speed stays set until the controller is inserted into the front panel socket on any machine
and the setting is changed.
The system synchronizes any machine to the encoder pulses from the next downstream
machine, to ensure that no machine will run faster than the machine which follows it in
the production stream.
The special control board obtains its input signals from a dedicated connector on the Base
Control Board (J3), and the setting of the front panel Production potentiometer. It has 2
modes: manual and automatic. In the manual mode it links the Production potentiometer
directly to the Inverter Driver; in the automatic mode it uses the signals from the Base
Control Board to determine the desired speed and the Production potentiometer will allow
a ratio of the speed to be selected (never higher than 1:1, the maximum setting of the
potentiometer).
The board has a number of different operating modes (e.g. Master, Slave and Gap
Control) and has to be configured and calibrated after installation. The explanation and
specific calibration instructions are part of the upgrade kit.
4.7 Electrical Troubleshooting and Installation Problems
Note that the following troubleshooting hints apply only to the base itself and not to
problems related to the controller and/or the print heads.
When electrical problems arise with a BK7IB-2 base, it must be remembered that it is a
part of a larger system and the problem may not necessarily be in the base at all, but could
be in the interfacing.
As a first step, make sure all equipment in the system has power and is turned on. Verify
that all cables are connected and secured.
The upstream and downstream connections on the rear of the machine are configured
differently and use different connectors to avoid confusion. An “upstream” connector (37
