INSTRUCTION MANUAL
This manual describes necessary points of caution when you
use this product, installation, connection and basic mainte-
nance procedures.
POINTS OF CAUTION
POWER INPUT RATINGS
• Power input ratings are specified by the model number
suffix code. Check the power input voltage for the unit on the
specification label.
24V DC ±10%, approx. 35mA with Voltage Output 1
approx. 55mA with Current Output 1
GENERAL
• 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 and ventilate it.
• Do not install the unit where it is subjected to continuous
vibration. Do not apply physical impact to the unit.
• 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 (power supply, input and output) 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
supplied, however, a warm up for 10 minutes is required for
satisfying complete performance described in the data sheet.

CHECKING
1) Terminal wiring: Check that all cables are correctly
connected according to the connection diagram.
2) Power input voltage: Check voltage supplied to the rack
(model: 10BX ). For the DC power source, be sure that
the ripple level is within 10% p-p.
3) Input: Check voltage across the terminal 2 (+) – 3 (–) with
a voltmeter to show 0V at 0% potentiometer input and the
same voltage as that across 1 (+) – 3 (–) at 100% input.
4) Output: Check that the load resistance meets the de-
scribed specifications.
