Operation
D1 – Flow Rate Units
Setting the maximum and minimum flow rate threshold
values will provide an alarm to alert you that the pro-
cess is out of specification.
Select liters per minute (L/min), cubic centimeters per
minute (cc/min), or ounces per minute (oz/min) for
units of measure. The default setting is cc/min. Follow
the same process as setting the A1 parameter.
cc/min
L/min
oz/min
D2 – Flow Rate Maximum Threshold Value
Follow the same process as setting the A2 parameter.
The default setting is 0.
cc/min
D3 – Flow Rate Minimum Threshold Value
Follow the same process as setting the A2 parameter.
The minimum threshold value should be no less than
22 * K-factor. The default setting is 0.
E1 – K-factor
The K-factor setting is the scale factor for the meter
and is specified in units of cc/pulse. The valid range for
K-factor is 0.010 cc/pulse to 1.000 cc/pulse. The
default setting is 0.120, which is the K-factor for the
meter.
cc
Alarm Outputs
The next series of setup parameters allow you to
enable (1) or disable (0) the alarm outputs. If the alarm
outputs are enabled, the Informer display will send a
signal to turn on an external alarm to signal an alarm
condition. The default setting for all the alarms is
disabled (0).
F1 – Batch Totalizer Alarm Enable
If enabled (F1=1), the batch alarm output is activated
when the batch totalizer reaches the target (if the
batch totalizer type is count up) or reaches zero (if the
batch totalizer type is count down).
F2 – Diagnostic Alarm Enable
If enabled (F2=1), the user alarm output will activate
when the diagnostic status is a non-zero value. The
diagnostic status will repeatedly flash on the screen in
Run Mode until the fault is corrected.
For example, the display will show E=1 for a diagnostic
status of 1. The following is a list of diagnostic status
codes:
Diagnostic Status Codes
E = 1 Invalid node address: The Modbus
network node address is set outside the
valid range of 1 through 247.
E = 2 Invalid K-factor: The K-factor is set out-
side the valid range of 0.010 cc/pulse to
1.000 cc/pulse.
E = 3 Invalid Batch Totalizer Type: The Batch
Totalizer Type is set to a value other than
t1, t2, or t3.
E = 4 Invalid Flow Rate Threshold: The Flow
Rate Minimum Threshold value is greater
than the Flow Rate Maximum Threshold
value.
