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 feedback loop FS input detects an error in the
feedback loop or FS input is de­
fective. Check FS input, check the config­
uration of the feedback loop,
check the signals, or check the
wiring and contacts.
Error in the (local) enable principle FS output has reacted incorrectly
or unexpectedly
Check configuration.
Input error Error during the cyclical input test.
Possible cause: Input defective. Change faulty module.
Test pulse error Possible causes: Short circuit
between a test pulse and a supply
voltage, or a defective module. Rectify the short circuit or change
the faulty module.
( 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.
