Country of Origin
This metering equipment was engineered and manufactured by GEC Meters (later part of the GE/Landis+Gyr heritage) in the United Kingdom.
Application Fields
The E42 series is a standard for revenue-grade metering in:
- Industrial Facilities: Monitoring main incoming power for factory units.
- Commercial Buildings: Billing for office complexes and shopping centers.
- Sub-metering: Allocating energy costs in multi-tenant industrial estates.
- Renewable Energy: Measuring export energy from large-scale solar or wind installations.
- Utilities: Serving as the primary billing interface for medium-voltage customers.
Product Usage Instructions
- Safety First: Installation must be performed by a certified electrician. Ensure the main supply is isolated before removing the terminal cover.
- Mounting: Fix the meter to a vertical, vibration-free surface using the provided mounting points.
- Wiring: Follow the terminal diagram located on the inside of the terminal cover. Ensure all screws are tightened to the correct torque to prevent overheating at high current loads.
- Sealing: Once wired and verified, the terminal cover and programming port must be sealed with utility-approved security seals to prevent tampering.
- Reading: Use the front-panel button to cycle through the LCD menu to view kWh, Peak Demand, and current Tariff rates.
Product Technical Description
The E42F4C-HTS211B utilizes solid-state sensing technology to calculate energy consumption. Unlike older induction-disc meters, this electronic unit uses high-precision current transformers and voltage dividers to feed signals into a digital signal processor (DSP). The HTS211B variant is specifically configured with high-torque, stable components and a “Pulse” output feature (S0 interface) for integration into Building Management Systems (BMS). The polyphase design ensures that power is accurately measured even if the loads across the three phases are unbalanced.
Q&A (Common Questions)
Q: What does the “HTS” in the model code stand for? A: HTS typically refers to the specific firmware or feature set package, often including specific tariff capabilities or pulse output configurations required by certain regional utilities.
Q: Can this meter handle 3-wire and 4-wire systems? A: This model is primarily designed for 4-wire (Phase-Neutral) three-phase systems, which is the standard for most commercial LV distributions.
Q: Is there a battery inside the meter? A: Yes, an internal long-life lithium battery maintains the LCD display and clock settings during a power outage, ensuring data is not lost.
Q: Can I use this for remote AMR (Automatic Meter Reading)? A: Yes, the optical port can be used for local reading, and the pulse output can be connected to a remote telemetry unit for automated data collection.
