۴.۲ د بریښنا رسولو اختیارونه

The signal generator offers flexible power supply methods:

• External 24VDC Terminal: Connect a 24VDC power source to the designated terminals.
• د USB ډول-C: Use the provided USB Type-C cable to connect to a power adapter or computer.
• Rechargeable Li Battery: The device supports an internal rechargeable lithium battery (not included). When a battery is installed, it can be charged via USB Type-C or external 24VDC while in use.

1.4 د ارتباط ډیاګرام

Refer to the following diagram for proper terminal connections. Terminal numbers are read from left to right (1-9).

شکل 1.4: Terminal Connection Diagram.

• GND (1): Power supply negative (input). This is the same as 9-GND and can be arbitrarily connected.
• ۱۲ وولټ (۲۵): Power supply positive (input). External power input to power or charge the meter.
• mA i (3): Current signal input positive.
• Vi (4): والیtage signal input positive.
• LP+ (5): EXT 24V input (passive mode).
• mA o (6): Current signal output positive. The current output is commonly used in active mode. The output of the meter 6-mAo 9-GND corresponds to positive and negative current input of the PLC.
• Vo (7): والیtage signal output positive. The voltage محصول 7-Vo 9-GND corresponds to the positive and negative voltage input of the PLC, or it can be measured directly with a multimeter.
• PWM (8): PWM output positive.
• GND (9): Signal common ground (internal connect to ①-GND).

Current Sink Two-Wire Output: سره وصل کړئ 24V + ته 5-LP+ terminal of the meter head, and output from the 6-mAo terminal to control the current of the external 24V. The meter head is equivalent to a variable resistor, so it is called passive mode. Direct measurement cannot detect the current, and it can be directly replaced with a passive two-wire pressure/temperature sensor, etc.

2.2 DC Voltage او اوسنی محصول

• والیtage DC Analog Output Range: ±12V (with short circuit protection).
• Current DC Analog Output Range: 0-24mA (short circuit protected).
• د محصول سمون: Users can freely set the output range, such as 0-20mA, 4-20mA, 0-10V, 0-5V, etc. The corresponding engineering display values can also be set.

2.3 PWM Pulse Square Wave Output

• Adjustable Frequency: 1-150kHz
• Adjustable Duty Cycle: 0-100٪.
• لوړه کچه: 5V
• غوښتنلیک: PWM pulse output high level is 5V, low level is 0V. It can directly drive buzzers, LEDs, optocouplers, etc., or connect to 12V/24V systems through external level conversion modules.

3. ساتنه

To ensure the longevity and optimal performance of your Luqeeg Signal Generator, follow these maintenance guidelines:

• پاکول: Use a soft, dry cloth to clean the device. Avoid using abrasive cleaners or solvents, which can damage the casing یا سکرین.
• ذخیره کول: وسیله په یخ او وچ ځای کې د مستقیم لمر وړانګو، سختې تودوخې او لوړې رطوبت څخه لرې وساتئ.
• سمبالول: Handle the device with care to prevent physical damage. Avoid dropping it or exposing it to strong impacts.
• Battery Care (if installed): If using a rechargeable Li battery, ensure it is charged regularly, even if not in frequent use, to maintain battery health. Do not expose the battery to extreme heat or puncture it.
• محافظتي فلم: The surface protective film of the sticker can be peeled off for clearer viewing.

4. ستونزه حل کول

This section addresses common issues you might encounter with your signal generator.

• وسیله نه فعاله کیږي:
  • وګورئ چې ایا د بریښنا سویچ په "آن" حالت کې دی.
  • Ensure the USB Type-C cable is securely connected and the power source is active.
  • If using external 24VDC, verify the power supply is connected correctly to the terminals and is providing the correct voltage.
  • If using a rechargeable battery, ensure it is charged.
• د محصول سیګنال نشته:
  • Verify that the output parameters (voltage, current, PWM frequency, duty cycle) are set correctly on the display.
  • Check all connections to the output terminals for proper contact.
  • Ensure the device is powered on and functioning.
• Incorrect Output Readings:
  • Confirm that the measurement range is appropriate for the signal being measured.
  • Check the calibration settings if custom ranges have been configured.
  • ډاډ ترلاسه کړئ چې ټولې اړیکې خوندي او له مداخلې څخه پاکې دي.
• PWM Output Compatibility:

  یادونه: The PWM output of this device is not suitable for 12V or 2V systems, as 5V is regarded as a low level in these systems. For such applications, an external level conversion module is required.
