Installation Instructions Issue Date September 16, 2014 MS-TDR Time Delay Relay Module Installation Instructions Applications VMA and PCV 1615, 1630, and 1832 Series Controllers are susceptible to a power circuit failure when power is interrupted for a duration between 175 and 225 milliseconds. The MS-TDR-0 and MS-TDR-1 are inline solutions that address this problem. The problem prevents the device from resuming operation after a certain brief duration of power loss. On devices with date codes earlier than RY11420, the MS-TDR guarantees a minimum off time of AC power in order to filter this period of intolerance. The MS-TDR-0 mounts on a single controller. The MS-TDR-1 mounts on a transformer that feeds multiple controllers. Both devices are rated for 100 VA, which is the maximum output of a Class 2 24 VAC transformer. They are suitable for installation on the 24 VAC side of any Class 2 24 VAC transformer. North American Emissions Compliance United States This equipment has been tested and found to comply with the limits for a Class A digital device pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when this equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area may cause harmful interference, in which case the users will be required to correct the interference at their own expense. Canada This Class (A) digital apparatus meets all the requirements of the Canadian Interference-Causing Equipment Regulations. Cet appareil numérique de la Classe (A) respecte toutes les exigences du Règlement sur le matériel rouilleur du Canada. Installation Use the following guidelines when installing the MS-TDR: • Transport the MS-TDR in its original container to minimize vibration and shock damage. • Do not drop the MS-TDR or subject it to physical shock. Parts Included • One MS-TDR Time Delay Relay Module • One installation instruction sheet • Wire nuts (MS-TDR-1 only) Mounting A 1/4-in. thick adhesive foam pad on the bottom of the MS-TDR allows it to mount on a convenient surface. Location Considerations The MS-TDR-0 is intended to mount on the side of a controller. The MS-TDR-1 can mount on the wall of a panel or another low-voltage surface. Wire the MS-TDR-1 before using the adhesive pad to mount it. Wiring WARNING: Risk of Electric Shock. Disconnect power supply before making electrical connections to avoid electric shock. MISE EN GARDE : Risque de décharge électrique: Débrancher l'alimentation avant de réaliser tout raccordement électrique afin d'éviter tout risque de décharge électrique. !© 2014 Johnson Controls, Inc. 1 Part No. 24-10143-667, Rev. A www.johnsoncontrols.com CAUTION: Risk of Property Damage. Do not apply power to the system before checking all wiring connections. Short circuited or improperly connected wires may result in permanent damage to the equipment. MISE EN GARDE : Risque de dégâts matériels. Ne pas mettre le système sous tension avant d'avoir vérifié tous les raccords de câblage. Des fils formant un court-circuit ou connectés de façon incorrecte risquent d'endommager irrémédiablement l'équipement. Wiring the MS-TDR-0 (Single controller installation) 1. Disconnect the 24 VAC power connector from the controller. 2. Plug the MS-TDR-0 output connector into the controller. 3. Plug the existing 24 VAC power connector into the MS-TDR-0 module. 4. Activate the 24 VAC supply, and verify the connected controller operates. 5. Remove the cover from the adhesive foam pad. 6. Mount the MS-TDR-0 module on the side of the controller. The sticker displaying the product code number should remain visible. Figure 1: MS-TDR-0 Figure 2: MS-TDR-0 Installation Wiring the MS-TDR-1 (Multiple controller installation) 1. Ensure that incoming power is removed from the transformer. 2. Cut or disconnect the existing 24 VAC hot and common wires near the transformer, leaving enough wire (at least 6 in.) to connect to the MS-TDR-1 and allow for mounting. 3. Use the supplied wire nuts, or screw into available terminal blocks to connect the MS-TDR-1 Orange (hot) and Brown (common) input wires to the 24 VAC hot and common wires coming from the transformer. 4. Use the supplied wire nuts, or screw into available terminal blocks to connect the MS-TDR-1 Orange (hot) and Yellow (switched common) output wires to the existing 24 VAC controller wiring. 5. Check wiring connections, reconnect power to the transformer, and verify that the controllers are powered. 6. Remove the cover from the adhesive foam pad. 7. Mount the MS-TDR-1 on an open surface. The sticker displaying the product code number should remain visible.

The MS-TDR detects incoming voltage. When the voltage is within an acceptable range for the connected controller, the MS-TDR pauses for 400 ms before enabling the controller. If the input voltage decreases more than 40%, the MS-TDR disables output power until 400 ms after input voltage is restored. Troubleshooting If the MS-TDR-0 is first plugged into 24VAC power, and then plugged into the controller, the controller might go into power lockout mode. If the MS-TDR-0 activates, but the connected controller does not operate, use the following steps: 1. Disconnect power from the MS-TDR-0. 2. Wait 45 seconds, and then reapply power. If the MS-TDR fails to provide power to the connected controller, ensure proper input and output connections. Repair Information If the MS-TDR Time Delay Relay Module fails to operate within its specifications, replace the unit. For a replacement module, contact the nearest Johnson Controls® representative.
