Panel Mount Tachometer

Model DT-5TG (VDC)

Features

Operational Precautions

If the unit is used in a caustic environment, we

suggest you use a NEMA 4X enclosure.

Keep unit free of vibration and shock.

When installing unit, keep power and sensor wires

separate. Tie cable shield to terminal E (earth ground).

After inserting wires, tighten terminal screws securely.

One of the most advanced on the market today, this

microprocessor-based panel tachometer not only mea-

sures rotational, linear and flow rate speeds, but can also

function as an elapsed time counter and ratio meter. By

choosing the desired input/output module(s), you can

design virtually any system imaginable.

Mounts easily — no brackets or screws or any other

hardware needed.

Tolerates a wide variation of voltages.

Immune to electrically noisy environments.

Programmable parameters and functions via front

panel membrane push-button switches.

Accepts a variety of input and output modules

No need to remember mathematical formulas.

Highly accurate.

Self-testing.

Connections Mode Selections 1&2 DC input terminals. 3 Earth ground. Connect all cable shielding to this terminal. 4 12 VDC 50mA max. This sensor power supply is for any sensor that requires external power 5 Switch closure input. To be used with a relay or solenoid. The input frequency must be less than 20Hz. 6 For use with open collector sensors. Connect the sensor's signal output wire. No need for an external pull-up resistor. 7 Terminal to accept signals from rotary encoders or pulse generators.

Setting Modes Setting Parameters 1.Apply any voltage between 9–35 VDC to terminals 1 and 2. When power is applied, the display will show all zeroes. After half a second, the display will change to 0. 2.Press mode and data set keys for at least 5 seconds. A zero will flash until 1 appears on the display. 3.Press the increment key to select the mode you want. Mode sequence will depend on input module 4.Press mode key. You're now ready to program the parameters for the mode you have selected.

Setting Parameters (cont'd) Parameter 3: Display Units Program this parameter to the desired display value corresponding to the parameter 2 setting. For example, suppose a conveyor is running at 157 fpm and 1,000 rpm sensing speed. This parameter would then be programmed for 157. 1. Press mode key. 2. Press increment and shift keys to change display. Parameter 7: Acceleration This parameter is useful when rate speeds accelerate or stop rapidly.

Mode 2: Elapsed Time Mode This mode monitors the time of a continuously variable process. Say, for example, a baker wants to know the amount of time needed to bake cookies. By using a stopwatch, he could measure the amount of time it takes at a known speed of the conveyor. Or, the baker could calculate this time by using the distance formula d=vt. By knowing the calculation time (parameter 4) and rpm of the sensing gear (parameter 2), the baker can continuously monitor the time as the process varies.

Mode 5: Self Test Display Switches & Functions This mode lets you check the LED display and input circuitry. The DT-5TG has seven display functions located above the display. All functions have an LED indicator and all but GO have a membrane switch. Here is a brief description of each function: 1.Press mode and data set keys for five seconds. HI If the display is equal to or greater than the HI limit setting, the LED will light and a contact will close.

Available Modules The DT-5TG is available with one, two, or three module connectors. Each type is indicated by its suffix: Optional modules are available from Shimpo. Choose any of the following modules – no internal hardware modification is required. DT-5TG-0 No connector DT-5TG-1 1 connector DT-5TG-2 2 connectors Module connectors: DOP-1A DOP-2A For single module For dual module Multiple Modules: In most applications, two modules may be interfaced with the DT-5TG-2.
