Rope magnetic encoder

(v 1.0)

To check and download all versions of this guide, go at the following link.

The new DMG magnetic encoder uses a sensor to detect the rotation and position of a magnet placed on the encoder pulley axle. The pulses generated are received and processed by the lift control panel which calculates the position, direction and speed of the car.

Safety and usage cautions

Before installing our products, we recommend you to consult the section about safety and usage cautions at the link below.

Installation

Advice and warnings

The pulley embedding the Encoder must be installed in the top of the shaft or in the pit, close to the machine room.

System components

A) – It is the Encoder pulley that contains the electronic card. It can have 2 resolutions:
– 1.25 mm (100 PPR): To be used with the Pitagora 4.0 controller starting from firmware version AAA
– 2.5 mm (50 PPR): To be used with the V3 / Musa / Pitagora 4.0 controllers up to Firmware Y version
C) – The spring tensioner can also be mounted on the top of cabin as needed.

Mounting

Mounting depends on the type of elevator car.

Type 1)

C) – The spring tensioner can also be mounted on the top of cabin as needed.

Remove the retainer only after the installation is complete.

Type 2)

C) – The spring tensioner can also be mounted on the top of cabin as needed.

Remove the retainer only after the installation is complete.

Wirings

Connection with Pitagora 4.0 system on new installations

A) – Encoder with 1.25 mm resolution

Connection with CRONOS system on new installations

A) – Encoder with 2.50 mm resolution

Connection with PLAYBOARD V3 system on new installations

A) – Encoder with 2.50 mm resolution

Connection on existing installations

You can replace the existing rope encoder with the new magnetic encoder (2,50 mm resolution). Just leave the existing cable (A) and connect it to the new encoder by means of an adapter cable (B).

Diagnostics LED

POWER: If the LED is on, the encoder is powered.
A/B: Status of encoder outputs. With the lift car stationary there is no change in the status of these LEDs (they can be both ON and OFF); with the lift car in motion the LEDs will both be ON.
