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 Statement 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.
Output error Error during cyclical output test for
short circuit. Possible causes:
Short circuit, or output defective. Rectify the short circuit or change
the faulty module.
Error in the (local) enable principle FS output has reacted incorrectly
or unexpectedly
Check configuration.
( 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.
