The Gutor Electronics 062.8217, identified by the model EGR 1.1, is a high-precision industrial voltage monitoring relay. Manufactured by Gutor Electronics (a subsidiary of Schneider Electric specialized in high-end UPS and power conversion systems), the EGR 1.1 is engineered for critical power infrastructure. It serves as a protective watchdog, continuously monitoring AC or DC voltage levels to ensure they remain within safe operational windows, thereby protecting downstream sensitive electronics from under-voltage or over-voltage transients.

Technical Description & Parameters

The EGR 1.1 utilizes a solid-state sensing circuit to provide high accuracy and repeatable trip points, far exceeding the performance of traditional electromagnetic voltage sensors.

• Model Number: 062.8217 (EGR 1.1)
• Relay Type: Voltage Monitoring / Undervoltage & Overvoltage Relay.
• Monitoring Range: Adjustable via front-panel potentiometers (refer to specific nameplate for VAC/VDC range).
• Output Contacts: Typically 1 or 2 Changeover (CO) dry contacts.
• Hysteresis: Built-in adjustable differential to prevent relay “chatter” near the set-point.
• Time Delay: Adjustable trip delay (typically 0.1s to 5s) to ride through momentary sags.
• Mounting: Standard 35mm DIN rail or specialized Gutor system rack mounting.
• Enclosure: Industrial-grade polycarbonate housing (IP20).

 

Product Technical Description

The EGR 1.1 is a “window” comparator relay. It monitors the input voltage against a calibrated reference. If the voltage drifts outside the programmed high or low limits, the internal timing circuit begins its countdown. If the fault persists beyond the set delay, the output relay de-energizes (fail-safe operation), signaling a fault to the master control system or tripping a circuit breaker. Its compact design allows it to be integrated directly into Gutor UPS cabinets or standalone industrial control panels.

 

Product Datasheet Essentials

The “062.8217” series is known for its high dielectric strength and resistance to electromagnetic interference (EMI), common in heavy industrial environments. It features high-visibility LED indicators for “Normal,” “Fault,” and “Relay Active” statuses. The unit is designed for 24/7 continuous operation with a projected lifespan exceeding 15 years in climate-controlled environments. It complies with international standards for electrical safety and vibration resistance, ensuring it can withstand the mechanical rigors of offshore or transportable power modules.

Application Fields

The EGR 1.1 is a staple in high-availability power systems:

• Industrial UPS Systems: Monitoring battery bus voltage and inverter output stability.
• Power Plants: Protecting auxiliary control circuits from grid voltage fluctuations.
• Oil & Gas: Ensuring stable power for emergency shutdown (ESD) and fire & gas systems.
• Data Centers: Critical voltage monitoring for high-density server racks.

 

Product Usage Instructions

1. Installation: Clip the EGR 1.1 onto a standard DIN rail. Ensure there is sufficient clearance for wiring the terminal blocks.
2. Wiring: Connect the voltage source to the sensing terminals (observe polarity for DC applications). Wire the output contacts into your control or alarm loop.
3. Calibration: Using a calibrated voltmeter and a variable power source, adjust the “Low” and “High” pots until the relay trips at the desired thresholds.
4. Delay Setting: Adjust the “Time” pot to filter out nuisance trips caused by heavy motor starts or minor grid switching.
5. Functional Test: Briefly lower or raise the input voltage beyond the set-points to verify that the relay operates and the LED indicators change state correctly.

 

Common Questions & Answers (Q&A)

Q: Can the EGR 1.1 be used to monitor both AC and DC voltages? A: Most EGR 1.1 modules are hardware-specific for either AC or DC. Verify the “062.XXXX” number and nameplate markings before applying power to ensure compatibility.

Q: What is “Fail-Safe” operation in this relay? A: In a fail-safe configuration, the relay remains energized during “Normal” conditions. If the voltage fails OR if the relay itself loses power, the contacts will drop out, ensuring a “Fault” is always detected.

Q: Is there a modern digital replacement for the EGR 1.1? A: While Schneider Electric offers modern numerical relays (like the Zelio or Easergy series), many Gutor UPS systems require the original EGR 1.1 to maintain factory certifications and fitment within existing racks.
