1 Install llation Instruction ons Document No Rev. 2, January, 1999 Heat Pump Coller Multi-Stage Produ oduct Description These instructions explain how to field install (pages 1 and 2) or replace (pages 2 through 4) a Heat Pump Coller Multi-Stage (for multiple compressor heat pump applications). Produ oduct Numbe ber Shipping carton includes a coller assembly (coller board and cover), a mounting rail, and two self-tapping/drilling screws. NOTE: Keep the coller assembly in its static-proof bag until you install it on the mounting rail. Install llation Con onven ention ons Requ equired ed Too ools Equipment damage or loss of data may occur if the user does not follow procedure as specified. Electro-Static Discharge (ESD) wrist strap Small flat-blade screwdriver Medium flat-blade screwdriver Medium-duty electric drill 1/4 in. (6.35 mm) hex nut bit Portable Operator s Terminal with Coller Interface Software Rev. 2.0 or higher (required for coller replacement only) Additional tools needed if not using self-tapping option: 1/4 in. (6.35 mm) hex nut driver 1/8 in. (3 mm) bit Prerequ equisi isites Room temperature sensor installed (optional) A source of 24 Vac Class 2 power available Supply power to the unit is OFF If required, coller enclosure installed Expe pected ed Install llation Time New coller installation 10 Minutes Replacement (old coller has 6 Minutes removable terminal blocks) Replacement (old coller does not 16 Minutes have removable terminal blocks) NOTE: You may require additional time for database work at the field panel. New Install llation Instr truction ons NOTE: These steps only refer to new installations. For replacement instructions, refer to pages 2 through 4. The following tasks can be performed by the electrician: 1. Using the mounting rail as a template (re 1), mark the location for the two screw holes where you will install the coller assembly. 2. Do one of the following: If using the self-tapp pping screws: Using the drill and the hex nut bit, fasten the mounting rail with the screws. (Screws do not require starter holes.) If not using the self-tapp pping screws: Drill two 1/8 in. (3 mm) pilot holes for the screws. Align the mounting rail with the holes. Using the hex nut driver, fasten the mounting rail with the #6 or #8 screws. 3. Place the ESD wrist strap on your wrist and attach it to a good earth ground. 1 of 8

Connect the Local Area Network () trunk (re 3). Do not connect an earth ground to the Shield (S) terminal. 6. Connect the point wiring for the appropriate application. Refer to res 5 through 6. The Coller s Digital Outputs (DOs) col 24 Vac loads only. The maximum rating is 12 VA for each DO. For higher VA requirements, 110 or 220 Vac requirements, separate transformers used to power the load, or DC power requirements, use an interposing 220 V 4-relay module (TEC Relay Module P/N ). NOTE: The 24 Vac H terminal is switched through a TRIAC to the NO terminations when the associated DO is energized. 7. Plug the Room Temperature Sensor cable into the RTS port on the coller board. Refer to re Connect the power trunk as shown in re 4. DO NOT apply power to the coller. The installation is complete. Rep eplac acemen ent Instr truction ons Replacement of a TEC requires you to record, re-enter, or update the initial point values of the coller you are replacing. These are the points marked with an asterisk (*) on the Coller Interface Software (CIS) display. NOTE: CIS Rev. 2.0 or higher is required for coller replacement. NOTE: Each DO provides a Normally Open (NO) and a Common (C) terminal. Terminate both connections of a 24 Vac load directly to the coller board. Actuators use 2 DOs and require 3 connections. 2 of 8

3 The following tasks can be performed by the system specialist: 1. Place the ESD wrist strap on your wrist and attach it to a good earth ground. 2. Before disconnecting the old coller, do one of the following: NOTE: If the new coller has a newer firmware revision than the old coller, then skip to the third bullet. If the old coller communicates with the field panel, then update the coller initial values at the field panel. If the old coller does not communicate with the field panel, but communicates with the CIS, or if the coller is stand-alone, then record the initial values (those marked with an asterisk (*) on the CIS display). Record these values in Table 1 at the end of these instructions. If the old coller is not communicating at all, or if the coller you are installing has a newer firmware revision than the old coller, then while at the field panel, follow these steps: a. Obtain a field panel Point Definition Report for the LCTLR point. Record the values in Table 1. b. View the initial value block. (This information is valid only since the last update was made). Record the values in Table 1. c. Delete the LCTLR point from the field panel. 3. Replace the old coller as follows: The following tasks can be performed by the electrician: a. Remove power from the coller. b. If the old coller has the RTS plug between the trunk and point terminations, then disconnect the wires from the power trunk terminal block. If the old coller has the RTS plug on the opposite end of the board from the power trunk terminal block, then remove the power trunk terminal block. c. Remove, in order, the coller s: trunk terminal block point wiring room temperature sensor d. Remove the old coller assembly from the mounting rail. e. Carefully remove the new coller assembly from the anti-static bag. Center it over the mounting rail and snap it securely into place. f. If the old coller has the RTS plug between the trunk and point terminations, then remove all terminal blocks (except the power trunk) from the new coller. If the old coller has the RTS plug on the opposite end of the board from the power trunk terminal block, then remove all terminal blocks. g. Plug, in order, the coller s: pre-wired trunk point wiring h. If the old coller has the RTS plug between the trunk and point terminations, then rewire power to the power trunk terminal block. If the old coller has the RTS plug on the opposite end of the board from the power trunk terminal block, then plug the power trunk terminal block from the old coller into the new coller. i. Connect the room temperature sensor. j. Power up the coller. The following tasks can be performed by the system specialist: 4. Set the address and application at the new coller. 5. Based on what you did in Step 2, do one of the following: If you updated the initial values from the old coller at the field panel, then when you set the address and application for the new coller, the field panel will automatically send the initial values down to the new coller. Once this takes place, replacement is complete. 3 of 8

4 If you manually recorded the initial values in the table, then enter them into the new coller. If a field panel is present, then update the coller s initial values. The replacement is complete. If there was no communication at the old coller, or the new coller has a newer firmware revision than the old coller, then enter the initial values into the new coller. At the field panel, add the LCTLR point and update the coller s initial values. The replacement is complete. #8 TAPPING SCREW HOLE 11/64 (4) DIA.
