SIGNAL TRANSMITTER
BEFORE USE ....
Thank you for choosing M-System. Before use, check the
package you received as 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 + input resistor) ..... (1)
The resistor is provided only with current input type.
■ MODEL NO.
Check that model No. described on specification label is
exactly what you ordered.
■ INSTRUCTION MANUAL
This manual describes necessary points of caution when you
use this product, installation, connection and basic maintenance procedures.
POINTS OF CAUTION
■ CONFORMITY WITH EC DIRECTIVES
• This equipment is suitable for use in Pollution Degree 2
environment and in Installation Category II, with the maximum operating voltage 300V.
Basic insulation is maintained between the input and output.
Prior to installation, check that the insulation class of this
unit satisfies the system requirements.
• Altitude up to 2000 meters
• The equipment must be mounted inside a panel.
• The equipment must be installed such that appropriate
clearance and creepage distances are maintained to conform
to CE requirements. Failure to observe these requirements
may invalidate the CE conformance.
• Insert noise filters for the signal input and output connected to the unit. TDK Model ZCAT 3035-1330 or equivalent is recommended.
• The actual installation environments such as panel configurations, connected devices, connected wires, may affect
the protection level of this unit when it is integrated in a
panel system. The user may have to review the CE requirements in regard to the whole system and employ additional
protective measures to ensure the CE conformity.
■ POWER INPUT RATINGS
• Operational range & power consumption: Check the power
rating for the unit on the specification label.
AC ratings: Rating ±10%, 50/60 ±2 Hz, approx. 2VA
DC ratings: Rating ±10%, approx. 2W
SVF
MODEL
(high speed response; isolated)
• 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 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.

INSTALLATION
Detach the yellow clamps located at the top and bottom of the
unit for separating 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 screwdriver
(–) and pull.

Remark: The SVF, due to its fast-response design, does not
eliminate noises included in the input signal. Use shielded
twisted-pair cable for preventing them.

CHECKING
1) Terminal wiring: Check that all cables are correctly
connected 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 described specifications.
ADJUSTMENT PROCEDURE
This unit is calibrated at the factory to meet the ordered
specifications, therefore you usually do not need any calibration.
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 procedure
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 accuracy described in the data sheet. When the output is out of
tolerance, recalibrate the unit according to the "ADJUSTMENT PROCEDURE" explained earlier.
