Verify that your active chassis slot is populated with a 3511 or 3515 pulse input module, as mismatching the terminal board backplane connector can cause hardware diagnostic faults inside the TriStation 1131 software environment.\u003c\/p\u003e\n\n\u003ch4 style=\"color: #2b6cb0; margin-top: 1rem; margin-bottom: 0.5rem;\"\u003eApplication Pitfalls \u0026amp; Engineering Notes\u003c\/h4\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003ePulse sensors, particularly passive magnetic pickups (MPUs), generate low-voltage signals at low speeds. The Triconex 3002 relies on pristine field-side wiring practices to avoid signal attenuation. Ensure that signal lines are not routed parallel to high-power motor control center (MCC) feeds or variable frequency drive (VFD) output cables, which can introduce crosstalk and result in spurious overspeed trips.\u003c\/p\u003e\n\n\u003ch4 style=\"color: #2b6cb0; margin-top: 1rem; margin-bottom: 0.5rem;\"\u003eCommissioning \u0026amp; Wiring Tips\u003c\/h4\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003eAlways terminate the field-side cable shield at the designated ground bar on the 3002 terminal board. The sensor end of the shield must be left floating (insulated) to prevent ground loops. During commissioning, use an oscilloscope at the terminal board test points to verify a clean, symmetric sinusoidal waveform from passive sensors, ensuring the peak-to-peak voltage exceeds the threshold configuration set in the controller logic.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #1a365d; margin-top: 1.5rem; margin-bottom: 0.5rem;\"\u003eInstallation Guidelines\u003c\/h3\u003e\n\u003cdiv style=\"background-color: #fff5f5; border-left: 4px solid #c53030; padding: 1rem; margin-bottom: 1.5rem;\"\u003e\n  \u003cstrong style=\"color: #9b2c2c; display: block; margin-bottom: 0.5rem;\"\u003eCRITICAL WARNING:\u003c\/strong\u003e\n  \u003cspan style=\"color: #9b2c2c;\"\u003eBefore installing or servicing the Triconex 3002 terminal board, ensure that the safety system chassis is fully de-energized or that the respective loop has been placed in a secure manual bypass.
