Control Room Interface

Pull CableContinuous monitoring from conveyor startup to shutdown identifies problems before they cause stoppage, damage, or personnel injury.

Modular design allows functions and devices to be added or removed to meet your specific needs.

No need for conduit or extra wiring. CTS Pull Cable supplies all the communications for the system, while also functioning as the pull cable. Other systems require individual switches to be hardwired through conduit.

Pinpoints faults by type and location so maintenance crews spend less time searching for the problem, and get vital equipment back online sooner.

Emergency stop, pre-start warning, and speech communications along the entire length of the conveyor enhance employee safety and equipment protection.

Interlocking and sequencing can control material flow. If a safety device stops a downstream conveyor, either upstream conveyors are stopped or flow is diverted to another conveyor. Once the problem is corrected, all conveyors are restarted sequentially, and the conveyor system is once again charged with material.

Central control room provides an overview of your entire operation, combining information from all controllers and field components, using Supervisory Control and Data Acquisition (SCADA) software.

Hardwire or RF radio communications. Controllers can use any industrial protocol or serial communications (RS-32, RS-422, or RS-485). Or, RF radio transmitters can be used to remove the need for hardwire communications.

NEXT BACKConveyor Pull Cord Switches

Emergency stop switches stop the conveyor electrically at any point along the conveyor.

Heavy duty pulling mechanism compensates for temperature drifts, preventing false trips.

Electrical rotary switch allows the switch to be tripped manually. The electrical switch is a self-wiping rotary switch (not a microswitch), and consists of two normally open and two normally closed contacts.

Switch knob is padlockable in the "Off" position. Once the switch has been tripped, the knob latches in the "Off" position and must be manually reset in order to restart the conveyor.

High impact U.V. stabilized polycarbonate enclosure is rated IP 66 and D.I.P. (Dust Ignition Proof) degree of protection.

Recommended distance between switches is 330 feet (100.6 m).

Approved for use in non-hazardous locations by the Pennsylvania Dept. of Environmental Resources Mine Safety and Health Administration (MSHA).

Conveyor Belt Protection:Troughing Belt Misalignment Detector

Troughing belt misalignment is detected by two upright arms, which are connected to an electrical switch by a glass reinforced polycarbonate coupling.

If the belt misaligns on either side to the extent that it could cause damage to the belt or conveyor structure, it contacts one of the upright arms. The arm tilts in the direction of the moving belt and activates the switch.

Adjustable mechanical trip delay on the switch coupling mechanism prevents false trips.

Switch structure is designed to minimize material build-up which could render the switch inoperable.

Conveyor Belt Protection:Doppler Conveyor Belt Speed Unit

Non-contact, high accuracy speed unit has no moving parts so it is maintenance free.

The Doppler Speed Unit uses the latest technology to provide a revolutionary method of monitoring conveyor speed. The unit is equipped with a 2-line LCD display with 4 push buttons. The push buttons are used to configure the unit, and belt

speed is displayed on the LCD with the belt is in motion. Part Number: CTS 7000 DSU

NEXT BACKMain Page

Conveyor Belt Protection:Infrared Conveyor Belt Rip Detector

Part Number: CTS 9000 IRRD

Network of infrared sensors detects material spilled through a rip in the conveyor belt.

The Infrared Rip Detector is an electronic device consisting of a network of infrared sensors mounted beneath the troughing belt. If a foreign object penetrates the belt, material will fall through the cut in the belt onto the detector's tray. As material builds up on the tray, the infrared beams are blocked and the conveyor is stopped. A "wash" cycle allows the unit to be cleaned without stopping the conveyor belt.

Conveyor Belt Protection:Ultrasonic Conveyor Belt Misalignment Detector

Ultrasonic beams detect misalignment with no moving parts.

The Ultrasonic Misalignment Detector has a profiled arm shaped in the same configuration as the troughed section of the belt. Two alignment sensors near its edge each emit a narrow ultrasonic beam towards the belt surface at predetermined

angles. The beams are reflected back to the sensors.

Belt misalignment in either direction causes the reflected signal to be outside the acceptable limit, and the detector will provide a visual indication that misalignment is occurring. If misalignment continues beyond a predefined time limit, the

detector will trip and must be manually reset. Part Number: CTS 7000 RF/BL

NEXT BACKMain Page

Conveyor Belt Protection:Motion Detector

Programmable electronic motion detector displays the speed of any rotating or moving object in meters per second, feet per second, or revolutions per minute (RPM).

An object's movement is detected by a proximity switch connected to the unit, in two different modes:

Static mode monitors for off-speed condition

Dynamic mode monitors for movement, acceleration, and operating speed

A two line LCD and four push buttons are used to set system mode, run speed, trip speed, movement time, acceleration time, and other settings.

Part Number: CTS 700 MD

Conveyor Belt Protection:Blocked Chute Detector

The blocked chute detector is a tilt switch mounted inside the chute to detect any restriction of material flow within a transfer point. Blockage which causes the switch to tilt more than 15° will activate the switch.

The switch consists of 3 normally closed mercury switches connected in series, mounted 120° from each other. A steel enclosure provides optimum protection.
