A module error is displayed via the “Err” LED (see section entitled “Display elements”), sig-
nalled to the head module and then entered in the head module's error stack.
The module can detect the following errors:
Module error Explanation Remedy
Start-up error Error as the PSSu system starts
up
Change faulty module.
Configuration error Incorrect module type configured. The configured hardware registry
does not match the actual hard-
ware registry.
FS communication error Error during FS communication Change faulty module.
Bus termination error There is no terminating plate or
there is a bad contact with the
module bus.
Install a terminating plate with inte-
grated end bracket or insert the
base modules together correctly.
Temperature error: Too warm ( 1 ) Ambient temperature too high:
Error stack entry
Ensure there is sufficient ventila-
tion in the control cabinet or pre-
vent overload.
Temperature error: Too hot ( 1 ) Ambient temperature too high:
Reset the module and stop the af-
fected I/O-Groups (SafetyBUS p)
Ensure there is sufficient ventila-
tion in the control cabinet or pre-
vent overload.
Overvoltage error A system voltage or infeed is too
high.
Stabilise the supply or change the
faulty supply voltage module.
Undervoltage error A system voltage or infeed is too
low.
Stabilise the supply or change the
faulty supply voltage module.
Relay control error Error during cyclical monitoring
test of the relay coils
Change faulty module.
Block switching output error Error during cyclical monitoring
test of the relay contacts. Possible
external cause: Voltages being fed
back to the relay contacts
Check the supply voltage and the
wiring.
( 1 ) There are two levels of overtemperature.
} Too warm:
If a module's temperature exceeds a theshold value, the module sends a warning to the
head module. If the temperature drops back below the threshold value, the module
sends an all-clear.
} Too hot:
If a module's temperature exceeds a further theshold value, the module sends an error
message to the head module and triggers an I/O-Group stop.
Further information on PSSu error messages is available in the online help for the PSS
WIN-PRO system software.
