Introduction This manual is intended to guide ETC Service Technicians through the process of upgrading existing Sensor+ rack installations to Sensor3 racks with a CEM3 control module. This manual covers SR+ or HSR+ 6, 12, 24 and 48 permanent installation dimming racks. If you have questions about the retrofit process that are not answered in this manual, please contact ETC Technical Services.
Safety Please note the following safety warnings before use: • Disconnect power from the racks before all maintenance. WARNING: Dimmer racks without an accessible power disconnect device cannot be serviced safely. Before removing dimmer or control modules for service, deenergize main feed to dimmer rack and follow appropriate Lockout/Tagout procedures as described in NFPA Standard 70E.

Section 2 The Retrofit Preparation Step 1: Use the Sensor+ Connect web interface to download and save the current configuration out of the rack for later reference. Instructions on saving your configuration from this interface can be found in any CEM+ Software Release Note or any CEM+ Configuration Manual available for download from the ETC website (www.etcconnect.com). Step 2: Turn off main power to the rack(s).
Attach New Power Harness Step 1: Connect the old power connector to the new power harness adapter found in the kit. The connectors are keyed - the power connectors only fit one way. New Power Harness Step 2: Run the green ground wire from the power harness adapter between the bus bar and the rack wall avoiding any interference with other wires in the rack. Step 3: Carefully route the ground wire to any open terminal in a grounding strip inside the rack.
M a k e C o n n e c t i o n s a n d I ns t a l l t h e N e w B a c k p l a n e Step 1: Remove the 3-pin Phoenix connector that ships attached to the rear of the backplane. It will not be used in this retrofit. Step 2: Verify that the 4-pin Molex caps are in place over the connectors next to where the phoenix connector was attached. Verify 2 Remove Step 3: Bend one arm of the backplane metal in towards the opposite arm (about 30 deg). Step 4: Insert the backplane metal on an angle.
Step 5: Make the power and data connections on the backplane. a: Install the dimmer output ribbon cables. Open the black retaining tabs for each connector until they are at a 45° angle to the backplane. Press the connectors into their respective locations until the tabs lock in place at a 90° angle to the backplane. Make sure the proper side is facing up on each connector and that each connector is fully seated. b: Install the power harness (Look at the pin shapes for proper orientation.
Backplane Settings Upgrade kit backplanes ship from the factory with all DIP switches in the off (down) position. You will have to set the DIP switches on the new backplane to match your rack. You will also have to verify the termination switch settings. Set termination to “Off” (middle position) Set DIP switches a: Set both termination switches to “Off” (middle position) for all racks except the last rack in your system.
Change out the AF Cards (if present) If your rack supports Advanced Features (AF) you will need to replace the AF cards as well. AF cards are located on the right side of the dimmer module slot between the copper neutral busses and the dimming circuitry cards. To replace the AF cards: Step 1: Remove the old AF cards by flipping the white retainer tab on the cards into the down position. Step 2: Pull the old cards out of the slots.
F i n i s h i ng T o u c h e s Step 1: Carefully remove old Sensor+ label from the front of the door and discard. Step 2: Clean the door surface to remove any dirt or old adhesive. Step 3: Apply the new Sensor3 label to the front of the door. Line up the label around the opening for the acrylic in the door and be sure the label is straight. Press and wipe with a piece of cloth or paper towel to make sure the label is flat & smooth and properly adhered to the rack door.
