Single-Phase Electrical System; Q1 - Main Switch; F1 And F2 - Protection Fuses Of The High-Tension Circuit And Of The Mandrel Rotation Motor; Q2 - Thermal-Magnetic Motor Protector For The Protection Of The Hydraulic Pump Motor - Bosch TCE 5310 Instrucciones De Reparacion

In case the 1° and 2° speed commutator motor has to be replaced follow the connection diagram shown below.
3.8

Single-phase electrical system

The electrical system that is being used is protected by fuses and thermal-magnetic circuit breakers, so, in case of
malfunctions, always disconnect the tyre changer from the power network.
Description and function of the components:
3.8.1

Q1 - main switch

In normal operating conditions has to be set on 1 ON. This device powers up or off the entire electrical circuit.
3.8.2

F1 and F2 - protection fuses of the high-tension circuit and of the mandrel rotation motor

In case it is necessary to reverse the rotation direction of the motor follow the attached connection diagram.
3.8.3

Q2 - thermal-magnetic motor protector for the protection of the hydraulic pump motor

If activated, check the connections of the motor, its energy absorption and the correct calibration of the device
according to the characteristics of the motor. In case it is necessary to reverse the rotation direction of the motor
follow the attached connection diagram.
3.8.4

F4 and F5 - protection fuses of the primary circuit of the tension transformer (T 100VA)

If the fuses burn, usually because of a tension surge, power supply will be missing to all the low-tension circuit,
both 24VDC and 24VAC, so nothing will work except for the hydraulic pump.
3.8.5

F6 - protection fuse of the low-tension 24VDC circuit

In case this one blows all the hydraulic motion won't work, all other will remain active like the mandrel rotation.
Check that the connection cable of the pedal box is not damaged and that the cables inside are not interrupted or
