Connecting The Recorder; Connecting The Temperature Sensors; Connecting The Status Inputs; Connecting The Power Supply - Seven Telematics Transcan Advance Install Manual

3.3 Positioning the T Version Cont.
Fasten the recorder enclosure to the surface of the vehicle using the
fixing plugs, screws and washers supplied. Ensure that the fixing plugs
are fitted flush with the mounting surface so that vibration of the
enclosure is minimised. Excessive vibration may cause damage to the
enclosure. The maximum recommended hole size for the fixing plugs
is 11mm diameter.

3.4 Connecting the Recorder

All connections to the recorder are via connectors at the rear of the
instrument (see figure 3.2 for details). For ease of maintenance make
sure that enough slack wiring is left so that the recorder may be
withdrawn from its housing with the connections intact.

3.4.1 Connecting the Temperature Sensors

The temperature sensors are connected to CON 1, marked
Temperature Sensor Inputs 1 to 8. The sensors are precision
thermistors and the polarity of these connections is unimportant.
Each sensor terminates in two wires and up to 4 sensors per block
may be connected. As indicated by the label at the rear of the
instrument. The screen for each probe must be connected to the
recorder chassis using the clamp provided.
In the event of the sensors being connected using a multicore cable
the even numbered pins (i.e. pins 2, 4, 6 and 8) are common and
connected together within the recorder.

3.4.2 Connecting the Status Inputs

The Transcan monitors status inputs as ON/OFF switches. Status
inputs are connected to CON2, marked Status (On/Off) Inputs, 1 to 8
as shown in figure 3.2.
In the event of the status detectors being connected using a multicore
cable the odd numbered pins (i.e. pins 1, 3, 5 and 7) are common
within the recorder.

3.4.3 Connecting the Power Supply

The 3-pin connector CON3 is used to connect the power and provide
connection for the alarm output. The power is connected to pins +
and – with the positive supply on pin 1(bell icon). The supply may be
at any voltage between 9V and 36V DC.
The power supply cable used for installation should be 16/0.2
multicore with PVC outer sheath.

3.4.4 Connecting an External Alarm Device

Pin 3 of connector CON3 is used for the alarm signal. To use this
facility connect an external alarm device (e.g. beacon) between the
vehicle positive supply and this input. When an alarm occurs this input
is connected to zero volts and will switch a current of up to 1 amp.

3.4.5 Connecting a Humidity Sensor [Optional]

Displays the reading from the humidity probe. To install it use CON 4
as described below:
1 – Red colour
2 – Green colour
3 – Yellow colour
4 – Blue colour
We recommend fitting the humidity sensor on a flat surface and
avoiding contact with water.
