Display Screens Setup Menu Cables and Connectors CA3 vs CA2
CA3 Setup MenuThe setup menu is accessed by pressing and holding the left button for several seconds, or by holding the right button down while the CA is powered up. It is a 2-level deep menu list organized into 13 high level groups to let you adjust over 60 different settings. Remember the left and buttons toggle left and right (or up and down), while pressing and holding the right button selects something.
There are also a few visual cues to help with the navigation. Arrows on the left and right show when there are more items in the current menu level, while a straight bar indicates you are at the end of the list, and pressing the next button will take you up a level.
As well, for each of the 13 categories there is a small preview line showing some of the key settings and real-time input signals for that category.
Preview line shows current units (mi/km), current wheel size (in inches), #Poles, and the state of the speed sensor input (up arrow = 5V, down arrow = 0V)
Preview line shows nominal voltage and chemistry of selected battery pack.
SETUP THROT IN
Preview line shows measured voltage of throttle input, the equivalent % throttle that this voltage corresponds to, and the throttle mode (amps, speed, pass-thru etc.)
SETUP THROT OUT
Preview line shows the current output throttle range, whether it is in Volts or mS pulse width, and has a crude graphical indicator of the throttle ramp rate.
SETUP SPEED LIMS
Preview Line shows the speed limit of the selected preset.
SETUP POWER LIMS
Preview Line shows the amps limit and watts limit of the selected preset.
SETUP PAS SENSOR
Preview line shows # of PAS poles, the state of both the PAS and DIR digital inputs (up arrow is 5V, down arrow is 0V), and the current PAS assist mode.
SETUP TRQ SENSOR
Preview line shows the measured voltage from the torque sensor signal. If the torque sensor is enabled, then it also shows the corresponding calculated N-m of torque on the cranks.
SETUP TEMP SENSR
Preview line shows the measured voltage from the temperature sensor pad as well as the corresponding temperature in degrees if a temperature scaling is enabled.
SETUP AUX POT
Preview line shows measured voltage of auxiliary potentiometer input, the equivalent % full scale limit that this voltage corresponds to, and the limit value that is being scaled (amps, speed, watts etc.)
Preview line shows the programmed value for RShunt in mOhms.
Preview line shows number of mode presets (1, 2, or 3), and number of batteries (1 or 2) which are enabled. In use, you can change between the presets by pressing both buttons, right first to change the battery, and left first to change the mode.
There is no preview line info in the final “Setup Preferences” setup group.
