Electrical devices may cause electrical hazards during operation
Before installation/assembly works begin:
Disconnect all poles or switch off supply voltage of EASYLAB controller.

Power supply

Supply voltage 24 V AC / DC

Technical data:

• Supply voltage 24 V AC ± 15% 50-60 Hz
• Supply voltage 24 V DC ± 15%
• Fuse 2,5 A slow, 250 V; glass tube fuse 5×20 mm
• Power consumption up to 40 VA (Maximum configuration) inrush current actuator: Imax 20 A for 5 ms
  Only TCU3 without additional configuration: …………………………..5 VA
  Maximum power consumption is determined by the individual controller configuration.
  Typical configurations will lead to following values:
  Fume cupboard controller with control panel ………………….up to 35 VA
  Room controller with room control panel CP-TOUCH………….. up to 33 VA
  Room controller without room control panel ………………….. up to 29 VA
  Supply air/extract air controller without room control panel ….up to 29 VA

Important wiring instructions:
Observe polarity
Polarity of DC and AC supply voltage has to be strictly complied for all controllers during wiring.
Limited wiring in a row
Power supply wiring in a row (via double terminals) is only approved for a maximum of 5 EASYLAB controllers!
Supply voltage at analogue inputs for supply of sensor/transducer
Type of used controller power supply (AC/DC) will influence type of provided power supply at analogue inputs:
TCU3 Power supply 24 V AC → Provided sensor supply at AI1-AI5 is 24 V AC
TCU3 Power supply 24 V DC → Provided sensor supply at AI1-AI5 is 24 V DC
This may require attention for connected sensors

Mains supply voltage 230 V AC

Alternative power supply
(only with expansion module EM-TRF or EM-TRF-USV)

Technical data:

• Supply voltage 230 V AC ± 20% 50-60 Hz
• Fuse 500 mA slow, 250 V
• Power consumption up to 40 VA (Maximum configuration)

Important wiring instruction:

• Never connect 230 V and 24 V supply voltage simultaneous at one controller.
• Never connect 24 V supply voltage at controller with built in expansion module EM-TRF or EM-TRF-USV
  Supply voltage at analogue inputs for supply of sensor/transducer
  TCU3 Power supply 230V AC → Provided sensor supply at AI1-AI5 is 24 V DC (with EM-TRF, EM-TRF-USV)
  This may require attention for connected sensors

Communication line (CL)

Default socket communication line 1
Default socket communication line 2

CL – Termination resistor

Termination of communication line CL
For a correct data exchange of the controllers is a termination on both ends of the communication line required.

Communication line (CL)

CL – Screw terminals as an alternative wiring option:
For data exchange via network cable from a reel as an alternative to patch cables

Important wiring note:
For port COMM1 or COMM2 on one EASYLAB controller use either the RJ45 sockets with patch cable or the screw terminals with network cable from a reel to built up the communication line CL.

Technical data:

• Preessure control via extract air controller ( Supply air controlled system – Clean room)
• available as of TCU3 controller with Software Version 3.0
• Current pressure signal integrateable via analogue signal 0-10V; Characteristic configurable
• 2 independent setpoints with related parameters configurable
• Setpoint changeover via switch contact at DI6 configurable alternatively via Expansion Modul via LonWorks®, BACnet MS/TP, Modbus-RTU, BACnet IP, Modbus IP
• Special functions via door switch contact at DI5 configurable (Alarm handling, Control behaviour en)
• All connections and settings for pressure control within controller with Room-Management-Function (RMF)
• Seperate alarm output DO3 for pressure control loop

1. System design – Pressure control within extract air controlled room (e.g. Laboratory)
   FH: Fume cupboard controller EC: extract air controller RE: Room extract air controller
   PC: Executing pressure controller – Supply air
   Example 1.1: RMF-Function activated on executing pressure controllerExample 1.2: RMF-Function activated on other room controller (not recommended)

2. System design – Pressure control within supply air controlled room (e.g. Clean room)
   FH: Fume cupboard controller SC: Supply air controller RS: Room supply air controller
   PC: Executing pressure controller – Extract air
   

Recommendation:

In tight rooms and for optimal use of the diagnostic functions, the room management function (RMF) should be activated on the operating pressure controller (PC) .

Pressure control connections:

Power supply for pressure transducer
The power supply of the pressure transducer can be provided by the EASYLAB TCU3 via 24V connector of analogue input X5 AI Sensor.
Important:

TCU3 supplied with 24 V AC → Connector 24V of X5 AI Sensor provides 24V AC
TCU3 supplied with 24 V DC → Connector 24V of X5 AI Sensor provides 24V DC
TCU3 supplied with 230V AC → Connector 24V of X5 AI Sensor provides 24V DC.

The above mentioned different supply voltage types must be observed depending on selected pressure transducer type.

Huba Pressure transducer type 699
This transducer is approved for AC and DC power supply type.
Therefore no adaption is required. Briem Pressure transducer type GB604 MF 0,75
This transducer is approved for AC and DC power supply type.
Therefore no adaption is required.
Old Briem transducer must be manually adapted to the power supply type.
Default delivery setting ist AC supply.
Using a 230 V AC supply for the TCU3 via EM-TRF or EM-TRF-USV or 24 V DC supply implies a manual change of the supply to DC type.
Therefore change jumper setting from AC to DC within the Briem transducer casing.

  Usage on controller without RMF
  -> Access to datapoints of single controller

Connection assignment:

Network cable types:
Following cable types are recommended for LonWorks®-networks by Echelon:
TIA 568A Category 5

• 8471 oder 85102 (Belden)
• Level IV cable
• JY(St)Y 2x2x0,8 (use only twisted wire pairs for LON-A and LON-B)
