Overview
The purpose of this manual is to provide the users with the information necessary to
install and operate the DST-2000C™ Direction Sensing Tachometer.
1 Product Description
The DST-2000C operates with the M343 dual output magnetic pickup to detect the
direction of rotation, and provides outputs to indicate direction and speed. (The older
M917 pickup is no longer manufactured. This pickup ONLY works with the DST-2000B.)
Features
• Provides two SPDT relay outputs, one energizes on CW rotation, the other on
CCW rotation.
• Provides two 10 mA drive current outputs to illuminate customer-provided LED
indicators, one for CW rotation, the other for CCW rotation.
• Provides two pulsed outputs, one for CW rotation, the other for CCW rotation,
that can serve as an input signal to Dynalco tachometer DS-800.
• Provides a 0–1 mA output proportional to speed that can serve as input signal to
Dynalco tachometer models G-101 or DPM-105.
• Provides an amplified square wave output signal equal to the input frequency to
serve as input signal for Dynalco models SPD-100, SPD-700, LST-100, and
DS-800.
• Provides a regulated 8 Vdc (25 mA) auxiliary output to power Dynalco digital
panel meter DPM-105.


 Functional Description
The DST-2000C receives two input signals from the Dynalco M343 dual output
magnetic pickup. The circuits within the DST-2000C evaluate the two input signals
and activate the appropriate relay (CW or CCW) to indicate direction of rotation.
The DST-2000C outputs a proportional 0–1 mA analog signal as well as a buffered
square wave (8 V peak-to-peak) equal to the input frequency. The DST-2000C also
outputs a 10 mA signal to drive external LEDs which indicate the direction of rotation
(CW and CCW). There are also two pulse outputs, one for CW, the other for CCW.
There is one pulse per discontinuity. Pulses are 0 to +8 Vdc, 35 microsecond
nominal width.
To avoid false indications at near zero speed, the active relay indicating direction will
remain activated for 2 seconds with no signal input. It will then automatically reset.

 Minimum Speed Requirements
At very low speeds, the amplitude of the output signal from the M343 will be below
the sensitivity level of the DST-2000C. At these low speeds the DST-2000C will not
be able to detect direction of rotation. The output amplitude of the M343 is affected
by the diameter of the gear being sensed and by the air gap between the gear and
the M343. Table 1-1 shows the minimum speed required (in RPM) for the
DST-2000C to detect rotation for a variety of gear diameters at various air gaps.

 Calibration
• Turn the F-16 power on and verify the Count/Generate switch is in the
Generate position.
• Adjust the F-16 to the full-scale frequency as required by the application. To
compute the full-scale frequency, multiply (the number of discontinuities
sensed) by (the maximum speed) and divide by 60.
Hertz (frequency) = Number of Gear Teeth X RPM divided by 60
• Connect power source to DST-200C
• Turn power on to the DST-2000C.
• Verify that the CW relay energizes.
• Adjust the meter output potentiometer to obtain full-scale deflection on the
G-101 or 5 Vdc on digital voltmeter.
• Reverse the connections of the white and black leads of the transformer and
verify the CCW relay energizes and the CW relay de-energizes.
• Turn the F-16 power off and verify that the CCW relay de-energizes after
approximately 2 seconds.
