Operation (next)
Gas electrovalve set Y1/Y2 :
Connected to the RV0541 gas ignitor (5 and 6), the Y1/Y2 electrovalve is activated when
heating initiation is requested.
electrode set e1/e2/e3 :
Connected to the RV0541 gas ignitor (10 and HT), the E1/E2 electrode is used to create the
electric arc required by gas combustion, and the E3 electrode to detect the presence of a
flame on the gas ramp.
pressostat B4 :
Connected to the A2 ironer interconnection board (J19-3 & J19-4), the B4 pressostat stops the
heating when there is a depression of gas.
Temperature sensors B20, B21 & B22 :
Connected to A1 control display (X2), the three temperature sensors B20 left sensor (T1), B21
center sensor (T2) and B22 right sensor (T3) are used by A1 control display to regulate the
temperature of the ironing cylinder.
Overheating condition :
Overheating on side = 1 when T1 > 225 °c ou T3 > 225 °c
= 0 when T1 et T3 < 195 °c
Overheating on center = 1 when T2 > 244 °c
= 0 when T2 < 244 °c
Temperature safety sensors B3 :
Connected to A1 control display (X11-4 and X11-5), safety sensor B3 is used by A1 control
display to stop the machine’s heating when the temperature of the ironing cylinder exceeds
240°C.
