13. Hydraulic Lift Installation Guide
13.1. Introduction
The Ethos Two can be configured to control various hydraulic setups including: Standard hydraulic DOL / Star-Delta.
Soft-Start / ELRV Hydraulic Block and Hydraulic with VF Drive (Bucher ELRV or Algi).
13.2. Step by Step Installation Sequence
The following sequence should be followed when installing the panel and commissioning the lift.
The instructions, which follow, are intended as a guide to site testing and trimming and should be read in their
entirety before proceeding. The commissioning engineer has the sole responsibility for taking adequate safety
precautions during the carrying out of these procedures:
Wiring and General Precautions
Do not connect or disconnect the wiring or connectors whilst the power is on.
If a VF drive is fitted: Do not touch the circuit components after turning off the main
current power until the CHARGE light is extinguished.
The main drive earth terminal PE must be grounded.
Do not connect output terminals U, V, W to the AC mains incoming supply.
Do not conduct high-voltage insulation tests on the regulator. Isolate totally the regulator
if insulation tests are conducted on the panel.
Mains Wiring and Motor Wiring
See Sheets 2, 6 of the wiring diagrams for connection details to hydraulic valves and any VF
regulator fitted
Follow EMC guidelines in the General Installation section.
If a VF drive is fitted pay due diligence to the motor and drive EMC instructions. Due to the RF voltages and currents
generated by the drive causing conducted unwanted radio frequency interference signals which by
inductive/capacitive coupling can get into the supply network. It is important to pay particular attention to the EMC
guidelines.
Preliminary Work
Check all safety circuits and ensure all safety circuits are in order.
Ensure lift doors are closed and remain closed.
Switch to "Emergency Electrical Operation / Panel Test or Car Top Test"
Power Up
Check any external phase sequence inhibits and correct by reversing input phases if required.
(Note the regulator is not input phase sequence conscious). Carry out a check of motor phasing and valve wiring,
ensure these are as per the schematic diagrams.
Rotation Check
Motor direction can usually be changed by swapping motor phases.
Pre Shaft Learn Checks
Using the Profile Screen, confirm the lift moves at the correct speed on inspection control.
Configure any value or drive following the manufacturer’s instructions.
Follow the General Installation Guidelines from here.
