4 START UP
4.1 - START UP PROCEDURES – INSPECTING THE SYSTEM AND THE PARTS USED
Stage 1 – In order to properly set up the system, read the instructions given in paragraph 4.8 THEORETIC
CALCULATIONS AND DIAGNOSTIC PROCEDURES and 4.9 SETUP PROCEDURES WITH THE AID OF
THE MULTI-LINGUAL CONTROL PANEL
Stage 2 – Use a Low Voltage Unit for power transformer outputs up to 10 Volt
Use a Standard Unit power transformer outputs from 11 to 99 V.
Use a High Voltage Unit for power transformer outputs from 100 to 140 V.
Use Primary mode for pulsed currents more than 220Amps.
Stage 3 – Make the system contructed in an workmanshiplike manner.
Stage 3.1 – Use sealing bands supplied by our Company or equivalent (don’t use NI-CR sealing bands).
Stage 3.2 – The power cable inside the T.A. must not turn around T.A (only 1 single line inside).
Stage 4 – For any further information, call 3E – ENGINEERING DEPARTMENT.
TECHNICAL NOTES
From software V5.1 it’s possible modify the temperature coefficient of the sealing bands in part per milion PPM; modifying
the PPM also other parameters will change in automatic as shown in the following table; for compatibility with the previous
models the thermoregulator outputs from our factory with the default temperature coefficient PPM=1465 that maintain the
heating characteristic and the voltage of the analog input unchanged.
