FAQs
To install, mount the unit on a TH35 DIN rail (TH35-15 or TH35-7.5) in the control panel. Connect the 24 V AC supply to the device’s power terminals and wire the two electrodes to the sensing circuit (0–100 kΩ range). Use screw terminals for secure, vibration-resistant connections and follow standard wiring practices for safety and reliability.
The CM-ENE MIN uses 24 V AC control, with an output of 1 normally open contact. Rated operational currents are AC-12 at 4 A and AC-15 at 3 A (230 V). For DC, Ie is 4 A (DC-12, 24 V) and 2 A (DC-13, 24 V). It supports up to 300 V AC on the output circuit under UL/CSA, with RoHS-compliant construction.
Yes. It is specifically designed for draining monitoring and dry-running protection, using a 0–100 kΩ sensing range across two electrodes to detect low liquid levels and trigger the NO contact to stop or start pumps, thereby preventing pump burnout and reducing maintenance needs.
The unit is UL 508 listed and CE marked, with UKCA compliance and RoHS conformity. It also aligns with CAN/CSA C22.2 No.14, IEC/EN 63000, IEC/EN 61000-6-2, and IEC/EN 61000-6-3, ensuring broad regulatory readiness for global deployment.
By preventing dry-running events, the CM-ENE MIN reduces unscheduled downtime and extends pump life. Its straightforward DIN-rail installation and screw-terminal wiring simplify maintenance, while compatibility with common level sensors minimizes sensor replacement costs and accelerates commissioning in multi-site pump systems.
