.The wiring of the safety controller must be suitable for the required safety class, (see

manufacturer documentaion).

- If the DC 24 V supply is safely disconnected at the positive pole only, no test

pulses must be applied to this pole in disconnected condition.

If the DC 24 V supply is disconnected at both poles,the test pulses must not be

applied at the same time at the plus and minus outouts. In this case,the test pulse

must be applied with a time delay.

- SEW-EURODRIVE recommends to switch off the 24 V supply at two poles.

The values specified for the safety controller must be strictly adhered to when de-

signing the circuit.

.The switching capacity of the safety relays or the relayoutputs of the safety controller

must correspond at least to the maximally permittedlimited output current of the

24 V voltage supply.

Observe the manufacturer's instructions concerning the permitled contact loads and

fusing that may be required for the safety contacts.If the manufacurer provides no

specific information,the contacts must be protected with 0.6 times the nominal value

of the maximum contact rating specified by the manufacturer.

.To ensure protection against unintended reslart in accordance with EN 1037,the

safe control system must be designed and connected in such a way that res etting the

control device alone does not lead to a restart.Arestart may only be carried out after

a manual reset of the safety circuit.

Requirements on startup

. To validate the implemented safety functions they must be documented and

checked after successful startup(validation).

Observe the limitations for safety functons in chapter"Limitations"for the validation

of the safety functions. Non-safety-related parts and components that affect the

result of the validation test(e.g.motor brake)must be deactivated,if necessary.

·For using MOVITRACMC07B in safety-relevant applicafons,it is essential that you

perform and record startup checks for the disconnecting device and for proper wiring.

Requirements on operation

Operation is only allowed within the limits specified in the data sheets.This principle

applies to the extemal safety control as well as toMOVTRACMC07B and approved

optons.

. You must check the safety functions on a regular basis to ensure proper functioning.

The test intervals should be specified in accordance with the risk assessment.
