Factory Settings In order to use the DCCT Pro2, you will need to adjust the instrument settings to suit your specific application – see page 9. The following is a summary of the settings as set in the factory:... -
Page 7: Overview
Buckleys DCCT instruments are purpose designed, based on over forty years’ production of HV Non- Destructive Test (NDT) equipment for industry. The instrument provides a highly stable user-controlled HV DC output, from 0.9-40kV, and an adjustable sensitivity alarm whose threshold may be set between... -
Page 8: Hv Testing Basic Physics
This is to reduce the risk of the test inadvertently damaging the material being tested. The ideal approach is to identify an appropriate calculated voltage (Buckleys are happy to provide advice) and then to test this in a range of scenarios to ensure that the desired detection level is achieved without causing unwanted material damage. -
Page 9: Instrument Output Limits
Instrument Output Limits Buckleys DCCT instruments are designed to provide a limited output current, primarily to ensure that the output remains within the limits specified by the IEEE to prevent a lethal shock to anyone accidentally touching the HV electrodes or wiring. This has the effect of limiting the output power at any given voltage, as can be seen in the graph in Fig 2. -
Page 10: Instrument Range
All instruments are capable of networking, allowing up to four output units to be connected to a • single command station. DCCT Pro2 Integral – Single Output (6002-0098) This is the basic instrument which replaces the previous generation of DCCT. It provides a digital user interface, and a single channel output assembly. -

Buckleys has considerable experience in the design and manufacture of HV and Grounding electrodes and we are happy to advise, and to quote for custom installations including extrusion of films and membranes, and a wide range of coated components including wires, cables and flexible and rigid pipes. -
Page 13: Installation Setup - General
If these resources do not resolve your query, Buckleys will provide support and guidance in the use and set-up of the instrument by phone and email. However, please understand that we cannot control the circumstances of operation, and it remains the user’s responsibility to ensure safe and satisfactory... - Page 14 Various standards are available, and Buckleys can provide guidance. However, in all cases, it is recommended to first test on sacrificial samples to confirm the theoretical approach.
- Page 15 SLOW MODE In SLOW mode, the counter will not increment if a flaw is detected during a pre-existing (user adjustable) alarm ON period but will do so if a flaw is detected immediately following an alarm indication. Fig 9 – SLOW MODE VERY SLOW MODE In VERY SLOW mode, the counter will not increment during a pre-existing alarm indication, nor during a (user adjustable) OFF period thereafter.
- Page 16 Instruction Manual These modes are supported by three user-adjustable timer settings. Alarm (ON) Period This is the period of time that an alarm will remain active. It may be adjusted from 0 to 5000ms. A period less than 15ms may not provide adequate time to ensure that the relay changes state. No-Alarm (OFF) Period This is the period of time following an alarm that a further alarm is inhibited in VERY SLOW MODE.

Page 17: Setup (Continued)
Fig 12 – Network Connections Interlock Loop Connection Buckleys always recommends that HV electrodes should be installed in an area from which staff are excluded when they are energised. This is particularly important where the Command+ module is used, and it may not be possible to verify visually that the area is safe before energising HV. To facilitate this, the instruments are provided with interlock connections which will disable the HV generator if the loop is not closed. - Page 18 11 & 12 of the green 12- way connector. Buckleys do not recommend the use of a latching switch or button in this application. A remote-button handle should not be used in multi-channel applications.

Page 19: Instrument Setup - User Menus
Instrument Setup – User Menus The DCCT instruments are controlled via the on-screen menus, and the soft keys on the front panel. The metal button marked with the yellow warning symbol is used to energise the HV output. Access on-screen menu by pressing button which is also used to select menu options and/or confirm adjustment of set values. - Page 20 Instruction Manual Fig 18 – Home Screen – HV Energised Pressing the button again will turn HV off and the screen will return to the previous version. The symbol indicates that the button will access the Main Menu. Use of the buttons will highlight through the Voltage set point, Alarm Threshold set point and the windows for each connected output unit in turn.
- Page 21 Fig 20 – Parameter Adjustment (Voltage, Alarm Threshold, Alarm Timings) Once the required parameter has been selected, use of the buttons will increment or decrement the value as required. Holding the button will scroll the value rapidly after a short delay. The same process is used to adjust the Alarm Current Threshold, and the timing parameters accessible through the Fault Report Menu.
- Page 22 Instruction Manual Entering the Main Menu provides the screen shown below: Fig 22 – Main Menu Screen As noted above the buttons labelled are used to scroll up and down the menus, and the is also used to select a menu option. Selection of the Totaliser Count and followed by will clear the count.
- Page 23 The Fault Report Menu offers control of the relay timing as discussed above (please refer to Figs 8 & 9 and associated text above) Fig 24 – Fault Report Menu The menu items are accessed in the normal way, and the buttons allow the parameters to be selected from the menus provided.
- Page 24 Dealer or Distributor, or returning it to Buckleys – this is likely to be inconvenient! Fig 26– Passcode Entry (Set/Clear Manager Passcode) If a Manager Passcode has not been set, the Access Level will be User.
- Page 25 Fig 27– Home Screen with 4 Output Modules attached. The four output unit windows on the whole screen are therefore respectively nodes 80 & 81 on the upper row, and nodes 82 & 83 on the lower. Physical connection of an output unit to the network will populate the next available node, and this is typically convenient.
- Page 26 Instruction Manual Proceed as follows: Use the buttons to select Nodes Populated and then 80. Press Press again. Use the button to select 82. Press Press the button twice to select Save and Enter. Press Use the button to select Nodes Populated and then 81. Press Press again.

Page 27: Useful Advice
This method is less precise and will not detect weak or thin areas as readily. It is recommended to consult with Buckleys in this situation as a multi-channel approach may provide an optimum solution to the issues of excess quiescent current draw. -
