Example Enable fault diagnosis output. Disable reflash
and AND operations. Set the relay operation to
energize and hold. Set the alarm status display
to hold. Set the interval for the high limit of rate-
of-change alarm to 10, the interval for the low
limit of rate-of-change alarm to 12, the
measurement alarm hysteresis to 0.5%, and the
computation alarm hysteresis to OFF.

Description • The interval for the high limit of rate-of-change
alarm is equal to “scan interval
×
p7” and the
interval for the low limit of rate-of-change
alarm is equal to “scan interval
×
p8.”
• Parameter p10 can be specified on models
with the computation function (/M1 option).
• For the details on the settings, see the
µ R10000 Recorder User’s Manual or the
µ R20000 Recorder User’s Manual .
XI Sets the A/D integral time.
Syntax XI p1 <terminator>
p1 Integration time of the A/D converter
AUTO Automatically set in synch with
the power supply frequency.
50HZ 20 ms
60HZ 16.7 ms
100MS 100 ms (dot model)
Query XI?
Example Set the A/D integral time to 50 Hz.
XI 50HZ
Description • 100 ms is available only on the dot model.
• If Auto is specified when using the 24-VDC
power supply on a recorder with the 24-VDC/
AC power supply (/P1 option), the integration
time is fixed to 20 ms (50 Hz).
XB Sets the burnout detection.
Syntax XB p1,p2 <terminator>
p1 Channel number
p2 The procedure taken when a sensor
burnout is detected
OFF Disable the burnout detection.
UP Set the recording off the scale to the
right when a burnout is detected.
DOWN Set the recording off the scale to the
left when a burnout is detected.
Query XB[ p1]?
Example Set the recording off the scale to the right when a
sensor burnout is detected on channel 01.
