Basic Operating Instructions
Rate, Time, and Counter Modes Explained
In Rate Mode, the DTM8000 measures the input frequency, converts it to the user-defined units, and
displays the rate in the display window of the user interfaceꢀ Most applications utilize rate mode and
display in units such as gallons-per-minute, feet-per-second, and RPMꢀ
In Time Mode, the DMT8000 measures the input frequency, converts it to the user-defined time units,
and displays the time in the display windowꢀ This mode is most-commonly used in time-sensitive
processes such as conveyor ovens and plating applicationsꢀ
In Counter Modes, the DTM8000 counts each incoming pulse, scales it per the user-defined ratios, and
displays the count in the display windowꢀ Typical counting applications include linear material
measurement, cycle counters, and liquid volume measurementꢀ

How to Change a Parameter's Value (The Short Story)
1ꢀ Hold down the Enter button until Parameter-Selection Mode is entered
2ꢀ Using the Up and Down buttons, select the desired parameter number to view or edit
3ꢀ Press the Enter button to change the value of the parameter
4ꢀ Using the Up and Down buttons, change the parameter's value as desired
5ꢀ Press the Enter button to permanently save the changes (Return to Parameter-Selection Mode)
6ꢀ Select parameter zero and press the Enter button to return to Running Mode
Operating the User Interface (The Long Story)
The LED display has three basic operating modes: Running Mode, Parameter-Selection Mode, and
Value Modeꢀ Each of the three modes have specific visual indicators that allow the user to immediately
determine the current state or mode of the user interfaceꢀ Parameter-Selection Mode and Value
Mode can only be entered if the Program Enable jumper is in the “On” positionꢀ
Download from Www.Somanuals.6com. All Manuals Search And Download.
Running Mode is the default display of the unit when power is appliedꢀ In Running Mode, the display
shows the measured value in the appropriate user-defined format of rate, time, or countꢀ As the input
signal changes, the display is continuously updated to show the latest measurementꢀ In this display
mode, the Up and Down buttons serve no function other that to reset or silence alarms if configured
accordinglyꢀ Example displays for rate, time, and count operating modes are 13ꢀ60, 45:30, and 9301ꢀ
Parameter-Selection Mode can be entered by simply pressing and holding the Enter button down for
three secondsꢀ Once in Parameter-Selection Mode, the far left of the display will be a ‘P’ꢀ The right side
of the display will indicate the currently selected parameter number for editing purposesꢀ Pressing the
Up or Down button will increase or decrease the selected parameter number on the displayꢀ Although
the parameter numbers are in numerical order, some numbers are skippedꢀ These numbers represent
reserved parameters that are not displayedꢀ Once the desired parameter number is displayed, a press
of the Enter button will change the display to the Value Modeꢀ When in Parameter-Selection Mode,
pressing the Enter button with parameter 0 selected will cause the unit to return to Running
Modeꢀ Example displays for Parameter-Selection Mode are P 1, P 11, and P 54ꢀ
Value Mode is used to modify the value of the selected parameterꢀ When in Value Mode, the two dots
which form the colon, between digits two and three, will alternately flash (one, then the other) to inform
the user that a parameter’s value is being editedꢀ Pressing the Up or Down button increases or
decreasestheselectedparameter’svalueꢀ Valuechangestakeeffectimmediatelyꢀ Forexample,when
scrolling through the alarm output conditions, the relay will activate as the always-active selection is
passedꢀ Once the desired value is showing in the display window, pressing the Enter button again will
return to Parameter-Selection Modeꢀ The new value is not saved in permanent memory until the Enter
button is pressedꢀ Removing power from the unit while in Value Mode may result in the specified new
value being lostꢀ
Detailed Configuration Instructions
Factory Set Configuration
When shipped from the factory, the following basic settings are in place:
Rate Mode Operation in RPM
S1 Signal Input Pulses-per-Revolution: 10
Decimal Point Display: Off
Auto-Ranging: Disabled
Alarm Output(s): Disabled
Resetting the Unit to Factory Settings
The factory settings can be easily restored using either of two methodsꢀ Both methods require the
Program Enable jumper to be in the “On” positionꢀ The first is to apply power to the unit with both the
Enter and Down buttons pressed for 3 secondsꢀ The second is to change the value of parameter 95
to 5ꢀ
JP1 (Program Enable Jumper)
The JP1 jumper is located under the dust cover on the back end of the upper boardꢀ When the jumper
is set to the "Off" position, all programming features are locked out to the front panel userꢀ When the
jumper is in the "On" position, the programming parameters are open to changeꢀ JP1 is shipped from
the factory set in the "On" positionꢀ

Parameter Descriptions
Parameter 0 – Exit to Running Mode
Whenparameter0isselectedinParameter-SelectionMode,theunitwillreturntoRunningMode
and display the running valueꢀ This should be selected once changes to parameters are
completedꢀ
Parameter 1 – Model Number (Read Only)
This is a number which represents the base model number for the productꢀ For the DTM8000,
the model code is 80ꢀ
Parameter 2 – Software Build (Read Only)
The software build is a code which identifies the software version of the unitꢀ
Parameter 3 – Hardware Version (Read Only)
The hardware version is a code which identifies which hardware was used to build the unitꢀ
Parameter 4 & 5 – Serial Number, Major & Minor (Read Only)
These parameters are reserved for future use as an electronic serial number and are unique to
each manufactured unitꢀ
Parameter 10 – Operating Mode
This parameter defines the basic mode of operation for the entire unitꢀ It determines if the unit
is measuring rate, time, or count informationꢀ The following modes are available:
Mode 1 – Rate Mode
Rate mode displays measurements in rate units such as RPM, Gallons per Hour, or Feet
per Secondꢀ
Mode 2 – Time Mode
Time mode displays measurements in time units using the format AA:BBꢀ By default
AA:BB represents minutes (AA) and seconds (BB)ꢀ Optionally, it can be configured to
represent hours(AA)andminutes(BB)orotheruser-definedunitswitha1:60relationshipꢀ
Mode 3 – Up Counter
Counter modes (3 – 5), display measurements in pulse counts or user-defined units which
are proportional to pulse countꢀ In these modes, the DTM8000 will count the pulses which
are applied to the S1 input and display the related valueꢀ In this mode, each input pulse
increments the counterꢀ
Mode 4 – Down Counter
Same as Mode 3 above except each input pulse decrements the counterꢀ
Mode 5 – Up / Down Counter
Same as Mode 3 above except each input pulse either increments or decrements the
counter depending upon the state of Signal Input #2 (S2)ꢀ If S2 is tied to common, the
counter is incremented; otherwise, it is decrementedꢀ
Parameter 11 – Display Intensity
This parameter adjusts the intensity of the LED display digits in the front panel of the unitꢀ The
values of 0 – 31 correspond to a gradual change from very dim to very brightꢀ This is often useful
when used in the same panel as other pieces of equipment with LED displays and a uniform
display brightness is desiredꢀ
Parameter 14 – Input Triggers / Prescale
This parameter determines how the S1 signal input is processedꢀ It specifies which signal edge
is used for the measurements and the value of the internal frequency divider or prescalerꢀ
Modes 3 and 4 should only be used if the input pulse rate exceeds the unit's maximum native
pulse rate (see specifications for details); otherwise, timing and counting calculations may
become sluggish and unnecessarily inaccurateꢀ
Mode 1: Every Rising Edge, No Prescaler
In this mode, the signal input is measured at every rising edgeꢀ
Mode 2: Every Falling Edge, No Prescaler
In this mode, the signal input is measured at every falling edgeꢀ
10
Mode 3: Falling Edge, Prescaler = 4
Inthismode,thesignalinputismeasuredatevery4thfallingedgeꢀ Thismodeisespecially
useful when the signal input frequency is beyond the native pulse-per-minute range of the
DTM8000ꢀ Because unit will automatically compensates for the prescaler, there is no
need to factor in the prescaler value when setting the Display and RPM Reference
parametersꢀ
Mode 4: Falling Edge, Prescaler = 16
Same as Mode 3 except the signal input is only measures every 16th falling edgeꢀ
Parameter 16 – Counter Reset Configuration
In counter applications, it is often desirable to have the user or an external signal reset the
counter value to zero or some predetermined valueꢀ This parameter specifies which actions
will cause the counter to reset to the Counter Reset / Preset Value, parameter 27ꢀ
Mode 1: Reset Disabled
The counter cannot be resetꢀ
Mode 2: Reset On Button Press
The counter will reset to the Counter Reset / Preset Value, parameter 27, when any of the
user-interface buttons are depressedꢀ
Mode 3: Reset On S2 Input Low (Wired To Common)
The counter will reset to the Counter Reset / Preset Value, parameter 27, when S2 (signal
2) is brought to an electrically low state or wired to the unit's commonꢀ
Mode 4: Reset On S2 Input High (Not Wired To Common)
The counter will reset to the Counter Reset / Preset Value, parameter 27, when S2 (signal
2) is brought to an electrically high state (+5V) or left to float disconnected from the unit's
commonꢀ
Parameter 20 – Signal Input 1 (S1) Display Reference
This is the number to be displayed when at the user-specified motor Reference RPMꢀ In Rate
Mode, this value represents the numerator of the rate unit such as feet, ounces, or revolutionsꢀ
In Time Mode, this value represents the reference time measured in seconds or minutesꢀ If the
desireddisplayisHH:MM,thenallvaluesshouldbeenteredinminutesꢀ IfMM:SSisdesired,then
all values should be entered in secondsꢀ In Counter Modes, this value is the reference count
ratio which corresponds to the number of counts which equate to the specified number of
reference pulses, parameter 21ꢀ See applications for examplesꢀ
Parameter 21 – Signal Input 1 (S1) Reference RPM (Reference Pulses in Counter Modes)
This is the reference RPM at which the Display Reference value should be displayedꢀ In Rate
and Time Modes, this value represents the RPM of the encoder to which the Display Reference
correspondsꢀ In Counter Modes, this value is the Reference Pulses which correspond the the
specified number of displayed counter, parameter 21ꢀ See applications for examplesꢀ
Parameter 22 – Signal Input 1 (S1) Pulses per Revolution
This is the number of pulses per revolutionꢀ Value may be from 1 to 9999ꢀ
Parameter 23 – Signal Input 1 (S1) Recovery Rate
This is the rate at which the display will attempt to recover once the pulse train appears to have
stoppedꢀ The recovery rate is the number of half seconds which the unit will wait before dividing
(Rate Mode) or multiplying (Time Mode) the display value by 2 in an attempt to accurately
represent the current speed or timeꢀ In the absence of input pulses, this will continue at regular
intervals until either 0 (Rate Mode) or 99:99 (Time Mode) is reachedꢀ Setting this parameter to
0 will disable the automatic recovery featureꢀ If this parameter is set too low for the application,
thedivisionormultiplicationmayprematurelyoccurcausingthereadingtoreadtoohigh,toolow,
or unstableꢀ This can easily be corrected by simply increasing this parameter's value or
disabling it by setting it to zeroꢀ
Parameter 24 – Signal Input 1 (S1) Display Smoothing / Averaging
This is the amount of time, in 1-second increments, which will be averaged before updating the
displayꢀ Setting this parameter to 0 will disable the averaging featureꢀ
11
Parameter 25 – Signal Input 1 (S1) Decimal Point (DP) Position
Thisselectstheformatofthedisplaywithrespecttothedecimalpoint’spositionꢀ Thisparameter
does not effect the value entry for other parametersꢀ For example, it the user desires to display
10ꢀ00 at an input of 300RPM, then parameter 20 would be set to 1000, parameter 21 would be
set to 300, and parameter 25 would be set to 2ꢀ
Mode 0: Fixed XXXX
Mode 1: Fixed XꢀXXX
Mode 2: Fixed XXꢀXX
Mode 3: Fixed XXXꢀX
Mode 4: Fixed XXXXꢀ
Parameter 26 – Signal Input 1 (S1) Auto-Ranging Configuration
This selects how the unit auto-ranges and formats the numbers for the displayꢀ
Mode 0: Auto-Ranging Disabled
The auto-ranging mode is disabledꢀ Ignoring decimal points, this limits the units display
range from 0 to 9999ꢀ Values beyond this range will display as an overflow error (-OF-)ꢀ
Mode 1: Auto-Ranging On Overflow Only
In this mode, auto-ranging will only be activated if the display value exceeds the maximum
native display valueꢀ For example, in XXꢀXX decimal point mode, 99ꢀ99 would be the
maximum native value for a 4-digit displayꢀ When the display is in overflow, it will display
only the 4 most significant digits and the decimal point will flashꢀ
Mode 2: Auto-Ranging Always Active
Inthismode,auto-rangingisalwaysactiveandcontinuouslyattemptstodisplaythe4most
significant digitsꢀ For example, the display will automatically range from 0ꢀ001 to 9999 as
neededꢀ In this mode, any value over 9999 will be displayed as an overflow error (-OF-)ꢀ
Parameter 27 – Counter Reset / Preset Value
Thisisthevaluethatwillautomaticallybeloadedintothedisplayafterthecounterhasbeenresetꢀ
See Counter Reset Configuration, parameter 16, for more detailsꢀ
Parameter 30, 31, 32, 33, 34, 35, and 36
Reserved For Future Useꢀ
Parameter 37 – Signal Input 2 (S2) Counter Gate (Enable / Disable) Configuration
This selects how the S2 input is utilized in single channel counter modesꢀ
Mode 1: Disabled (Required For Up / Down Counter Mode)
The S2 input will not function as a gate control and instead will act as the second input for
dual-channel counter operationꢀ
Mode 2: Counting Enabled When S2 Input Low (Wired To Common)
The unit will continue to count input pulses as long as the S2 is in an electrically low state
or connected to the unit's common terminalꢀ When the S2 input goes high (+5V) or is
allowed to float disconnected, the counter will be frozen at its current valueꢀ
Mode 3: Counting Enabled When S2 Input High (Not Wired To Common)
The unit will continue to count input pulses as long as the S2 is in an electrically high (+5V)
state or allowed to float disconnectedꢀ When the S2 input goes low or is wired to the unit's
common, the counter will be frozen at its current valueꢀ
Parameter 40 & 50 – Alarm 1 & 2 Conditions
This defines which conditions will result in the alarm 1 or alarm 2 outputs being activatedꢀ
Mode 0: Always Inactive
The alarm output will remain in an inactive stateꢀ In this state, the NC and C contacts will
be internally electrically connectedꢀ

Because the initial values were 40 revolutions per 3.5 inches of platform motion, each is
multiplied by 10 to give an even number to increase accuracy since the display can be
programmed in whole numbers. Additionally, because of the decimal point position, the
Display Reference is multiplied by 10 to generate the proper display format. Without the
second multiplication by 10, the display would only read 3.5 inches when the drive motor
turned 400 revolutions.

In count mode, the Reference RPM is set in revolutions. 400 has been entered here to
represent 40 revolutions and the Display Reference has also been multiplied by 10 to yield
whole numbers.

Troubleshooting
Problem
Possible Case
Solution
Display is blank
Power not applied
Using a volt meter, verify that a voltage between 85 and 265VAC is measured between
the L and N terminal block positions.
Contact technical support for additional help and instructions.
Defective unit
Display is dim
Display intensity
parameter is too low
Editing and increasing the display intensity parameter should cause the display digits to
become brighter.
When power is
applied, “LF-L” is

AC line supplying
power to unit has too
much noise
Review routing of power wires in machine to minimize electrical noise. Look for other
devices which share the same circuit which may be producing unacceptable levels of line
noise. In some applications, such as welding equipment, a careful regiment of applying
an AC line filter, re-routine wires, dividing circuits, using shielded cable, and properly
grounding devices will usually solve the problem.

power to unit has an
abnormally low
frequency
The unit is designed to operate with AC lines from 48-62 Hertz (cycles per second).

Second alarm output parameters not configured properly
Review alarm output #2 parameters. The first and second alarm relay outputs can be
tested by selecting the “Always On” value for the Activation Condition parameters for the
respective alarm output. When doing this, the relay click should be audible and the NC
(Normally Closed) and C (Common) terminals should become internally shorted at the
terminal block.
