Description
CAL DP2 AVG
41
702, 704
Represents the average value of DP2 RAW (Point 88) for the
period of time set in CAL TIME (Point 44). DP2 RAW is sampled
for averaging when CAL DP2 (Point 43) is set to DONE. When
CAL TIME has elapsed, the average value of DP2 RAW for this
time period will be displayed in this field.
CAL DP1
42
701, 702,
703, 704
The operator sets this point to DONE to initiate the field
calibration procedure. The point will return to READY when
CAL TIME (Point 44) has elapsed.
CAL DP2
43
702, 704
The operator sets this point to DONE to initiate the field
calibration procedure. The point will return to READY when
CAL TIME (Point 44) has elapsed.
CAL TIME
44
701, 702,
703, 704
Indicates the amount of time the differential pressure raw values
are sampled during calibration.
Valid entry:
0-600 seconds.
RED LED
45
701, 702,
703, 704, 790
Digital output used to turn on and off the red LED.
GREEN LED
46
701, 702,
703, 704, 790
Digital output used to turn on and off the green LED.
HORN
47
701, 702,
703, 704, 790
Digital output used to turn on and off the horn.
HORN SILENCE
48
701, 702,
703, 704, 790
Determines the mode of operation for the HORN when an alarm
is active.
LOOP SIGNAL
49
701, 702,
703, 704, 790
4-20 mA linear signal output, over the range of -0.2 to +0.2
inches of water (-49.8 to +49.8 Pascals), used to represent the
pressure for DIFF PRES1 (Point 30).
ALARM OUT
50
701, 702,
703, 704, 790
Digital output used to turn on and off the alarm output.
MAX1 POS
51
701, 702,
703, 704
Represents the field calibration differential pressure, as read from
DP1 RAW (Point 68), when the Remote Pressure Transmitter
calibrator is set to the MAXimum differential pressure (+0.170 in.
of water, 42.34 Pascals) for positive pressurization.
MID1 POS
52
701, 702,
703, 704
Represents the field calibration differential pressure, as read from
DP1 RAW (Point 68), when the Remote Pressure Transmitter
calibrator is set to the MIDdle differential pressure (+0.050 in. of
water, 12.45 Pascals) for positive pressurization.
MIN1 POS
53
701, 702,
703, 704
Represents the field calibration differential pressure, as read from
DP1 RAW (Point 68), when the Remote Pressure Transmitter
calibrator is set to the MINimum differential pressure (+0.005 in.
of water, 1.24 Pascals) for positive pressurization.
ZERO 1
54
701, 702,
703, 704
Represents the field calibration differential pressure, as read from
DP1 RAW (Point 68), when tape is applied over the Remote
Pressure Transmitter through-the-wall ports producing a zero
differential pressure (+0.000 in. of water, 0.000 Pascals).
MAX1 NEG
55
701, 702,
703, 704
Represents the field calibration differential pressure, as read from
DP1 RAW (Point 68), when the Remote Pressure Transmitter
calibrator is set to the MAXimum differential pressure (-0.170 in.
of water, -42.34 Pascals) for negative pressurization.
