Signal contact Ready (Solid State Relais) / Ready BTB / RDY
Hardware safety circuit with solid state relay contact.
Software: State signal Parameter State RDY ( 0x40 Bit 14 )
Ready BTB = logic 1
In case of error this safety circuit is separated by the relay and the status RDY is set to 0.
Further control units (e.g. BMS, VCU etc.) may respond.
Contact for max. 48 V / 0,5 A (not short-circuit proof)
Capacitive load: max. 1 µF
Contact resistance: max. 2 Ω
Ready for BTB
The BTB realy contact is closed.
Not ready
BTB relay contact is open.
Red LED and error message with
Status-7-Segment-LED.
BTB/RDY always insert contact into the safety circuit!
Secure BTB/RDY signal path with 0.5 AF!
BTB function with undervoltage monitoring:
BTB signal even if power voltage is missing.
Programming in NDrive: Parameter BTB Power = without (0x5ABit 5 = 1).
No BTB message if power voltage is missing.
Programming in NDrive: Parameter BTB.Power = with (0x5ABit 5 = 0).
(see Manual NDrive-x)
