Advanced Lightning Protection (ALP)
The OptimizIR includes passive circuitry to protect the controller antenna interface against
lightning or static. When ALP is activated, relays open to electrically disconnect the
stepper motor driver circuits from the antenna. The protection is ready as soon as
controller is powered up. This option does not 100% guarantee controller is protected.
However, the added circuitry greatly reduces the probability of damaging a driver chip.
Driver Chip Replacement
If a driver chip fails, they are readily available from SteppIR at www.steppir.com.
