Input Resistor

• Hi Adjustment: Used for adjusting Hi setpoint.

• Lo Adjustment: Used for adjusting Lo setpoint.

• Hi LED: Turns on in a tripped condition.

• Lo LED: Turns on in a tripped condition.

• Hi Setpoint Monitor (+):

Outputs 0 – 10V DC proportional to the setpoint 0 – 100%.

(ex: Set to 8V when you need output ON with input 80% or

more.)

• Lo Setpoint Monitor (+):

Outputs 0 – 10V DC proportional to the setpoint 0 – 100%.

(ex: Set to 2V when you need output ON with input 20% or

less.)

• Common (–): Used for setpoint monitors.

INSTALLATION

Detach the yellow clamps lo-

cated at the top and bottom of

theunitforseparatingthebody

from the base socket.

■ 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 removing the

socket, push down the DIN rail

adaptorutilizingascrewdriver

(–) and pull.

■ WALL MOUNTING

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) Relay operations: Confirm that the relays operate prop-

erly referring to the figure below.

5) Output load: Check the output load corresponds to the

table below.

For maximum relay life with inductive load, external

protection is recommended.

ALARM RELAY OPERATIONS

Trip Operation in Power Failure

•Output Code: 1, 2, 4: both relays turn OFF

•Output Code: 3: both relays turn ON

POINTS OF CAUTION

■ GENERAL

• Before you remove the unit from its base socket or mount it,

turn off the power supply and input signal for safety.

■ ENVIRONMENT

• 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

to140°F) with relativehumidity within 30to 90% RH inorder

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.

MAINTENANCE

Regular calibration procedure is explained below:

■ CALIBRATION

Warm up the unit for at least 10 minutes.

• Hi Setpoint

Increasethe input signalfroma value lowerthan 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.
