HA71 Digital Gas Controller
Revision 3 (04/08)
HA71 Technical Manual 1-2
1.0 General Description
TheHoneywellAnalyticsHA71SixteenChannelControlleris designed
to display and control alarm event switching for up to sixteen sensor
data points. It may also be set as an eight channel controller for
applications needing fewer inputs. Alarm features such as ON and
OFF delays, Alarm Acknowledge, and a dedicated horn relay make
theHA71wellsuited formanymulti-pointmonitoring applications.Data
may be input to the HA71 by optional analog inputs or the standard
Modbus®RTU master RS-485 port. A Modbus®RTU slave RS-485
port is also standard for sending data to PC’s, PLC’s, DCS’s, or even
otherHA71Controllers.OptionssuchasanalogI/Oanddiscreterelays
for each alarm are easily added to the
addressable I2C bus. Option boards
have 8 channels and therefore require
2 boards for 16 channel applications.
A240x128pixelgraphicLCDreadout
displaysmonitoreddataasbargraphs,
trends and engineering units. System
configuration is through user friendly
menus and all configuration data is retained in non-volatile memory
during power interruptions.The HA71 front panel is shown below in
Figure 1.0 displaying the 8 channel bar graph screen.
1.1 Data Display Screens
The HA71 Controller offers 3 distinct graphic displays for depicting
the monitored data:
Bar Graphs•
24 Hour Trend•
Combination.•
1.1.1Trend Screen
The HA71Trend screen shown in Figure 1-2,displays a 24 hour trend
of input data for the channel selected. Horizontal tic marks are each
hour and vertical tic marks are each 10% of full scale. Dashed lines
indicate alarm levels. The graphic
LCD is 240 pixels wide so each pixel
represents 1/10 hour, or 6 minutes
worth of data.The trend is 100 pixels
high so each represents 1% of full
scale in amplitude. Since each data
point must be collected for 6 minutes
before it may be displayed, it is likely
input values will fluctuate during this
interval. Therefore, MAX, MIN and AVERAGE values are stored in
RAM memory for each 6 minute subinterval.To accurately portray the
trend, a vertical line is drawn between MIN and MAX values for each
6 minute subinterval. The AVERAGE value pixel is then left blank,
leaving a gap in the vertical line. This is demonstrated in the noisy
area of the 24 hour trend in Figure 1-2.If the MAX and MIN values are
within 2% of each other there is no need for the vertical line and only
the AVERAGE value pixel is darkened as in the quiet areas.
The top portion of each trend screen indicates channel #, real time
reading in engineering units, measurement name, range, and MIN,
MAX and AVERAGE values for the preceding 24 hour period.The SI
field on the top right indicates number of seconds remaining in the
current 6 minute subinterval.

1.1.2 Bar Graphs Screen
The HA71 Bar Graphs screen shown in Figure 1-3 allows all active
channels to be viewed simultaneously.Both engineering units values
and bar graph values are indicated
in real time. Lines across the bars
indicate the alarm trip points making
it easy to identify channels at or near
alarm.AfeatureintheSystemsmenu
tree allows new alarms to always
force the LCD to the bar graphs
screen.This is useful for applications
requiring channels with alarms to be
displayed.
1.1.3 Combination Screen
The HA71 Combination screen shown in Figure 1-4 offers a view of a
single channel but displays the data as a 10 minute trend, bar graph
and large engineering units. It is also useful for testing inputs for
stabilitysince MAX, MINand AVERAGEvaluesrefresh eachtime this
screen is selected. For example, to
teststabilityoveraonehourperiodfor
an input, begin timing as soon as the
channel is selected. One hour later
record the MAX, MIN and AVERAGE
values.The difference between MAX
and MIN indicates peak to peak
excursions over the one hour period
and AVERAGE is the average for the
hour. Longer or shorter tests may
also be run.The numeric value shown below the bar-graph indicates
number of minutes samples have been taken. After 999 minutes the
AVERAGE buffer overflows and the error message UPDATE appears
in the AVERAGE field.Exiting this screen resets the buffer and clears
the error message.

2.0 Basic Operation
The HA71 offers 3 graphic screens for viewing monitored data and
a Set-Up menu screen for operator interface to configuration menus.
They are shown below in Figure 2-1.The Bar Graphs screen allows
viewing of all active channels simultaneously. The Trend screen
displaysa24hour trend one channelatatime.TheCombinationscreen
displaysabargraph,large engineeringunitsanda10minutetrend one
channel at a time.Input channels may be displayed in sequence with
the UP/DOWN keys.The NEXT key switches between the 3 graphic
data screens.When HA71 power is applied, the graphic LCD returns
to the screen active when power was last removed.
Setup menus are entered by pressing EDIT from any data screen,
and scrolling to thedesired menu using the UP/DOWN keys.Pressing
EDIT again enters the selected menu’s tree of variables.This Setup
mode may be exited manually by pressing NEXT, or automatically
when no keys are pressed for 5 minutes. Alarm relays and front
panel alarm LED indicators remain active during the Setup mode.An
AUTHORIZE menu offers a password feature to prevent tampering
with HA71 parameters.

2.1 Setup Menu Configuration
Variables inside systemandchannel menu trees allowoptimumHA71
configuration for a wide range of demanding multi-point monitoring
applications. Access to menus is via the Setup mode by pressing
EDIT and activating the Setup screen shown in Figure 2-1. Menu
trees are provided for each of the 16 channels and another for system
variables. Select the desired menu by scrolling with UP/DOWN and
EDIT to enter the menus.
2.1.1 Changing MenuVariables Using the Keypad
Upon entering a menu, a pointer controlled by the UP/DOWN keys
indicates the selected variable.Some are simple YES/NO or ON/OFF
entriestoggledbypressingtheEDIT key.Others,suchasMeasurement
Name and Eunits fields may have many ASCII character possibilities.
Allowed ASCII characters are as follows:
ABCDEFGHIJKLMNOPQRSTUVWXYZ
abcdefghijklmnopqrstuvwxyz
BLANK SPACE
!”#$%&`()*+-./:;<=>?@
0123456789
EDIT places a cursor over the item and UP/DOWN scrolls through
each allowed entry.The NEXT key moves the cursor to the next
position within a field.When the field is complete, EDIT clears the
cursor and loads it into non-volatile memory where it is retained
indefinitely.With no cursor present, NEXT closes open menus in
reverse order and returns the LCD to the most recent data display.
