GAA330-M EMISSION MONITORING SYSTEM
• Analog outputs: 4 to 20 mA, joint minus pin, electrically isolated, ran-
domly groundable, max. DC 30 V, load max. 600 Ω, resolution 16 bit
Digital relay outputs: Potential-free contacts (powerless status opened,
•
fail safe), max. AC/DC 277 V, max. current AC1 5 A, max. current per
group of 4 AC1 20 A
Digital inputs: Optoelectronic coupler with internal power supply
•
DC 24 V, switched potential-free contacts, Status 0: UL < DC 5 V, Status
1: UH > DC 11 V, I min / max = 2 mA / 4.5 mA
H
Modbus: 9-pole sub-D plug
•
Ethernet: RJ45 female connector
•
Observe the cable specifications.
•
Observe the "Interface plan" in the drawings set.
•
When routing the electrical lines, follow all applicable national safety
•
regulations for the installation and operation of electrical devices.
Follow all regulations and standards for electrical installations on board
•
of ships and observe the local conditions.
Route the signal leads separately from the power supply lines.
•
Locate the analog and digital signal lines separately from each other.
•
Carefully plan the arrangement of signal leads in the cables as well as
•
the use of openings for cable connectors.
Connect the signal leads to the terminal strips.
•
Cable shielding should be connected according to local regulations.
•
Differences in potential and signal interference must be taken into con-
sideration.
Observe the power supply requirements.
•
Before connecting the power supply, make sure the analyzer system
•
operating voltage is set to match the line voltage.
The protective lead connector and protective lead should be connected
•
before any other connection is made. The analyzer system can be haz-
ardous if the protective lead is interrupted inside or outside the system
or if the protective lead is disconnected.
Connect
•
the input wiring of the analyzer cabinet (see below for connection
•
diagrams)
the input wiring of the heated sample components (tempera-
•
ture-resistant as needed)
the Pt100 resistance thermometer leads
•
the input wiring of the back-purging unit (solenoid valves)
•
to the terminal strips.
