INSTRUCTION MANUAL
BEFORE USE ....
Thank you for choosing M-System. Before use, please check
contents of the package you received as outlined below.
If you have any problems or questions with the product,
please contact M-System’s Sales Office or representatives.
■ PACKAGE INCLUDES:
Signal conditioner (body + base socket) ...................... (1)
■ MODEL NO.
Confirm Model No. marking on the product to be exactly
what you ordered.
■ INSTRUCTION MANUAL
This manual describes necessary points of caution when
you use this product, including installation, connection and
basic maintenance procedures.
POINTS OF CAUTION
■ NONINCENDIVE APPROVAL OPTION
• This equipment is suitable for use in Class I, Div. 2, Groups
A, B, C and D or Non-Hazardous Locations only.
• WARNING! Before You Remove the Unit from Its Base
Socket or Mount It, Turn Off the Power Supply and Input
Signal for Safety.
• WARNING! – Explosion Hazard –
Substitution of Components May Impair Suitability for
Class I, Div. 2.
• WARNING! – Explosion Hazard –
Do Not Disconnect Equipment Unless Power Has Been
Switched Off or The Area is Known To Be Non-Hazardous.
• The equipment was evaluated for use in the ambient tem-
perature and relative humidity as mentioned in ‘ENVI-
RONMENT’ section.
• The input and output wiring must be in accordance with
Class I, Div. 2 wiring methods and in accordance with the
authority having jurisdiction for use in these hazardous
locations.
■ 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 ven-
tilation.
• 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.
• Be sure that the ventilation slits are not covered with ca-
bles, etc.
■ WIRING
• Do not install cables (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 the input sig-
nal is supplied, however, a warm up for 10 minutes is re-
quired for satisfying complete performance described in
the data sheet.
COMPONENT IDENTIFICATION
INSTALLATION
Loosen the fixing screw at the front of the unit in order 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.”

TERMINAL CONNECTIONS
Connect the unit as in the diagram below or refer to the con-
nection diagram on the side of the unit.
CHECKING
1) Terminal wiring: Check that all cables are correctly con-
nected according to the connection diagram.
2) Input: Check current with an ammeter. Be sure that
the connected transmitter allows the load shown in the
following table.
3) Output: Check that output load is within the permis-
sible limit shown in the following table.
ADJUSTMENT PROCEDURE
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 0% input and adjust output to 0%.
2) SPAN: Apply 100% input and adjust output to 100%.
3) Check ZERO adjustment again with 0% input.
4) When ZERO value is changed, repeat the above proce-
dure 1) – 3).
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 “ADJUST-
MENT PROCEDURE” explained earlier.
