aLaRmS
The UD10-DCU has a low and high alarm that are set
from the S3 configuration software and then downloaded
to the UD10-DCU. Alarm status can be viewed at the
UD10-DCU display, the EQP controller, or S3. Alarms
are non-latching at the UD10-DCU, but can be latched
using logic within the EQP Controller.
With some configurations, the alarm limits on the
UD10-DCU are tighter than on S3. If a value is out of
range, the UD10-DCU will set the value as close as
possible while remaining within the allowable range (See
Table 1). After the configuration download is complete,
the alarm setpoints can be viewed at the UD10-DCU
under Display Status->LON Config menu.
CaLIbRaTION gaS CONCENTRaTION
The calibration gas concentration is programmed
from S3 and downloaded to the UD10-DCU. See
Table 2 for calibration gas limits. NTMOS, CGS, and
PIR9400 require a gas concentration of 50% full scale.
Calibration gas concentration can be viewed from the
UD10-DCU menu under Display Status->LON Config.
