4. Seadistamine

Follow these steps to set up your PWM150 Signal Generator:

1. Toiteühendus: Connect a DC power supply (5V-24V) to the "INPUT" terminals on the rear of the device. Ensure correct polarity (+ to +, - to -).
2. Väljundühendus: Connect your target device (e.g., servo motor, LED driver) to the "OUT1" and "OUT2" terminals for Channel 1 and Channel 2, respectively. Observe correct polarity and ensure the load does not exceed 0.2A.
3. Esialgne sisselülitamine: Once connections are secure, apply power. The display should illuminate, showing default frequency and duty cycle values.

5. Kasutusjuhised

5.1 Põhitoimingud

1. Toide sisse: Connect the power supply. The device will power on and display the last saved settings or default values.
2. Valige kanal: Vajutage nuppu MOD key to switch between Channel 1 (CH1) and Channel 2 (CH2). The active channel will be indicated on the display.
3. Reguleerige sagedust: The upper green display shows the frequency. Rotate the Pöördkooder to adjust the frequency. Short press the encoder to select which digit to adjust (the selected digit will flash).
4. Adjust Duty Cycle: The lower white display shows the duty cycle (%). Press the MOD key until the duty cycle is displayed for the selected channel. Rotate the Pöördkooder to adjust the duty cycle from 0% to 100%.
5. Start/Stop Output: Vajutage nuppu VÄLJAS key to start or stop the PWM signal output for the currently selected channel. A green LED next to "OUT" will illuminate when the output is active.

5.2 Synchronization Mode

The PWM150 allows for synchronization of parameters between CH1 and CH2.

1. Enable Sync: Vajutage nuppu SYNC button. The display will indicate that synchronization mode is active.
2. Adjust Synchronized Parameters: In sync mode, adjustments made to frequency or duty cycle on one channel will automatically apply to the other channel.
3. Adjust Phase: When in sync mode, you can adjust the phase difference between CH1 and CH2. Press the MOD key until the lower white display shows the phase (e.g., 0°). Rotate the Pöördkooder to adjust the phase from 0° to 360°.
4. Disable Sync: Vajutage nuppu SYNC button again to exit synchronization mode.

5.3 System Settings (SET Key)

Vajutage nuppu SET key to access advanced settings. Use the Pöördkooder to navigate and adjust values, and the SET key again to confirm or exit. Refer to the on-screen prompts for specific options, which may include:

• Power-on output state (on/off).
• Saving and recalling custom parameter settings.
• Setting upper and lower limits for frequency and duty cycle.
