No.EX##-OMY0004
The following serious errors result in the safe state:
Serious hardware faults in the internal circuit
User errors
Module overload
Module overheating
Incorrect supply
The diagnostic message is transmitted to the controller: see Section 16 “Error codes for Diagnostic
Messages”.
WARNING: Loss of safety function
Sequential errors can result in the loss of the safety function
In the event of a device error, the module should be disconnected completely from the power
supply and replaced so as to prevent sequential errors.
Parameterization errors
Parameterization errors are indicated in the following states:
Faulty parameterization
The module switches to the safe state following parameterization errors.
In the event of faulty parameterization, a diagnostic message is transmitted to the controller: see Section
20 “Appendix D”.
3.3.9. Programming data/configuration data
SMC provides device description files for various control systems.
The programming data/configuration data is defined in the device description (GSDML, FDCML, etc.)
according to the bus or network used.
3.4. Safe power supply (outputs)
The module has 4 digital outputs which can be used as follows.
Three outputs for each of the valve zones: Z1, Z2 & Z3
One output for the supply to the output modules: M.
Note this power supply switches the 24V and 0V voltage rails to the DY1 modules
Users must take all necessary precautions to avoid any external short circuits to the outputs.
Refer to EN ISO 13849-2:2012 Table D.4 Faults and fault exclusion – conductors/cables for guidance.
Caution:
Connection of the 0V to another 0V supply will bridge the safe output switch and cause a detected error.
Caution:
Connection of any output to another voltage supply will bridge the safe output switch and cause an
undetected error.
