Instruction manual

1-14 / Introduction ControlWaveLP
1.3.2.1 PSSB Switches
SPDT Switch SW1 is used to connect the MOSFET power switch gate to PSGND when the
‘I’ side of the switch has been pressed to its actuated position.
1.3.2.2 PSSB Board Jumpers
The PSSB Board contains the following Jumpers (situated on the bottom of the PCB):
JP1 - Watchdog Relay Enabled = position 1-2, Disabled = position 2-3
JP2 - -12V Enabled = position 1-2, Disabled = position 2-3
JP3 - +12V Enabled = position 1-2, Disabled = position 2-3
JP4 - 50mA Load Enabled = position 1-2, Disabled = position 2-3
JP5 - +12V Seq. Monitor Enabled = position 1-2, Disabled = position 2-3
JP6 - -12V Seq. Monitor Enabled = position 1-2, Disabled = position 2-3
1.3.2.3 PSSB Board Fuse F1
Slow Blow Fuse F1 is rated at 10A for a 12V system or 3A for a 24V system.
1.3.2.4 PSSB Board Connectors
PSSB Bd. Terminal Block Connector TB1
TB1 provides 3 Watchdog Relay connections or 2 MOSFET connections:
Relay Connections (Figure 2-19:
MOSFET Connections (Figure 2-20):
TB1-1 = N/O - NO Watchdog contact TB1-1 = VO - Watchdog MOSFET Switch Output
TB1-2 = C - Common Watchdog contact TB1-2 = VI - Watchdog MOSFET Switch Input
TB1-3 = N/C - NC Watchdog contact TB2-2 = V- - PSGND (Watchdog Common)
PSSB Bd. Terminal Block Connector TB2
TB2 provides 3 input connections for bulk power:
TB2-1 = 9-30V dc Bulk
TB2-2 = Power Supply Ground - PSGND (VIN-)
TB2-3 = Chassis Ground - CHASSIS
PSSB Bd. Connector J1
Connector J1 is a 20-pin DIP Header that interfaces Power, Ground and power supply
status signals to Connector P9 on the FMI/OB Board (see Table 4-13).
1.3.2.5 PSSB Board Test Points
Six (6) test points are provided on the PSSB Board:
TP1 = VIN+
TP2 = VIN- (PSGND)
TP3 = +5Vdc (Enable JP4 - position 1-2)
TP4 = +12Vdc (Enable JP3 - position 1-2)
TP5 = -12Vdc (Enable JP2 - position 1-2)
TP6 = Ground (GND)
