Signal contact "Ready BTB/RDY" (Solid state relay)
Hardware: Safety circuit with solid state relay contact
Software: State signal parameter state RDY ( 0x40 Bit14 )
ready BTB = logic 1
In case of errors this safety circuit is separated by the relay and the state 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 mF
Contact resistor
max. 2 Ohm
Ready BTB
The BTB relay contact is closed.
Not ready
BTB relay contact is open.
Red LED and error message via
7-segment state LED.
Always install the
BTB/RDY contact in the
safety circuit!
Protect the BTB/RDY
signal path by a
fuse 0.5 AF!
BTB function with under-voltage monitoring
BTB signal even with the power voltage missing.
Programming in NDrive: parameter BTB power = without (0x5a Bit 5 = 1)
No BTB signal if the power voltage is missing.
Programming in NDrive: parameter BTB power = with (0x5a Bit 5 = 0)
(see Manual NDrive-x)
