02 / DIAGNOSTICS & INSTALLATION
Diagnostics & Protection
Check field voltage, channel status and controller diagnostics to identify open circuits, incorrect commons or delayed signals. Inspect the base contacts before replacing the input unit.
Installation & Upgrades
Label all sixteen conductors, preserve common-potential grouping and set the documented input delay. Verify controller mapping and interlock logic channel by channel after installation.
