Error message Description
F11 UF-Function The interval between the strokes of the UF2 pump was less than
220 ms. Correct delivery of the required volume is not safeguard-
ed because the stroke return travel is too short.
– A pump rate which was too high was signalled by the CPU 1.
F12 UF-Function The pulse time for the UF2 pump is less than 180 ms. Correct
delivery of the required volume is not safeguarded because the
discharge time is too short.
– Monoflop on LP 634 defect (IC 42/R65/C45).
F 13 UF-Function The pulse for the UF2 pump is longer than 500 ms. A maximum
rate of 5000 ml/h is not possible.
– Monoflop on LP 634 defect (IC 42/R65/C45).
F14 UF-Function UF2 pump not active during the test (4 s).
– Acknowledgement (UF_P2, X637/B26) → X632/C7 no LOW
pulse
– Control line (UF_P2, X634L/A–C24) → X637/B26 no LOW
pulse
F15 UF-Function The UF2 pump cannot be stopped by the CPU2.
– Control line (UF_P_EN, X632/C28) → X634R/A22 no 5 V.
– Reset input to IC 42/pin 13 on LP 634 defect.
F16 UF-Function The UF pump acknowledgement from CPU1 is faulty.
– Acknowledgement (UF_P2, X637/B26) → X633/C23 no LOW
pulse
F17 UF-Function The change in pressure after a UF2 pump stroke less than
20 mmHg.
– UF2 pump mechanically defect.
– Control line (UF_P2_CRTL, X632/B24) → X634R/C11 no
HIGH pulse.
F20 UF-Function Difference in pressure between UF pump stroke and UF2 pump
stroke more than 20 %.
– Stroke rate for UF pump or UF2 pump not set correctly.
