Dayton Time Delay Relay User Manual

1. Introduction and Overview

This manual provides essential information for the safe and effective operation of your Dayton Time Delay Relay, Model 31EE11. This versatile relay is designed to offer a wide range of timing functions and universal voltage input, making it suitable for various industrial and scientific applications.

The compact unit integrates 10 distinct timing functions and a programmable time range from 0.1 seconds up to 10 days. Its 16A SPDT (Single Pole Double Throw) output contacts are capable of handling most general-purpose loads. The relay features LED indicators for operational status: a green LED illuminates when input voltage is applied, and a red LED blinks during the timing cycle, becoming steady when the output relay is energized. Its 17.5mm enclosure is designed for easy installation onto a 35mm DIN rail, optimizing space and reducing installation time.

4. Installation and Setup

Proper installation is crucial for the reliable operation of the time delay relay. Follow these steps carefully:

1. Mounting:

   The relay is designed for DIN rail mounting. Snap the relay securely onto a standard 35mm DIN rail in your control panel or enclosure. Ensure it is firmly seated to prevent vibration.
2. Wiring Connections:

   Before making any connections, ensure all power to the circuit is disconnected. The relay uses screw clamp terminals for electrical connections. Refer to the diagram below for terminal identification and wiring.

   

   Figure 4.1: Dayton 31EE11 Time Delay Relay Overview. This image displays the Dayton 31EE11 Time Delay Relay, highlighting its compact design and key features. Visible elements include the "Dayton" brand name, model number "31EE11", input voltage range "AC/DC 12-240V", and various certifications (UL Listed, RoHS, CE). The top of the unit features two rotary potentiometers for "TIME" adjustment and "FUNC" (function) selection. The side of the relay provides a detailed diagram illustrating the 10 timing functions (A-J) and their corresponding settings. Wiring terminals are clearly marked: A1 and A2 for coil voltage input, and 15, 16, 18 for the SPDT output contacts. Important specifications such as maximum wire size (14 AWG / 2.5mm²) and screw torque (4.4-7.1 lb-in / 0.5-0.8 N-m) are also printed on the side, along with contact ratings (15A @ 240VAC, 3/4hp @ 240V, 1/3hp @ 120V) and country of manufacture (Made in Czech Republic).

   • Coil Power (A1, A2): Connect your 12-240VAC/DC power supply to terminals A1 and A2.
   • Output Contacts (15, 16, 18):
     • Terminal 15: Common (COM)
     • Terminal 16: Normally Closed (NC)
     • Terminal 18: Normally Open (NO)
     Connect your load circuit to the appropriate output terminals based on your application's requirements (e.g., between 15 and 18 for normally open operation).
   • Wire Specifications: Ensure wire size does not exceed 14 AWG (2.5mm²).
   • Screw Torque: Tighten terminal screws to 4.4-7.1 lb-in (0.5-0.8 N-m) to ensure secure connections and prevent loosening.
3. Function Selection:

   Use the "FUNC" rotary dial on the top of the relay to select one of the 10 available timing functions (A through J). Refer to the function diagram printed on the side of the relay for detailed descriptions of each function's behavior.

4. Time Setting:

   Use the "TIME" rotary dial to set the desired time delay. The dial allows for precise adjustment within the selected time range. The time range itself is typically set by a smaller internal switch or is automatically scaled based on the function selected (refer to the device markings for specific scaling if applicable).

5. Operation

Once installed and configured, the Dayton 31EE11 Time Delay Relay operates automatically based on the selected function and time setting.

• Power On: Apply power to terminals A1 and A2. The green LED will illuminate, indicating that the relay is receiving input voltage.
• Timing Cycle: Depending on the selected function, the red LED will begin to blink during the active timing cycle.
• Output Energized: Once the timing cycle is complete and the output relay is energized, the red LED will become steady. The SPDT contacts (15, 16, 18) will switch their state according to the selected function.
• Function Behavior: Refer to the function diagram on the relay's side for the specific behavior of each timing mode (e.g., On Delay, Off Delay, Flasher).

6. Maintenance

The Dayton 31EE11 Time Delay Relay is designed for long-term, maintenance-free operation under normal conditions.

• Cleaning: If necessary, gently wipe the exterior of the relay with a dry, soft cloth. Do not use abrasive cleaners or solvents.
• No User-Serviceable Parts: The relay contains no user-serviceable parts. Do not attempt to open or repair the unit. Doing so will void the warranty and may cause damage or injury.
• Periodic Inspection: Periodically inspect wiring connections for tightness and signs of wear or corrosion, especially in high-vibration environments.

7. Troubleshooting

If you encounter issues with your time delay relay, refer to the following troubleshooting guide:

If troubleshooting steps do not resolve the issue, contact Dayton customer support or a qualified electrician.
