4. સલામતી માહિતી

ઉપકરણને ઇજા કે નુકસાન ન થાય તે માટે હંમેશા નીચેની સલામતી સાવચેતીઓનું પાલન કરો:

• સ્થાપન અને જાળવણી ફક્ત લાયક કર્મચારીઓ દ્વારા જ થવી જોઈએ.
• કોઈપણ વાયરિંગ અથવા જાળવણી કરતા પહેલા ખાતરી કરો કે પાવર સપ્લાય ડિસ્કનેક્ટ થઈ ગયો છે.
• ચકાસો કે વોલ્યુમtage and current ratings of the device match your application requirements.
• Do not expose the device to moisture, extreme temperatures, or corrosive environments.
• Use appropriate wire gauges and ensure all connections are secure.

5. સ્થાપન અને સેટઅપ

5.1. ભૌતિક સ્થાપન

The Elko CRM-91H-UNI is designed for DIN rail mounting. Securely attach the relay to a standard DIN rail within an appropriate enclosure, ensuring adequate ventilation and clearance for wiring.

5.2. વાયરિંગ જોડાણો

Refer to the wiring diagram provided with your device and the labels on the unit for correct connections. The main terminals are located at the top of the unit.

Figure 1: Front and Top View of Elko CRM-91H-UNI Relay.

This image displays the front and top view of the Elko CRM-91H-UNI relay. On the top, three screw terminals are visible, labeled A1, S, અને A2, for power and control connections. The front panel features the model name 'CRM-91H/UNI', an 'Un' indicator (likely for power), and several rotary switches. Two larger rotary switches are for 'TIME' setting (with multipliers 10/1, 10, 1) and 'FUNC' selection (labeled a-h, 1-9, 10). Small LED indicators are also present. The 'ELKO' brand logo is at the bottom left.

• A1, A2: Connect the main power supply (12-240 VAC/DC) to these terminals.
• S: This terminal is typically used for a control input or trigger, depending on the selected function.
• આઉટપુટ સંપર્કો: Connect your load to the relay's output contacts (not explicitly labeled in the image but standard for relays). Refer to the product's specific wiring diagram for contact numbering.

6. ઓપરેશન

6.1. કાર્ય પસંદગી

The CRM-91H-UNI offers 10 distinct operating functions. Use the rotary switch labeled 'FUNC' on the front panel to select the desired function. The available functions are typically indicated by letters (a-h) and numbers (1-10) on the switch. Consult the product's detailed function table (usually found in the manufacturer's full datasheet) to understand the behavior of each function (e.g., ON delay, OFF delay, impulse, etc.).

6.2. સમય સેટિંગ

The timing period is set using two rotary controls:

• Time Range Multiplier: The upper rotary switch labeled 'TIME' (with markings like 10/1, 10, 1) selects the time range multiplier (e.g., seconds, minutes, hours, days).
• પોટેન્શિયોમીટર: The lower rotary potentiometer (often marked 0-10 or similar) fine-tunes the time within the selected range. For example, if the range is set to '10s' and the potentiometer to '5', the delay would be 5 seconds.

The total time delay is calculated by multiplying the value set on the potentiometer by the selected time range multiplier.

6.3. સૂચકાંકો

• Un Indicator: This LED (often green) illuminates when the power supply is connected and the unit is operational.
• Output Status Indicator: Another LED (often red) indicates the status of the relay's output contacts (e.g., illuminated when the output is active).

7. જાળવણી

The Elko CRM-91H-UNI relay is designed for long-term, maintenance-free operation under normal conditions. However, periodic checks are recommended:

• સફાઈ: Keep the unit free from dust and debris. Use a soft, dry cloth for cleaning. Do not use liquid cleaners.
• જોડાણો: Periodically inspect wiring connections to ensure they remain tight and free from corrosion.
• પર્યાવરણ: ખાતરી કરો કે કાર્યકારી વાતાવરણ નિર્દિષ્ટ તાપમાન અને ભેજની શ્રેણીમાં રહે છે.

8. મુશ્કેલીનિવારણ

If the relay is not functioning as expected, consider the following:

• No Power (Un indicator off):
  • Check the main power supply to terminals A1 and A2.
  • વોલ્યુમ ચકાસોtage is within the 12-240 VAC/DC range.
  • Inspect wiring for loose connections or breaks.
• Relay Not Activating:
  • Ensure the correct function is selected via the 'FUNC' rotary switch.
  • Verify the time setting is correctly configured and the delay period has elapsed.
  • Check the control input (terminal S) if applicable for the selected function.
  • Confirm the load connected to the output contacts is functioning correctly and within the relay's current rating.
• ખોટો સમય:
  • Re-check the 'TIME' range multiplier and the potentiometer setting.
  • Ensure the selected function corresponds to the desired timing behavior.

If problems persist after checking these points, contact technical support.
