6.7. Fault codes
A technical failure will be signalled by the pump with a continuous alarm display and
a continuous sound. During this state, the fault code which causes the pump to fail
can be displayed by pressing the key “MODE”.
If the pump was switched OFF after a detected failure, the fault code will be stored
in the configuration of the pump (see index 380 - 389 via ARGUS service PC-tool).
The possible fault codes registered in the configuration are listed in the table below:
Fault
Code
Failure
F_21 ROM test
F_22 ROM check (Runtime)
F_23 RAM test/check
F_24 XRAM test/check
F_25 CPU test
F_26 Invalid function menu
F_27 EEPROM data invalid
F_28 RTC data invalid, no RTC etc.
F_29 Stepper motor power test (delayed 5s)
F_32 5Volt supply out of range
F_33 24Volt supply out of range (delayed 5s)
F_37 Downstream pressure sensor test failed (always > 4.7V or < 0.2V, delayed 5s)
F_38
Upstream pressure sensor test failed (always > 4.7V or < 0.2V, delayed 5s)
*
F_39 Downstream pressure sensor test failed (dynamical test failed)
F_40
Upstream pressure sensor test failed (dynamical test failed)
*
F_44 Address invalid for config-eeprom
F_45 Address invalid for history-eeprom
F_46 Frequency from uC or RTC out of range
F_47 Display-print not present
F_48 Key(s) too long active
F_49 Sensor-print not present
F_50 AIL (Air in line) detector test failed
F_51 Movement test failed (Home-Pulse < (Hall / Home))
F_52
*
Movement test failed (Home-Pulse > (Hall / Home))
F_53 More than one rotation at 'STOP' without 'KVO'
F_54 Infused sum <> Calculated sum (Rotations)
F_55 Frequency calculation
F_56 Invalid volume adjustment over time
F_57 Rotation (SW overflow)
F_58 Internal volume control (10/ml)
We recommend replacing the main board in case a fault code is not included in this
list above.
* Failure released only if configured with upstream sensor (index 51=Yes).
** Fault code F_52 may occur after a software update or if peristaltic is manu-
ally turned during service. In this case, turn the pump off then on again and
restart the pump. If a failure free start can be performed, omit this fault
code.
