XMT-SI-485, XMT-SI-RF, XMT-SI 4-20mA, BlackSeal rev.09 2017.03 - ENG XMT-SI-RF WITH RISER XMT-SI-485 WITH RISER XMT-SI-485 WITHOUT RISER Please follow the above procedures if probes are wired. The only difference is that the length of the riser must cover the total length of the probe, and a cap with a cable gland must be screwed to allow the exit of the connection cable.
This cable must be connected to the back bone using a junction box. It is recommended to use a junction box IP68 for intrinsically safety connection supplied by Start Italiana under request. In a typical electrical connection all the probes are connected in parallel. Normally all the bus connections must be cascading to grant certain transmission distances.
XMT-SI-485, XMT-SI-RF, XMT-SI 4-20mA, BlackSeal rev.09 2017.03 - ENG XMT-SI-485 HOUSING OPENING AND CLOSURE The TOP and BOTTOM caps can be unscrewed. This is valid for the latest revision of probes. For older revision the fixing caps is different. Take a look at the bottom cap. If you are able to locate the brass screws in the bottom cap then you have to proceed as following: PLEASE PAY ATTENTION NOT TO LOOSE OR DAMAGE ANY OF THE...
XMT-SI-485, XMT-SI-RF, XMT-SI 4-20mA, BlackSeal rev.09 2017.03 - ENG MODEL XMT-SI-RF DIP-SWITCH PROGRAMMATION There are several operation modes that can be selected through the internal DIP-Switch. These operation modes can be applied to RF probes. The operation mode defined will amend the life battery duration. Below is a table which gives the information on the estimated life battery referred to the selected operation mode.

XMT-SI-485, XMT-SI-RF, XMT-SI 4-20mA, BlackSeal rev.09 2017.03 - ENG If the buffer is empty performing command S the probe will not send any answer. This option is available both for new probes and for a retrofit on existing intrinsically safe probes. In this case probes should be returned in factory for adding battery, longer housing and firmware modification.
