10.5 Substitution of a coil
10.5.1 Coils
There are 4 different coils, depending on their diameter: 145, 180, 210 and 260 mm. The last one is a
dual coil (inner and outer), so it includes 4 wires for power supply, but only one wire for temperature
sensor. The others are “single” coils, and include only 2 wires for power supply, and one for temperature
sensor.
Single coils needs no additional care when changing: simply connect each of the 2 power wires in each
of the 2 metallic “towers” placed on the IPC board, while the temperature sensor is connected in its
connector near the “towers”.
Substitution of a dual coil is described in the following section.
10.5.2 Substitution of a dual coil
One IPC can drive either 2 single coils, or only 1 dual coil. A dual coil has 4 power wires that must be
connected following a specific way. Also the temperature sensor has to be connected to a specific
connector.
When connecting a dual coil, the temperature sensor (NTC) must be connected in
channel 2 inside the IPC, that means, in the connector J605 near towers T3A and T3B.
The other connector J604 near towers T2A and T2B (channel 1) must be left free. Details
are shown in the next pictures.
