Introduction
This chapter contains general installation instructions for the Flo-TechTM Speed Control. Power requirements, ambient temperature limits, and location considerations are included to determine the best location for the control.Speed Control Installation
Unpacking
Be careful when unpacking the electronic control. Check the control for signs of damage such as bent or dented panels, scratches, and loose or broken parts. Notify the shipper and Woodward if damage is found.Mounting
The control box is designed to operate within a temperature range of -40 to +70 °C. (-40 to +158 °F).Mount the control in a location with space for adjustment and wiring access. Do not expose the control to sources of radiant heat such as exhaust manifolds or turbochargers. Choose a protected location so the control won't be damaged when moving the engine or when nearby equipment is moving. Mount the control close enough to the fuel valve and battery to meet the wire-length requirements (see wiring instructions in this chapter).Do not install the control box directly on the engine.The control will generate some heat, and surfaces must be open to normal air movement. No special ventilation is required.Ideally, the control should be mounted flush to the metal side of a control cabinet, protected from the weather and high humidity, and close to the engine being controlled. The location should provide protection from high-voltage or high-current devices, or devices which produce electro-magnetic interference. After initial adjustments are completed, all functions may be selected with remote switches on the control panel. Ready access to the control will not be required for normal engine operation.Magnetic Pickup
Install the magnetic pickup (MPU) to work with the selected gear through a housing or rigid bracket. Make sure the sensed gear is of magnetic material. Set the gap between the gear and the end of the magnetic pickup according to instructions which accompany the pickup.Magnetic pickups of various sizes are available from Woodward.The standard models of magnetic pickups require mating connectors, MS 3102R-18-3P. The connectors can be furnished with the MPU ordered from Woodward.Manual 82510 Magnetic Pickups and Proximity Switches for Electric Governors contains detailed information on the installation of the sensing device.Wiring Instructions
External wiring connections and shielding requirements for a typical control installation are shown in the plant wiring diagram (Figure 1-3). These wiring connections and shielding requirements are explained in the balance of this chapter.Electromagnetic interference (EMI) is the undesirable interaction of electronic circuits with each other and sometimes with themselves.Woodward Governor Company has established procedures to prevent most EMI which will affect prime-mover-control circuits. Following these procedures is a slight extra expense in planning and installing electronic governing systems, but is inexpensive insurance over the life of the plant. Follow all of the shielding instructions to assure maximum efficiency and dependability of the electronic governing system.Application Note 50532 EMI Control for Electronic Governing Systems has additional information on EMI causes and prevention.Shielded Wiring
All shielded cable must be twisted conductor pairs. Do not attempt to tin the braided shield. All signal lines should be shielded to prevent picking up
