DIAGNOSTICS, PROTECTION & INSTALLATION |
SERVICE PLANNING |
|
Diagnostics & Protection
If the relay does not operate, verify the 24VDC coil supply, socket wiring and mechanical test function. For contact faults, isolate the load circuits and check continuity, contact loading and signs of arcing or contamination.
Replace the relay if the coil, indicator or contact set is damaged; investigate the connected load before returning repeated failures to service.
|
Installation & Upgrades
Match the DRM570024LT AU / 3ABD00036448 identity, 24VDC coil, four-changeover pinout and socket orientation. Confirm each load category and contact current before wiring.
Insert the relay fully into the matching socket, retain it where required and test the contact sequence with controlled power before normal operation.
