Crompton Controls

Crompton Modules To ensure compliance with the PUWER 98 regulations, machines such as woodworking equipment must be fitted with a suitable automatic braking device, which ensures the tool stops moving within 10 seconds They must be fitted to new and current equipment Fitting of a brake module is easy, with minimum of disruption to existing wiring when retro-fitting 3 phase Adjustable dc injection time 0.5-25s Integral DOL starter IP55 protection rating Note These types of units are suitable for applications requiring compliance with PUWER 98. DC Brake Modules A powerbrake unit is used where fast, efficient and predictable stopping of a machine in the shortest possible time is required. Using the d.c. injection method, it provides a controlled deceleration to a stop, by injecting a d.c. current into two of the motor terminals and neutralising the rotating magnetic field in the motor after the 3 phase supply has been disconnected. This stops the motor coasting to a halt and reduces the delay time by this enforced braking. They can be used with a standard 3 phase induction motor. The unit may be located on a piece of machinery or adjacent to it, with little disruption or modification required to the existing wiring. The Powerbrake units provide a simple cost-effective solution to motor braking, which is maintenance and wear-free.,Brake Module - For a brake unit, all the control wiring has to be supplied and installed by the customer, including interlocked contactors and pushbuttons.,Production Brakes - Enclosed brakes with all control wiring included, optional DOL starter built in Injects DC on EVERY stop.,Critical Brake - Enclosed brake with contactors built in. Must be used with existing starter, also AC must pass through the unit so that it can be isolated before DC is injected. Only injects DC when E-stop activated.

EL-FI Shaft Power Monitors The EL-FI M20 supervises induction motor driven equipment and provides alarms when abnormal loads are detected. The EL-FI M20's ability to provide reliable monitoring and protection ensures production equipment is optimised and expensive breakdowns and interruptions are minimised. Due to the special method of subtracting motor power losses, the monitor is able to accurately measure the shaft power supplied by the motor to the application. This advanced technique allows the EL-FI M20 to monitor the application load only as opposed to the total motor load, which includes varying motor losses.,Typical applications include monitoring pumps: centrifugal, impeller, screw, magnetically driven, submersible, lobe motor, peristaltic and membrane types. Also suitable for monitoring tool failure on machine tools, mixer protection, jamming material of free-running conveyors, automatic doors, blocked screw feeds,etc. For motors up to 999A 100-690Vac (single & three phase) The motor is used as the sensor Unique algorithm for calculating motor power losses One Touch Auto Set (hassle-free commissioning) Four alarm levels: Max and Min Main Alarm; Max and Min Pre-Alarm Analogue output with P-span/scaling (0-20, 4-20, 20-0 or 20-4mA) Digital input for external Auto Set, Reset or Blocking Alarm Fully programmable with LCD screen Readout in true figures i.e. 5kW, Amps etc Compact size - 90 x 45 x 115mm Easy 35mm DIN rail mounting IP20 Approvals CE, cUL (UL and CSA up to 600V)
