Quality Control Process
We don’t just plug and play. Every undergoes signal injection testing. I verify all 8 universal inputs using precision voltage sources and resistance boxes. Triac outputs get load-bank validation to confirm switching integrity. Firmware checksums are verified against factory baselines. FLASH EPROM integrity is checked for write cycles. Units ship in anti-static shielding.
Replacement Pitfall Guide
❗ Verify Input Jumper Settings: Universal inputs aren’t always auto-sensing. Check physical jumpers or software config for NTC vs. 0-10V. Wrong setting burns cards.
❗ Triac Inrush Limits: Don’t drive magnetic contactors directly. The 6 digital outputs are Triacs, not relays. Use interposing relays for inductive loads.
❗ Ground Loop Isolation: This shares common ground internally. Daisy-chaining shields creates noise. Star-ground your sensor cables at the panel.
❗ Power Supply Sag: 24VAC transformers often sag under load. Measure voltage at the terminal during startup. Brownouts corrupt FLASH memory.
Keep these in mind and you’ll cut 90% of rework time.
