4.2 വയറിംഗ് കണക്ഷനുകൾ

Refer to the wiring diagram on the back of the device and Figure 3 for correct connections. Always ensure power is off before making any wiring connections.

Figure 3: Rear Terminal Block and Wiring Diagram

• Power Supply (90-265V AC/DC): Connect your main power supply to terminals 1 ഒപ്പം 2.
• Auxiliary Power Supply (24V DC): If your sensor requires power, connect the 24V DC auxiliary power supply to terminals 3 (+) കൂടാതെ 4 (-).
• Alarm Output 1 (AL1): Connect your alarm or control device to terminals 5 ഒപ്പം 6. These are normally open (NO) relay contacts.
• Alarm Output 2 (AL2): Connect your second alarm or control device to terminals 7 ഒപ്പം 8. These are also normally open (NO) relay contacts.
• Signal Input (0-75mV / 4-20mA): For mV or mA signals, connect the common (COM) to terminal 9, and the signal (+) to terminal 10.
• Signal Input (0-10V): വോളിയത്തിന്tage signals, connect the common (COM) to terminal 11, and the signal (+) to terminal 12.

Important: Ensure correct polarity for DC power and input signals to prevent damage to the device or inaccurate readings.

5. പ്രവർത്തന നിർദ്ദേശങ്ങൾ

5.1 ഫ്രണ്ട് പാനൽ നിയന്ത്രണങ്ങൾ

• പിവി ഡിസ്പ്ലേ: Shows the current Process Value (measured input).
• SV ഡിസ്പ്ലേ: Shows the Set Value or alarm thresholds.
• SET ബട്ടൺ: Enters parameter setting mode and confirms selections.
• <<RST Button: Shifts digits during setting or resets certain functions.
• Up (▲) Button: Increases values or navigates through menu options.
• Down (▼) Button: Decreases values or navigates through menu options.
• AL1 / AL2 Indicators: Light up when Alarm 1 or Alarm 2 conditions are met.
• ഔട്ട് സൂചകം: May indicate general output status (e.g., if a control action is active).

5.2 അടിസ്ഥാന പ്രവർത്തനം

1. പവർ ഓൺ: After completing all wiring, apply power to the meter. The display will light up, showing the current measured value (PV).
2. Viewing Set Values: In normal operating mode, the SV display typically shows the current setpoint or alarm threshold.
3. അലാറം സൂചന: If the measured PV exceeds or falls below the configured alarm thresholds, the corresponding AL1 or AL2 indicator will light up, and the associated relay output will activate.

5.3 Parameter Setting (General Guide)

The specific parameter setting procedure may vary slightly depending on the firmware version. Generally, follow these steps:

1. ക്രമീകരണ മോഡ് നൽകുക: അമർത്തിപ്പിടിക്കുക സെറ്റ് button for a few seconds until the display changes to show a parameter code (e.g., 'P001').
2. Navigate Parameters: ഉപയോഗിക്കുക മുകളിലേക്ക് (▲) ഒപ്പം താഴേക്ക് (▼) buttons to scroll through different parameter codes.
3. Edit Parameter Value: Once you reach the desired parameter, press സെറ്റ് briefly to enter its editing mode. The value will start flashing.
4. മൂല്യം ക്രമീകരിക്കുക: ഉപയോഗിക്കുക മുകളിലേക്ക് (▲) ഒപ്പം താഴേക്ക് (▼) buttons to change the value. The <<RST button can be used to shift the cursor for faster adjustment of individual digits.
5. Confirm Value: അമർത്തുക സെറ്റ് again to confirm the new value and return to the parameter code display.
6. ക്രമീകരണ മോഡിൽ നിന്ന് പുറത്തുകടക്കുക: To exit the setting mode, either scroll to an 'End' or 'Exit' parameter, or typically, press and hold the സെറ്റ് button again for a few seconds, or wait for a timeout.

Common parameters to configure include: Input signal type, scaling (min/max range), decimal point position, alarm high/low thresholds (AL1, AL2), alarm hysteresis, and relay action (e.g., normally open/closed).

6. പരിപാലനം

• വൃത്തിയാക്കൽ: Keep the meter's display and casing clean. Use a soft, dry cloth. For stubborn dirt, a slightly damp cloth with mild detergent can be used, but ensure no liquid enters the device. Do not use abrasive cleaners or solvents.
• പരിസ്ഥിതി വ്യവസ്ഥകൾ: Ensure the meter is operated within its specified temperature and humidity ranges. Avoid direct sunlight, excessive dust, corrosive gases, and strong vibrations.
• കണക്ഷൻ പരിശോധനകൾ: Periodically inspect wiring connections for tightness and signs of corrosion. Loose connections can lead to inaccurate readings or intermittent operation.
• കാലിബ്രേഷൻ: While the meter is factory calibrated, if precise accuracy is critical and you suspect drift, professional recalibration may be necessary.

7. പ്രശ്‌നപരിഹാരം

7.1 ഉപയോക്തൃ നുറുങ്ങുകൾ

• Always double-check wiring against the diagram before applying power to prevent damage.
• When configuring parameters, make small adjustments and test the system to ensure desired behavior.
• For critical applications, consider implementing redundant alarm systems or regular functional checks.
