Integrated Machine Safety Controls
Modernize Legacy Machines
Intrinsic or HazLoc Safety Systems
Safety enclosures for Class/Div rated areas focused on arc/spark exposed to ignition sources requiring low voltage safety switches routing with blue wiring and IMC conduit to safe zones thru safety barriers and relays in NEMA 7/9 enclosures.
Speed Monitoring Safety System
When looking to provide a safe stop condition on a legacy machine without any braking mechanisms, a safety end coder based zero-speed feedback system can be used to monitor machine mechanical state controlling operator accessibility in conjunction with a door locking safety system.
Vertical Safety Doors
Space-saving, vertical door preventing a pinch point, actuating a double acting cylinder using a PO check valve to minimize gravitational drift using 2-hand controls. Rod locks, proximity sensors, and safety valves can be added.
2-Hand Controls
Our Allen-Bradley opti-button 2-hand control system comes with an anti-tie down relay tying both buttons together creating a single-cycle safety circuit. Whether you need required spacing or height, we can supply the system with a bracket only or with a pedestal.
Fluid Power Safety Systems
Pneumatic Safety Controls
Compressed air is one of the three main types of stored energies to be mitigated for risk reduction found in unplanned startups or movement. With pneumatic safety, which is done by monitoring and controlling the energy for the application, safety valves should be used. These valves would provide dual-monitoring of air-operated cam/roller switches for synchronized timing and can be a safe exhaust with or without soft start, safe return, or safe control & load holding. Ross Controls valves can easily be integrated into your system for proper energy isolation along with a proper lockout valve in conjunction with your air prep components such as filter and regulator to create a full air entry set up.
Hydraulic Safety Controls
A common energy source to be controlled or isolated is hydraulics by controlling a mechanical function operated by a force of pressurized liquid. The ability to control pumps, motors, cylinders, and other moving parts can reduce potential hazards such as cutting and crushing hazards, as well as thrown objects. These valves can be a block & bleed or exhaust, a block & hold or stop, a block & return, or block & reduce speed or dual block & stop. Monitoring and controlling this environment should be done with Ross brand hydraulic safety valves.
Emergency Stop Devices
Pushbutton and Pull Cords
Wired emergency stop devices in single or dual channel configuration, such as push button with boxes, push buttons integrated into control panels, and emergency rope pull devices (ISO 13850), all with the required labeling and hardware to provide the required quick stop action to a machine function.
Wireless E-Stop Controls
Use a wireless emergency stop when moving in a long run where e-stop buttons are too far away. These safety-rated devices hop frequencies to avoid bandwidth interference while communicating with a control module located in our enclosure.
Grip Enabling Switch
A handheld joystick, also known as a dead man switch, used for a machine operator to bypass the machine safety functions allowing them to perform a machine function at a jog or safe speed, which are required in continuous run to make adjustments or quality check materials. If the machine poses an issue or concern or an operator becomes injured in the process, releasing the switch will emergency stop the machine showing an open circuit for added protection.
Press Safety Systems
Press Safety Light Curtain System
Protech Systems brand solution uses a point of operation and area guarding devices providing protection on presses with manual or automated processes, which may be require control systems upgrades as part of the package. These systems are used in conjunction with physical machine guards, and safety laser scanners. Upgrades may also include die blocks, power cutoffs, and wedges for optimal protection of your presses.
Press Die Blocks with Safety Interlocks
Power series die blocks, or ram blocks used to support a die from overhead creating a crushing hazard through unexpecting drifting or falling. These devices cover a range from 35 to 125-ton static load, adjustable from heights of 9" to 36", to include safety interlock connection to ensure die block is being used during setup or maintenance.
Non-Safety Rated Support Devices
CNC Port Spin Window
Improve visibility of your machining environment which include milling machines and lathes through self-cleaning by removing or slinging coolant and chips from a viewing area of your access door, boosting productivity, and reducing machine downtime in the process.
Camera Monitoring System
Visual protection can be added as an administrative control resource by removing operators from machine hazards by replacing their eyes with a closed-loop camera and monitor to view machining operations.
