Toro Sentinel Map To Installation Instructions Catalog

Sentinel Map To Universal Satellite Controller Installation Instructions Important: For your protection and the safety of the product user, please comply with all Caution and Warning statements within this document. All installation practices must comply with all applicable national and/or local electrical and building codes and be performed by qualified personnel only. Introduction The pedestal-mount satellite controller unit is designed for installation on a substantial concrete pad with embedded conduit of various diameters to enable wiring connections for power, field, earth ground, sensor and optional external antenna.

Pedestal anchor bolts and a steel bolt pattern template are supplied with the controller. The wall-mount satellite unit is designed for installation on a structurally-sound building wall. The stainless steel cabinet is moisture resistant and suitable for outdoor installation. The cabinet has upper and lower support attachments and is supplied with a mounting bracket which attaches directly to the wall. Refer to wall mount installation procedures on page 2. Additional materials required to complete the installation must be obtained separately. A material list can be compiled by reading through the instructions completely prior to starting the installation. Pedestal Installation 1. Prepare a hole for the pad and wiring conduit using the minimum recommended dimensions shown in Figure 1. This size pad requires approximately four cubic feet of concrete. * N ote: Refer to local electrical codes for the required wire burial depth. 2. Position straight and sweep elbow conduit sections in foundation hole as shown. Note: Placing the controller toward the back of the pad as shown protects the ground near the front of the controller from wear. 3. Tape the conduit ends to seal out dirt. Backfill soil to form a 6 ” (15 cm) foundation depth. The conduit should not extend more than 2 ” (51 mm) above the finished top surface of the foundation. 4. Form the perimeter of the pad area using 2 x 6 boards or 3/4 ” (19 mm) plywood. 5. Prepare the mounting bolt template with the provided L-shaped bolts and hex nuts as shown in Figure 1. 6. Pour concrete into the formed area and trowel smooth. Finish the concrete pad with a level flat area for the pedestal base approximately 8 ” x 17 ” (20 cm x 43 cm). 7. Aligning the mounting bolt template with the conduit, press the L-shaped bolts into the concrete until the template makes contact. To prevent pooling at the base of the pedestal, add a slight taper away from the template. Allow the concrete to sufficiently harden before continuing. 8. Remove the mounting bolt hex nuts. Remove and discard the mounting bolt template. Place the pedestal on the pad ensuring all bolts are inserted into the pedestal base. Install a flat washer and a hex nut on each bolt and tighten securely.

Position the upper support bracket on the wall with the joggle edge up to accept the mating upper cabinet bracket. The support bracket must be level and at a height approximately 2 ” (51 mm) above eye level to enable the Sentinel control module display to be easily viewed. 2. Mark the two mounting screw hole locations and drill pilot holes for the screws or screw anchors. Note: Use 3/8 ” (10 mm) diameter fasteners to attach the cabinet support brackets. If installing the cabinet on dry wall or masonry, install the appropriate size and type screw anchors. 3. Secure the support bracket to the wall. Hang the cabinet on the wall by engaging the upper cabinet bracket and the support bracket. 4. Draw a pencil line the entire length of the lower support bracket. 5. Remove the cabinet from the wall and remove the lower support bracket from the cabinet. 6. Place the lower support bracket on the wall aligning it with the pencil mark. 7. Mark the two screw hole locations and drill pilot holes for the mounting screws or screw anchors. 8. Secure the bottom support bracket to the wall. *Note: On early model cabinets, conduit access holes are only provided for power and one field wire conduit. Additional conduit access holes for earth ground, additional field wire conduit, optional sensor wires and optional external antenna must be cut or punched by the installer. All conduit access holes and knock-outs are provided on current production cabinets. 9. Remove optional conduit knock-outs as required for installation. See *Note above. 10. Hang the cabinet on the the wall mount support bracket. The bottom edge of the cabinet should now rest squarely on the lower support bracket. 11. Secure the cabinet to the lower support bracket using the carriage bolts and nuts removed in Step 5 above. 12. Install electrical conduit for all wiring connections per local and national code.

The satellite surge protection components cannot properly function unless an efficient pathway to earth ground is provided. The ground path must be as direct as possible, without sharp bends and must not exceed 30 ohms resistance (when measured with an earth ground resistance test device). A resistance reading of 0­10 ohms is considered excellent, 11­20 ohms is acceptable and 21­30 ohms is considered marginal. All electrical components throughout the irrigation system should be grounded in a manner which provides the same ground potential. The following instructions depict one of several acceptable earth grounding methods. Due to variables in soil composition and terrain, the method shown may not be suitable for your installation site. Contact your local Toro distributor for assistance and availability of the required earth ground resistance test instrument. Recommended ground testers are: AEMC Instruments, model 3710 clamp-on tester, or Biddle Megger, model 250260 (or equivalent). Procedure Figure 4 1. Drive a 5/8 ” by 8′ (17 mm x 2.4 m) Chassis copper-clad steel rod into well moistened Ground Lug soil not less than 8′ (2.4 m) or more than 12′ (3.7 m) from the satellite. The top of the 6 AWG (10 mm ) ground rod should be 12 ” (30.5 cm) below Solid Copper Ground Wire grade level. See Figure 4. Valve Box 2. Using a 5/8 ” (17 mm) clamp or “Cad weld ” fastener, attach a 6 AWG (10 mm2) solid copper wire near the top of the ground rod. Avoiding wire bends of less than 8 ” (20.3 cm) 12 ” (30.5 cm) 8 ” (20.3 cm) radius and more than 90°, route the wire Minimum through conduit into the controller cabinet. Radius Secure the wire to the large copper ground lug. See Figure 4. 8′ ­ 12′ 90° (2.4 m ­ 3.7 m) Note: Make sure the soil surrounding the Ground Wire To ground rod(s) remains well moistened at all Additional Ground times. The addition of some form of irrigation Copper-Clad Rod(s) (Optional) may be required if the satellite is installed in Ground Rod a non-irrigated location. 3. Measure the ground resistance per the instructions provided with the ground test instrument. If the resistance exceeds the acceptable limit, additional ground rod(s) can be installed at a distance equal to twice the buried depth of the first rod; i.e., 16′ (4.9 m). Interconnect the ground rods using 6 AWG (10 mm2) solid copper wire and test again. If the measured ground resistance continues to read above the acceptable limit, contact your local Toro distributor for further assistance and recommendations. Note: Installing a round valve box over the ground rod enables the ground rod to be easily located as well as providing access to the ground wire connection(s). 2 Input Power Installation Caution: When installing multiple controllers, polarity of the Line and Neutral connections must be properly maintained throughout the irrigation system. Reversed polarity may cause damaging potentials to exist at one or more controller locations. An equipment ground wire from the power source must be connected to each satellite controller. WARNING AC power wiring must be installed and connected by qualified personnel only. All electrical components and installation procedures must comply with all applicable local and national electrical codes. Some codes may require a means of disconnection from the AC power source, installed in the fixed wiring, having a contact separation of at least 0.120 ” in the line and neutral poles. The wire used for connection to the controller must have insulation rated at 105°C minimum. Ensure the AC power source is OFF prior to servicing or connecting to the controller. 3 Input Power Installation (continued) Note: Refer to Figure 5 for the following procedure. Ensure the controller power source is off.
