4. Setup and Installation
4.1 Mounting the Module
The DSP-10 module is designed for panel mounting. Ensure the mounting hole dimensions are appropriate for the module's size.
- Cut a rectangular opening in the control panel according to the module's dimensions.
- Insert the DSP-10 module into the opening from the front.
- Secure the module using the provided mounting brackets on the sides. Push the brackets firmly until the module is snug against the panel.

- Power Supply: Connect the module to the appropriate DC power supply (e.g., 12V or 24V DC) as specified by the module's requirements.
- Voltage Inputs: Connect the generator's phase voltages (L1, L2, L3) to the corresponding voltage input terminals.
- Current Transformer (CT) Inputs: Connect the secondary windings of the current transformers to the module's current input terminals (A+, A-). Ensure correct polarity.
- Frequency/Hour Meter Input: Connect the appropriate signal for frequency and hour meter readings.

4.3 CT Ratio Configuration
The DSP-10 module features DIP switches (J2-8) on the rear for configuring the Current Transformer (CT) ratio. Refer to the "PROGRAMMER TABLE" printed on the module to set the correct ratio for your CTs. Incorrect settings will result in inaccurate current readings.
| DIP Switch Setting (1-5) | CT Ratio |
|---|---|
| ON-OFF-OFF-OFF-OFF | 50A |
| OFF-ON-OFF-OFF-OFF | 100A |
| ON-ON-OFF-OFF-OFF | 150A |
| OFF-OFF-ON-OFF-OFF | 200A |
| ... | ... |
| OFF-OFF-OFF-OFF-ON | 1200A |
Note: The exact "PROGRAMMER TABLE" is printed on the back of the DSP-10 module. Always refer to the physical module for accurate settings.
5. Operating Instructions
Once installed and powered, the DSP-10 module will automatically display key generator parameters.
5.1 Display Overview
The front panel features three digital displays and three control buttons:
- Top Display: Typically shows Line-to-Line Voltage (L12, L23, L31).
- Middle Display: Typically shows Line Current (L1, L2, L3).
- Bottom Display: Typically shows Frequency (Hz) or Run Hours (Hr).
5.2 Button Functions
- V (Voltage) Button: Press to cycle through different voltage readings (e.g., L12, L23, L31).
- A (Amperage) Button: Press to cycle through different current readings (e.g., L1, L2, L3).
- Func (Function) Button: Press to cycle through other functions like Frequency (Hz) or accumulated Run Hours (Hr).
The module continuously monitors and displays the selected parameters. No further user interaction is typically required for basic monitoring.
6. Maintenance
The DSP-10 module is designed for minimal maintenance. Regular inspection and cleaning will help ensure its longevity and accurate operation.
- Cleaning: Periodically clean the front panel with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Inspection: Regularly inspect all wiring connections for tightness and signs of corrosion or damage.
- Environmental Protection: Ensure the module remains protected from excessive dust, moisture, and vibrations.
Note: There are no user-serviceable parts inside the module. Do not attempt to open or repair the unit.
7. Troubleshooting
If you encounter issues with your DSP-10 module, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Module does not power on. | No power supply, incorrect wiring, blown fuse. | Check power connections, verify supply voltage, inspect fuses in the power circuit. |
| Incorrect voltage readings. | Incorrect voltage input wiring. | Verify voltage input connections against the wiring diagram. |
| Incorrect current readings. | Incorrect CT ratio setting, incorrect CT wiring polarity, faulty CT. | Check DIP switch settings for CT ratio (refer to Section 4.3). Verify CT wiring polarity. Test or replace CTs if suspected faulty. |
| Display is blank or flickering. | Unstable power supply, internal fault. | Ensure stable power supply. If problem persists, contact support. |
If the problem cannot be resolved using the above steps, contact NYUMMRYT customer support or a qualified technician.
