A module error is displayed via the "Err" LED (see section entitled "Display elements"). It is
signalled to the head module and then entered in the
}
Error stack, with PSSu in system environment A
}
Diagnostic log, with PSSu in system environment B.
of the head module.
The module can detect the following errors:
Module error
Statement
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 in-
tegrated end bracket or insert the
base modules together correctly.
Temperature error: too warm (
1
)
Ambient temperature too high:

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.
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 all-clear.
