Setup
1. Mounting
The EAMT1-M1 relay is designed for DIN rail mounting. Securely attach the relay to a standard 35mm DIN rail in an appropriate enclosure.

2. Wiring
Refer to the wiring diagram below for correct connections. Ensure all connections are secure and comply with local electrical codes.
- A1, A2: Supply Voltage (AC/DC 12V-240V). Connect the power supply to these terminals.
- S: Trigger Terminal. This terminal is used for specific functions (e.g., Off Delay, Single Shot).
- 15: Common contact for the output relay.
- 16: Normally Closed (NC) contact.
- 18: Normally Open (NO) contact.

Operating Instructions
The EAMT1-M1 relay features three rotary switches on the front panel for function selection, time range, and time adjustment.

1. Function Selection
Use the middle rotary switch (labeled A-J) to select one of the 10 available time functions:
- A: On Delay (Power on) - The relay energizes after a set delay once power is applied.
- B: Interval (Power on) - The relay energizes immediately upon power application and de-energizes after a set delay.
- C: Repeat Cycle (Starting off) - The relay cycles between OFF and ON states, starting with OFF, with set delays for each state.
- D: Repeat Cycle (Starting on) - The relay cycles between ON and OFF states, starting with ON, with set delays for each state.
- E: Off Delay (S Break) - The relay de-energizes after a set delay once the trigger (S) is removed.
- F: Single Shot - A brief pulse on the trigger (S) causes the relay to energize for a set delay.
- G: Single Shot Trailing Edge (Non-Retriggerable) - The relay energizes for a set delay upon the falling edge of the trigger (S). Subsequent triggers during the delay are ignored.
- H: On/Off Delay - A combination of on-delay and off-delay functions.
- I: Latching relay - The relay changes state with each pulse on the trigger (S).
- J: Pulse generator - Generates continuous pulses with a set ON and OFF time.
2. Time Range Selection
Use the top rotary switch to select the desired time range:
- 10s (0.1s - 10s)
- 1m (0.1m - 1m)
- 10m (0.1m - 10m)
- 1h (0.1h - 1h)
- 10h (0.1h - 10h)
- 1d (0.1d - 1d)
- 10d (0.1d - 10d)
3. Time Adjustment
Use the bottom rotary switch (0-100%) to fine-tune the delay time within the selected range. For example, if the range is 10s and the dial is set to 50%, the delay will be 5 seconds.
4. LED Indicators
- Us (Green LED): Illuminates when power is supplied to the relay.
- R (Red LED): Illuminates when the output relay is energized.
Maintenance
The BAISULI EAMT1-M1 time delay relay is designed for maintenance-free operation under normal conditions.
- Periodically inspect wiring connections for tightness and signs of wear.
- Keep the device clean and free from dust and debris.
- Ensure adequate ventilation around the device to prevent overheating.
- Do not attempt to open or repair the device. Refer to qualified service personnel if a malfunction occurs.
Troubleshooting
If the relay is not functioning as expected, consider the following:
| Problem | Possible Cause | Solution |
|---|---|---|
| Green "Us" LED is off. | No power supply or incorrect wiring to A1/A2. | Check power supply voltage and wiring connections. Ensure voltage is within AC/DC 12V-240V. |
| Red "R" LED does not illuminate or relay does not switch. | Incorrect function selection, time setting, or trigger input (if applicable). Overload on output contacts. | Verify the selected function (A-J) and time range/adjustment. Check trigger input (S) if the function requires it. Ensure load current does not exceed 16A. |
| Relay operates erratically. | Unstable power supply, electrical interference, or faulty unit. | Ensure stable power. Check for sources of electrical noise. If problem persists, the unit may be faulty. |
