The control terminal may be connected and disconnected while the timer
is running.
Communication with the timer is automatically established when X2 has
been linked, if the BT 6.00 power supply (X1) had previously been inter-
rupted.
If the BT 6.00 power supply had not been previously interrupted, the
BT 6.00 signals that communication with the weld timer is not possible.
In this case, simply press the
key on the BT 6.00 in order to establish
communication.
