INSTALLATION
2 OPERATION
The XZR200 is designed as a fi t and forget device. Once con fi gured, installed and all
electrical connections made, there are no further operating instructions required. Only
routine inspection and calibration of the unit is required. The inspection is more a
preventative measure to ensure the surrounding environment or any other factor is not
damaging or interfering with the performance of the analyzer.
2.1 Confi guration
The XZR200 may be recon fi gured at any time by adjusting the position of the header
pin jumper links on the interface PCB.
!
Prior to re-confi guration the unit MUST be powered down. The
jumper links MUST also be re-positioned correctly and in the
correct orientation.
Failure to adhere to the above could result in product damage.
Products damaged due to incorrect confi gurations will not be
covered under warranty.
1. Power down the analyzer
2. Remove the lid using a Phillips (cross head) screwdriver.
3. Adjust the position of the jumper links to the desired con fi guration.
Thin-nosed pliers should be used to remove and replace the jumper links. Ensure the
jumper links are correctly seated before reapplying the power.
JUMPER LINKS
RS232 Rx
0 to 10 VDC OUTPUT
RS232 Tx
4-20mA OUTPUT
Figure 1 Jumper Con fi guration for Output Selection
When selecting the output, you must choose either 4-20mA and 0 to 10 V DC or RS232
Tx and Rx. Ensure the jumper links are always inserted horizontally between 2 adjacent
pins. Place the jumper link(s) into the relevant position(s). Two jumper links are required
for RS232 (positions 1 & 3) and only one jumper link is required for either 0-10 VDC
(position 2) or 4-20 (position 4). NOTE: If only using one jumper link make sure
the other jumper link is stored safely for future use.
