TABLE 1-6:
• Two different gain settings for the inverter leg shunt and DC bus shunt feedback
• The Scaling and trip levels for the inverter leg shunt signals are shown in
TABLE 1-7:
• The scaling and the trip levels for the bus shunt signal is given in Table 1-8:
TABLE 1-8:
• Changing the Hall Sensors scaling is accomplished via solderable links (e.g., LK1,
are implemented via LK5-12. These are located directly under the "Danger High
Voltage" label on the PCB. The user should consult Sheet 3 of the Schematics in
Appendix A to establish which links correspond to which signal. Note that links
must be changed in pairs (e.g., LK5 and LK6 together or LK7 and LK8 together,
etc.) for correct operation (see below).
Table 1-7:
Note: The shaded setting should not be used, as it will not adequately protect the
LK2 and LK3 for U1). These are located adjacent to the transducers. The links
change the number of turns that pass through the transducer over a 3:1 range.
Tinned copper wire of a suitable current rating should be used. Only one link at a
time should be used or unpredictable current scaling will occur. The user
should ensure that the maximum length of lead protruding below the PCB is 4 mm
for voltage clearance reasons. The scaling and corresponding trip levels are
shown in Table 1-9 where the links referred to are for U2.
