• Programmable: no hard-wired logic
• Over 50 I/O
• Socketed Relays for safety circuits and special functions
• Easy to Install
• Connects Directly to Head and Handles
• Connects to T3R Controller for overall cut-length solution
• Rugged Construction
• Easy to Use. Built to Last!

Joral Head Control Box
 
HCB System Overview
The Head Control Box (HCB) is a programmable logic device that takes the signals from the handles (or joysticks), the signals from the head/carrier, and the signals from the cut-length controller and performs logical control for the head and carrier valves and functions.

The diagram to the right show how the HCB fits in an overall system.

• Head Control Box Connects to Handles
• Head Control Box Controls Carrier and Head Functions
• Adapter Cables Available to match the Head and Carrier
• Optional T3R Controls the Cut-Length Control
• Optional T3R Provides the User Interface
• Great for Non-Measuring Control Applications
• Use for Retrofits / Restorations / Repairs
Additional Specifications
The Head Control Box can be tailor-fit to meet the needs of the system. 
The following information provides a basis for the system to use as a starting point.

HCB Control Functions
The HCB accepts the buttons from the joystick handles,
the status from the machine,
and the 2-speed valve control signals from the T3R and then controls the valves accordingly.

Using the Head Control Box  With the CLC-T3R
When the T3R is combined with the HCB, the HCB receives all the connections from the joystick handles, the boom, and the carrier.
The signals that the T3R requires are routed through the HCB.
A single cable connects the T3R to the HCB.

Using the Head Control Box Stand-Alone
The HCB can be used stand-alone as a head and carrier control system.
In many cases, it can be enhanced to perform the counting and cut-length control.

HCB General Input/Output Capability
From the view of a general control computer, the HCB has the following I/O:
22 digital inputs
22 digital outputs
4 optional auxiliary function relays
Run input
Safety Interlock input
