Distinctive features

For Master/Slave installations, note that the commissioning differs from that of the standard
DFA as follows:
▪ The operators of a Master/Slave installation must be connected together via the commu-
nication line and the CAN-isolator 102-127808247 (see Master/Slave circuit diagram in
this user manual).
▪ With the operators of a Master/Slave installation, the CAN bus terminating jumper J13
must be set to Master/Slave (see Master/Slave circuit diagram in this user manual).
▪ The actuation devices must be connected to the master. AKI, AKA and SSK will be ig-
nored by the slave.
▪ Safety actuation devices (SIO, SIS) that are mounted on both door leaves must be con-
nected to the corresponding operator, i.e. the SIS on the slave leaf must be connected to
the slave drive.
▪ Electric locks and possibly present locking contacts (VAK) must be connected to the cor-
responding operator, i.e., the electric lock on the master leaf must be connected to the
master drive.
▪ Using jumper J14 on the STG 127, one operator is set as master and the other slave.
The operator of the active door leaf must always be selected as the master (see Mas-
ter/Slave circuit diagram in this user manual).
▪ The current feed to both operators must either be switched on simultaneously, or the sla-
ve must be switched on first.
▪ The calibration run is carried out individually for each operator. During the calibration run
of the slave, the master opens as well, so that the slave will not be obstructed.
▪ The opening and closing speed is the same for both operators, and the value is transmit-
ted from the master to the slave. The opening time delay is also specified by the master
in the same way. If these values are to be modified, they must therefore be set on the
master operator; the slave will take over the values immediately.
▪ The opening angle and automatic reverse can be set separately at each operator. See
about the settings in the parameter list.
▪ If one of the operators should fail, it is recommended that the second operator should al-
so be disconnected from the power feed. Both operators can then be restarted normally
as described above.
▪ Special function for overlap, opening and closing sequence.
