x40
ERROR_FANDEFAULTS ? In the curve segment, a fan default is
predened, which is smaller than the mini-
mum speed or higher than the maximum
speed of the fan (P26 or P27).
P26 (min. speed) is 500 U/min but the
speed for modulation degree 0% is set
to 480 rpm. Or P27 (max. speed) is set to
5600 rpm but the pre-aeration B should be
carried out with 5800 rpm.
0x41
ERROR_FAN_DEVIATION ? The number of pulses in the fan feed-
back is set to an incorrect value
? The fan is not suitable for the desired
speed
? The predened tolerance is too low or
the fan controller is not optimised
0x42
ERROR_FAN_NO_FEEDBACK ? The feedback line of the fan is not cor-
rectly connected or is interrupted
? The fan is blocked and does not work
? The fan is not supplied with power or is
defective
0x43 ERROR_TEST_IONISATIONINPUT
0x44
ERROR_CURVECRC16_TEST ? The curve segment was temporarily
changed, for ex. for putting the MPA into
operation, and was not correctly enabled
later
0x45 ● ERROR_INVALID_MODULATIONDEGREE ? Modulation degree is outside the limits
0x46 not used
0x47 ● ERROR_INVALID_STEPPEDMOTORTYPE ? Check stepped motor (compare P30)
0x48
ERROR_STEPPEDMOTOR_TOLERANCE_EX-
CEEDED
? The lines to the stepped motor are not
correctly connected or partly interrupted
? The stepped motor is charged with more
than the admissible torque, for example
due to improper mounting of the ap or
pressure impulses.

ERROR_PARAMETERRECORDSTICK_NOT_
FOUND
? Parameter record activated but not
plugged in the MPA
? Stick defective
? Duration of the standard mode (P70) is
higher than 23 h 59 min and the continu-
ous run is not enabled
? PWM outputs congured to analogue
operation (0..10 V or 4...20 mA) but no suit-
able stick is plugged in.
