3.7 – ALARM

The MASS-tron II/CEM Alarm Option provides the means for having the process signal compared to a user selectable
Low Flow alarm point and automatically activates a Form C relay to generate a dry contact alarm signal.  Alarm On/Off,
Setpoint, Dead Band, and Delay are configurable via the Operator Setup menu.  Alarm Setpoint can be displayed on
during 

Normal

 operating mode.  An Alarm Delay is available, if implemented (any time setting greater than zero), any

condition that would normally cause an alarm, triggers the delay timer first.  If the alarm condition still exists after the
delay times out, then the alarm relay is activated.

3.8 – DATA DISPLAY

The integral display is a graphical backlit LCD.  It is capable of displaying the transmitter flow, process temperature and
static pressure signals in Engineering units, plus other signals of alarm or AUTO-cal functions.  It can also display a
user settable I.D. number using any combination of standard ASCII characters.  It is also used by the Operator Setup
menu for displaying the menu parameters and values.  Configuring the display for 

Normal

 operation is done using the

Operator Setup menu.

3.9 – K-FACTOR

The MASS-tron II/CEM is equipped with a K-Factor feature which allows for the introduction of a bias and/or gain factor
into the transmitter's flow calculations.  The K-Factor feature is intended to be used in two types of applications:

1. To adjust for flow measurement error as a result of highly distorted airflow induced by upstream or downstream flow

disturbances.

2. To adjust the transmitter's output to bring it into close correlation with field measured flow data.

The K-Factor gain and bias values can be entered directly or the MASS-tron II/CEM can calculate these values based
on measured and reference values from a 1 or 3 point airflow traverse.

3.10 – FLOW/DIFFERENTIAL PRESSURE CALCULATOR

The MASS-tron II/CEM is equipped with an integral calculator feature that allows the user to determine the maximum
flow or differential pressure from the appropriate variables.  This feature allows the user to determine input or output
values at various points of the process or new values if the process parameters have changed.  Also, the calculator can
be used to implement a single-point density compensation for operating temperature and/or absolute pressure.

3.11 – NETWORK (option)

The MASS-tron II can be provided with optional ModBus TCP/IP over Ethernet for serial data communication.

3.12 – MULTIPLE OPERATING POWER SELECTIONS

The MASS-tron II/CEM can be powered by 24VAC or 24VDC, or 120VAC with optional transformer.

3.13 – ENCLOSURE

The MASS-tron II/CEM transmitter is furnished in a NEMA 1 aluminum enclosure with external, unitary plug in terminal
strips for ease of installation and removal.  An optional conduit connection box is available for applications requiring
enclosed field wiring.
