When you highlight the desired alarm number in the Current

Alarms window and click Set Alarm Condition, the alarm

appears beside its number.

To remove an alarm condition, highlight the alarm and click

Clear Selected.

Note

For the accQmin flow meter, the accQcomm displays and

transmits secondary level data at 10X the actual value when

using Standard Data format. This should be considered when

setting up alarm conditions and analog outputs. This will not

occur with an accQmin using Reduced Data format.

Sampler Pacing The alarm function can signal a connected sampler to take a

sample every time a specified volume of flow is reached.

In the Sampler Pulse box, select the instrument and enter the

volume at which to send the pulse. When you highlight the

desired alarm number in the Current Alarms window and click

Set Pulse Volume, the setting appears as an alarm.

A separate sampler pulse output can be set for each connected

instrument, if needed.

2.5 Outputs The accQcomm can make the flow meter data available in

several formats. Data output is configured on the Output tab.

From the Output Type pull-down menu, select either MODBUS

or Analog (4-20mA).

2.5.1 MODBUS Selecting MODBUS from the pull-down menu activates the

MODBUS settings at the bottom of the screen. Select ASCII or

RTU protocol from the pull-down menu, as well as appropriate

serial data settings.

Internal units of measure for MODBUS cannot be changed.

Parameter values will always be output as follows:
