Signature Class
If you are transacting business with a bank that is EBICS T compliant, then Signature Class should be set to Transport signature (type 'T'). If you are transacting business with a bank that is EBICS TS compliant, then Signature Class should be set to Single signature (type 'E'). Note that the A and B signature classes, as defined in the EBICS specification, will not be supported until VEU is fully supported. See EBICS Overview.
Note:

Referring to the EBICS specification and the ebics_signature.xsd schema (found at www.ebics.org), it appears that the element <OrderSignatureData> is unbounded within the <UserSignatureData> element. At this time, the VersaLex EBICS client supports only one instance of  <OrderSignatureData>. 

The bank server will maintain a record of your partner and user ID, along with your associated signature permission level. The mechanism the bank uses to obtain and initialize these records is outside the scope of the Cleo VerasLex EBICS client.

The EBICS specification requires that the certificate used for ES is different from the certificate used for identification and authentication and encryption. See EBICS Overview. See EBICS Mailbox: Certificates Tab for information about defining identification and authentication certificate and the encryption certificate.
