Machine Safety Equipment

Safe Switching and Monitoring

An extraordinary extensive range of safety-related switchgears for the position monitoring of guard doors and the non-contact protection of hazardous zones and danger points, as well as safety switching appliances for special applications.

Guard Door Monitoring Products:

• Safety switch with separate actuator
• Solenoid interlock
• Pull-wire emergency stop switches
• Electronic safety sensors

Norman Equipment is a proud distributor of the Schmersal range of active optoelectronic devices (AOPD) to provide non-separating safeguarding of hazardous areas, ranging from point of operation to danger zone or perimiter guarding. These "virtual safety guards" are available as safety light barriers, safety light grids, & safety light curtains.

The control devices manufactured by Schmersal always ensure a safe and reliable transmission of the operator's commands. These devices have a long life and an intelligent ergonomic construction. Products include but are not limited to:

• Pull-wire emergency-stop switches
• Emergency-stop buttons
• Control panel
• Enabling switches
• Safety foot switches
• Two-hand control panels

When crushing or shearing points are present and need to be safeguarded, such as on elevating platforms, rising stages, sliding doors, or industrial gates, tactile safety devices offer a simple and easy to fit solution. In the hazardous area, two-dimensional safety devices could be useful as well. For example, industrial robots, punching machines, and woodworking machines.

Safety controllers feature redundant, dual channel, cross monitoring logic circuits and are designed to increase the level of safety in machine guarding and/or E-stop control circuits. The circuits continuously check for and detect faults in the system's safety cicuit components and interconnection wiring.

Detecting Safety Circuit Faults

• Welded interlock/E-stop switch contacts
• Open circuits
• Short circuits or ground faults
• Capacitive or inductive interference on controller inputs
• Welded or stuck contacts in the controlled output motor contactor or control relay

Products intended to reduce facility risk and insurance costs while increasing safety for plant employees and surrounding communities. Products include fire safe fusible link assemblies for emergency shutdown, spring return handles to eliminate the risk of leaving a critical valve in the wrong position, and lock-out devices for both automated and manual valves.

In process engineering plants such as refineries with exposed building parts or extensive water management systems, surge events can cause disastrous consequences: from damage or destruction of expensive components and machines to breakdown of complete automation systems-not to mention risks to personnel.

Besides these dangerous risks to people and environment, overvoltages are still one of the most common causes of damage in electrical plant engineering. They primarilty occur due to lightning strikes or switching operations, but also due to the following causes:

• Electrostatic discharge
• Brush fire of large electric machines
• Fluctations in power supply
• Ground faults / short circuits
• Triggering fuses
• Parallel installation of energy and information technology control systems

Pepperl + Fuchs' product range provides you with powerful surge protection solutions for various applications including devices for signal line protection, supply line protection, fieldbus, and wireless solutions.
