2.2 List of parameters
Description: Sets the signal source to activate the DC link fast discharge.
The DC link fast discharge is started later with delay time (p3862) when the following conditions apply:
- BI: p3863 = 1 signal.
- an external line contactor is opened via r0863.1 "energize contactor".
The DC link fast discharge is interrupted when the following conditions apply:
- BI: p3863 = 0 signal.
- ON command for the infeed.
Recommendation: The DC link fast discharge should be activated if there is an external line contactor and is correctly interconnected
(r0863.1, p0860). If the DC link fast discharge is not activated together with an external line contactor, then faults can
occur when precharging (e.g. F30027).
Dependency: Refer to: r3864
Refer to: F30027
Note: The DC link fast discharge is only possible for "booksize" formats. This function is not supported for "chassis"
formats.
Description: Signal to control (energize) terminal X21.2 "DC link fast discharge" on the Braking Module.
This binector output is used as signal source to interconnect to a digital output. The digital output must be connected
to terminal X21.2 of the particular Braking Module.
Dependency: Refer to: p3863
Refer to: F30027
Warning: It must be carefully ensured that the binector outputs BO: p3864.n are correctly interconnected and also that the
appropriate digital outputs are correctly connected up.
If the interconnection/connection is incorrect, in the case of an active DC link fast discharge, the software could
execute another function (incorrect function) via binector outputs BO: p3864.n or could also permanently control the
DC link fast discharge even if the line contactor is closed.
Note: The DC link fast discharge is only possible for "booksize" formats. This function is not supported for "chassis"
formats.
