The relay cards are directly related to any alarms that occur on the Hawk 3.
The single relay is a “Form C” relay that activates in relationship to “SP1”.
The dual relay is a Form C” relay that activates in relationship to “SP1” & “SP2”.
The quad relay is a “Form A” relay that activates in relationship to “SP1” through “SP4”.

NOTE: “SP3” and “SP4” connections share a common.

All relay contacts are rated at 250VAC @ 5 amp maximum. The rating of the relay contact is intended for
resistive circuits only. Use a snubber circuit to protect the contacts from inductive loads.

Tous les contacts de relais sont évalués à 250VAC @ 5 ampères maximum. La note du contact de relais
est destiné uniquement aux circuits résistifs. Utiliser un circuit de protection pour protéger les contacts à
partir de charges inductives.

7.2 Frequently Asked Questions

What is a Form A or Form C relay?

The form A relay is a 1 contact switch that is either closed or open. The form C relay has 2 contacts, one of which
will be closed and one open. With the fac tory defaults used, N.O. on the relay means normally open when the
Hawk 3 is not in alarm. N.C. means normally closed when the Hawk 3 is not in alarm.

What does N.D. and N.E. do to the relay?

The effect of the relay can be reversed by setting the relay action to N.E. (nor mally energized) in the menu. When
the Hawk 3 is not in alarm, the N.C. contact will now be open and the N.O. contact will be closed. Setting the
alarm response back to N.D. (normally de-energized) will put the contacts back to their default state.

The hold feature is used to freeze the display. When the contacts are shorted, the
display will “Hold” the last reading until the short is removed. It is recom mended 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 ex ternally powered.

La fonction de maintien est utilisé pour geler l’afchage. Lorsque les contacts sont
court-circuitées, l’afchage “Hold” la dernière lecture jusqu’à ce que le court-circuit
est éliminé. Il est recommandé qu’un commutateur ou relais mécanique être utilisés
pour activer le circuit de maintien, relais statiques peuvent donner des résultats
inattendus. Le circuit de blocage ne peut pas être effectuée en externe.

9. MENU DETAIL

9.1 Relay Control (Sp1-Sp4)

While in menu, all other operations are suspended.

The H340 has four setpoint parameters and up to four relays associated with
those four setpoints. The setpoint LEDs on the display will light even if no relay
is present for that setpoint.

To change the setpoint value, enter the menu by pressing W. If the password
allows relay control, it will be the first menu to appear. The display will show the
word “Sp1”. If this is the setpoint to be edited, press RE , otherwise press T
to move to the next choice. When editing Sp1, the display will alternate be­tween Val-1 and a value. The “value” represents a threshold above or below
the setpoint being set to alarm.

NOTE: Before editing this value, be sure that the decimal point is in the proper
position. It is also recommended that any scaling or linearization be entered
before setpoints are determined.

Press RE to choose Val-1 as the setting to be edited. Notice that the far right

RESET
ENTER

digit has an alternating cursor. To change this digit, use S or T. To move to the
next digit, press W. When all changes to the value are complete, press

RESET

RE to confirm the change and save it to memory.

ENTER

NOTE: Any power loss before confirming a change will lose the edited value.
The menu will revert back to alternating between Val-1 and value. Press T to
move to the response setting.

RESET
ENTER

9.1.1 Response

The display will now show “Rsp.” To edit response, press RE , otherwise

RESET
ENTER

press T to move to the next choice. When editing Rsp., the display will show
Hyst, Dlay, or Ltch Flashing. Use S or T to choose the required response.
Press RE to confirm the choice. When choosing Hyst, the display will

RESET
ENTER

alternate between Hyst and the current value.

To edit the value, press RE . Otherwise press T to move to the next choice.

RESET
ENTER

Hysteresis will be used above and below the setpoint in equal amounts. The
value represents a percentage of the setpoint. For example: If the setpoint is
set to 100.00 with a high alarm and therhysteresis is set for 8.5%, the alarm
will not turn on until the reading on the display reaches 108.50. Once tripped,
the alarm will not turn off until the display reaches 91.50.

9.1.2 Delay

When choosing Dlay, the display will alternate between Dlay and current value.
To edit the value press RE . Otherwise press q to move to the next choice.
Dlay will be used above and below the setpoint in equal amounts. The value
represents the amount of delay in seconds. For example, if the setpoint is
again configured for high alarm and Dlay is set for 2.5 seconds the display
crosses the setpoint value and a timer begins to count off the 2.5 seconds
before the alarm trips. If, during those 2.5 seconds the value falls below the
setpoint, no action will be taken. When the unit successfully counts off 2.5

RESET
ENTER

17

seconds the alarm will trip and remain in alarm until the display drops below
the setpoint for at least 2.5 seconds

9.1.3 Latch

When choosing Ltch, the relay output will latch immediately after crossing the
setpoint. The unit can then only be unlatched with a front panel reset or a reset
command from the RS-485 port.

NOTE: If the display is still beyond the setpoint threshold, the reset will have
no effect and the unit will remain latched.

9.1.4 Alarm

The Alr mode allows choice between High, Low, or Off. The High Alarm means
that the display value must be greater or equal to the setpoint to go into Alarm.
The Low Alarm means that the display value must be less than or equal to the
setpoint to into alarm The Off Alarm means that all features of this setpoint is
disabled. No action will occur when display crosses a setpoint and the relays
will revert to a normally de-energized state.

When selecting St (State) from the menu, the display will alternate between
Stand the current setting.

To edit the setting press RE . Otherwise press T to m

RESET
ENTER

If choosing ND (Normally De-energized) the relay will turn “on” the alar
dition. This is a typical configuration. The one and two-relay outputs will act as
abeled; the normally closed contact will be closed until an alarm condition
occurs, and the opposite is true for the normally open connection. The four­relay output only has the choice of normally open.

If choosing NE (Normally Energized) the relay will turn on at power up and
remain on until in an alarm condition. This mode can be used to create a fail­safe condition or reverse the action of the four-relay configuration. In the fail­safe example, the relay output would be wired to protect some device during
an alarm condition. During a power failure, the relay would be in the same
position as though it were in alarm thus protecting a device that may be on a
separate and possible active circuit.

9.2 Display Control

The next item that will appear in the menu is Dctl (Display Control). If this is
the item to be edited press
to the next choice.

The display degrees, Deg, will allow you to select either °F or °C for the tem­perature indication. There is no need to change this value if you prefer the
default °C indication.

The display refresh, frsh, will slow the numbers of updates to the display. This
setting ranges from as fast as 480 updates per minute (8 updates per second)
to as slow as 1 update per minute.

The display banding, band, works from a different approach. The value en­tered is the amount of digit movement allowed before the display should be
updated. With a band setting of 2, the value must move 2 counts up or down in
the rightmost position as compared to the current display to cause the display
to update.

NOTE: The two previous features can finely or coarsely stabilize the display
and remove the pops and jitters typically found when monitoring a power line.
The adjustment of this setting only filters what is displayed. The actual raw
signal is evaluated against the setpoint and will go into alarm even if the
display were set for maximum filtering and gave no indication of nearing the
setpoint. Use hysteresis on delay in SP menu to slow relay action.

The Brit( Brightness) of the display is adjustable to allow for dimming in low
light applications or for intensity matching with other equipment. The default is
set to the brightest setting (5).

ICE (Zero or Null) Using ICE allows the user to grab a running offset and zero
to it. A running offset can be useful for monitoring the tolerance to a value
instead of the value, cancelling lead error in measurement or removing some
signal difference in a measurement. Once ICE in enabled in the menu (ICE =
ON), the device will wait until the user presses S and T . At that point, the unit
will grab the current value and offset the display to zero. By choosing “hold” in
the ICE menu the ICE value can then be saved to a more permanent location.
No new ICE can be be taken, but the value will noy be lost if power fails.

NOTE: Be aware that introducing a ICE value will change the setpoint thresh­olds and erase any previous Hi Lo readings.
HILO (Min/Max) allows the user track the history of the readings on the dis­play. By pressing S, the unit will momentarily display the highest value it has
reached after last being reset. By pressing T, the unit will momentarily display
the lowest value it has reached after last being reset.

9.3 Output Control

An optional analog outputs is available.

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

Setting the limits (LIM). The ends of the analog output range (4 & 20 or 0 & 10)
can be set or ‘pegged’ to and display value within the range of the meter.

Example: The Hawk 3 is purchased as a standard 200 volt meter. The analog
output is configured, by default, for HI=100.0 and LO=0.
When the display reaches 100 volts, the analog output would be 20mA. When
the display reaches 0 volts the analog output would be 4mA.
The Hawk3 is purchased as a process meter 4 – 20 mA input which will dis­play 0-100 percent. The analog output is configured, by default, for HI=100.0
and LO=0. This means when the display reached 100 percent the analog out­put would be 20 mA. (Also, because this is a process meter the input should be

19

20mA) When the display reaches 0 percent the analog output would 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 would be 20mA and when the display
reads 80, the analog output would be 4mA.

The Fail Safe option (FS) controls the action of the analog output when the
display goes into over-range (EEEE or –EEE).

In some cases, the low limit or high limit are reserved for error conditions.
With set to ‘HI’, the output will run to the 20mA value when over-range or
under-range occur. With failsafe set to ‘LO’, the output will run to 4mA at
over-range or under-range.

With failsafe ‘Off’, the output will go to the dened limit ends. (-EEE would be

4mA and
EEEE would be 20mA typically.)
