BOOM CONTROL VALVE TYPE
Default = 2 Way
1. While the Boom Control Valve Type step, the symbol will be flashing at the top of the display. The
programmable information (2 Way or 3 Way) will be displayed at the left in the console display.
2. This programming step is used to distinguish the type of on-off boom control valves you have on your
system. There are two types of valves that can be used, 2-way control valves or 3-way control valves.
3. A 2-way control valve is simply an on/off valve. Flow is either directed to the boom section(s) or it is
blocked or diverted away from the booms. A 3-way control valve is known as a bypass valve. Flow
continuously passes through this valve. When the valve is activated (on), flow is directed to the boom
section(s). When the valve is not activated (off), flow is directed through a bypass port, back to the
supply tank.
4. If you are using the 3-way type of boom control valves in your system, change the valve using the or
keys. Depress the key to accept the value and advance to the next programming step.
5. If the default value is correct, depress the key to accept the value and advance to the next program-
ming step.
If using 3-way, bypass boom control valves, refer to the instruction manual of the valve
you are using for proper calibration instructions.
