Oil/Motor Temperature Control
In the event of the motor overheating, the contact opens and the lift is put out of service.
Blocking of the lift can be immediate or when the call ends, depending on the setting.
Weight Load Control
When COM input is active, floor reservation calls are neither recorded nor managed.
When SUR input is active the elevator car does not start and the acoustic signal in the elevator car is activated. The SUR
signal is ignored while driving.
Position/Speed Control with DMG Encoder
If floor counting is carried out by DMG incremental encoder, position, deceleration and stop are controlled by counting the
pulses coming from the DMG encoder. The counting of the pulses is suitably corrected (reset) by the signals at the top and
bottom (AGB / AGH) and from the signal of the door zone (ISO1).
Elevator car Position/Speed Control with Motor Encoder
This control system can only be used on systems with inverter VVVF with a Gearless Motor.

Location, stop and deceleration are controlled by counting the pulses coming from the encoder of the motor. The counting
of the pulses is suitably corrected (reset) by the reset signals at the top and bottom (AGB / AGH) and from the signal of
door zone (ISO1).
The same J16 input connector is used to connect, with the appropriate cable, the encoder interface card, which is inside
the FUJI inverter.
Parameter ”Count System” should be set as “engine encoder”. In menu choose 2048 number of pulses. Subsequently the
dimensional parameters of the motor pulley and the type of pulling system should be inserted. Next the system asks to set
the shaft length in order to set the correct sensitivity. Only after these steps are completed, Will it be possible to run the
automatic floor levelling procedure.
Door Command
The door command board can command either one or two doors with alternative, selective or passage through opening.
Output and inputs are available on the jst connectors on the TOC board and on APPO board (in the controller).

Input FOB (B door opening limit) closing to GND (NA) I = 5mA
Input FFB (B door closing limit) closing to GND (NA) I = 5mA
Protection Against Electrical Interference
The boards has been designed to be protected against various types of interferences, following standard/normal
requirements according to the requirements of the norm, against accidental mistakes and localization. Never the less we
advise that the following rules are respected:
Connect all metal masses to ground;
Connect all unused conductors to ground (on the side of the cabinet);
Connect the anti-noise filters delivered with the controller (inserted in the spare parts kit) in parallel to the brake coil
(max 230VDC) and as close as possible to it;

When a retiring ramp is present, connect the anti-noise diode delivered with the controller (spare parts kit) in parallel to
the retiring ramp coil and as close as possible to it; make sure to connect the cathode (diode side marked with a white
strip) to the power supply positive common “CAME+” and the anode to the negative “CAME-“;
For the wiring towards the elevator car, if signals and 24V power supply wires are present in the same travelling cable,
make sure these are kept apart (safety chain circuit, doors or retiring ramp power supply, 230V etc.).
For installations with VVVF all the instructions provided by the manufacturer must be fulfilled, regarding both the filters
and the wiring. For a proper operation of the system, it is essential to use a shielded cable for connections to the motor
and to the braking resistor;
Always avoid placing signal cables in the vicinity of the power cables and / or power supply.
Main Connections and Temporary Operations
According to the ”Temporary Operations” page of the electrical wiring diagrams schematic page:
1. Connect the main power supply
2. Connect the traction motor and Brake Resistor or the hydraulic pump motor
3. Connect the brake or valves
4. Connect the Motor temperature sensor or Oil temperature sensor
5. Connect the inspection box for temporary operations (Using the Temporary Cable) connecting them to the terminals
(screw)
6. Switch on main power
7. Carry out the Motor Tuning procedure (traction only) (Annex IV)
8. Install the Electrical System (Quick Start Guide)
Learning Procedure of floors
If the Controller is equipped with Absolute Encoder or DMG Encoder or Motor Encoder it is possible to take advantage of
the floor position learning feature, which allows for a faster system configuration and fine tuning. The procedure is different
according to the type of encoder, as described in following sections:
Normal Service Mode
Once all above procedures are completed, it is possible to put the system into Normal Service mode.
For ride comfort improvements check ANNEX 5.
The system performs a reset run and stops at the lowest floor. If no error occurred, it is possible to manually fine tune the
precision of stop at each floor as indicated in rope and pulley Encoder positioning system or Optical/Magnetic positioning
system.
To facilitate checks and installation start-up, please refer to the menu “Configuration” => “Test” and the Annex II.
Fine tuning of floor stopping accuracy
ELGO LIMAX 33CP: Manual Teach Procedure
DMG Encoder or Motor Encoder: Automatic Learning Procedure of floors

Once the self learning procedure is completed, it is possible to manually fine tune the stopping accuracy at each floor by
using the PLAYPAD programming module, without having to access the shaft.
Regulation of stopping accuracy:
1. Make sure the installation is in the “NORMAL SERVICE” mode
2. Use the PLAYPAD module directly with the controller or remove it and connect it to the TOC board on the top of the
cabin by using the cable (optional).
3. Enter the <Positioning> menu, select “Floor Position” parameter for the floor to be adjusted (use Left / Right keys to
select the desired floor). The value displayed at the bottom of the Playpad screen indicates the current floor position (in
mm) for the selected floor; press [ENTER] to modify.
4. Increase or decrease the indicated position by using UP/DOWN keys on the PLAYPAD module.
5. Press [ENTER] to save the updated value.
6. Check actual stopping accuracy by calling the lift to the selected floor. If needed, repeat steps 3, 4 and 5.
7. Repeat the procedure for every floor
Shaft: Access
Hint: For systems with encoder counting it is possible to activate the access procedure in the shaft without the system
being stopped due to the interruption of the safety chain (opening of the landing doors). It is also helpful in EN81-1
installation.
With the lift in normal operation:
Keep the doors open by keeping the door BRA or BRB button pressed
On the elevator car control panel press the current floor button 3 times.
The panel will emit a continuous sound to warn of the activation of the procedure which temporarily excludes all calls.
(procedure can be deleted by pressing the door open button again)
Exit from the Cabin;
The Controller closes the doors and moves lift 2 meters down with slowdown and standard stop. The technician can
open the doors and easily access the cab roof. If the cabin does not have enough space to descend, it moves upwards
by 2.5 meters (pit access and / or control of the cabin bottom).
If you do not enter the well, the Cabin remains stationary in this condition for a maximum time of 10 seconds before
returning to normal service (new calls are not available in this time).
Access to the shaft for systems compliant with the EN81-20 / EN81-21 standard requires that, after an access and
subsequent exit from the llift shaft by an authorized person, there is a reset procedure that excludes the return to automatic
operation of the lift. Below are the instructions for entering and exiting the shaft in the case of 81-20 or 81-21 systems.
EN81-20 Configuration
Parameter: See Annex X.
Access to the Pit
Is detected by operating the pit stop switch or by switching the pit control panel on to ‘inspection’. (both conditions open the
safety chain on point SE1).

This condition activates the Fault RSP (code 20) and prevents the movement of the elevator car in normal operation
(Movement is now possible only in Inspection mode).
After the end of the Inspection manoeuvre the personnel must:
Return the selector switch and any STOP buttons to ‘Normal’ and exit the shaft of lift.
Close the landing doors (check the safety chain) and carry out the reset using one of the following methods:
From lowest floor with three quick opening / closing of the release key or.
From the panel with three quick presses of button
From the PlayPad with specific reset (RSP reset).
Characteristics of the auxiliary contact on the door (s) at the lowest floor:
Monostable NC contact (does not open during normal door operation).
The auxiliary contact is electrically connected to the BDU’s Door input or to the terminal (screw) of the controller on the
E511 input (NC contacts in series when there are multiple shaft access doors eg. Pit Access Hatch).
No Access the Car roof
No control required for access to the cabin roof.
EN81-21 Installation with door’s Bistable contacts
Headroom and reduced pit (Compliance with Article 2.2 of Annex 1 of Directive 95/16 / EC of the European
Community)
In systems where the minimum required dimensions in the top and bottom of the shaft cannot be guaranteed, according to
the requirements of the regulation EN 81, special alterations must be made to the system and the controller in order to
avert the risk of injury to workers carrying out maintainance work in the shaft.
The following is a relevant section from the regulation:
“The lift must be designed and manufactured in order to prevent the risk of crushing when the elevator car is in an extreme
position. In order to achieve this, a free space or refuge beyond the extreme positions must be provided. However, in
exceptional cases, allowing the Member States the possibility of giving prior approval, particularly in existing buildings, the
competent authorities may provide other appropriate means to avoid this risk, if the previous solution is impossible to
achieve”.
The controller of the lift is able to automatically manage the floor doors opening control in systems with limited space in the
extreme points of the shaft. As indicated schematically in the illustration below, the controller must be equipped with a
control circuit at the top/bottom of the shaft so that, when the maintenance worker opens the landing door to access the
shaft, a contact connected to the dedicated input which provides monitoring of shaft access to the lift controller.
The specific procedure is according to the type of Installation as described in following sections.
The reset procedure is possible only if bistable contacts are open, otherwise the controller checks an automatic reset of
bistable contacts (without any reset procedure): so the controller gives a RSP Fault (Cod 121) and it is necessary to open
the Bistable circuit and after make a reset procedure.
