The lift control valve is situated on a hydraulic power unit and activated

by a lift control system.

2.3 General safety instructions

ATTENTION!

Take note of the following instructions before carrying out any

work.

2.3.1 Intended use

The Lift Control Valve has been built in accordance with the state of the

art and recognised safety regulations. Nevertheless, risks to the life and

limb of users or third parties may arise during its use, or damage to the

3 Product description

3.1 Intended use

The iValve intelligent lift control valve is an electronically controlled hy

draulic valve block for controlling hydraulic lifts. The iValve is situated on

the hydraulic power unit and activated by the lift control system. Elec

tronic control is accomplished by an electronic unit – the iCon – that is

housed in the control cabinet. At standstill, the weight of the lift is sup

ported by a check valve integrated in the iValve. In operation, the elec

tronic controller regulates the three states "Bypass", "Travel UP" and

"Travel DOWN", and the transitions between them. In the electronic unit,

this travel is represented in a form known as travel curves. During oper

ation, the travel curves for that particular lift are optimised by the learn

ing algorithm "iTeach". In addition, the valve block includes the following

functions and components: a hand pump with manual emergency lower

ing (with piston-creep prevention), a ball valve, a pressure gauge, a

pressure sensor with up to two pressure switches, speed monitoring, a

temperature sensor, a UCM/A3 valve in accordance with EN 81-2 + A3.

3.1.1 Conformity

The product was designed and developed in conformity with the follow

ing directives and standards:

EC-directive 2006/42/EG

EC-directive 95/16/EG

Standards EN81-2:1998+A3:2009

Safety rules for hydraulic lifts

Standards EN12016:2004+A1:2008

(Electromagnetic compatibility for lifts)

The lift control valve has a stuck-on nameplate with the following infor
