CONZERV EM 3460 SMART DEMAND CONTROLLER: Master Your Energy Demand with Intelligent Control Outputs

The CONZERV EM 3460 is an advanced, solid-state Smart Demand Controller designed to proactively manage and reduce your facility’s peak electricity demand, leading to significant savings on your utility bill. At the heart of its functionality are its versatile and robust control outputs, which automate the process of load management by intelligently connecting to your electrical equipment.

The Power of Control: How the EM 3460 Manages Your Loads

The EM 3460 continuously monitors your facility’s real-time power (kW) consumption. When it predicts that your demand will exceed a pre-set target, it automatically activates its control outputs to strategically shed non-essential loads. This prevents a demand peak, avoids penalty charges from your utility provider, and optimizes your overall energy usage.

Key Features of the EM 3460 Control System

• 8 Fully Configurable Control Outputs: Flexible relay outputs can be assigned to any load or group of loads.

• Multiple Control Modes: Choose from Priority, Cyclic, or Timed shedding strategies for optimal load management.

• Automatic & Manual Operation: Seamlessly switch between fully automatic demand control and manual operator intervention.

• Advanced PLC-like Logic: Program complex interlocks and sequences between outputs for sophisticated automation.

• Intuitive Load Scheduling: Define working and non-working hours with different shed strategies for each period.

Detailed Breakdown of Control Outputs

The CONZERV EM 3460 is equipped with a range of output types to interface with virtually any load in your facility:

1. Relay Outputs (Dry Contact)

• Function: These are the primary outputs for direct load shedding. They act as an automatic switch.

• Configuration: The controller features 8 independent Form C (SPDT – Single Pole Double Throw) relay outputs. This means each output has Normally Open (NO) and Normally Closed (NC) contacts, providing wiring flexibility.

• Rating: Typically rated for 5A, 250VAC, making them robust enough to directly control contactors, motor starters, and automation panels without needing an intermediate relay.

• Primary Use Case: Directly switching off non-critical loads like Air Handling Units (AHUs), Water Heaters, Pumps, Compressors, and Lighting Circuits.

2. Analog Output (Optional)

• Function: Provides a variable 4-20mA or 0-10V DC signal for proportional control.

• Use Case: Ideal for controlling devices that require a modulating signal rather than simple on/off control. Examples include:

  • Generator Set Control: Sending a load increase signal to a generator in a grid-parallel setup.

  • Variable Frequency Drives (VFDs): Gradually reducing the speed (and thus power) of a motor instead of shutting it off completely.

  • Process Control Systems: Integrating with a larger Building Management System (BMS) or SCADA.

3. Pulse Output

• Function: Generates a high-frequency pulse signal for energy transaction recording.

• Use Case: Primarily used for connecting to an external kWh meter for sub-metering applications or for verification against the utility meter.

Applications of the EM 3460 Control Outputs

• Automatic Load Shedding: Prioritize and automatically turn off HVAC units, water heaters, and other discretionary loads to cap peak demand.

• Generator Control & Load Sharing: Use the analog output to manage the load on a standby generator set.

• Power Factor Correction Control: Interface with Automatic Power Factor Correction (APFC) panels.

• Industrial Process Automation: Integrate into production lines to manage large machinery start-ups and sequences.

• Building Management System (BMS) Integration: Relay status and receive commands for centralized control.
