Functions and Operation
Ordering Code Explanation
The ordering code structure allows for specific configuration of the relays. For example, for a Series 13, YESLY multifunction relay with Bluetooth, 2Z/6A, and 110-230V AC supply, the code is 13.21.8.230.B000.
Function Descriptions
The relays offer various functions, including:
- Monostable (RM): Output contact closes when a button is pressed and opens when released.
- Bistable: Each press of a button alternately closes and opens the output contact.
- Call Relay with Confirmation: A call is initiated by pressing a button (S), closing contacts 11-14. Confirmation is received by pressing button (R). Contacts 11-14 open when (R) is pressed, provided (S) is not active.
- Impulse-Controlled Relay/Switch (RI): Each button press alternately closes and opens the output contact.
- Time-Delayed Return with Premature Release (IT): Pressing a button closes the output contact. Releasing it starts a delay timer (e.g., 10 min). The output can be prematurely released by pressing the button again.
- Staircase Timer Functions (BE, ME, BP, MP): These functions manage lighting control with various timing and warning features, including automatic shut-off after a set period and pre-warning signals.
- YESLY Specific Functions (e.g., TP, VB, CP): These include control for blinds/shutters, bathroom lighting/fan combinations, and doorbell/lighting circuits.
Function Switching for Type 13.91: The function can be switched between Impulse-Controlled (RI) and Time-Delayed (IT) modes by specific button press sequences during power-up.
Connection Diagrams
Detailed wiring diagrams are provided for various relay types, illustrating connections for different functions and wiring configurations (e.g., 3-wire, 4-wire, button to Line/Neutral). These diagrams show how to connect buttons, loads, and power supply to achieve the desired relay functionality.
Example Diagram Descriptions:
- Type 13.01: Shows bistable operation (button B1-B2) and monostable operation (button B2-B3), with LED status indication.
- Type 13.11/13.12: Illustrates call relay functions with 'Set' (S) and 'Reset' (R) buttons.
- Type 13.61 Series: Depicts 3-wire and 4-wire connections for central shut-off and parallel switching configurations.
- Type 13.81/13.91: Shows 3-wire and 4-wire connections for impulse-controlled and time-delayed functions.
- YESLY Series (13.21, 13.22, 13.S2): Includes diagrams for blind control, bathroom lighting/fan, doorbell/lighting, and general wiring for 2, 3, and 4-wire setups.
Dimensions
Detailed dimensional drawings are provided for each relay type, showing overall dimensions, mounting details (DIN rail, flush-mount), and terminal layouts. These are crucial for installation planning.
Accessories
Finder offers various accessories to complement the relays:
- Panel Adapters: For mounting relays onto panels (e.g., for 35 mm or 17.5 mm width relays).
- Labeling Matrix: For clear identification of relay functions and connections.
- Phase/Neutral Wire Converter: For retrofitting existing installations where buttons only have a phase connection.
- DIN Rail Adapters: For mounting relays into distribution cabinets.
