2. Introduction
This document describes the commissioning of the CP Controller.
2.1. Typical System Wiring for Cathodic Protection Systems
As a CP system works by passing current through ‘ground’, it is essential that the system Common (the Positive potential) is only grounded at the output of the CP Controller. If a ground connection is made at any other point in the system, it is possible that the CP Controller will not be able to monitor or control the output current and voltage correctly, particularly if a reference electrode is used.

Grounding of Enclosures
The grounding of enclosures and structures is acceptable, but under no circumstances should a connection be made from the system common to a metal enclosure or structure otherwise the protective current is liable to have an adverse effect on these parts, and in some cases may accelerate corrosion.

3. Commissioning
3.1. Input Power
On the CPC Control PCB Assembly, ensure the Enable/Disable switch is set to the DISABLE position.
Turn on the power to the CP Input terminals.
On the CPC Control PCB Assembly, ensure the green Status LED is illuminated.
3.2. Initial Output Set-points
To start with Constant Voltage Control:
Navigate to Menu 0 Screen 1 and set the Output Voltage Set-point = 0.0V (minimum)
Navigate to Menu 0 Screen 2 and set the Output Current Set-point = 5.0A. This is given as an example of the required output current – set it to the output current desired.
Navigate to Menu 0 Screen 3 and set the Half-Cell Voltage Set-point = 5.0V. Setting the Half-Cell Voltage at its maximum ensures that the half-cell control will not interfere with Constant Voltage Control.
3.3. LCD Display
Verify the LCD display indicates the following ± 0.3 (assuming there is no half-cell fitted):
Voltage Current H-Cell
00.0V 00.0A 0.0V Actual
00.0V 5.0A 5.0V Set-Points
Note: If a Half-Cell (Reference Electrode) is fitted, the indication on the Half-Cell meter should match the structure to soil potential (as measured by a portable half-cell and meter).
Note: If a Half-Cell is not fitted, then ensure a wire link is fitted across the Half-Cell input terminals.
3.4. Constant Voltage Control
On the CPC Control PCB Assembly, ensure the Enable/Disable switch is set to the ENABLE position.
The Cathodic Protection Controller can now be set up to operate at the required level in the appropriate operating mode.
Voltage Current H-Cell
00.0V 00.0A 0.0V Actual
00.0V 5.0A 5.0V Set-Points
Increase the Output Voltage Set-point (Menu 0 Screen 1). The voltage and current actual values should indicate an increase as the set-point is increased. The CP Controller is operating in Constant Voltage Mode (readings dependant on ground conditions – example shown is 1.0 ):
Voltage Current H-Cell
4.0V 4.0A 0.0V Actual
4.0V 4.0A 5.0V Set-Points

CP Commissioning Procedure
MF Page 3 of 4 The Micha Design Company Ltd
3.5. Constant Current Control
Continue to increase the Output Voltage Set-point (Menu 0 Screen 1) until the voltage and current actual values indicate no further increase. The current actual value should equal the current set-point value (e.g. 5.0A). The CP Controller is operating in Constant Current Mode (readings dependant on ground conditions – example shown is 1.0 ):
Voltage Current H-Cell
5.0V 5.0A 0.0V Actual
6.5V 5.0A 5.0V Set-Points
3.6. Half-Cell Voltage Monitoring
This is only applicable if there is a Half-Cell (Reference Electrode) connected.
Note: If no Half-Cell is fitted, a wire link should be fitted to short out the Half-Cell terminals.
With the supplied software for this project, no Half-Cell control is available, but the value on the input terminals is sampled with the value displayed on the screen. The set-point should be set to 5.0V.
3.7. Disable Input
Connect a wire link across the Disable Input terminals and note that the CP Output Current drops to zero.
Remove the wire link across the Disable Input terminals and note that the CP Output Current goes back to its previous value.
3.8. Interrupt Timer
Navigate to the Interrupt Timer Set-up Screen (Menu 2) and ensure that the Interrupt Timer is set for 10 seconds on and 10 seconds off.
Navigate to Menu 2 Screen 1: “Int Tim: Disabled Select to change”. Activate the Interrupt Timer by pressing Select.
Navigate to Menu 0 Screen 0. Check that during the OFF time, the Output Current indicated on the LCD Display falls to zero, and LED6 (Disable Input) illuminates. Check that during the ON time, the Output Current indicated on the LCD Display returns to the Output Current Set-point and LED6 extinguishes.
Navigate to Menu 2 Screen 1 and de-activate the Interrupt Timer by pressing Select.
3.9. Alarm Relay Test
Navigate to Menu 3 Screen 3 and press Select to change the state of Alarm Relay 1
Navigate to Menu 3 Screen 4 and press Select to change the state of Alarm Relay 2
Navigate to Menu 3 Screen 5 and press Select to change the state of Alarm Relay 3
Use a continuity meter or a DVM set to resistance to check the change in status of the Relay contacts.
