Chapter 3 – Point Database
Descriptor Address Application Description
DP2 RAW 88 702, 704 Indicates RAW counts used for diagnostic purposes.
SWITCHOVER 89 701, 702,
703, 704
Indicates that the controller is switching from one pressure mode
to another. This point will turn OFF when SWITCH DELAY has
timed out.
DISPLAY DP1 90 701, 702,
703, 704
When this point is set to ON, the differential pressure reading
from DIFF PRES1 (Point 30) is displayed on the LCD.
DISPLAY DP2 92 702, 704 When this point is set to ON, the differential pressure reading
from DIFF PRES2 (Point 32) can be continuously displayed on
the LCD. Otherwise, the differential pressure reading from
DIFF PRES1 will be displayed if DISPLAY DP1 is set to ON.
DISPLAY WT1 93 701, 702,
703, 704
The factor used to filter out large changes in the value of
DIFF PRES1 (Point 30) that is displayed on the LCD. This value
is used to average a portion of the current differential pressure
with a portion of the previous differential pressure. The value of
this point is a percentage of the current differential pressure; it
will never drop below 20%.
DISPLAY WT2 94 702, 704 The factor used to filter out large changes in the value of
DIFF PRES2 (Point 31) that is displayed on the LCD. This value
is used to average a portion of the current differential pressure
with a portion of the previous differential pressure. The value of
this point is a percentage of the current differential pressure; it
will never drop below 20%.
ENG UNITS 95 701, 702,
703, 704
Toggles the display of the LCD from Inches of H
2
O to Pascals.
Toggling this point does not change the value displayed at the
Portable Operator’s Terminal.
LAMP TEST 97 701, 702,
703, 704, 790
Turns on all visual and audible user interface devices on the
DPM and energizes the alarm output.
ERROR STATUS 99 701, 702,
703, 704, 790
Status code which indicates any errors detected during controller
power-up. A status of 0 indicates there are no problems.
