Signs of faulty Liquid Level Relay 26NMB1A0A Warrick-Gems Sensors:

Level Control Issues:

• Pumps or alarms activating unexpectedly: This could be due to faulty level detection by the sensor, incorrect settings, or internal relay malfunctions.
• Pumps failing to activate at intended levels: This might indicate a faulty sensor connection, incorrect sensitivity settings, or relay issues.
• Erratic or inconsistent level readings: This could be caused by a faulty sensor, loose connections, or internal component issues.

Relay or Output Problems:

• Relays chattering or buzzing continuously: This suggests potential internal relay damage or wiring issues.
• One or both relays failing to switch: This could point to individual relay failure or problems with the control circuitry.
• Output voltage incorrect or fluctuating: This might indicate internal component failure or power supply issues.

Indicator and Power Issues:

• LED indicators malfunctioning: Dim, flickering, or constantly lit LEDs could signify internal circuit problems.
• Unit not powering on: This could be due to power supply issues, a faulty fuse, or internal component failure.
• Tamper-proof enclosure showing signs of forced entry (if applicable): This could indicate unauthorized access or potential tampering with the control settings.

Additional Observations:

• Unusual noises or vibrations from the unit: This might suggest internal component issues or loose connections.
• Burning smell or smoke emanating from the unit: This is a serious sign and requires immediate shutdown and investigation.

Remember:

• Always consult the manufacturer's instructions and troubleshooting guide for specific steps and safety precautions.
• If you suspect a faulty 26NMB1A0A, immediately shut down the system and disconnect it from power.
• Seek assistance from a qualified electrician or technician for diagnosis and repair.
