Hazardous Material Loader Control System


Description
AeroSpec's UL listed Controls Department is capable of designing systems for the harshest environments.  The control system hardware comprises a purged main control panel, a purged pneumatic solenoid enclosure, purged servomotors and a purged operator interface enclosure.  The electrical hardware is rated for a Class II, Division 2 hazardous location and “UL” listed or recognized, wherever possible, to meet “UL” compliance and to ensure the selection of quality, tested electrical components.  Selected electrical components will be standard off-the-self components where ever possible, to ensure technical support, maintenance, and replacement availability.  Backed by AeroSpec's reputation and 24 Hour, 7 Day warranty, you can feel confident that hazardous material handling will be reliable and safe.

Details
The purged NEMA 4 operator interface panel, located on your machine provides convenient access to the system controls.  The operator panel typically includes the following pushbuttons and indicators: power on, emergency stop, reset, start/stop, auto/manual mode select, step machine, and fault indication light.  A text display provides set point modification and fault messages.

The main control panel will typically contain a 10-slot rack, a rack power supply, all control circuit breakers and fuses, control relays, intrinsic barriers and terminals.  A wall mounted NEMA 4 control enclosure with a door-mounted rotary disconnect houses the controls hardware.  The control panel mounts to the side of the machine.  All field device wiring terminates to terminals in this panel.   Emergency Stop buttons, incorporated into the Control Panel door and the operator interface, remove control power from motion causing devices.  The purged main control panel will be designed and fabricated to comply with Underwriter’s Laboratories and NEC specifications. 

A purged NEMA 4 pneumatic panel normally houses the solenoid valves and an electrically operated air dump.  All pneumatic tubing exits the pneumatic panel through bulkhead connections in the bottom of the panel.  The shut-off, filter and regulator, protected by a Plexiglas cover, mount to the machine base.  A ˝” Q.D. connector provides a system air hookup point.
