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
12, 24 and 48V DC ratings: Rating ±10%, approx. 3.3W
110V DC rating: 85 – 150V DC, 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.
■AND ....
• The unit is designed to function as soon as power is sup-
plied, however, a warm up for 10 minutes is required for
satisfying complete performance described in the data

EXPLANATIONS OF TERMS & FUNCTIONS
■COUNT OVERFLOW
Three overflow modes are selectable with the Programming
Unit: Reset, Hold at 100% or Hold at 115%.
In Reset mode, the JPQ2 resets pulse count to zero as soon
as the input reaches the span count value. The span count
is equal to the zero count, thus the JPQ2 never outputs
100% in this sense.
In Hold at 100% mode, the JPQ2 stops counting at 100%
input. The count is held at the span count value, and the
DC output is held at 100%.
In Hold at 115% mode, the JPQ2 continues counting until
115% before holding the count and DC output.
In both modes, the Reset command input resets the count
to zero and the JPQ2 returns to the output equivalent to
zero count.
Input frequency does not affect the pulse counting of this
unit, however, the minimum of 5-microsecond pulse width
(50 msec. for mechanical contact input) is required to ac-
curately count the input pulses.

■ALARM OUTPUT
Either Hi or Lo alarm output is supplied by a relay contact.
The alarm setpoint and the deadband (hysteresis) are ad-
justable with the Programming Unit in percentage of the
input range. The alarm setpoint is selectable from -15 to
+115%, while the deadband is from 0 to 20%.
Once the relay contact trips, it is reset to the normal posi-
tion when the counter is reset by the external reset com-
mand.
■RESET INPUT
When a reset input is turned on, the accumulated count
in the internal counter goes back to zero. The JPQ2 com-
pares the input to this internal count for the alarm function,
therefore is affected by reset operations.
The reset input negative is connected to the input common.
Short across the terminals 6 and 11 for the minimum of
500 msec.
■ZERO COUNT, SPAN COUNT
The count value equivalent to 0% output is called ‘Zero
Count,’ while that equivalent to 100% is called ‘Span Count.’
The zero count is usually set to 0, and selectable up to one
count below the span count. The span count is selectable
from one count above the zero count up to 99999999.
When a reset input is turned on, the output goes to 0% ac-
cording to the reset count.
With the ‘Hold at 115%’ overflow mode, the maximum count
range is from 0 to 99999999, and the maximum effective
count is 114999998.
■DETECTING PULSE EDGE
• Open Collector & Mechanical Contact:
OFF (input monitor LED ON) to ON (input monitor LED
OFF) or ON to 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 (100Ω) converts the current signal (0 –
25mA) into 0 – 2.5V. A pulse rise detected when the volt-
age goes above the detecting level (input monitor LED ON);
a pulse sink detected when it goes below the level (input
monitor LED OFF).

mechanical contact or two-wire current pulse input, set the
switch to 7. DO NOT SET to 8 or 9. The power supply to the
unit must be turned off when changing the setting.

DC Offset (V)*2×Sensitivity Scale
Adjust the detecting level to the value
calculated above following the procedure
explained below.
Confirm open collector or
mechanical contact input.
Adjust the detecting level to
2.0V.
Voltage or two-wire current
pulse input?
No
Yes
*1. Divide a two-wire current pulse input (mA) by 10 and convert it into voltage (V).
*2. Rounded off to one decimal place.

A specific sensitivity scale is applied according to the pulse
amplitude setting. The scaled input voltage is then com-
pared to the preset detecting level.
With DC coupling, the scaled H level voltage must be higher
than the detecting level so that the pulse state is accurately
detected.

Voltmeter
A voltmeter of class 0.5 or better accuracy with pointed
probes is required.
1) Connect the negative probe of voltmeter to the terminal 6
of base socket.
2) If you need a noise filter, set the SW4 and SW5 in ad-
vance.
3) Connect the positive probe to the test pin and turn the
Detecting Level Adjustment until the meter shows de-
sired 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 sen-
sor 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.
1) Connect the voltmeter across the terminals 4 – 6.
2) Connect the ammeter to terminal 4.
3) Turn the potentiometer until the meter shows the de-
sired value.
Check that the current value indicated on the ammeter
is within the allowable limit. If the value is greater than
the limit, lower the voltage value or connect a separate
power source. Otherwise, the transmitter may fail.

■ANALOG OUTPUT ADJUSTMENT
This unit is calibrated at the factory to meet the ordered
specifications, therefore you usually do not need any cali-
bration.
For matching the signal to a receiving instrument or in case
of regular calibration, adjust the output as explained in the
following.
• How to Calibrate The Output Signal
Use a signal source and measuring instruments of sufficient
accuracy level. Turn the power supply on and warm up for
more than 10 minutes.
1) ZERO: Apply the number of pulses equivalent to zero
count (or set the input count to zero count using the Pro-
gramming Unit) and adjust output to 0%.
2) SPAN: Apply the number of pulses equivalent to span
count (or set the input count to span count using the Pro-
gramming Unit) and adjust output to 100%.
3) Check ZERO adjustment again with zero count.
4) When ZERO value is changed, repeat the above proce-
dure 1) – 3).

CHECKING
1) Terminal wiring: Check that all cables are correctly con-
nected according to the connection diagram.
2) Power input voltage: Check voltage across the terminal
7 – 8 with a multimeter.
3) Input: Check that the input signal is within 0 – 100% of
the full-scale.
4) Output: Check that the load resistance meets the de-
scribed specifications.
MAINTENANCE
Regular calibration procedure is explained below:
■CALIBRATION
Warm up the unit for at least 10 minutes. Apply 0%, 25%,
50%, 75% and 100% input signal. Check that the output
signal for the respective input signal remains within accu-
racy described in the data sheet. When the output is out of
tolerance, recalibrate the unit according to the “ANALOG
OUTPUT ADJUSTMENT” procedure.
LIGHTNING SURGE PROTECTION
