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.
n PACKAGE INCLUDES:
Signal conditioner (body + base socket + input resistor).....(1)
Input resistor is provided only with current input type.
n MODEL NO.
Check that model No. described on specification label is exactly what you ordered.
n INSTRUCTION MANUAL
This manual describes necessary points of caution when you use this product, installation, connection and basic maintenance procedures.
POINTS OF CAUTION
n CONFORMITY WITH EC DIRECTIVES
• This equipment is suitable for Pollution Degree 2 and Installation Category II.
The relay output circuit is suitable for use in Pollution Degree
2 environment in Over Voltage Category II with the maximum operating voltage 150V, in Over Voltage Category I with 240V.
Reinforced insulation (signal input or output to power input:
300V) and basic insulation (signal input to output: 300V) are maintained. Prior to installation, check that the insulation class of this unit satisfies the system requirements.
• The equipment must be mounted inside a suitable fire enclosure.
• Altitude up to 2000 meters
• 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. n POWER INPUT RATINGS
• Operational range & power consumption: Check the power rating for the unit on the specification label.
AC rating: Rating ±10%, 50/60 ±2 Hz, approx. 2VA
DC rating: Rating ±10%, approx. 2W n GENERAL
• Before you remove the unit from its base socket or mount it, turn off the power supply and input signal for safety.
n 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 +60°C (23 to 140°F) with relative humidity within 30 – 90% RH in order to ensure adequate life span and operation.
MODEL
ASWL2 n 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.
n 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.
n 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.

FRONT PANEL CONFIGURATION
• Explanations
Hi and Lo setpoint rotary switches are used to set the alarm setpoints.
The Hi and Lo LED lights turn on when the coil for each relay is energized.
• Examples
For setting the relay to trip above 80% of the full-scale input signal, set the Hi rotary switch (x10) to "8", while the switch (x1) to "0".

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
– 14 with a multimeter.
3) Input: Check that the input signal is within 0 – 100% of the full scale.
4) Alarm operations: Check the alarm operations referring to the figure below.
5) Output load: Check that the output load is 380V AC/120VA or
125V DC/30W at the maximum (≤0.5A). For maximum relay life with inductive load, external protection is recommended.

MAINTENANCE
Regular calibration procedure is explained below: n CALIBRATION
Warm up the unit for at least 10 minutes.
• Hi Setpoint
Increase the input signal from a value lower than the setpoint and check that the trip point remains within the accuracy described in the data sheet.
• Lo Setpoint
Decrease the input signal from a value higher than the setpoint and check that the trip point remains within the accuracy described in the data sheet.
When the trip points are out of tolerance, contact M-System's Sales
Office or local representatives.
