M-system AS4T

The M-system AS4T is a thermocouple alarm with a variety of features that make it ideal for a variety of applications.

  • Dual or quad alarm trip: The AS4T can be configured to have either two or four alarm trips, making it ideal for applications where multiple temperature zones need to be monitored.
  • Field-configurable: The AS4T can be easily configured in the field using the front panel buttons. This makes it easy to change the alarm setpoints, input type, and other parameters without having to send the unit back to the factory.
  • Compact design: The AS4T is compact in size, making it easy to install in tight spaces. It can be mounted on a DIN rail or on a wall.

■ INSTRUCTION MANUAL
This manual describes necessary points of caution when
you use this product, including installation, connection and
basic maintenance procedures.
POINTS OF CAUTION
■ INSULATION CLASS
•This unit is provided with the class of basic insulation.
Prior to installation, check that the insulation class of this
unit satisfies the system requirements.
■ CONFORMITY WITH LOW VOLTAGE DIRECTIVE OR UL
•ThisequipmentissuitableforuseinaPollutionDegree
2 environment and in Installation Category II, with the
maximum operating voltage of 300V.
Basic insulation is maintained between signal input, out-
put and power input. Prior to installation, check that the
insulation class of this unit satisfies the system require-
ments.
•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 con-
form to CE/UL requirements. Failure to observe these re-
quirements may invalidate the CE/UL conformance.
■ CONFORMITY WITH EMC DIRECTIVE
•Insertanoisefilterforthepowersourceconnectedtothe
unit.Densei-LambdaNoiseFilterModelMZS-1206-33or
equivalent is recommended.
•
The actual installation environments such as panel con-
figurations, 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 re-
quirements in regard to the whole system and employ ad-
ditional protective measures to ensure the CE conformity.
■ POWER INPUT RATING & OPERATIONAL RANGE
•Locatethepowerinputratingmarkedontheproductand
confirm its operational range as indicated below:
100–240VACrating:85–264V,47–66Hz,approx.6VA
(100 – 240V ±10% for UL)

110VDCrating:85–150V,approx.3.5W(110V±10%forUL)
■ GENERAL PRECAUTIONS
•Beforeyouremovetheunitfromitsbasesocketormount
it, turn off the power supply and input signal for safety.
■ ENVIRONMENT
•Indooruse
•Whenheavydustormetalparticlesarepresentintheair,
install the unit inside proper housing with sufficient ven-
tilation.
•Donotinstalltheunitwhereitissubjectedtocontinuous
vibration.Donotsubjecttheunittophysicalimpact.
•Environmentaltemperature must be within-5to+55°C
(23to131°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
