14.6.1 Warning messages in the log book
Tab. 12
No. Description
1 Float switch input reports feed chemical nearing an end
2 Calibration warning: Appears if the stroke length is adjusted above the tolerance and the pump
therefore has to be recalibrated
3 The number of defective strokes permitted has been exceeded
4 The diaphragm rupture sensor reports a diaphragm rupture
5 The stroke length has been modified beyond the tolerance limit with the pump locked
6 Overload warning
7 Temperature warning
8 An HMI is connected to a CANopen pump - bus operation and HMI are not permitted simultane‐
ously
14.6.2 Fault messages in the log book
Message no. Description
33 The float switch input reports no feed chemical
34 In
‘Batch’
or
‘Contact’
operating mode, a memory overload has been reached when the
memory is switched on. (Memory counter ≥ 100 000)
35 The analogue current is ≤ 3.8 mA when current monitoring is switched on. (Monitoring is always
switched on in Standard operating mode 4..20 mA).
36 The analogue current is > 23 mA when current monitoring is switched on. (Monitoring is always
switched on in Standard operating mode 4..20 mA).
37 The number of defective strokes permitted has been exceeded
38 The diaphragm rupture sensor reports a diaphragm rupture
39 The stroke length has been modified beyond the tolerance limit with the pump locked
40 Different version statuses of the CTRL, PFC and FC communication software
41 The HMI version is not compatible
42 System, EEPROM error
43 Communication between the pump and operating unit is not working although an operating unit
has been configured
44 Missing ongoing connection to the optional module
(Bus fail e.g. PROFIBUS or CANopen not active)
45 The optional module is missing or no communication is established with the optional module
46 One of the signals needed from the frequency converter (FC) is missing or no communication is
established between the FC and CTRL
46 One of the signals needed from the power unit (PFC) is missing or no communication is estab‐
lished between the PFC and CTRL
47 Over-temperature error
48 Shut-down in the event of overpressure
49 Error in the power end
50 Missing or defective position sensor
51 Mains voltage missing and/or over-/undervoltage
52 Fan error
