Installation

3.8.2 Add probe connections

When all probe connectors on the sc1000 controller are already in use for probes, more probe connectors can be added (max. 8 probe connectors). It may be necessary to remove an existing expansion card if accessibility to probe connectors is obstructed (refer to section 3.6.6 on page 37).

Note: If a probe module has the maximum number of probes, more probes may be added to the system by purchasing additional probe modules.

To add probe connections:

1.Remove power from the instrument. Open the probe module cover.

2.Remove the fitting or plug from a spare probe socket hole.

3.Screw a new probe connector into the housing and connect the probe connector to a probe connection on the main circuit board. Any available probe connector can be used.

4.Assemble the housing.

3.8.3Connect AC powered sc probes

Note: AC power outlets can only be connected when a 100 V–240 V power supply is fitted in the sc1000 controller.

Most sc-probes draw power directly from the sc probe connection. However, certain sc probes may require supplemental 100–240 VAC power (e.g., to run pumps or heating elements). These AC powered sc-probes have two cables that connect to an sc1000 probe module: a standard sc-probe connector and a special connector for drawing AC power from the probe module.

To connect AC powered probes to a probe module:

1.Unscrew the cover on the AC power outlet.

2.Connect the power connector from the analysis instrument to one of the AC power outlets.

3.Connect the sc-probe connector to any available sc-probe socket.

3.9Service port connection (LAN connection)

The service port of the sc1000 controller is a 10 MB/s Ethernet interface at the display module (Figure 7). To use the service port, connect an Ethernet cross-over cable from a computer to the service port. The Ethernet connection can be used to run all sc1000 controller functions or calibrate the probes through any web browser.

Configure the network adapter inside the computer to communicate with the sc1000 controller.

Important Note: It is recommended to use an external Ethernet USB network adapter as an interface to the sc1000 controller. The use of a second network adapter makes sure that the sc1000 controller connection does not have any impact to the default local area network (LAN) connection (for example the regular office network).

To setup and prepare a LAN connection, refer to section 5.13.1 on page 67 and section 5.13.2 on page 67.
