M-system AYDV is a deviation alarm device used to monitor input signals and trigger alarms when the input deviates from the setpoints by a specified amount. It features:
- Two setpoint adjustments for setting alarm thresholds
- LED indicators for each relay, showing when the alarm is triggered
- Output relays for controlling external devices
- DIN rail mounting for easy installation
Typical use cases include:
- Monitoring process variables such as temperature, pressure, or flow rate and triggering alarms when they exceed or fall below critical values.
- Detecting deviations in production line equipment and activating alarms to minimize downtime.

• Explanations
Setpoint 1 and Setpoint 2 Adjustments are used to set the
alarm setpoints.
A -5 – +5V DC is output at the setpoint monitor jacks across
the COM jack, proportional to the setpoint -50 – +50%.
The LED lights turn on when the coil for each relay is
energized.
• Examples
For setting the setpoint 1 relay to trip above 20% deviation,
turn Setpoint 1 Adj. until you read 2.0V at Setpoint 1
Monitor.
INSTALLATION
Detach the yellow clamps lo-
cated 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 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 adaptor utilizing a screw-
driver (–) and pull.

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) Alarm operations: Check the alarm operations referring
to the figure below.
4) Output load: Check that the output load is 380V AC/
100VA or 125V DC/30W at the maximum. For maximum
relay life with inductive load, external protection is recom-
mended.
ALARM RELAY OPERATIONS
Trip Operation in Power Failure
•Output 1: (9 – 10) turn ON with code 1
(9 – 11) turn ON with code 2
•Output 2: (1 – 2) turn ON with code 1
(1 – 3) turn ON with code 2
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
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.
MAINTENANCE
Regular calibration procedure is explained below:
■ 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 relay trips at the Hi setpoint (Measure the
voltage at the Hi setpoint monitor jacks).
• Lo Setpoint
Decrease the input signal from a value higher than the
setpoint and check that the relay trips at the Lo setpoint
(Measure the voltage at the Lo setpoint monitor jacks).
When the setpoints are shifted, recalibrate the unit according
to the "ADJUSTMENT PROCEDURE" explained earlier.
