Module Status Word Format (continued)
Bit Descriptions (continued)
Bit 8: In Measurement Mode –
Set to “1” when the ANR2 is in its Measurement Mode. Reset to “0” at all
other times. If this bit equals “1” when the
Module Initialized
bit is set, the ANR2 is ready to have
measurements taken on at least one of the channels. Use the Channel Status bits to determine which
channels are ready to have measurements made on them. See the
Channel Status Word Format sec-
tion on page 41 for an explanation of these bits.
Bits 7 – 4: Reserved,
These bits will always equal zero.
Bits 3 – 0: Error Codes,
These bits are set when there is an error in the programming data sent from the host.
Table 5.3 Lists the error codes and their meanings.
(Table is continued on next page.)
Error Code Name Description
0 No Error No programming errors
1 Command Error
1) There is an error in the format of the Command
Word.
2) You are attempting enter a mode that the ANR2
cannot allow at this time. For example, attempt-
ing to start measurement on a channel that is not
yet aligned.
3) You attempted to enter a mode without setting
the correct password in word 1.
4) You attempted to align both channels without
exiting Alignment Mode and saving the first in
flash. Each channel must be aligned separately.
5) Programming both the Minimum and Maximum
Values when using the One Sided Alignment or
Two Sided Symmetrical Alignment methods.
6) You attempted to program two setpoint values at
the same physical position. The sensor must be
moved before setting a different setpoint value.
7) You attempted to use the Two Point Alignment
method without writing the Write Two Point
Alignment Data command to the ANR2 while
configuring the channel.
8) You attempted to use the Two Point Alignment
method without setting both the Minimum and
Maximum Values.
9 )Attempting to program a position value while in
Two Point Alignment mode before acquiring a
signal to roughly calculate the gain.
2 Save to Flash Error
1) In Alignment Mode, you attempt to save to flash
without setting all of the required parameters.
2) An error has occurred when trying to save the
parameters to Flash. The module will set both of
the Status LED’s on red. You must cycle power
to the ANR2 to clear this fault.
3 Excitation Voltage Error
The Excitation Voltage parameter is outside of its
range of 800 to 12,000 millivolts.
4 Excitation Frequency Error
The Excitation Frequency parameter is outside of its
range of 400 to 10,000 hertz.
