Set Up and Operation
1.5.9.6
HALL OVER-CURRENT
The signals from the three Hall effect current transducers are used to provide
protection against overload, wiring and earth (ground) faults. The two inverter output
Halls (U3 and U4) are checked for both positive and negative current. The DC input
Hall (U2) is only checked for positive current. The circuitry to implement the trip is
shown on Sheet 6 of Appendix A. Being similar to that described in Section
difference is that the input signals to the comparator are divided down in order to stay
within the input voltage limitations of the comparators when running from +5V.

MODIFYING THE BOARD
1.6.1
Introduction
Certain modifications have been allowed for in the design of the system, as described
below. Clearly, any additional modifications that the user chooses to make can not be
guaranteed to be functional or safe. It is assumed that relevant qualified personnel
only will use the system.
1.6.2
Accessing The System
Before removing the lid of the system, the following procedure should be rigidly
followed:
? Turn off all power to the system.
? Wait a minimum of 5 minutes so that the internal discharge circuit has reduced the
DC bus voltage to a safe level. The red LED bus voltage indicator visible through
the top ventilation holes should be out.
? Verify with a voltmeter that discharge has taken place by checking the potential
between the + and - DC terminals of the 7-pin output connector before
proceeding. The voltage should be less than 5V.
? The system is now safe to work on.
? Remove all cables from the system.
? Remove the screws fixing the lid to the chassis and heat sink on the top and
bottom.
? Slide the lid forwards while holding the unit by the heat sink.
1.6.3
Changing Current Feedback and Trip Scaling
? Provision has been made to change the current feedback scaling of both the
isolated Hall transducers and the inverter leg and bus shunts. As the trip levels
are set at a fixed voltage, changing the feedback scaling also changes the trip
levels. Changing the scaling is accomplished in the following way:
? Follow the procedure given in Section 1.6.2 “Accessing The System” for
accessing the unit.
? Changing the inverter leg shunt sensing between unipolar and bipolar is
accomplished with LK4. LK4 is located directly under the "Danger High Voltage"
label on the PCB. Table 1-6 shows the settings:
