3.10.13 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.
3.10.14 Q2 - thermal-magnetic motor protector for the protection of the hydraulic pump motor
If activated, verify 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.
3.10.15 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.
3.10.16 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
short-circuited. Rare, but in any case possible, check the electromagnetic coils of the electrovalves or the micro
switches on the pedal box that can short-circuit if damaged.
3.10.17 F7 - protection fuse of the 24VAC circuit
In case it blows check that the connection cable of the pedal box is not damaged and that the cables inside are
not interrupted or short-circuited, and that the micro switches on the pedal box are not short-circuited if they are
damaged. Finally, check also the two remote control switches of the rotation mandrel, specially the coils.
!
With this type of single-phase machinery be very careful when operating on the motor condensers, since they
retain for a long time the residual electrical charge, and therefore subsists the danger of electrical discharges of
considerable intensity if they are inadvertently touched.
