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.
