Power
Battery power must be supplied to designated power-up digital inputs, since the controller's 3 to 12 Vdc
regulated power supply is not available when the controller is in lower power mode.
Module supply voltage/maximum current ratings
PLUS+1
®
modules are designed to operate with a nominal 7 to 36 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 pins must be
connected to the vehicle power supply to support advertised module maximum output current capacity.
DO NOT use module power pins to supply power to other modules on a machine.
Lower power mode
This feature gives OEM designers the ability to implement automotive-like features in their machine
control system design. If the lower power mode feature is not implemented, this controller has the same
operating characteristics as any other PLUS+1
®
controller.
When used as a lower power mode controller, supply power to the module is connected directly to the
battery. Lower power mode initiation is defined by the controller's application software: PLUS+1
®
GUIDE
programmers define the conditions under which the controller is to put into lower power mode. When in
lower power mode, controller outputs are set to zero, sensor power supply is off and the controller
consumes a small amount of current.
