Intelligent Lift Control Valve with Electronic Card

Transcription

1 Intelligent Lift Control Valve with Electronic Card Q max = 500 l/min, p max = 80 bar Leak-free, two-stage, electronically controlled, without frequency control i50 and i500 Information lift-control valve No modifications of the travel curve or mechanical adjustments are necessary Constantly short travel times, regardless of loading and temperature Constant levelling accuracy of ± mm, which prevents dangerous tripping accidents Self-monitoring function guarantees fully integrated A conformity (TÜV approved) Pleasant acceleration and slowdown thanks to an electronically controlled travel curve Soft-stop function for smooth approach and entry. The ivalve lift-control valve is an electronically controlled hydraulic valve block for controlling hydraulic lifts. The ivalve is situated on the hydraulic power unit and activated by the lift control system. Electronic control is accomplished by an electronic unit the icon that is housed in the control cabinet. At standstill, the weight of the lift is supported by a check valve integrated in the ivalve. In operation, the electronic controller regulates the states Travel UP and Travel DOWN, and the transitions between these states. In the electronic unit, the travel is represented in a form known as travel curves. During operation, the travel curves for that particular lift are optimised by the learning algorithm iteach. In addition, the valve block includes the following functions and components: a hand pump with manual emergency lowering (with piston-creep prevention), a ball valve, a pressure gauge, a pressure sensor with up to two pressure switches, speed monitoring, a temperature sensor, an emergency stop DOWN valve (UCM/A) in accordance with EN 8..

The electronic control is accomplished by an electronic unit the icon that is housed in the control cabinet. In operation, the electronic controller regulates the states Travel UP and Travel DOWN, and the transitions between these states. In the electronic unit, this travel is represented in a form known as travel curves. During operation, the travel curves for that particular lift are optimised by the learning algorithm "iteach". The ParamCard is a memory card on which the system-specific parameters and data are stored. The ParamCard plugs into the icon. Without the ParamCard being plugged in, no lift travel can be carried out. 00-P EN-0/ /

13 .6 Dummy icon optional.6. The "Dummy icon" can be pre-installed in the control cabinet as a "placeholder" instead of the real icon (control electronics for the ivalve). It has all the plug connectors that the icon has, so that the wiring can also be done in advance (cable lengths and cable positions)..6. How customers contact the test system The central "X" plug offers an additional benefit. All signals that are wired from outside to the icon are available on this plug. Consequently, the wiring can be checked with an automatic test system..7 Accessories Part No Dummy icon Handterminal including connecting cable PC software "iwin", including connecting cable Power supply module i Power supply module i Plug connector kit Solenoid connection cable:.5 metre 6.0 metre metre (for Halogen-free versions, contact Bucher) ibox connection cable:.5 metre 6.0 metre metre Related documents Reference 00-D I I S S Planning information ivalve Commissioning and maintenance ivalve Parametrization and maintenance ivalve Spare parts ivalve / icon i50 Spare parts ivalve / icon i500 info.ch@bucherhydraulics.com 06 by Bucher Hydraulics AG, CH-65 Neuheim All rights reserved.
