6.1 Replacing the 0721.1 with 0721.2, .3 or .4
The counter 0721.2, .3 and .4 replaces the old counter 0712.1. They only differ as to their displays.
The counter is designed with completely new hardware. Therefore the wiring of the plug type connectors
changed as well. For more information on these changes please see chapter 6.2
For the power supply has to be considered:
The connections for the DC supply are still 1 and 2. But they have been changed among each other.
New is, that now 10 = +UB and 2= 0V
The AC- power supply is connected to 9 and 10.
Danger!
Under no circumstances, the connector with the old wiring is allowed to be
plugged to the new counter. A wrong connection may lead to dangerous situations,
extensive material damage and the destroying of the counter.
