5.2 RESET and Contactor Control

- X2/5
- X2/21 to X2/24
A rising 24V front applied to X2/5 as compared to X2/21 induces the reset after a fault.
Its worth noting that the reset can also be carried out by turning off the power supply completely
(mains and auxiliaries).
This control has no effect during normal operation. The system must be "reset" after any active
fault.
- X2/6
- X2/18
•
This logic output is at level 0 if:
• the amplifier has neither low levels or neither power on the amplifier
• the amplifier has low levels without power.
•
This logic output is at level 1 if:
• The dc bus voltage is present and the amplifier does not display a fault
•
This logic output shifts from level 0 to level 1 on the setting up of a power bus, due to the
closing of the main contactor (KM power contactor)
This output must, through an interface, authorise the self-support of the main contactor.
This logic output shifts from level 1 to level 0 in the folowing cases:
• On normal stoppage, obtained by voluntary opening of the main contactor, when the dc
bus voltage shifts to the minimum value of authorised bus voltage.
• On amplifier fault requiring amplifier stoppage.
Caution: The shift to 0 of this logic output during running must imperatively induce the
opening of the main contactor, with a maximum delay of 100ms.
