Indledning
This manual provides essential information for the safe and efficient installation, operation, and maintenance of the Schneider Electric Harmony RE17R Timing Relay. This dual-function timing relay offers precise control over operations, ensuring devices and circuits function in a coordinated manner. It is designed for integration into hard-wired logic schematics and is suitable for various industrial automation, HVAC systems, and other applications requiring precise timing control.
The RE17R relay features a compact 17.5mm width, allowing for flexible DIN rail installation, and offers simple, precise settings via rotary trimmers. It includes a diagnostic button for quick circuit checks and supports both on-delay and pause timing functions.
Sikkerhedsoplysninger
Overhold altid følgende sikkerhedsforanstaltninger for at forhindre personskade eller skade på udstyret:
- Installation og vedligeholdelse bør kun udføres af kvalificeret personale.
- Disconnect all power before working on the device or connected circuits.
- Sørg for korrekt jording for at forhindre elektrisk stød.
- Kontroller, at forsyningen voltage and current ratings match the device specifications.
- Brug ikke apparatet, hvis det er beskadiget eller ikke fungerer korrekt.
Opsætning og installation
The Harmony RE17R timing relay is designed for easy installation on a DIN rail.
Montering
The relay's slim 17.5mm form-factor allows it to be mounted on a standard DIN rail, occupying the same space as a modular 1-pole DIN device. Ensure the DIN rail is securely fastened in a suitable enclosure.

Ledningsføring
The relay supports both screw and spring terminals for adaptable wiring. Refer to the terminal markings on the device for correct connections.
- Power Supply (A1, A2): Connect the appropriate 24 V DC or 24-240 V AC/DC power supply to terminals A1 and A2.
- Control Input (Y1): For specific timing functions (e.g., pause, summation), connect the control signal to terminal Y1.
- Output Contacts (15, 16, 18): The relay features 1 changeover contact SPDT (Single Pole Double Throw).
- Terminal 15: Fælles kontakt
- Terminal 16: Normalt lukket (NC) kontakt
- Terminal 18: Normalt åben (NO) kontakt

Betjeningsvejledning
The Harmony RE17R offers dual timing functions and precise time setting capabilities.
Tidsindstilling
The timing relay can be set for delays ranging from 0.1 seconds to 100 hours using the rotary trimmers on the front panel. The sealable cover helps secure the settings once configured.
- Valg af tidsområde: Use the upper rotary switch to select the desired time range (e.g., 0.1s-1s, 1s-10s, 1h-10h, 10h-100h).
- Justering af tidsværdi: Brug den nederste drejeknap til at finjustere den specifikke tidsværdi inden for det valgte område.

Diagnostisk knap
An instant diagnostic button is built into the device. Pressing this button allows for quick checks of downstream circuits, which can significantly reduce troubleshooting time during installation or maintenance.
Dobbelt funktionalitet
The RE17R supports dual functions, including on-delay and pause timing, as well as summation control signals. Consult the specific wiring diagrams for your application to utilize these advanced features.
Opretholdelse
The Schneider Electric Harmony RE17R Timing Relay is designed for reliable operation with minimal maintenance. However, periodic checks can ensure optimal performance and longevity.
- Visuel inspektion: Regularly inspect the relay for any signs of physical damage, discoloration, or loose connections.
- Terminaltæthed: Periodically check that all terminal connections are secure. Loose connections can lead to overheating or intermittent operation.
- Rensning: If necessary, gently clean the exterior of the relay with a dry, soft cloth. Do not use abrasive cleaners or solvents.
- Miljøforhold: Sørg for, at driftsmiljøet forbliver inden for de angivne temperatur- og fugtighedsområder for at forhindre for tidlig fejl.
Afbryd altid strømmen, før du udfører vedligeholdelsesarbejde.
Fejlfinding
If the Harmony RE17R timing relay is not functioning as expected, consider the following common issues and solutions:
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Relay does not energize | No power supply; incorrect wiring; faulty relay | Check power connections (A1, A2); verify supply voltage; inspect wiring for errors; test relay with known good power source. |
| Incorrect timing delay | Incorrect time range or value setting; control signal issue | Adjust rotary trimmers to the desired time range and value; verify control signal (Y1) is applied correctly. |
| Output contacts not switching | Overload; faulty contacts; incorrect load wiring | Check load current against 8A rating; verify wiring to contacts (15, 16, 18); use diagnostic button to check downstream circuit. |
| Diagnostic button no response | Internal fault; no power to relay | Ensure relay is powered; if power is present and button still unresponsive, the unit may require replacement. |
If problems persist after attempting these solutions, contact Schneider Electric technical support for further assistance.
