Cresatech CuTS® Overview

CuTS® is designed to provide an easy and convenient way to remotely monitor ground cabling and components at site locations prone to copper theft.

CuTS® contains everything you need to activate alarms and automatically send alert messages via SCADA and/or one of our managed service options. Providing you with realtime feedback when monitored grounding infrastructure is cut or a ground bar has been removed that is being monitored by one of up to 8 zone monitoring channels CuTS®.

The procedures in this guide outline the steps you should follow to correctly install and operate CuTS®.

CuTS® works by monitoring sites for small changes in inductance within individually monitored zones. CuTS® has a number of integrated software controlled filters to take into account any ambient changes in inductance during ‘normal’ site operation, thus minimizing the risk of false alarms.

**WARNING** Although CuTS® monitors grounding infrastructure components, caution should be taken during installation. Live power lines may be in close proximity to the installation location of ground monitoring equipment leads or the main unit. Do not touch or remove any live AC lines during the installation of CuTS®. Serious Injury or death could occur from electrocution. Be sure to secure trailing test leads, take particular care in windy conditions when leads can be picked up and blown into contact with live power-lines.

CuTS® Installation

Because CuTS® can be used in a variety of applications there are many variations of exactly how CuTS® can be installed and connected to ground lines. Please use the steps below as a guideline for installing CuTS®. Proper testing should be done after installation to ensure you receive the desired level of alarming and alert messages. Installation should only be completed by or under the direct supervision of a Cresatech certificated installation technician who will have been trained to utilise a range of zone identification and connection techniques.

Step 1: Mounting CuTS®

Mount the CuTS® unit in a suitable location inside the shelter, switchgear room or cabinet. CuTS® mounts easily to any flat surface. The mounting holes can be used to mount vertically to wall or board or alternatively flat on a suitable shelf. Strong two−sided tape or Velcro can also be used to secure CuTS® to a shelf.

The mounting location should be in close proximity to the reference point of the ground wires you wish to monitor. There should also be a 110/230vac outlet within 1.5m/4ft of the CuTS® unit.

Step 2: Choose the zones to monitor

Typical locations to monitor are the main installation ground bar (main common reference point) and selected zone end-points. Leads should be run from each zone terminal on the CuTS® to each zone end-point that you wish to monitor. Whilst most sites will utilize the main ground bar as a common reference point for different zone points some sites may require individual reference points for some or all zones dependent upon conditions.

Use an LCR meter to measure inductance, choose a test measurement frequency as close as possible to 34Khz (10Khz is typical). Take measurements between the earth reference point and each zone endpoint. A reading of between 2uH and 200uH is acceptable. For readings outside this range you should consider reducing or changing the zone measurement area. You should test for inductance using leads that are to be used for final zone connections. The maximum recommended distance between the reference point and the remote point is 50m point to point. The leads themselves can be longer to take advantage of available ducting or to preserve a structured layout.

Step 3: Connecting The Zone Monitoring Wires

Connections to the zone end-points and the main ground bars typically utilize 1.5mm to 2.5mm CSA wire with suitable crimp lugs or earth connection clamps. Wires should be run into existing ducts were practicable. If local coding or practice demands the use of larger cables or armoured cables, then these can be connected to zones in the appropriate manner and then brought back to a terminal block or marshalling box to convert to 1.5mm for connection into the CuTS® unit. All wires coming in to the CuTS® unit should be fed through the 25mm compression gland provided. If using flexible conduit, then this gland can be replaced with an appropriate conduit connector.

Typical Connector styles for securing sense wires to grounding infra-structure

Common Reference Point If using a common reference wire for multiple zones from the CuTS® unit then this would normally be connected to the main ground bar inside the switchgear/room/shelter/cabinet. One side of each of the zone connections (for zones using a common reference point) within the CuTS® unit should be ‘daisy-chained’ together. Each remote sense wire for each respective zone should then be connected.

Individual Reference Point For zones using independent references then these wires should be connected individually to each zone as required.

Step 4: Connecting SCADA Alarm Wires

Once connections have been made to all zone sense wires then it’s time to connect SCADA alarm channels (optional). There are connections available for an alarm output from each zone for SCADA channels. If not enough channels are available at the site RTU then alarm output channels can be common connected in parallel or serial as appropriate.

Step 5: Installing Zone Cards

Once all sense wires and SCADA connections have been made then it’s time to install the zone cards. Each card will slide into the card guides and then the connector should snap in when fully home. Card number 1 is the master card and should have a 25way ‘D’ type connector on it. On multi zone systems there will always be two cards with this connector on. The second card is a spare master card and can be installed in any of the other slots.

Step 6: Connecting Battery and External Power Supply/Charger

Feed the lead from the charge in through the 16mm compression gland. This can then be connected to the common battery and charger connector. Take care to ensure correct polarity (CuTS® is reverse polarity protected). Tighten up the gland to secure the cable.

Tuning CuTS® via Cresatech Software

Communicating with CuTS®

There are two ways to connect to CuTS®. If on site for initial set-up it is normal to use the direct cable link to link a laptop directly to the 25way D type connector on Zone card number 1. A flexible 25-way connector will be needed. If connecting remotely then there will already be a modem installed and connected to an IP/SEC network. If you know the appropriate IP address and Port number, you can use the CuTS® software to connect this way from a networked PC or laptop. This is covered later in this manual but the software package used is the same. When connecting to CuTS® using the cable, the unit should first be powered down by removing the green DC connector. Now attach the interface cable and power up CuTS® by replacing the DC connector. Now plug the USB connector into a laptop or PC and open up the CuTS® software. Click on the Comms tab and select ‘serial’. Select Baud rate 9600 and the appropriate port number from the drop down list. This can also be found by checking windows device manager for the USB port occupied by the USB interface cable.

Displaying Zones for Tuning or Observation

CuTS® should now be active and by clicking on icon highlighted in the picture below a window for the first active zone will open. Clicking on the same tab multiple times will continue to open any further active zones to a maximum of 8. These windows can be tiled vertically or horizontally (using the adjacent menu buttons) to allow the operator to view all active zones together for easier site tuning.

In the menu bar is an option to allow the user to make adjustments. There are two levels of menu; ‘settings’ is for normal operation and tuning of the unit, the second ‘engineering’ is for more complex diagnostics for faults or difficult sites normally under direct guidance from Cresatech.

The default password to access the user settings is ‘1234’ and the higher engineering level is ‘4321’.

You will be prompted for a password the first time you access this option during a fresh session. Remember before leaving site to change these passwords to something of your own choice (simply click on ‘file’ and choose which password you wish to change and follow the on-screen prompts). When you have a settings or engineering window open please note that you can only adjust one zone at a time. The zone number is displayed in the top corner of the window. Change this number to switch to another zone.

Please note that there are two main buttons on the window marked ‘GET’ and ‘SET’. ‘GET’ retrieves the information from the selected zone card. ‘SET’ sends new settings to the selected zone card. Remember when selecting another zone card that you should ‘GET’ settings before using the ‘SET’ command or you risk overwriting the new zone with settings from the previous zone. Adjusting Alarm Signal for Each Zone

Each zone will display a high alarm threshold (red), low alarm threshold (green), average signal output for the monitored zone (white) and baseline level (blue). Basic operation of the unit is simple. If the white line crosses either high or low alarm then after a pre-selected time delay (user adjustable) an event alarm will become active. This will in turn trigger a closure (or opening depending on selected logic) of the alarm output channel for that zone and also trigger an email (when modem is connected and configured) which will report the alarm event via the Cresatech managed service.

Applying Filters to Zone Signals

In order to reduce the risk of false alarms CuTS® incorporates a number of event filters that can be user adjusted to suit the conditions of each site.

Screenshot showing zone signal settings

Baseline Voltage Filter (blue trace) The baseline level shows the signal condition of the monitored zone without the influence of the internal oscillator. This is useful to determine if any ambient voltages are present that may affect the alarm signal. Voltages can be caused by induction or more commonly by radio equipment such as power-line communications signals on site. The voltage filter threshold can be adjusted using the slider control to limit or ‘squelch’ the effects of such voltages

Average Sample Time Filter (white trace) This option enables the user to select the length of time over which the alarm monitoring signal is averaged. This is useful for ‘damping’ the signal reaction. 5 seconds is the default setting although 30 seconds is more normal for a substation environment

Connecting the Modem for Remote Operation Once all settings have been configured its time to connect the modem to the Zone card in slot number 1.

First power down the unit and then disconnect the serial cable from the zone card. Make a note of the SIM card number and then Place the SIM card into the modem. If the SIM card is already installed then the modem will have a sticker on it denoting its IP address and Port number, make a note of these if present.

Now carefully plug the modem into the 25-way D connector on the zone card in slot 1. Make sure it is pushed fully home, it is advisable to support the card whilst doing this.

Alarm Event Timer Once a high or low alarm threshold has been breached, this setting enables the user to set a time delay that denotes how long an alarm condition should remain present before the alarm output is triggered. This helps to filter out any short-term ‘spikes’ that get through the array of other filters.

Alarm Hysteresis Setting Once an alarm output has been triggered this setting allows the user to create a lower threshold that must be reached before the alarm trigger is reset. This function prevents ‘chatter’ when an alarm event is close to the trigger threshold.

Testing Alarm Functionality To test alarm functionality simply ‘lift’ a sense wire and watch to see if the alarm signal trace breaches either the low or high alarm level. This should then (after all filters are taken into account) result in a live alarm event being shown on the relevant RTU channel.

Now plug in the internal aerial (supplied with the unit) to the modem. If in a poor signal area a separate external antenna can be used.

Now power-up the unit. Modem Indicator LED’s The Modem has a number of diagnostic LED’s (visible along the top edge of the modem when it is energised) which flash to indicate various states of operation as follows:

Modem At Power-On Green on solid. Then: Yellow flashes whilst modem connects to GSM network. Then: Yellow on solid, modem connected & online. Then: Red/Orange on when signal strength has been read. Modem now has Green Flashing slowly, Yellow & Red LEDs on Solid. All good, modem listening. ModemEmailingGreen,Redoff. Yellow on, flashes a couple of times during emailing. If Red LED flashes, the email operation has failed. Modem Online & Listening for incoming socket Green flashing slowly, Yellow & Red LEDs on solid. Modem rebooting after Inactivity Green, Yellow, Red on for 5 seconds. Green extinguishes, then 5 seconds later Yellow extinguishes, then Red extinguishes. Modem reboots (This is necessary in order to clear network errors that may be present and is a normal function of the modem). Test Comms Link via Modem Once the modem has acquired a network connection run the CuTS® software and choose the ‘comms’ tab and then click on ‘set-up’. Choose TCP and fill in the IP address and port number details of the modem connected to the CuTS® unit that you wish to test. Open up the zone monitor windows as before and observe.

It is a simple matter to run the alarm function checks by test lifting zone connections as before and waiting for an email confirmation of the alarm event. All user functions are available via the TCP connection as they were during direct cable connection. Now select Zone 1 and check the enclosure tamper status, it should show ‘active’ Now it’s time to mount the tamper/tilt detection sensor. The sensor is part of the kit and comes ready with Velcro for mounting This needs to be stuck to the inside of the lid depending upon orientation of the CuTS® unit. If CuTS® is mounted vertically, stick the sensor to the inside of the lid, if mounted on a shelf then the sensor should be stuck onto the inside of the side of the lid. The sensor should be mounted so that when the lid is in position, the sensor can be adjusted vertically up or down in a vertical plane. The sensor has long leads to enable fine adjustment later. Now plug in the lead from the tamper detection switch into the tamper connector on the backplane. Adjust the tamper sensor so that it faces approx. 5 to 10 degrees up from horizontal when the lid is in the correct position. Now close the lid and secure it with the screws. If not using the sensor, then simply bridge the sensor connector with a short wire link. Recheck the tamper alert, it should now be showing ‘inactive’. To test, remove the lid whilst observing the tamper status via the CuTS® software. The status should become ‘active’ and an email alert will be received. Replace the lid and secure it with the screws. The tamper alert should now clear. Software Security

The default password to access the user settings is ‘1234’ and the higher engineering level is ‘4321’. Remember before leaving site to change these passwords to something of your own choice. Click on ‘file’ and choose the password for each menu level. Please also remember to make a note of these on the installation sheet.
