■INSTRUCTION MANUAL
This manual describes necessary points of caution when
you use this product, including installation, connection and
basic maintenance procedures.
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:
24V DC rating: 24V ±10%, approx. 80mA
■GENERAL PRECAUTIONS
• Before you remove the unit 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 +55°C
(23 to 131°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
sheet.

Torque: 0.8 N·m
JUMPER SETTINGS
4 kΩ is attached for open collector and mechanical contact
input, while 200 Ω, 510 Ω or 1 kΩ is attached for two-wire
current pulse input.
Resistance can be changed by modifying jumper combina-
tions as shown in the table below.

CHECKING
1) Terminal wiring: Check that all cables are correctly con-
nected according to the connection diagram.
2) Power input voltage: Check voltage supplied to the rack
(model: 18BXx or 18KBXx). For the DC power source, be
sure that the ripple level is within 10% p-p.
3) Input: For the mechanical contact input, check that the
input frequency is 5 Hz or less and the pulse width is 20
msec. or more.
For the open collector input, check that the input fre-
quency is 10 kHz or less and the pulse width is 20 μsec.
or more.
For the voltage pulse input or two-wire current pulse in-
put, be sure that the input signal is as shown in the table
below.
• Waveform requirements

FREQUENCY RANGE AMPLITUDE PULSE WIDTH & DUTY RATIO
0 to 10 kHz 1 to 3V p-p Duty 50 ±10%
0 to 10 kHz Min. 3V p-p Min. 60 μsec.*
* When the frequency is 6 kHz or more, the pulse width is 30
μsec. or more.
Sine or similar waveform
FREQUENCY RANGE AMPLITUDE PULSE WIDTH & DUTY RATIO
50 Hz to 10 kHz 1 to 3V p-p –

4) Output: Check that the output voltage is 0 V at ON, 30 V
DC or less at OFF.
Check also that the output current is 100 mA or less at
ON, 0 mA at OFF.
