We are swapping out from the XA2 to the XC43 and we originally thought we were going to be using the PWM HS output so we attached a ark suppressing diode on the 4-way 3-pos cart valve (HSP 10-47CB-0-v-24ER). We however ended up using the PWM HS-LS output which has a internal free wheeling diode. Is the newly installed ark suppression diode going to case problems down the road. and is it best practice to just use the internal diode on the PWM HS+LS output?
