TESTING THE RESOLVER INTERFACE
•
SWITCH ON:
o
Data LEDS LD7 and LD 4 will flash at least once per second
o
Status LED LD5 will be green if it detects good 1:1 ratio resolver signals.
If it detects bad signals LD5 will flash red and green.
LD1 should be on, indicating reference voltage detected.
o
Status LED LD6 will be green if it detects good 30:1 ratio resolver signals.
If it detects bad signals LD6 will flash red and green.
LD1 should be on, indicating reference voltage detected.
o
LD3 will flash in time with data input from the log or external device.
It is important that this is just a brief flash once per second. If excessive data is applied the
delivery of heading data will be interrupted.
•
POWER & DISTRIBUTION INTERFACE
o
LD2 indicates the 24v nominal power for the repeaters is on.
o
LD1 shows data coming in from the KW910-X2
o
LD4 is on showing the 5 volts is present for the data output drivers
o
To test each individual output you can connect an LED across pins 3 to 5 of each output terminal.
o
The data output will be read by the repeaters and displayed.
CHECKING RESOLVERS FOR ALIGNMENT
1. Repeaters will indicate the heading. Use a display with 2 decimal places during the tests, or use a PC to display
the raw data which contains heading to 3 decimal places.
2. Move the gyro and check that the interface follows in the same direction. Hopefully it does, and the heading is
also nearly exactly that of the gyro.
3. If not, then the resolver is not wired in the standard way. You will have to try different tests and adjustments to
make it so. Here is some guidance. You can not proceed until the data is nearly correct, and to do that logically
you will have to use a PC to display the data.
CHECKING THE DATA AND ADJUSTING PHASING
1:1 RESOLVER PROCESSOR
•
Read the data at TP1.
•
Alternatively read the data at SK3 and use the hex data as will be described later.
•
The heading should equal that of the gyro, or be within a few degrees.
o
Recalling, that you have already checked for zero volts on S1-S3 at zero degrees perhaps the phasing
is wrong.
o
Try reversing a pair of wires and try again.
o
You can always prove the interface by simply removing one phase and allowing a small voltage to
remain on the other phase. At this point a recognisable angle.
•
Once you have proved that the 1:1 processor delivers correct heading you can proceed.
30:1 RESOLVER PROCESSOR
•
Read the data at SK3 or TP2 and use the hex data as will be described later.
•
Ignore the FINAL heading and check that the FINE SECTOR angle is appropriate within a few degrees. (Divide
by 30.)
o
This fine sector data is in hex format in the 2
nd
data field of the long data sentence.
•
Example 1:1 heading = 000. Fine angle = 180 = 006 sector degrees. Final heading = 006.
o
Recalling, that you have already checked for zero volts on S1-S3 at zero degrees perhaps the phasing
is wrong.
o
Try reversing a pair of wires and try again.
o
You can always prove the interface by simply removing one phase and allowing a small voltage to
remain on the other phase. A recognisable angle results.
