Operation

Messages

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

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 (

) 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 (

) 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.

(

) 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.
