CONTROL INSTRUMENT FEATURES

8. FLOW CHART

This section outlines the most commonly used features of the Hawk 3 controller
and functions as a quick start guide. Please refer to the table of contents to find
in-depth information or advanced features.

Installation and Wiring

See Section 1 in this manual for specific wiring and installation information per­taining to user’s specific unit. With only the power supply wired, the Hawk 3 can
be programmed before installation. The Hawk 3 features non-volatile memory;
programming information will not be lost due to power loss or when changing
meter’s location.

Programming

Many of the advanced features of the Hawk 3 respond to, and interact with, each
other. When programming the Hawk 3 it is important that the proper order is fol­lowed when setting up features. The following is the recommended order.

1. Decimal Point

2. Linearization (AKA Scaling)

3. Set Point/Relay Control (if applicable)

4. Analog output or other applicable controls.

Basic Key Operation (for Programming)

1.  enters the main programming menu, backs out of submenus (one level at a
time) and returns to run mode from the main menu. Exiting the programming
menu in this manner assures that all changes will be saved.  also moves
the cursor to the left.

2.  scrolls through menus and changes parameters.

3. RES opens submenus, moves a blinking parameter into edit mode and allows
editing.

Decimal Point

Using the 3-1/2 digital Hawk 3 as an example, the decimal point can be placed
in any one of 5 locations without affecting the number. For example, 10 volts will
display as 10.00. This display can be changed to get 100.0. Keep in mind that the
decimal point is still needed for some applications.

1. Press  to enter the programming mode.

2. Scroll  until “dCtL” (display control) shows. Press nter .

3. When “DP” and “2345” flashes, press ter .

4. “2345” is now a fixed display. Use  or  to move the decimal point as neces­sary. Press Ente .

5. Use  to save changes.

Response Structure:

The Hawk 3 will not echo the command sent to it, but, will reply in one of three
ways:

1. “%” and some error message. The command was not understood or the
optional checksum failed.

2. “*” The command was accepted and the response requires no data.

3. “*{DATA}” The command was accepted and DATA is supplied in return.

The percent mark (% , ASCII 37, 25h) and the asterisk (* , ASCII 42, 2Ah) are
the only two valid response prefix characters.

Response Delay:

7. RS-485 COMMUNICATIONS

The RS-485 card is used for communication in a network where multiple sensors
(not necessarily Hawk 3 sensors) report back to a central host computer.
The RS-485 card is configured for 9600 baud, 8 bit, 1 stop bit, no parity, half duplex
serial communication, and will respond on a polled basis only. Each Hawk 3 will
respond to its own unique address only after being requested by the host. The
Hawk 3 remains a listener until asked to respond.

NOTE: User-friendly interface software for Microsoft Windows Operating Systems
is available to program and control the Hawk 3 remotely via the RS-485. Contact
Simpson Electric Company for details.

7.1 RS-485 Command Structure

[Prefix][Address][Command][Checksum][Carriage Return]

7.2 Prefix

The Hawk 3 listens for messages beginning with one of two prefix characters, the
dollar sign ($ , ASCII 36, 24h) or the pound sign (# , ASCII 35, 23h).
The dollar sign ($) requests a short response from the Hawk and the pound sign
(#) requests a long response with checksum from the Hawk.

7.3 Address

The next two characters represent the unit’s address. The characters can range
from “01” to “99”. All other characters in this position are ignored. This will match
the corresponding address on the Hawk 3 unit.

For example: With the address on the Hawk set at “01” the command to address
it would be “$01”.
The same scheme is used to derive the checksum on a long response, the carriage
return is again not calculated into the checksum.

Figure 2-1. Installation and Panel Cutout

2.1 Mounting Requirements

The Hawk 3 Advanced Digital Controller 1/8 DIN meters require a panel cutout
of 1.77” (45mm) high and 3.62” (92mm) wide. To install the meter into the panel
cutout, remove the clips from the side of the meter. Slide the meter through the
panel cutout, then slide the mounting clips back on the meter. Press evenly to
ensure a proper fit.

2.2 Engineering Label Placement

To replace the engineering unit label, place the tip of a ballpoint pen into the small
hole at the base of the engineering label in the bezel. Slide the label up until it
pops out. Grasp and remove. Slide the new label half the distance in, then use the
ballpoint pen to slide it into place.

2.3 Removing / Installing Modules

Shut power off before removing or installing modules.

1. Remove module from case by inserting a screwdriver into tab slot opening
on top of the module. Apply pressure to release module from case. Repeat
procedure for tab located on underside of the module and slide the module
away from the case.

2. To install a module, carefully align the module edges with the slots in the case
and press forward until the tabs (on top and bottom) engage.

NOTE: It is not recommended to replace input modules in the field; instrument
would require calibration.

The AC power cards operate from standard 50/60 Hz line power. The polarity for
connecting AC power (INⵑ) is unimportant. The unit operates either way. The DC to
DC power card is an isolated supply that operates between 9 and 36 volts DC.

The “Hold” feature is used to freeze the display. When the contacts are shorted, the
display will “Hold” the last reading until short is removed. It is recommended that
a mechanical switch or relay be used to activate the hold circuit; solid state relays
may give unexpected results. The hold circuit cannot be externally powered.

An external fuse is required for safe operation. For AC supply, use a Slow Blow
fuse at .25A, Littlefuse Part No. 313.250 or equal. For DC supply use a Slow Blow

Linearization will also affect the relation. The factory
default is when the input is at its lowest level the output
is 0VDC. When the input is at the maximum rated input
the output is at 10VDC.

The RS-485 card is used for communication in a network
where multiple sensors (not necessarily those of Hawk

3) report back to a central host computer.

* Factory Reset Default Values

The digital output is an RS-485 2 wire communication port. It has a fixed baud
rate of 9600 baud, half duplex and is addressable. When this card is installed, the
Hawk 3 senses the card and opens the menu choices available to the card. For
detailed command sets and communication configuration, please refer to RS-485
Communications, section 7 of this manual.

The analog output is a current or voltage that represents an equivalent range
of signal on the input. Analog output can be purchased as 4-20mADC out or
0-10V DC out. When installed, the Hawk 3 senses the card and opens the menu
choices available to the card.

6.7.1 Setting the Limits (LIM)

The ends of the analog output range (4 & 20 or 0 & 10) can be set or ‘pegged’
anywhere within the displayed value of the meter.

Example 1: The Hawk 3 is purchased as a standard 200 volt meter. The analog
output is configured by default , HI=100.0 and LO=0. When the display reaches
100 volts, the analog output will be 20mA. When the display reaches 0 volts the
analog output will be 4mA. In order to change the analog output to 20mA at 200
volts change the “HI” to 200.0

Example 2: The Hawk 3 is purchased as a process meter 4-20 mA input which
displays 0-100 percent. The analog output is configured, by default, for HI=100.0
and LO=0. When the display reaches 100 percent the analog output will be 20
mA. (Because the meter is a process meter, the input should be 20mA.) When the
display reaches 0 percent the analog output will be 4mA.

The limits can be moved or reversed (HI=0 and LO= 80.0). In this case when the
display reads “0”, the analog output will be 20mA and when the display reads “80”,
the analog output will be 4mA.

23

The RS-485 card is configured for 9600 baud, 8 bit, 1
stop bit, no parity, half duplex serial communication,
and will respond on a polled basis only. Each Hawk 3
will respond to it’s own unique address only after being
requested by the host. The Hawk 3 remains a listener
until asked to respond. (See section 7 of this manual for

Tare (Zero or Null): using tare allows user to grab a running offset and zero to it.
A running offset can monitor the tolerance of a value instead of the value itself, or
remove some signal offset in a measurement. Once tare in enabled in the menu
(Tare = ON), the device will wait until  and  is pressed. The unit will then grab
the current value and offset the display to zero. Choose “hold” in the tare menu to
save the tare value to a more permanent location. No new tare can be taken, but
the value will be saved if power fails.

NOTE: Be aware that introducing a tare value will change the setpoint thresholds
and erase any previous Hi Lo readings.

1. Press  to enter the programming mode.

2. Scroll  until “MEAS” (Measure control) shows. Press REs .

3. When “tArE” and “on” flashes, press REs .

The following parameter order is recommended to change the display from the
default values. Parameters entered in any other order may cause unexpected
results.

DP (decimal point position): the decimal point location can serve as the magni-
fication of a value. For Example: To display 0-200 or 2000 on a 0-20 volt meter
move the decimal point to represent that scale. The display comes without decimal
point enabled, Electrical Full Scale will be 20,000 counts on the display (With the
exception of 5 Amps).

The decimal point should be set before setting linearization.

1. Press  to enter the programming mode.

2. Scroll  until “dCtL” (display control) shows. Press REs .

3. When “DP” and “12345” flashes, press REs .

4. “12345” is now a fixed display. Use  or  to move the decimal point as

necessary. Press REs .

5. Exit the programming menu by pressing  until “UPDT FLSH” flashes. Exit the

programming menu properly to make sure system changes will be saved. If
“UPDT FLSH” does not display, changes must be re-entered and saved.

Display refresh; “FrSH”, will show the numbers of updates made. This setting ranges
from 480 updates per minute (8 updates per second) to 1 update per minute.

1. When “FrSH” and “240” flashes, press REs .

2. “00240” is now displayed. Use ,  or  to change the refresh rate.
Press REs .

The display banding, “bAnd” works differently. The value entered is the amount
of digit movement allowed before the display is updated. With a band setting of
2, the value must move 2 counts up or down in the rightmost position to update
the display.

1. When “bAnd” and “0” flashes, press REs .

2. “00000” is now displayed. Use ,  or  to change the band. Press REs .

NOTE: “FrSH” and “bAnd” can adjust the display response and remove “pops” and
“jitters”. The actual raw signal is evaluated against the setpoint and will go into alarm
even if the display was set for maximum filtering and gave no indication of nearing
the setpoint. Use hysteresis or delay in SP menu to slow relay action.

Value - 1 to 480 updates per minute (240*)

Value - 0* to 99 counts from current value.

 and  arrows move LED brightness
through 5 levels as indicated on display.
(5* full brightness)

DP - Always change the decimal point location first, to the desired display range. The
decimal point will then be in the proper position for setting setpoints or linearization.
Magnifying the display from 10 to 100 is as simple as moving the decimal point.

LIN - Linearization affects the setpoints and analog-out results. If decimal point
location is changed, it will display in the wrong place for electrical input, but in the
desired location for output display.

SP 1 – 4 - The setpoints follow the displayed results of any linearization or decimal
point settings and not necessarily the electrical input.

A OUT - The analog-out “Hi and Lo” settings also track the display results from the
above changes and not the electrical input.

6.2 General Programming Guidelines

Changes can be made while programming, unless the outputs or relay alarms are
critical to operation.

1. Press  to move in and out of the main programming.

2. Press or  to scroll to desired submenu. Press REs to enter a submenu.
Press  to scroll back to main menu.

3. To change a flashing parameter press REs and press ,or . To save

change and proceed to the next change, press .

the

NOTE: ALWAYS SAVE CHANGES! Improperly saved changes will be lost if
power fails.

4. Press REs after making the last change, then return to run mode by pressing
 while in main menu mode. “Updt FLSH” will display before displaying run
mode.

6.3 Programming Menu

Available menu choices depend on the operator’s password rights. Use caution
when changing values “on the fly” because relay changes are immediate upon
exiting menus. While in local menu, RS-485 communications will halt to avoid
command conflict. When in local or remote menu, relay and alarm operations are
suspended. If left in menu mode the local or remote menu will “time out” in two
minutes then resume normal operation.
