10. Put the connector back in place (No. 4).
11. Replace the metallic shielding plate, ensuring it is in front of the power cable just installed.
External communications connection
1. Run the communications cable through an external cable gland on
the bottom of the cabinet, and into the analyzer.
2. Pass it through the cable gland located right and farthest from you
on the base of the transmitter, so it appears inside the transmitter
through the left front cable gland.
3. Connect the communication cable as indicated. Connection is the
same on the CPU board for both the JBUS/ MODBUS and
PROFIBUS options.
4. Close the transmitter door and secure in place with the 4 screws.
5. Put the local controller box back in its normal position and secure in
place with the 2 holding screws.
Input/Output connections
Before using any of the cable glands, perforate first with a screwdriver. To ensure a good seal, the
external diameter of the cables should be between 5 and 7 mm. The nomenclature given in the
connections column of the following table refers to the same nomenclature that is printed on the I/O
board against each available connection.
Connections Function
Re1 to Re6 User relays - see Alarms on page 17 for more information on the relays
Re7 Warning alarm
Re8 System alarm
In2 For remote calibration
In4 to In7 By-pass channel measurement (channel 4 - 1 respectively)
Iout0 Used for the current measurement signals
Iout1 to Iout7 Can be freely linked to different parameters like measurement, temperature - refer to the section
entitled mA outputs on page 18 for details
On completion, close the local controller box (No. 11 in Figure 1 on page 7) and secure in place with
the 6 screws.
Sample tubes installation
Connecting the sample
Use new tubes for connections during installation
• Exterior Ø: 6 mm exactly (or ¼'')
• Material: polyethylene or PTFE or FEP
• Flow rate: 6 to 9 L/hour
• Pressure: 0.2 to 6 bar (8-100 psig)
• Sample acidity: sample acidity should not be more than 300 ppm CaCO
3
• Temperature: 5 to 45°C
At this stage of the installation, make sure that the flow valve is closed. Connect the pipes by
inserting them into the quick release connections found on the bottom of the analyzer under the
sampling block (No. 14 in Figure 1 on page 7). Be sure that the sample line is correctly flushed
before any connection to avoid particle injection into the hydraulic system. If particulate matter is
