The boards must be installed in a cabinet.
It has dry contacts for displaying three parameters: unit operation, sensor faults
and fan stage faults.
For units with a motherboard and a daughterboard. It has dry contacts for
displaying two parameters: sensor faults and fan stage faults.

Single-pair shielded cable required. Capacitance between wire and shield:

Ω
/
km.
Examples: Filotex FMA 2P or Filotex IBM 7 362 211.
The shield must be connected at each end to the 0 V line (terminal 3 on J13 or
J12) on the units and the earth to the PLC end. The shielding braid must be as
short as possible (2 cm max.).
The cables must be routed at a distance of at least 30 cm from the power
cables. However, if a power cable intersects with a computer cable, they must
do so at a right angle.
For distances of less than 30 metres, use a shielded cable and keep it at least
30 cm away cm from all lines that could generate interference.
For distances of over 30 metres, install a relay for each input near the board.
Signal output of 0/10 V. Minimum VFD input impedance of 1 k
