Rotary Trim Modules

Rotary Trim Modules are used to trim functions within ESP based on switch position (e.g Boost Control).

Rotary Trim Module Input

Select an appropriate input to use for the rotary trim module. An AVI (Analogue Voltage Input) or SPI (Synchronised Pulsed Input) should be used.

Connection Type

AVI

An AVI (Analogue Voltage Input) is suggested.

Pull up

Enables a 1k pull up resistor to 5V.

This setting MUST be set to Disabled for a Rotary Trim Module.

SPI

An SPI (Synchronised Pulsed Input) can be used where there are no available AVIs.

Sensor Type

Set to Hall Effect for all analogue inputs

Pull up

Enables a weak 10k pull up resistor to 5V.

This setting MUST be set to Disabled for a Rotary Trim Module.

Calibration Tab

This allows calibrations for each switch position on the rotary trim module to be loaded or saved. A calibration comes pre-installed with the ESP Software package, however custom calibrations can be created.

From the image below:

*1 – Selecting this yellow Open icon will allow the loading of a pre-configured calibration file.

*2 – Selecting this blue Disk icon will allow the saving of your custom calibration file.
