4.9 - SETUP PROCEDURES WITH THE AID OF THE CONTROL PANEL
1) Enter the theoretical values (see paragraph 4.8 above)
2) Access the DIAGNOSTIC – ANALYSIS submenu (see paragraph 4.8 above)
3) Read the effective pulsed voltage of the strip, THEORETICAL V.
4) Set the transformer secondary voltage allowing for a multiplication coefficient of 1.5 – 2 for pulsed operation and a
coefficient of 1 – 1.5 for continuous operation:
transformer V = strip V x multiplication coefficient (1 – 1.5 - 2), select the nearest one.
4.10 - SETUP PROCEDURES WITHOUT USING THE CONTROL PANEL – MANUAL MODE
Calculating total resistance:
R strip=specific resistance[Ohm/m] x strip length[m]
Calculating the strip cross-section S:
Strip cross-section S[mm
2
]=strip length[mm] x strip thickness[mm]
Calculating the theoretical pulsed heating currents I:
I heating=strip cross-section S[mm
2
] x 30[Amp/ mm
2
]
Calculating the effective pulsed voltage applied to the strip:
V strip=R strip x I heating
Calculating the transformer secondary voltage allowing for a multiplication coefficient of 1.5 – 2 to increase the sealing
speed under pulsed operating conditions and coefficient 1 for continuous operation:
V transformer= V strip x multiplication coefficient (1 – 1.5 - 2)
(select the nearest one)
