(rotary switch adjustment) MODEL ASWL2
INSTRUCTION MANUAL
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 bot-
tom. Position the upper hook at
the rear side of
base socket on the DIN rail and
push in the lower. When remov-
ing the socket, push down the
DIN rail
adaptor utilizing a screwdriver
(–) and pull.
n WALL MOUNTING
Refer to “EXTERNAL DIMEN-
SIONS.”

POINTS OF CAUTION
nCONFORMITY WITH EC DIRECTIVES
• This equipment is suitable for Pollution Degree 2 and Instal-
lation 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 re enclosure.
• Altitude up to 2000 meters
• The equipment must be installed such that appropriate clear-
ance and creepage distances are maintained to conform to CE
requirements. Failure to observe these requirements may
invalidate the CE conformance.
nPOWER 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.
Input Resistor
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.

TERMINAL CONNECTIONS
Connect the unit as in the diagram below or refer to the connec-
tion diagram label on top of the unit.
When an input resistor is provided with the module, attach it
together with input wiring to the input screw terminals.
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.
