4.2. Wiring Diagram (EAMT1-M1 Example)

Refer to the diagram below for typical wiring connections. Ensure all connections are secure and comply with local electrical codes.

Wiring diagram for the EAMT1-M1 time relay, showing connections for L, N, Trigger, and a lamp càrrega.
Figure 4: Wiring diagram for EAMT1-M1. Note: 15-18 are normally open, 15-16 are normally closed. If the working mode is set to E mode, the trigger terminal closes. After the trigger terminal is closed, the relay operates. 15-18 is closed, 15-16 is disconnected. After the trigger terminal is disconnected, it begins to delay. After the delay time, the relay will reset, 15-18 will be disconnected and 15-16 will be closed.

4.3. Terminal Descriptions

  • R (Red LED): Output indication.
  • 15, 16, 18: First set of conversion contacts (15-18 Normally Open, 15-16 Normally Closed).
  • 25, 26, 28: Second group of conversion contacts (EAMT1-M2 only).

5. Funcionament

5.1. Setting Delay Time

The time relay features two rotary knobs for setting the delay time:

Knob settings for delay gear (seconds, minutes, hours, days, ON, OFF) and fine adjustment (10%-100%), with delay time calculation examples.
Figure 6: Knob settings and delay time calculation.
  1. Knob 1 (Top): Delay gear setting. Select 's' for seconds, 'm' for minutes, 'h' for hours, 'd' for days. 'ON' for relay action, 'OFF' for relay open (15-18/25-28 open).
  2. Knob 2 (Middle): Fine adjustment of delay time, 10% to 100% adjustable.

Delay Time Calculation: Delay time = Knob 1 setting × Knob 2 percentage.

  • Exampel 1: To set for 5 seconds, set Knob 1 to '10s', Knob 2 to '50%'. Delay time = 10s × 50% = 5s.
  • Exampel 2: To set for 8 minutes, set Knob 1 to '10m', Knob 2 to '80%'. Delay time = 10m × 80% = 8m.

5.2. Selecció de la funció

The bottom knob allows you to select one of the 10 available delay modes (A-J). Refer to the 'Functions Diagram' and descriptions below for details on each mode.

5.3. Descripcions de funcions

A: On Delay (Power On)
Quan l'entrada voltagS'aplica e U, comença el retard de temporització t. Els contactes de relé R canvien d'estat un cop finalitzat el retard. Els contactes R tornen al seu estat de prestatge quan l'entrada voltage U s'elimina. L'interruptor d'activació no s'utilitza en aquesta funció.
B: Interval (Power On)
Quan l'entrada voltagS'aplica e U, els contactes del relé R canvien d'estat immediatament i comença el cicle de temporització. Quan s'ha completat el retard, els contactes tornen a l'estat de prestatge. Quan l'entrada voltage U is removed, contacts will also return to their shelf state. Trigger switch is not used in this function.
C: Repeat Cycle (Starting Off)
Quan l'entrada voltagS'aplica e U, comença el retard t. Quan s'ha completat el retard t, els contactes del relé R canvien d'estat pel retard t. Aquest cicle es repetirà fins a l'entrada voltage U s'elimina. L'interruptor d'activació no s'utilitza en aquesta funció.
D: Repeat Cycle (Starting On)
Quan l'entrada voltagS'aplica e U, els contactes del relé R canvien d'estat immediatament i comença el retard t. Quan s'ha completat el retard t, els contactes tornen al seu estat de prestatge per al retard t. Aquest cicle es repetirà fins a l'entrada voltage U s'elimina. L'interruptor d'activació no s'utilitza en aquesta funció.
E: Off Delay (S Break)
Vol d’entradatage U must be applied continuously. When trigger switch S is closed, relay contacts R change state. When trigger switch S is opened, delay t begins. If trigger switch S is closed before time delay t is complete, then time is reset. When delay t is complete, contacts R return to their shelf state. When trigger switch S is opened, the delay begins again, and relay contacts R remain in their energized state. If input voltage U s'elimina, els contactes de relé R tornen al seu estat de prestatge.
F: Single Shot
En aplicar l'entrada voltage U, el relé està preparat per acceptar el senyal d'activació S. Quan s'aplica el senyal d'activació S, el relé es transfereix en contacte amb R i comença el temps preestablert t. Durant el temps d'espera, el senyal d'activació S s'ignora. El relé es reinicia aplicant l'interruptor S quan el relé no està activat.
G: Single Shot Trailing Edge (Non-Retriggerable)
En aplicar l'entrada voltage U, the relay is ready to accept trigger signal S. Upon application of the trigger signal S, the relay contacts R transfer and the preset time t begins. At the end of the preset time t, the relay contacts R return to their normal condition unless the trigger switch S is opened and closed prior to time out t (before preset time elapses). Continuous cycling of the trigger switch S at a rate faster than the preset time will cause the relay contacts R to remain closed. If input voltage U s'elimina, els contactes de relé R tornen al seu estat de prestatge.
H: On/Off Delay
Vol d’entradatage U s'ha d'aplicar contínuament. Quan l'interruptor d'activació S està tancat, comença el retard t. Quan s'ha completat el retard t, els contactes del relé R canvien d'estat i romanen transferits fins que s'obre l'interruptor S. Si vol d'entradatage U s'elimina, els contactes de relé R tornen al seu estat de prestatge.
I: Latching Relay
Vol d’entradatage U s'ha d'aplicar contínuament. La sortida canvia d'estat amb cada tancament de l'interruptor S. Si vol d'entradatage U s'elimina, els contactes de relé R tornen al seu estat de prestatge.
J: Pulse Generator
En aplicar l'entrada voltage U, a single output pulse of 0.5 seconds is delivered to relay after time delay t. Power must be removed and re-applied to repeat pulse. Trigger switch is not used in this function.

6. Manteniment

  • Neteja: Keep the device clean and free from dust and debris. Use a dry, soft cloth for cleaning. Do not use abrasive cleaners or solvents.
  • Inspecció: Comproveu periòdicament les connexions del cablejat per comprovar si estan ben ajustades i si hi ha signes de desgast o danys.
  • Medi ambient: Assegureu-vos que l'entorn de funcionament estigui dins dels rangs de temperatura i humitat especificats per evitar un funcionament incorrecte.
  • Sense peces reparables per l'usuari: The device contains no user-serviceable parts. Do not attempt to open or repair the unit yourself.

7. Solució De Problemes

If you encounter issues with your EARU Time Relay, consider the following common problems and solutions:

  • Device not powering on (Us LED off):
    - Check the input voltage supply (A1, A2) to ensure it is within the AC/DC 12-240V range.
    - Verify that the power connections are secure.
  • Output not switching (R LED off/incorrectly):
    - Confirm the selected function (A-J) and time settings are correct for your application.
    - Check the trigger input (S) if the selected function requires it.
    - Ensure the load connected to the output contacts (15, 16, 18 or 25, 26, 28) is within the 16A rated current.
  • Temporització inexacta:
    - Re-check the settings of both time adjustment knobs (gear and percentagi).
    - Ensure the power supply is stable and free from significant fluctuations.
  • Funcionament intermitent:
    - Inspect all wiring for loose connections or damaged insulation.
    - Check for electromagnetic interference from nearby equipment.

If the problem persists after checking these points, contact customer support.

8. Consells d'usuari

  • For critical applications, always test the relay's function and timing accuracy before deploying it in a live system.
  • When selecting a time range, choose the smallest range that accommodates your desired delay for better precision.
  • Consider using a separate power supply for the control circuit (A1, A2) and the load circuit if the load is inductive or prone to generating electrical noise.
  • Label your wiring clearly during installation to simplify future maintenance or troubleshooting.
