Table 37 QS871 J1 Signal Description
6 OS Open String (OS) alarm input for external battery disconnect switch; Alarms on
closure to the non-grounded “Battery” side of the DC bus (-48V).
7 FAJ General purpose Fuse Alarm Major (FAJ) alarm input; Major alarm on closure to
the non-grounded “Battery” side of the DC bus (-48V).
8 SHLF_ID3 Signal used for identifying the board. Pulled up or down on board accordingly in
the factory.
9 RS485+ B Inverting Driver Output / Inverting Receiver Input
10 RS485- A Non-inverting Receiver Input/ Non-inverting Driver Output
J2
Provides the contactor management interface for control and LVD status.
Table 38 QS871 J2 Signal Description
Pin # Signal Name Signal Description
1 LVD_COIL Positive voltage applied to Low Voltage Disconnect Coil. Connect to positive
side of contactor coil.
2 LVD_COILRTN Contactor coil return to VBUS- potential through circuitry. Connect to most
negative side of Contactor coil, other side of coil connected to VBus(+).
3 LVD _NC Normally Closed contactor status monitor. Closed to LVD_C when contactor is
open. Connect signal to NC pin of micro- switch of Contactor.
4 LVD_NO Normally Open contactor status monitor indicator. Closed to LVD_C when
contactor is closed. Connect signal to NO pin of micro-switch of contactor.
Note: The common or return of the micro switch for these signals must be attached to Vbus- in the system
outside of this board.
J3
Connection that provides field access to External Auxiliary Fuse Alarm Major and the Remote LVD input.
