Displayed message Description and possible remedy for the
cause
E35 24 V at OPTION output is
too high
The 24V for the external outputs I/O;
RS485; GAUGE HEAD is too high. (U >
30V)
• Check the external feed of the 24V
outputs.
• Power supply unit defective
E36 24 V at OPTION output is
too low
The 24V for the external outputs I/O;
RS485; GAUGE HEAD is too low. (U < 20V)
• Fuse F1 on I/O board defective.
• Power supply unit defective
E37 24 V power supply for the
remote control is too low (<
20 V)
The 24V for the external RC outputs and
fans 1+2 is too low. (U < 20V)
• Fuse F2 on I/O board defective.
• Power supply unit defective
E39 Temperature at electronic
unit is too high! (>60°C)
• The ambient temperature is too high.
• Unfavorable position of the leak detector.
(Heat build-up)
• Fan failed.
• Air filter too heavily contaminated.
• Temperature sensor defective.
E41 TMP frequency is too low! The target speed (1450Hz) of the turbo
molecular pump (TMP) was not reached
within 5min.
• Initial pressure of the TMP is too high.
• Turbo molecular pump is defective.
• Electronic drive unit TC 110 is defective.
E42 Emission off (p1 too high) • Inrush of air
• Valve V1 leaking.
E43 Emission off (p2 too high) Emission is switched off during normal
operation of the leak detector when the
pressure
in GROSS is p2 > (GROSS pressure
threshold + 5 mbar) or
in FINE is p2 > (FINE pressure threshold + 1
mbar) or
