Installation
The VLCD5 can be mounted to your recumbent bicycle or trike using the Trike Accessory Mount
which can be downloaded from Thingiverse for 3D printing here: .Trike Accessory Mount
For an standard bicycle, the VLCD5 can be mounted on the handlebars as shown.
The remote button panel should be mounted on the handlebar near the brake lever on either the
left or the right side. All fittings use metric Allen keys

Cable Connections
There are 2 models of TSDZ2:
1. 8 pin model – for use with throttle and brake sensors.
2. 6 pin model – for use with torque sensing motor – no throttle or brake sensors needed.
The following section covers the 6 pin model.
There are 2 weather resistant cable connections from the VLCD5 display:
The long 6 pin cable connects directly to the motor. The motor controller is contained inside the
motor housing and a short cable with a matching connector emerges from the housing.
The connector profile has a flat side to ensure correct orientation, there are also arrows on each
connector which should be aligned.
The connectors are a snug fit to resist water ingress. It is often necessary to make a slight rotating
motion with each hand as you press the connectors together to ensure they are fully engaged.
The short 5 pin cable connects to the remote button panel connector. The process of making the
connection is similar in each case.
For a recumbent bike or trike, an 5 pin extension cable will be required.

Wheel Speed Magnetic Sensor
The VLCD5 uses a magnetic pickup and a spoke mounted magnet to determine wheel revolutions.
This combined with the wheel diameter allows calculation and display of current speed. The
magnetic pickup is also used for calculating distance travelled.
The magnetic pickup is mounted to the cycle frame and the spoke magnet passes the pickup in
close proximity on each rotation of the wheel.
Around 5 to 10mm between the pickup and the magnet is ideal but care should be taken to ensure
there is no physical contact between them at any steering position or under any braking conditions.
The pickup has an arrow to indicate the correct passing point for the magnet.
The magnetic pickup yellow connector should be connected to the short cable from the motor
housing that has a yellow band at the base of the connector. (There is only one cable from the
motor that has this yellow band).
If you have the optional Y splitter connector as shown in the image: The second yellow plug can
be used to allow remote control of 6 Volt external lights. Both plugs on the Y splitter have the
same pinouts and either plug can be used for the motor housing yellow band connector or the 6
Volt external lights. Lighting cable is shown below.
