Module Supply Voltage/Maximum Current Ratings

PLUS+1 modules are designed to operate with a nominal 9 to 32 Vdc power supply. The modules will
survive with full functionality if the supply voltage remains below 36 Vdc.

Caution
PCB damage may occur. To prevent damage to the module all module power supply + pins must be
connected to the vehicle power supply to support advertised module maximum output current capacity.
DO NOT use module power supply + pins to supply power to other modules on a machine.

MC038-010 Power Supply

The MC038-010 controller's power supply design recommendations must be followed:
•
Power supply to MC038-010 controller's output power planes (C1-p36 to C1-p38) must be wired
directly to the vehicle battery and the wiring runs must be kept as short as possible.
•
Power supply to the controller's DSP (C1-p2) must be wired separately from the power supply to the
controller's output power planes.
•
Do not connect any other PLUS+1 controllers to the power supply to MC038-010 controller's output
power planes.

MC038-010 Sleep Mode

Sleep mode is unique to the MC038-010 controller. This feature gives OEM designers the ability to
implement automotive-like features in their machine control system design. If the sleep mode feature is
not implemented, this controller has the same operating characteristics as any other PLUS+1 controller.
When used as a sleep mode controller, supply power to the MC038-010 is connected directly to the
battery. Sleep mode initiation is defined by the controller's application software: PLUS+1 GUIDE
programmers define the conditions under which the controller is to put to sleep. When in sleep mode,
controller outputs are set to zero, sensor power supply is off and the controller consumes a small amount
of current.

Battery power must be supplied to designated wake-up digital inputs, since the controller's 5 Vdc
regulated power supply is not available when the controller is in sleep mode.
