1.0 General
Switch mode power supply for cathodic corrosion protection applications
The REOTRON SMP range of DC Power units are primary-switched power supplies with galvanic isolat-
ed output voltage. The units can be used voltage controller or current controller, or as a combined unit to
control both voltage and current. The units can be operated locally from a control panel or (switchable)
from external control signals.
Set point inputs for current and voltage are provided for external control. The set point signals may be a
control voltage 0…+10 V, DC or a control current 4…20 mA. In addition it is possible to switch ON and
OFF the output electronically (without galvanic separation) by the means of an inhibiting input. This inhib-
iting input can be operated with a potential-free contact or a control voltage +24 V, DC.
To monitor the protective current the effective actual values of current and voltage are generated by one
each 4…20 mA control signal and are available on terminals.
With an interface option can be communicated via Fieldbus (Profibus-DP, DeviceNet, CAN-Bus or Ether-
CAT) connection.
The units are built into compact aluminium enclosures for the assembly into a switching cabinet.
SMP-CP/M
To monitor the protection current, the actual values of current and voltage also displayed by analog
measuring instruments

4.0 User controls
4.1 Controls
The six buttons and a LED display found in the front-
panel are used for operating and setting up the unit.
All operating methods and adjustable parameters can
be set up through this panel.
The “I” and “O” buttons are used for switching the unit
ON and OFF, however, this does not provide
mains isolation, it simply inhibits the power semi-
conductors.
The “P”, “F” and “Cursor Buttons” are used for pa-
rameter adjustment. Parameters are set by using
menu controls which are called up by entering opera-
tor codes. A capital letter is used to indicate the se-
lected function.
4.2 Adjustment:
The display value can be increased or decreased by units, or tenths of units, by a short press of either
cursor button. Holding a button down will cause the display to change in units of ten.
To prevent accidental or unauthorized adjustment the adjustment parameters, in the user menus, are
protected. A code must be entered to open the user menus. There are different pass codes for each func-
tion group.
Setting adjustments are automatically saved upon leaving the programming mode or if no button
is pressed for a period of 100 seconds.
4.3 Adjustment procedure
All setting routines are commenced by pressing the programming button “P”. The following diagram
should clarify the sequence in which keys are pressed:
1. Press the “P” key.
2. Select the code number with the cursor keys.
3. Press the “P” key. This displays the first menu point. The required menu point can be found by re-
peatedly pressing the “P” key (scrolling).
4. The value in the menu point can be changed with the cursor keys.
5. Scroll to the next menu point or to the end of the menu, which returns the display to the set point val-
ue, by pressing the “P” key. To exit the menu and return back to the normal display quickly, depress
the “P” key for 5 seconds.
6. To return back to the previous position in the menu, press the “F” key

4.4 Display messages
During normal running mode ‘run’ is shown in the LED display. In the programming mode an abbreviation
for the corresponding parameter (see setting up instructions) and its set value, are displayed. Setting
changes are stored upon leaving the programming mode or if a key is not touched for a period of 100
seconds.
4.4.1 Operating modes
Initialisation Phase. When the supply voltage is connected (Left decimal point blinks)
Normal operation
Unit not enabled
Switched-off using “0 – key”
Left-hand decimal point in display illuminated. Current regulation mode; maximum
unit current or the set-point value for current regulation has been reached.
Under Voltage, input voltage to too low.
4.4.2 Fault messages
Over-temperature
Short circuit (internal)
Overvoltage, input voltage too high, output is inhibited
Use `C009` to reset
Unspecified error message, please contact the manufacturer.
When there is a fault an "Error" message is displayed and the unit switches off internally. The unit can be
reset using the green "I" button on the display or in menu "C 009".
