Cabling methods and distances determine the best way to ground the shielded cable; at both ends or only at one end. Buffer amplifier pulse output can be measured during driving. If the pulse sequence is not uniform and for instance longer pulses occur every now and then, the reason may be one of following: - an incorrect air gap (proximity switch) - the sensor is not properly on the top of the pulse wheel (proximity switch) - disturbances are transferred to the sensor cable - the pulse wheel is faulty Honeywell 3GT101DC Hall-sensor requires tooth movement past the sensor. A motionless tooth can not generate a pulse. 3.3.4 Buffer amplifier KAE234 The speed sensor (proximity switch or sensor bearing) is connected to inverter via KAE234 buffer amplifier. KAE234 must be located near the sensor (usually in the connection box of the hoist or the motor). Without a buffer amplifier some faulty pulses could activate the speed supervision of inverter. Typically the problem would be a momentary lack of pulses or oscillations at the sensor output. Usually the noise sensitivity increases when the sensor temperature rises.

Voltage range 200...690Vac AC Line Voltage Output voltage U DC Half wave 0.45 x U AC Maximum current 1.25Adc K7 K7 L1-1 L1-2 L2 a K7 K7 b REC12 Brake When the brake is opened, the brake contactor K7 connects two phases of mains voltage to terminals L1 and L2. In addition, the brake contactor shorts terminals a and b thus making the DC-circuit. To close the brake, the brake contactor disconnects the supply to terminals L1 and L2. The released brake contactor also opens the brake coil DC-circuit, which speeds closing of the brake. The purpose of the varistor there is overvoltage protection for K7 contacts and the brake coil. 3.4.2 ESD141 Brake control unit ESD141 is a line voltage full/half-wave rectifier for DC-brakes. Voltage range 200...690Vac AC Line Voltage Output voltage U DC Full wave 0.90 x U AC Half wave 0.45 x U AC K7 K7 Maximum current 1.25Adc continuous and 2.5Adc at ED5% K7 Set 0.3s 3 2 1 4 K7 K7 5 ESD141 6 7 Brake When the brake is opened, the brake contactor K7 connects two phases of mains voltage to terminals 1, 2 and 3, which makes the device a full wave rectifier. The full wave mode is used to get the brake open fast. In addition, the brake contactor shorts terminals 4 and 5 thus making the DC-circuit. 25/79 This document and the information contained herein, is the exclusive property of R&M Materials Handling Inc. and represents a non-public, confidential and proprietary trade secret that may not be reproduced, disclosed to third parties, altered or otherwise employed in any manner whatsoever without the express written consent of R&M Materials Handling Inc.
