Dear Sir,

I am sorry, cause your puzzlement!

I hope at first that you can check several things
1. Please confirm that each valve export the air normally (V1~V5).
*First of all, please input the pressure in 120 PSI range , and confirm that screen " GSF " stops blinking pattern.

2. Please confirm that your air line connect all devices to arrange correctly.
V1-(Gear out) / V2-(Gear in) / V3-(Door open) / V4-(Door close).

3. Please check your equipment, " Gear & Door Air Cylinder " leaks the air.
*Abnormal gear or door device , will influence normal movements of the valve.

4. Please notice the valve surface light change V1~V4. (in mode 2)
*(mode 2) The normal change light is as follows :
On power → V2-(Gear in) & V4-(Door close).
Press " MANU" button → V4 Jump V3-(Door open) → V2 Jump V1-(Gear out) → V3 Jump V4-(Door close)

5. Reverse your gear & door valve at the same time, can keep gear out in no power.

PS. My English not fine, I am sorry !
