Installation & Maintenance Insights
Because the IC695ALG626-EA is a single-slot module in the RX3i backplane, rail-mounting is straightforward. But a few field tricks help:
- Always power the backplane off before inserting or removing the module to avoid spiking neighboring modules.
- Use shielded twisted-pair wiring for voltage or current inputs; tie shields correctly to chassis ground — improper shielding is the leading cause of analog noise.
- Start with a conservative filter (e.g. 8 Hz or 12 Hz) if your signals are reasonably slow, then relax to 40 Hz or 200 Hz only if response speed is needed.
- Periodically check for terminal block corrosion or looseness. The TB (terminal block) LED on the module is handy — it goes red if the block is disconnected.
- Recalibrate every 12 months (typical) to maintain the ±0.1 % class accuracy over time.
- During firmware upgrades or system rebuilds, prevent inadvertent changes to the input scaling or HART settings. Always back up configuration.
A small tip: when pulling channel data, stagger scan acquisition cycles in your logic so you don’t overburden system bandwidth. The analog scan time depends on number of acquisition cycles, filter settings, and whether HART is active.
