POINTS OF CAUTION
■ POWER INPUT RATING & OPERATIONAL RANGE
• Locate the power input rating marked on the product and confirm its operational range as indicated below:
85 – 132V AC rating: 85 – 132V, 47 – 66 Hz, approx. 6VA
12V, 24V and 48V DC rating: Rating ±10%, approx. 3.3W
110V DC rating: 85 – 150V, approx. 3.3W
■ GENERAL PRECAUTIONS
• Before you remove the unit from its base socket or mount it, turn off the power supply and input signal for safety.
■ ENVIRONMENT
• Indoor use.
• When heavy dust or metal particles are present in the air, install the unit inside proper housing with sufficient ventilation.
• Do not install the unit where it is subjected to continuous vibration. Do not subject the unit to physical impact.
• Environmental temperature must be within -5 to +60°C
(23 to 140°F) with relative humidity within 30 to 90% RH in order to ensure adequate life span and operation.
■ WIRING
• Do not install cables close to noise sources (relay drive cable, high frequency line, etc.).
• Do not bind these cables together with those in which noises are present. Do not install them in the same duct.
The shape of base socket may be different for some models.
INSTALLATION
Detach the yellow clamps located at the top and bottom of the unit to separate the body from the base socket.
■ DIN RAIL MOUNTING
Set the base socket so that its
DIN rail adaptor is at the bottom. Position the upper hook at the rear side of base socket on the DIN rail and push in the lower. When removing the socket, push down the
DIN rail adaptor utilizing a minus screwdriver and pull.
■ WALL MOUNTING
Refer to “EXTERNAL DI-
MENSIONS.”

EXPLANATIONS OF TERMS & FUNCTIONS
■ LOW-END CUTOUT
The output frequency is forcibly set to 0 Hz when the input frequency is below the low-end cutout setting by the PU-2x
Programming Unit. It is selectable from 0.3 to 100% of the selected input frequency range (e.g. 30 Hz – 10 kHz for the input frequency range 0 – 10 kHz). Use the same unit as that for the input.
The low-end cutout is reset when the input frequency exceeds the cutout value by 1%. For example, with the input frequency range 0 – 100 kHz, the input span frequency 10 kHz and the low-end cutout set to 1 kHz; the output equals
0 Hz while the input is within 0 – 1 kHz. When it goes higher than 1.1 kHz, the output becomes proportional to the input.
When the input frequency range setting is changed, the low-end cutout value is automatically reset to the default value, 0.3% of the range.
■ SCALING FACTOR, INPUT SPAN FREQUENCY & OUT-
PUT SPAN FREQUENCY
The scaling factor, rate of output frequency divided by input frequency, are determined by two parameters: input span frequency and output span frequency.
Although there are also input zero frequency and output zero frequency, they are fixed to zero (0) Hz.
The output frequency is limited up to 115% of the output span frequency.
■ INPUT/OUTPUT WAVEFORMS
The figure below shows an example of the output waveform when the input is changed from 100% to 0% (0 Hz), with no conversion to one-shot.
The output, as shown in the figure, does not drop to 0 Hz immediately after the input does, but rather decreases gradually down to 0 Hz.
The time required for the output reaches 0 Hz is longer when the input frequency range is lower.
In general, it becomes shorter when the low-end cutout value is greater.

■ DETECTING PULSE EDGE
• Open Collector & Mechanical Contact:
OFF (input monitor LED ON) to ON (input monitor LED
OFF)
• Voltage Pulse
A pulse rise detected when the input voltage goes above the detecting level (input monitor LED ON); a pulse sink detected when it goes below the level (input monitor LED
OFF).
• Two-wire Current Pulse
The input resistor (100 Ω) converts the current signal (0 –
25 mA) into 0 – 2.5 V. A pulse rise detected when the voltage goes above the detecting level (input monitor LED ON); a pulse sink detected when it goes below the level (input monitor LED OFF).

■ CAUTION FOR RS-422 LINE DRIVER PULSE
For RS-422 line driver pulse, the input amplitude, detecting level and noise filter settings are all invalid. However, in order to prevent errors in setting, set these switches as follows:
Input amplitude = 50 – 100 Vp-p (SW=0)
Detecting level = 0V
Noise filter = None

A specific sensitivity scale is applied according to the pulse amplitude setting. The scaled input voltage is then compared to the detecting voltage level (0 – 5 V).
The scaled H level voltage must be equal to or higher than the detecting level so that the pulse state is accurately detected. (Refer to the instruction manual for detailed information about adjusting the detecting level.)

Connect to Terminal 4 of the base socket.
A voltmeter of class 0.5 or better accuracy with pointed probes is required.
1) Connect the negative probe of voltmeter to the terminal 4 of base socket.
2) If you need a noise filter, set the SW1-7 and SW1-8 in advance.
3) Connect the positive probe to the test pin and turn the
Detecting Level Adjustment until the meter shows desired value.
4) Apply input signals and check that input monitor LED
(PL1) blinks according to the input signal.
If the LED does not blink, the detecting level may be out of pulse amplitude range. Check the pulse amplitude and the DC offset again and readjust the detecting level.
■ SENSOR EXCITATION ADJUSTMENT
You can change the sensor excitation voltage with the sensor excitation adj. located behind the front cover. If you need to change it, check that the required current is within the specification.
• How to Change the Excitation
A voltmeter and ammeter of class 0.5 or better accuracy are required.
