2.1.5 TERMINATION RESISTOR AND POLARIZATION RESISTOR
• To keep balanced the RS485 the beginning and the end of line must be closed with a resistor
of 120Ω. If XWEB 3000 is placed at the beginning or at the end of the line, please active its
termination resistor by adding a jumper in position 3 (JMP3 on the back side of the unit). DO
NOT add the jumper if XWEB 3000 is placed in the middle of the RS485 line.
• If in the setup there are NOT Dixell’s controllers and you are experiencing communication
problems, please add the polarization resistors by adding a jumper in position 1 and 2 (JMP1
and JMP2 on the back side of the unit).
2.1.6 COMPATIBLE INSTRUMENTS
For a more complete list please read Appendix D.
2.1.6.1 PARTICULAR DEVICE SETUP
• All controllers equipped with 2 serial addresses (XC400/600/800/900, XH200/300/400 etc.) must
be used with both addresses equal.
• iCHILLs need to activate a particular value in the “Advanced” section. User must check “Force
Device On status”. Remember to stop-start acquisition after this operation.
• To use non Dixell, but modBus compatible controllers (such as Energy Analyzer by Carlo
Gavazzi) follow this instructions:
a) Go to “Devices” and choose a controller.
b) Push “Add”. A new controller on the same address will be added.
c) Modify the serial address to match the one of the new controller. Push “Confirm”.
d) Go to “Advanced” and with “Model” menu select the correct model. To complete the previous
example, to insert Energy Analyzer “WM22-DIN-AV5” choose “ENERG.ANAL”.
e) Check “ Force Device On status” and all the other categories needed such as “Device Type”
and “Sampling”. Push “Update”.
2.1.6.2 XEV MANAGEMENT
The XEV driver for the electronic expansion valve On/Off can be linked together with a controller.
a) Enter the programming mode of the XEV and set Mod=AdU
b) Set the Adr to the same value of the controller the XEV is linked to.
c) Make a “device find” on the XWEB3000, only the controllers will be added to the setup. XEV will not
be available during this phase.
d) Enter devices and pick up the first device that has been linked to the XEV. Go to Advanced section
and make a model change according to the following chart:
DEVICE XEV MODEL TO USE
XM463 ver. 0.2 XEV ver.0.3 XM463K+XEV (0.2+0.3)
XM466 ver. 1.2 XEV ver.0.3 XM466+XEV (1.2+0.3)
XR570D ver. 2.0 XEV ver.0.3 XR570D+XEV (2.0+0.3)
