Ethos 2 Modular Serial System Installation Sheet
INTRODUCTION
This Manual is to be read in conjunction with Ethos 2 Quick Start Manual (TVL350) It is important that you familiarise yourself with both manuals before commencing any work with the Ethos or the
Ethos 2 serial system. Be aware that the lift panel will contain equipment that is supplied with potentially lethal voltages. Please make sure the panel is isolated before carrying out any installation work
or modifications. The TVC Ethos 2 Serial System is a distributed field-bus network for interfacing calls and I/O to an Ethos 2 lift controller. The system is used in place of normal discrete wiring for calls and car
related input and outputs. Instead of each push and call lamp being directly connected to the panel, in the motor room, they are can be connected to local PCB's or nodes that are distributed about the car and lift
shaft. This will depend on particular installation requirements.
FAULT FINDING PROCEDURES
Fault Finding Within a System
With power applied to the system check that all nodes have their green LED’s flashing. If the green LED’s
are not flashing check the power supply on the power feed board.
Check solutions screen and active events in the Ethos 2 for any relevant problems
A network failing to respond on power up would be caused by :
Incorrect or broken wiring connection on the network.
No nodes connected to the network.
One or both of the network power supplies not working or connected.
None of the nodes configured correctly.
If a network has failed to respond to commands sent out by the Ethos 2 then repeated tries will be made
to establish communication. When the network connection is established this is also reported as an event
in the Ethos 2 event log.
System checks
After testing an installation as described above and having no response to calls placed in the system the
following need to be checked:
That the panel is on normal mode.
The DIL switches are set correctly on all boards and termination boards and termination DIL
switches are fitted where necessary.
All network connections are connected to the correct terminals.
Both networks are connected to the panel connections. (If landing network fitted)
The car and landing networks are not swapped over. (If landing network fitted)
Check that the green LEDs' on both Car and Landing nodes are flashing
Check nodes for red fault LED’s. see relevant board installation sheet for description.
If the green LEDs' fail to illuminate then the 24 volt supply is not connected to the node
Check e ternal feeds to the car boards
If all of the above are correct then the networks should function correctly.
EMC GUIDELINES
It is e tremely important that the following guidelines are adhered to.
All bus runs must be kept away from motor wiring, a separation of at least 300mm.
Keep bus wiring away from mains.
If wiring has to cross any high voltage cable this must be done at right angles.
Nodes must be mounted away from any high voltage equipment e.g. motors, door gear etc.
Mains power input and motor output cables should be shielded and earthed as per panel drawings.
Any screens in the trailing cable must be earthed at the panel end only.
Networks must be correctly terminated, with termination board on the landing network and with
termination DIP’s on the last car board in the system.
BASIC SETUP GUIDE
This basic guide is designed to give an outline of installation and set up of a Ethos 2 serial system. Please
refer to relevant installation sheets for more in depth information.
Machine Room
Install main panel. Make sure the routing of any mains or motor cables are kept away from the network
cables.
Connect the car network from the trailer to terminals as shown on the panel drawings. Make sure screens
from the trailer are earthed, as the drawings show.
If fitted connect up the shaft network to the power feed board and then if applicable connect this to the other
controllers in the group.
Once wiring has been completed and checked follow the standard Ethos 2 power up routine.
Make sure all nodes are present in the view I/O screens of the MMI. All nodes can be tested by activating
inputs or call pushes and seeing the result appear on the MMI view I/O screens.
Lift Car
The car related boards may be mounted in the car push station or in the terminal bo on the car top.
Wire in all car pushes and acceptance lamps plus optional features inputs and outputs as per wiring
diagrams.
Configure car module for front or rear operation. Configure the call e pansion boards and I/O boards as
shown on the controller diagrams.
Connect all nodes together with supplied patch cables, as per the drawings. The final board in the chain
should have its network termination DIP’s switched on, again make sure these are only active on one node
on the car / panel network.
Plug the first board on the car top into the relevant trailer connections.
The screens from the trailer cores must be earthed at the panel end of the trailer only, as per the diagrams.
Lift Shaft
Mount optional Landing Nodes in the shaft, either in the push back bo es or in a suitable plastic bo
mounted close to the push station.
Each Landing node has a unique ID this should be set as per the controller drawings, make sure the nodes
are installed at the correct landings.
Connect Landing pushes and acceptance lamps to nodes, make sure wiring is correct 3-wire system.
Connect each landing node to the ne t one in the shaft, using the supplied patch cables.
Connect terminator boards, if applicable, to the ends of the landing networks. Warning: a ma imum of 2
terminators should be fitted to this network in total.
Connect landing node network back to the Power Feed Board on the Ethos 2 controller.
If the optional landing network is not fitted provision for wiring landing calls will be made within the panel on
call e pansion modules.
