If i energize Coil #1 what happens?

• The plunger in coli will go down. Block out the fluid on the left. Slider will go to the left. Hydraulic fluid will go to cylinder block #1

• The plunger in coli will go up. Block out the fluid on the right. Slider will go to the right. Hydraulic fluid will go to cylinder block #2

• The plunger in coli will go down. Block out the fluid on the left. Slider will go to the left. Hydraulic fluid will go to cylinder block #2

• The plunger in coli will go up. Block out the fluid on the Right. Slider will go to the Right. Hydraulic fluid will go to cylinder block #1

What is the path for current for the selector when the arresting gear hook is down and the control handle is moved to the up position?

• control switch conacts 5 and 6 close while hoook up

  limit switch contacts 5 and 6 are closed, allowing current flow from ground thru

• control switch conacts 6 and 5 close while hoook up

  limit switch contacts 4 and 6 are closed, allowing current flow from ground thru

• control switch conacts 5 and 6 close while hoook up

  handle switch contacts 5 and 6 are closed, allowing current flow from ground thru

• control switch conacts 5 and 3 close while hoook up

  limit switch contacts 5 and 4 are closed, allowing current flow from ground thru
