surge protector with its maximum surge voltage 40V or less
between lines. Recommended M-System model: MDP-D24.
■ POWER INPUT RATING & OPERATIONAL RANGE
• Check the power rating for the unit on the specification label.
85 – 132V AC rating: 85 – 132V, 47 – 66 Hz, approx. 5.5VA
12, 24, and 48V DC ratings: Rating ±10%, approx. 3.3W
110V DC rating: 85 – 150V DC, approx. 3.3W
■ UNPLUGGING THE UNIT
• 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 ventila-
tion.
• 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 (power supply, input and output) close
to noise sources (relay drive cable, high frequency line, etc.).
• Do not bind the unit's cables together with cables where
high noise levels are present. Do not install them in the same
duct.
■ AND ....
• The unit is designed to function as soon as power is
supplied, however, a warm up for 10 minutes is required for
satisfying complete performance described in the data sheet.

HARDWARE SETTING & CALIBRATION
■ SW1 & 2 FUNCTIONS (SW1: Input 2, SW2: Input 1, SW1-3 and SW2-3 are used commonly to both inputs.)
■ INPUT FILTER
The tables below show the maximum frequency which can
pass through the filter when the sensitivity level is set to 2V.
The frequency may change according to the sensitivity level.
After turning the filter ON, check that the PL1 and PL2 blink
according to the input signals. If they do not, readjust the
sensitivity according to the instructions in the following
section.

EM-1693 Rev.7P. 5 / 6
■ SENSITIVITY ADJUSTMENT
You can change the detection level with the sensitivity adj.
located behind the front cover. The VHdetermines the pulse
rise and the VLdetermines the pulse fall. With SW1/2-7 set
to ON, the input signal is scaled down by 1/2 (1/3 for the model
number suffix code A). Be sure that the sensitivity levels are
also scaled down by 1/2 (1/3 for the model number suffix code
A). See the Ordering Information Sheet included in the
package for the factory settings.
For the RS-422 line driver pulse input, there is no need of
adjustment because a line receiver conforming with the RS-
422 standard is incorporated.
•How to Change the Sensitivity
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
(6) of base socket. See the figure to the right.
2) If you need a noise filter, turn on the SW1/2–5 or SW1/2–
6.
3) Connect the positive probe to the test hole No. 2 and turn
the VHpotentiometer until the meter shows desired
value.***
4) Connect the positive probe to the test hole No. 3 and turn
the VLpotentiometer until the meter shows desired
value.***
5) Apply input signal and check that input monitor LED
(PL1 or PL2) blinks according to the input signal.****
***For the VH(VL) sensitivity level less than 5V, turn off the
SW2–3 (SW1-–3). For less than 10V, turn on the SW2–3
(SW1–3).
The voltage values approx. half the amplitude are recom-
mended for normal use.
You had better have a reasonable span between VHand VLin
order to prevent noise interference.
****If the LED does not blink correctly, the sensitivity level
may be out of the pulse amplitude. Check the offset, ampli-
tude, etc. and go through the adjustment procedure again.

■ 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.
1) Connect the voltmeter across the terminals 9 – 6.
2) Connect the ammeter to terminal 9.
3) Turn the potentiometer until the meter shows the desired
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.
