4 Faults and alarms
4.2 List of faults and alarms
F03001 NVRAM checksum incorrect
Message class: Hardware/software error (1)
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: A checksum error occurred when evaluating the non-volatile data (NVRAM) on the Control Unit.
The NVRAM data affected was deleted.
Remedy: Carry out a POWER ON (switch-off/switch-on) for all components.
F03500 (A) TM: Initialization
Message class: Hardware/software error (1)
Reaction: OFF1 (OFF2)
Acknowledge: IMMEDIATELY (POWER ON)
Cause: When initializing the Terminal Modules, the terminals of the Control Unit or the Terminal Board 30, an internal
software error has occurred.
Fault value (r0949, interpret decimal):
yxxx dex
y = Only for internal Siemens troubleshooting
xxx = component number (p0151)
Remedy: - switch-off/switch-on the power supply for the Control Unit.
- check the DRIVE-CLiQ connection.
- if required, replace the Terminal Module.
The Terminal Module should be directly connected to a DRIVE-CLiQ socket of the Control Unit.
If the fault occurs again, replace the Terminal Module.
A03501 TM: Sampling time change
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Reaction: NONE
Acknowledge: NONE
Cause: The sampling times of the inputs/outputs were changed.
This change only becomes valid after the next boot.
Remedy: Carry out a POWER ON.
F03505 (N, A) Analog input wire breakage
Message class: External measured value / signal state outside the permissible range (16)
Reaction: OFF1 (NONE, OFF2)
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The wire-break monitoring for an analog input has responded.
The input value of the analog input has undershot the threshold value parameterized in p0761[0...1]. p0756[0]:
analog input 0 (terminal 3/4)
p0756[1]: analog input 1 (terminal 10/11)
Fault value (r0949, interpret decimal):
Note:
For the following analog input type, the wire breakage monitoring is active:
p0756[0...1] = 3 (4 ... 20 mA with monitoring)
Remedy: - check the wiring to the signal source for interruptions.
- check the magnitude of the injected current - it is possible that the infed signal is too low.
- check the load resistor (250 Ohm).
Note:
The input current measured by the analog input can be read in r0752[0].
For p756[0...1] = 3 (unipolar current input monitored (+4 ... +20 mA)) the following applies:
A current less than 4 mA is not displayed in r752[0...1] - but instead r752[0...1] = 4 mA is output.
