Appendix F
Performing the Learn / Teach Function on MC100-1
On extremely rare occasions the VP1000-5 may be running at low or high speed when neither dispenser side is
authorized. This may be due to a leaking incoming signal voltage. A technician can perform the following learn / teach
function to try to correct this.
1. Remove the white reset plug from the MC100-1. No lights should be illuminated on the MC100-1.
2. Insert a jumper wire between the TEACH and JUMPER terminals to create a short.
3. With the jumper wire in place, re-insert the white reset plug. The yellow power light should now be illuminated.
4. Authorize a nozzle on Side A of the dispenser. The green light associated with OUTPUT 1 should be illuminated.
5. Remove the jumper wire. The VP1000-5 should be running at low speed. Hang up the nozzle to de-energize the
dispenser. Seconds later the VP1000-5 should turn off. The VP1000-5 should not be running and neither green
OUTPUT light should be illuminated.
Use extreme care and caution when performing the functions below. Up to 110 VAC is present
creating a risk of electrical shock.
