Cut the correct size hole into the panel and mount the controller, using its mounting brackets See Chapter Two for details on installation and mount- Ing. If you retrofit the Series SD31 controller into an ex- isting application, you may need to use a Watlow adapter plate to adapt it to the smaller controller size Step 2: Wire the controller. The controller will need to have its power, input and output wiring installed, The wiring depends on the spe cific model number of the Series sd31 controller. The dimension illustrations in Chapter Two show the loca tion of the model number use the model number to de termine which wiring diagrams to follow for your con troller. See Chapter two for wiring details Step 3: Configure the Setup Page. Setup Page parameters tell the controller what in put and output devices are wired to the controller and how the controller should function Without the proper Setup Page settings, the controller will not operate or could operate erratically. Since these settings require detailed knowledge on the wiring and operation of the equipment, the oem or the designer normally pro grams these parameters. Some settings, such as the baud rate or controller address, are Setup Page param ctors, but would probably be set by the end uscr Watlow series sd3 1 Chapter 1 Overview △ Caution: Follow the installa- tion procedure exactly to 2 guarantee a proper IP65/NE Install and wire MA 4X seal.

While pressing the bezel firmly against the panel, slide the mounting bracket over the back of the controller 4. If the installation does not require an IP65/NEMA 4X seal, slide the bracket up to the back of the panel enough to eliminate the spacing between the gas- ket and the panel For an IP65/NEMA 4X seal, use your thumb to lock the tabs into place while pressing the controller from side to side. Dont be afraid to apply enough pres sure to properly install the controller. If you can move the controller back and forth in the cutout, you do not have a proper seal. The tabs on each side of the bracket have tecth that latch into the ridges. Each tooth is staggered at a different depth(from the front) so only one of the tabs on each side is ever locked into the ridges at any time. Either the two middle tabs or the two tabs diagonal from each other will be engaged 5.
