5.7 HOW TO CHANGE A PARAMETER
To change a parameter value operates as follows:
1.
Enter the Programming mode
2.
Select the required parameter.
3.
Press the "SET" key to display its value.
4.
Use "UP" or "DOWN" to change its value.
5.
Press "SET" to store the new value and move to the following parameter.
TO EXIT: Press SET + UP or wait 15s without pressing a key.

8. INSTALLATION AND MOUNTING
Instrument XT130C and XT131C shall be mounted on vertical
panel, in a 29x71 mm hole, and fixed using the special brackets
supplied.
To obtain an IP65 protection grade use the front panel rubber
gasket (mod. RG-C). Instruments XT130D, XT131D, shall be
mounted on an omega DIN rail .
The temperature range allowed for correct operation is 060 °C.
Avoid places subject to strong vibrations, corrosive gases,
excessive dirt or humidity. The same recommendations apply to
probes. Let air circulate by the cooling holes.
9. ELECTRICAL CONNECTIONS
The instruments are provided with screw terminal block to connect cables with a cross section up
to 2,5 mm
. Before connecting cables make sure the power supply complies with the instrument's
2
requirements. Separate the input connection cables from the power supply cables, from the
outputs and the power connections. Do not exceed the maximum current allowed on each relay, in
case of heavier loads use a suitable external relay.
10. SERIAL CONNECTIONS
All models can be connected to the monitoring and supervising system XJ500 using the serial
port. The external XJ485 serial module to interface the instrument with the monitoring and
supervising system XJ500 is required.
The standard ModBus RTU protocol it is used.
NOTE: XT130C or XT131C instruments with current or voltage input and 230V or 115V
supply, cannot be connected to the XJ485 serial module.
