3] Introduction:
Thermoscan (ETS- TSN) is microcontroller based electronic device which interfaced with thermolog with
RS485 port. It is an updated hardware plus firmware version of thermoscan, with fast sensor scanning and
three wire compensation facility. Can be configured for 8 channel stability (8 channel temperature+8 channel
humidity) also it has enhanced with easy to use tactile membrane keypad plus sticker.

8.2 Installation Note:
While installing this system one must take care of following points.
All cables connecting to “thermoscan “must lay separately, they should not mix up with high
voltage & high current cables (like Motor; compressor; contactor; Heater etc.

There should be a proper insulation for sensor wires to avoid noise interrupt.

Take care while laying cables for Thermoscan interface with thermolog; as these cables are very
sensitive to noise. Do not connect RS-485 cables in Star network; connect in loop network.
o Maximum distance for thermolog to thermoscan communication cable is 600 mtr. This cable
must not be routed along with power cable.

o Cable specification for RS-485 => 14/36; 22AWG; 2 core shielded twisted cable.

RTD-PT100 sensor Cable length: 100metre MAX.

0 to 1V humidity sensor cable length: 3 meter max (keep as short as possible.)
0 to 3.3V humidity sensor cable length: 3 meter max (keep as short as possible.)

4 to 20mA sensor cable length: 3 meter max (keep as short as possible.)
