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, with PSSu in system environment A
} Diagnostic log, with PSSu in system environment B.
The module can detect the following errors:
Module error Explanation Remedy
Start­up 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 in­
tegrated end bracket or insert the
base modules together correctly.
Temperature error: too warm ( 1 ) Ambient temperature too high:
Error stack entry/diagnostic log
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/O­Groups (SafetyBUS p) Ensure there is sufficient ventila­
tion in the control cabinet or pre­
vent overload.
Relay control error Error during cyclical monitoring
test of the relay coils Change faulty relay module.
Relay error A relay position is faulty. Possible
cause: Defective relay contact Change faulty relay module.
Error in the local enable principle FS output has reacted incorrectly
or unexpectedly Check the configuration of the FS
output, or check the fieldbus sig­
nals in the FS and ST section.
( 1 ) There are two levels of overtemperature.
} Too warm:
If a module's temperature exceeds a threshold value, the module sends a warning to
the head module. If the temperature drops back below the threshold value, the module
sends an all­clear.
} Too hot:
If a module's temperature exceeds a further threshold value, the module sends an error
message to the head module and triggers an I/O­Group stop.
