Command Relays Installation Instructions
Command Relays Installation Instructions Part No. 24-10345-50, Rev. B CR-01200-0, CR-02400-0 Issued March 31, 2014 Supersedes April 5, 2013 Refer to the QuickLIT website for the most up-to-date version of this document. Applications The CR-01200-0 and CR-02400-0 Command Relays facilitate the starting and stopping of motors. The relays are manufactured for use with the Johnson Controls® Current Switch Device (CSD) Series product. The relays are offered with actuation coil voltages of 24 VAC/VDC and 12 VAC/VDC. Each relay includes a Light-Emitting Diode (LED) status light that indicates the operating status of the relay. ! AVERTISSEMENT : Risque de blessure. Ne pas toucher le CR-02400-0 relay lorsque le relay est sous tension. La surface du relay devient extrêmement chaude durant son utilisation et risque de provoquer des brûlures graves en cas de contact. The relays require an AC or DC power supply to operate, and can be wired to an independent circuit or in conjunction with current switch contacts. IMPORTANT: The Command Relay is intended to provide an input to equipment under normal operating conditions. Where failure or malfunction of the relay could lead to personal injury or property damage to the controlled equipment or other property, additional precautions must be designed into the control system. Incorporate and maintain other devices, such as supervisory or alarm systems or safety or limit controls, intended to warn of or protect against failure or malfunction of the relay. IMPORTANT : Le Command Relay est destiné à transmettre des données entrantes à un équipement dans des conditions normales de fonctionnement. Lorsqu'une défaillance ou un dysfonctionnement du relay risque de provoquer des blessures ou d'endommager l'équipement contrôlé ou un autre équipement, la conception du système de contrôle doit intégrer des dispositifs de protection supplémentaires. Veiller dans ce cas à intégrer de façon permanente d'autres dispositifs, tels que des systèmes de supervision ou d'alarme, ou des dispositifs de sécurité ou de limitation, ayant une fonction d'avertissement ou de protection en cas de défaillance ou de dysfonctionnement du relay. WARNING: Risk of Personal Injury. Do not touch the CR-02400-0 relay while power is applied to the relay. The relay surface is hot during use, and may cause a serious burn upon contact. IMPORTANT: Install the CSD Series Current Devices only on the input side of a variable speed drive. Otherwise excessive wear may occur on the controlled equipment, as well as premature failure of the CSD Series Current Devices. Mounting To mount the command relay: 1. Using a clean, dry cloth, wipe the mounting area on the current switch. 2. Remove the release paper from the adhesive strip on the relay. Avoid touching the exposed adhesive on the relay. 3. Snap the relay into place on the current switch (Figure 1). 4. Press and hold the parts together for 5 to 10 seconds. Command Relays Installation Instructions 1 2. Connect the desired load signal on the terminals marked NO. Relay Relay Figure 1: Mounting the Relay Figure 3: CR-02400-0 Wiring Terminals Wiring ! WARNING: Risk of Electric Shock. Disconnect the power supply before making electrical connections. Contact with components carrying hazardous voltage can cause electric shock and may result in severe personal injury or death. AVERTISSEMENT : Risque de décharge électrique. Débrancher l'alimentation avant de réaliser tout branchement électrique. Tout contact avec des composants conducteurs de tensions dangereuses risque d'entraîner une décharge électrique et de provoquer des blessures graves, voire mortelles. To wire the command relay, follow these steps and see Figure 2: 1. Connect the proper AC or DC voltage for the relay being used to the terminals marked COIL. The coil is not polarity sensitive. 2 FIG:rly_wir FIG:rly_mnt Figure 2: CR-01200-0 Wiring Terminals Command Relays Installation Instructions The relay contacts are Normally Open (N.O.) when no control signal is applied to the COIL terminals. The relay contacts close and the LED illuminates when the proper voltage is applied to the COIL terminals. The relay N.O. terminals remain closed and the LED remains illuminated provided power is maintained on the COIL terminals. Setup and Adjustments The command relay requires no additional setup, adjustments, or commissioning. Repair Information If either the CR-01200-0 or CR-02400-0 Command Relay fails to operate within its specifications, replace the unit. For a replacement relay, contact your nearest Johnson Controls® representative. Troubleshooting See Table 1 for troubleshooting information. Table 1: Troubleshooting Information Problem Action LED does not light, and the relay output does not switch, or relay opens and closes erratically. Verify that the proper voltage control signal is present and that the available current is within the range specified for the relay coil current. See Technical Specifications. LED remains illuminated, but relay contacts open and close properly. Possible LED damage. See Technical Specifications. Relay remains closed, but LED turns on and off properly. Possible relay damage. See Technical Specifications. Technical Specifications CR-01200-0 and CR-02400-0 Command Relays Product Description CR-01200-0: 12 VAC/VDC Single-Pole, Single-Throw (SPST), N.O.
