페이지 인쇄To test that the temperature sensors are detected and what temperatures are being measured, send a
SMS with the text OWTEMP-SHOW to the data number of the SIM-card mounted in the unit. The unit
will return a SMS with a list of the detected temperature sensors and the measured temperature. If the
returned value is "No sensors defined", the sensor is not responding – check the installation! The
answer can be divided into several SMS if the content of the response contains too many characters.
The responds SMS can look as follows:
283326B30100007C = 27.3
2974E541564B1575 = 7.3

Cable for one-wire sensor
It is very important to use a twisted pair cable when an extension is needed. The cable should
preferably be the same type as the original sensor cable. The cable is with silicone outer jacket and
Teflon inner jackets so it is durable in high and low temperatures. The capacity between wires must
not be higher than 10 – 15 pF per meter. Total length (added) for all sensors is maximum 20 meters.

Where to mount the temperature sensor
Possible places to mount the temperature sensor:
•
At the air intake of the cooling system
•
At the air out of the cooling system
•
On a central place in the compartment
AddSecure recommends that you agree on a mounting place with the customer.
Mounting/fixing the temperature sensor
Take care not to damage the temperature sensor when mounting/fixing it and make sure it is placed
well protected.
The sensor head must be free, i.e. it must not be covered by a bracket, glue, etc.
Sensor ID
Each sensor is labelled with a unique ID No. Enter this ID number and state the mounting place on the
data sheet.
The data sheet must be given to the AddSecure support.
