The following descriptive writing is the base design criteria for Triad press brake control systems. The inherent design features are superb for enhancing production and safety. Please note that various production options are available within each individual system or package to aid in production.

Design Criteria
Complete self-checking dual logic microprocessor based press brake control with two independent running control channels and a comparison circuit. The comparison circuit assures that both channels agree as the press brake control sequence occurs. The preprogrammed dedicated inelastic control system prevents in field alterations by maintenance personnel to alter or jump out the inherent safety features of the control. The control incorporates a control reliable diverse redundant design concept to assure a higher level of safety and reliability.

Control Reliability "Control Component Failure"
The Triad Press Brake Control meets or exceeds all OSHA 1910.217 and ANSI Bll.1-2001 standards for control reliability. Control reliability standards require that clutch/ brake circuits be designed and constructed so that a single failure or fault within the system does not prevent the normal stopping action from being applied to the press when required, or does not create an unintended stroking action, but does prevent initiation of a successive stroke until the failure is corrected.

Diverse Redundant Design Concept
The Press Brake Control system utilizes the diverse redundant design concept. This gives the clutch/brake control system a higher level of redundancy and control reliability. The two microprocessors or parallel programs are run and made up from different instruction sets written by different programmers. This high degree of safety and reliability of design is the same concept incorporated in our safety light curtains.

Quickview Diagnostic Message Display
Standard on the solid state Triad Press Brake Control System is the revolutionary "Quickview Diagnostic Message Display" Mounted with the operator controls at customer designated location on the control panel, the bright red LED alpha-numeric scrolling message display informs the user of any faults, failures and the current operating status of the control system. The messages are in plain English and will give the press operator and front line supervisor information quickly and safely. The "Quickview Diagnostic Message Display" system is so advanced that it will immediately inform the user of such problems as pressure switch faults, failed output relays, or rotary cam mis-adjustment. The system will also pinpoint internal printed circuit board faults for immediate replacement. This self-diagnostic feature will save many maintenance dollars and will enhance machine uptime measurably due to the units captive troubleshooting ability. Best of all, this information is supplied without even opening the control panel door. Additionally, a complete series of LED's (light emitting diodes) are mounted on the clutch/brake module for visual status of all inputs and outputs related to the machine cycle status.

System Logic and Component Diagnostics
A combination of LED's and alpha-numeric plain English message display will enhance in-field troubleshooting greatly. The advanced design can even troubleshoot itself and advise the user if a printed circuit board is defective and if it needs to be replaced or repaired. Diagnostics are for both the control system logic and for press brake component monitoring. Twenty-nine different messages can appear on the message display.

Redundant Captive Contact Safety Relays
Redundant relays assure safety if an output relay should fail. The system utilizes safety relays which have force-guided contacts. This is a configuration where the contacts are mechanically locked together so that if one set of contacts weld, the other contacts cannot change state. If one should fail, the message display will identify which relay has faulted and what state the relay should be in (on/off).

Triad Solid State Press Brake Controls
Incorporates "cross checking, self-checking and diverse redundancy" to assure an ultrasafe design.

Interrupted Stroke Provisions with Indicator
If the press brake is in the "single stroke" or "continuous" mode and the press stops before the completion of a full stroke, the Interrupted Stroke Provision is activated. The control will automatically switch to the "inch" mode and the palm buttons must be used to return the ram to the top of the stroke. When back at the top, the control automatically switches back to the original operational mode setting and the operator may resume normal production. The Interrupted Stroke Provision improves productivity and safety significantly by eliminating the need for the operator to make mode selection adjustments on interrupted strokes.

Micro-Inch (optional)
Controlled by keyed selector switch on/off on the control panel, Micro-inch provides ram movement for a predetermined amount of time. Micro-inch is actuated by the palm buttons and the amount of ram movement is controlled by a Micro-Inch timer inside the control panel. Micro-Inch also indexes the ram in increments that eases set-up in high speed or short stroke press operations.

Automatic External Trip (optional)
Controlled by a keyed selector switch on/off on the control panel. This option enables a press brake to be cycled by a signal from a robot or feeding device one stroke at a time.
