General safety instructions
Recognised codes of engineering practice, especially the safety requirements
and accident prevention regulations must be observed when performing all
assembly, wiring and commissioning procedures.
Only specially trained and qualified personnel are permitted to perform the
assembly, wiring and commissioning.
The electrical installations must be implemented in compliance with the
current valid EN / VDE / DIN and local electrical regulations.
Danger:
Electric shock by touching live parts.
Electrical devices may cause electrical hazards during operation
Before installation/assembly works begin:
Disconnect all poles or switch off supply voltage of EASYLAB controller.
Protect power supply against unauthorised or unintended restart.
All installation operations may only start after these safety operations.

- 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

Special functions – Room controller Part 1
Control of on-site provided sun blind control device
(only at room controller with activated RMF and alternative to
Activation/Deactivation of supply air diffusors and Operation mode dependent
switching)
-Button function-
DO5 or DO6 activated as long as button is pressed
Control of on-site provided lighting / device (only at room controller with activated RMF)
For safety reasons the TCU3 casing must be locked in such a way that it can
only be opened with a tool when a 230 V power supply is connected.
A safety latch with a sticker is available, which can be ordered under EM-TRF-
Zubehoer (A00000055540).
When delivered with transformer module EM-TRF or EM-TRF-USV, this is installed
and is not required additionally.

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) -
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.
