1 Introduction

A generic temperature controller has been designed and the unit was subsequently installed [1]at our station in South Africa. The Sutherland Temperature Controller was a success and as aresult it has been decided to roll out similar units to the other stations within the BirminghamSolar-Oscillations Network (BiSON) as and when convenient.

As Narrabri had not been visited for a couple of years, it was decided that a station visitwas in order. During the trip, the temperature controller should be upgraded as one of the maintasks.

The temperature controllers in Narrabri were replaced [2] in 2010 February. The temperaturecontroller unit is described in BTR-321. This report details the exact configuration of theNarrabri Temperature Controller.

2 Unit Design

The Narrabri Temperature Controller like many other units is housed in a 2U 19” rack case withits own internal power supplies.

The front panel looks very similar in design to other units that are built by HiROS.

2.1 The Front Panel

The front panel of the Narrabri Temperature Controller is shown in Figure 1. There are fourmain elements on the front panel.

On the left there is the HiROS standard power switch. Next there are two power-LEDboards showing the status of the analogue and digital power supplies respectively. Finally onthe right-hand side of the front panel is the HiROS standard RS232 LED board.

Figure 1: The Front Panel of the Narrabri Temperature Controller.

2.2 The Rear Panel

Figure 2 shows the layout of the rear panel of the Narrabri Temperature Controller. On theleft of the unit is the case fan. In the centre of the rear panel are all of the D-type connectorswhich are used to feed temperature readings and power to the various temperature controlledcomponents. Finally on the right-hand side are the connectors for power and the connection tothe computer.

Figure 2: The Rear Panel of the Narrabri Temperature Controller.

2.3 Internal Layout

Within the Narrabri Temperature Controller there are two transformers and several printedcircuit boards. Figure 3 shows the arrangement of the major components used in the unit. Notethat all panel mounted components have been omitted for clarity.

There is a large digital or “dirty” transformer which provides the power to the high-currentheaters/coolers and a smaller transformer for the analogue or “clean” supplies. There is also alarge Main board and two smaller drive boards.

As there are two transformers that require a mains feed a terminal block connector (TB1) isused rather than splicing cables.

Figure 3: The Internal Layout of the Narrabri Temperature Controller.

2.4 Parts List

The parts list for the Narrabri Temperature Controller is too large to fit in a single table. Henceit has been split into several smaller tables according to component type. These tables aresummarized in Table 1. A spare parts kit is also supplied.

3 Internal Wiring

The Temperature Controller system is made up of several different PCBs and the layout withinthe case has already been shown in Figure 3.

Most of the electronics for the Temperature controller are contained on the Main board. Theunit does require eight high-current outputs and these are provided by the two drive boards,each board having four such outputs.

Because the system contains different PCBs it means that there is a lot of interconnectionsthat need to be made internally on the system wiring.

4 PCB Configuration

The Temperature Controller [3] is a generic device that can be configured in many different waysdepending on the actual components that are present.

The spectrometer Genghis as fitted in Narrabri has the following components that requiretemperature control:

• Port Detector.

• Starboard Detector.

• Oven.

• Interference Filter.

4.1 Output Channel Allocation

The Narrabri Temperature Controller requires two of the drive boards to enable it to controlthe temperatures of components within Genghis and the ancillary outputs that are needed bythe temperature controller itself.

Table 9 shows how the components have been allocated to the available output channels onthe Narrabri Temperature Controller.

4.2 Output Configuration

Figure 9 shows a generic version of the output stage of the temperature controller. The drawingcontains a number of components that are changed to enable the unit to control different typesof component.

There are components on both the main board and on the drive board that are changeddepending on the component that they are driving. LKa and LKb on the main board set thereference voltage which determines unipolar or bipolar current range.

Table 10 shows the values of the components as used on the Narrabri Temperature Controller.The gain resistors column shows the names used on the drive board for the components on theoutput in question. For the output link this shows which link to populate with a zero-ohm linkon the drive board. The reference link shows which link to populate on the main board.

6 External Connections & Cable Assemblies

Figure 10 shows how all of the sensors are connected to the temperature monitor. There are ba-sically five different types of cable assemblies that are associated with the Narrabri TemperatureMonitor, these are summarized in Table 15.

6.1 HiROS Signal Cable

The majority of signals have to travel from a remote sensor to some instrument. Because ofthis it was decided to adopt a standard cable that is used on any system that requires signalsto travel over a considerable distance.

The HiROS signal cable is this standard cable. It is basically a network cable that has D-Type connectors fitted on each end. The cable is made up of 4 twisted pairs of 7/0.2 wires.The cables come in a variety of different lengths and several different outer sheath colours areavailable including yellow, blue and red.

Figure 11 shows how the cable is connected internally.

6.2 Genghis Drive Cable

The Genghis drive cable carries all of the high-current power signals from the temperaturecontroller to the spectrometer. The drive cable does not require the use of twisted pair cableand hence normal 7/0.2 cable is used instead.
