Phoenix Contact ELR H5-IES-SC-24DC/500AC-9 29 004 21 Hybrid Motorstarter/Reversing
 |
ELR H5‑IES‑SC‑24DC/500AC‑9 is a hybrid motor starter that replaces a conventional reversing contactor for three‑phase AC motors up to 500 V and 9 A, using 24 V DC control with adjustable overload shutdown and SIL 3/PL e emergency stop. Common failure points include insulation breakdown between the internal contacts, tripping of the overload protection due to overheating or miscalibration, and failure of the emergency stop circuit to reset. First‑check diagnostics should verify the 24 V DC supply voltage and continuity, inspect the motor wiring and contactor contacts for wear or burn marks, and review any fault codes displayed on the unit’s diagnostic display or external PLC interface.[oss-gpt-20b] |
