P1-3 (2NO) This is the normally-open contact of the second user assignable relay output.
P1-4 (1NC) This is the normally-closed contact of the first user assignable relay output.
P1-5 (1C) This is the common contact of the first user assignable relay.
P1-6 (1NO) This is the normally-open contact of the first user assignable relay output.
P1-7 (AC / N) For single phase AC lines connect the Neutral side of your AC line to this terminal. For
systems with two hot AC lines, connect either of the Hot AC lines to this terminal.
P1-8 (AC / L) For single phase AC lines connect the Hot side of your AC line to this terminal. For
systems with two hot AC lines, connect either of the Hot AC lines to this terminal.
P1-9 (COM) This is the common point for the control logic. The speed sensor common lead as well
as any other source needing to reference the control common will be connected to this terminal.
P1-10 (+5V) This is a self-contained +5VDC power supply capable of up to 50mA. The speed sensor
supply lead can be connected to this terminal for its power source.
P1-11 (S1) This is the Signal input terminal for single channel operation or channel 1 of dual channel
operation. The signal lead of your speed or counter sensor will be connected here.
P1-12 (S2) This is the Signal input terminal for channel 2 during dual channel operation. The second
signal lead of the speed or position sensor should be connected here. This terminal is also used
as a reset input or function change input for various operations of the control. In counter modes,
this input may also be used as a counter reset or enable gate.

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

How to Change a Parameter's Value (The Short Story)
1. Hold down the Enter button until Parameter-Selection Mode is entered
2. Using the Up and Down buttons, select the desired parameter number to view or edit
3. Press the Enter button to change the value of the parameter
4. Using the Up and Down buttons, change the parameter's value as desired
5. Press the Enter button to permanently save the changes (Return to Parameter-Selection Mode)
6. 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 Mode. Each of the three modes have specific visual indicators that allow the user to immediately
determine the current state or mode of the user interface. Parameter-Selection Mode and Value
Mode can only be entered if the Program Enable jumper is in the On position.
