മുന്നറിയിപ്പ്: വൈദ്യുതാഘാത അപകടം. ഇൻസ്റ്റാളേഷനും അറ്റകുറ്റപ്പണികളും യോഗ്യതയുള്ള ഉദ്യോഗസ്ഥർ മാത്രമേ നടത്താവൂ.

• Always disconnect power from both normal and standby sources before installation, inspection, or maintenance.
• എല്ലാ വയറിംഗ് കണക്ഷനുകളും സുരക്ഷിതമാണെന്നും പ്രാദേശിക ഇലക്ട്രിക്കൽ കോഡുകൾ പാലിക്കുന്നുണ്ടെന്നും ഉറപ്പാക്കുക.
• സ്വിച്ച് കേടായതായി തോന്നിയാൽ അത് പ്രവർത്തിപ്പിക്കരുത്.
• The maximum surrounding temperature shall not exceed 40℃, the minimum shall not be lower than -5℃, and the average temperature within 24 hours shall not be higher than 35℃.
• The altitude of the installation site should not be higher than 2000m.
• When the maximum temperature reaches 40℃, the relative humidity of the installation site should not exceed 50%. At lower temperatures, higher humidity is permissible (e.g., 90% at 25℃). Special measures may be required to address occasional condensation.

3. ഉൽപ്പന്ന സവിശേഷതകൾ

5. സജ്ജീകരണവും ഇൻസ്റ്റാളേഷനും

Before installation, carefully inspect the ATS for any damage. Ensure the operating handle moves freely to confirm the flexibility of the drive mechanism. Test the generation and disconnection conditions for each stage of load for both normal and standby power sources.

5.1 മൗണ്ടിംഗ്

The ATS is designed for standard 35mm DIN rail mounting. Securely attach the switch to the DIN rail in your PZ30 distribution box or other suitable enclosure.

6. പ്രവർത്തന നിർദ്ദേശങ്ങൾ

The Automatic Transfer Switch is designed to provide continuous power by automatically switching between a normal power supply and a backup power supply.

6.1 ഓട്ടോമാറ്റിക് മോഡ്

In automatic mode, the switch continuously monitors the normal power supply. If the normal power supply becomes abnormal (e.g., power outage), the switch will automatically transfer the load to the standby power supply within milliseconds. Once the normal power supply is restored, the switch will automatically revert the load back to the normal power supply.

6.2 മാനുവൽ മോഡ്

The switch can also be operated manually using the operating handle. This allows for manual selection of the power source when required, overriding the automatic function. Ensure the power is disconnected before manually switching if safety protocols require it.

7. പരിപാലനം

Regular inspection of the Automatic Transfer Switch is recommended to ensure optimal performance and safety.

• എല്ലാ വയറിംഗ് കണക്ഷനുകളുടെയും ഇറുകിയതയ്ക്കും നാശത്തിന്റെ ലക്ഷണങ്ങൾക്കുമായി ഇടയ്ക്കിടെ പരിശോധിക്കുക.
• Inspect the switch for any physical damage or signs of overheating.
• Ensure the operating handle moves freely and without obstruction.
• Keep the switch clean and free from dust and debris.

8. പ്രശ്‌നപരിഹാരം

If the Automatic Transfer Switch is not functioning as expected, consider the following:

• No Power Transfer: Verify that both normal and standby power sources are active and correctly connected. Check for tripped circuit breakers or blown fuses.
• ഇടയ്ക്കിടെയുള്ള പ്രവർത്തനം: Inspect all wiring for loose connections. Ensure the environmental conditions (temperature, humidity) are within the specified limits.
• Switch Not Engaging: Check the manual operating handle for any obstructions. If in automatic mode, ensure control signals are correctly received.

If issues persist after basic troubleshooting, contact a qualified electrician or the manufacturer for assistance.
