1) Depending on the voltage supply used, an overcurrent can also result in the voltage supply dropping out. 2) Reset of the error: set the process data bit of the safety output to 0. 3) Reset of the error: the process data bits for all safety outputs of the module are simultaneously 0 and the
output level is Low. 4) In the case of a High instead of a Low on a safety output, the supply to all safety outputs is switched off
internally. If the cause of a short-circuit is in the wiring to 24 V, then the affected signal remains High and all other signals switch to Low. Check if this is an undesired but valid signal value for the receiver, e.g., for the switching of the monitoring case of a SICK safety laser scanner by means of a complementary signal. 5) Depending on the size of the capacitive load, this may lead in certain cases to an incorrect interpretation as an internal error since the effect on the output voltage is only temporary.

Critical error status
Consequences of the critical error status:
· All applications are stopped. · All safety outputs are switched off. · All process data = 0 · Evaluation of the process data status bits in the logic is no longer possible. · Only limited diagnostics can be performed in the critical error status.
Alternatives to resetting the critical error status:
· Restart by switching the voltage supply off and on again · Software reset using the configuration software

1) If you are using single-channel safety outputs (Q) for a safety-related application, then a protected or separate cabling is required for these safety outputs in order to achieve the safety-related characteristics. Reason: While short-circuits to the supply voltage or cross-circuits to other outputs can be detected, no other option to switch-off the device exist.
2) If you are using single-channel or dual-channel safety outputs (Q) without test pulses, then a protected or separate cabling is required for these safety outputs in order to achieve the safety-related characteristics. Reason: Short-circuits to the supply voltage or cross-circuits to other outputs are not detected in the switched-on state without test pulses. This also applies if an output is used for a non-safety related application. Reason: Even if an internal hardware error is detected, the switch-off capability of the other safety outputs may be impaired by reverse currents.
3) If you are using single-channel/dual-channel safety outputs (Q) without test pulses for a safety-related application, then one of the following measures is required in order to achieve the safety-related charac- teristics:
· Restart the safety controller once a year. · Manually switch off all safety outputs simultaneously for min. 2 s once a year. The supply voltage to
the outputs must be within the operating range during this manual test.

1) Take into account the following when designing the voltage supply for the safety controller:
· Current consumption at nominal voltage (without outputs) of all station modules · Peak current consumption of all electric consumers connected via the safety controller outputs
The maximum permissible supply current depends, amongst other things, on the ambient temperature and must not exceed the permitted value of 8 A (Ta = 55 °C). Take into consideration the effect of lack of ventilation or the power loss in cables or other devices on the ambient temperature in the control cabinet.

2) Higher voltages are evaluated as a cross-circuit fault 3) In the event of a fault (GND line open circuit) and with a load resistance of at least 2.5 k, no more than
the specified leakage current flows on the safety output. For lower load resistances, the leakage current may be greater however the output voltage will be < 5 V in this case. A downstream device, for example a relay or a FPLC (fail-safe programmable logic controller) must detect this state as Low. 4) When activated, the outputs are tested regularly (brief switching to Low). When selecting the downstream control elements, ensure that the test pulses with the specified parameters do not result in a switch-off, or deactivate the test pulses on the outputs yourself. 5) Safety outputs (Q) with test pulses only detect cross-circuits reliably (i.e. already in the switched-on state and not just after a switch-off) if these values for the supply cable and the connected control element are not exceeded. Otherwise further measures will be required, for example protected or separate cabling. (See also EN 60204 Electrical equipment of machines, Part 1: General requirements.)
