The Will-Burt PositionIT™ is a pan and tilt positioner system designed for various applications, allowing for precise control of payloads mounted on a mast. This operator's manual covers three main models: PI-35 (P/N: MM233TX2TXRX2), PI-75 (P/N: HM211TXXDXRX2), and PI-150 (P/N: HM211TX2DXRX2). The system is controlled by a default joystick controller (P/N: 5098901) and can also be managed via GPS Control, Infrared Remote Control, or RS-232 GUI Interface (customer supplied only).
Function Description:
The PositionIT system enables precise pan and tilt movements of a mounted payload. The positioner can be set to specific preset positions, and its movements can be controlled manually via a joystick. The system incorporates electronic limit stops to prevent over-travel and damage. It is designed to be robust, with features like die-cast aluminum casing, stainless steel fasteners, and IP68 rating for weather and dust proofing, ensuring reliable operation in various environments. The system can be powered by 12 VDC, 24 VDC, or 120/240 VAC (50 or 60 Hz) depending on the model and power supply used.

Usage Features:
- Controller: The default joystick controller (P/N: 5098901) features pan and tilt functions, is Pelco D compatible, includes a joystick, LCD screen, and a keyboard. It supports programmable presets and electronic limits, and offers speed control. The controller is designed to handle inclement weather and is kept in a protected environment.
- Power/Data Cable: The system uses 16 AWG twisted pair for power and 22 AWG twisted pair for control wires. Cables are available in 35 ft. (10 m), 66 ft. (20 m), and 99 ft. (30 m) lengths.
- Positioner Power Supply: A 120 VAC (50 or 60 Hz) or 240 VAC (50 or 60 Hz) input power supply (P/N: 208016) converts to 24 VDC output. It has short circuit, overcurrent, overvoltage, and over temperature protections, and is IP67 rated.
- Barrel Connector: A 2.1 mm barrel connector (P/N: 5195601) connects the controller to the step down converter or 12 VDC power source.
- Quick Overview: Installation involves mounting the positioner with high-strength bolts, wiring it according to the schematic, mounting the payload, attaching the controller, and operating the positioner using the controller. Preset positions and electronic limit stops can be configured.
- Pre-Operation Check: Before operation, ensure the positioner is kept clean, visually inspect for damage, verify proper training and certification of personnel, ensure all required tools are readily available, and confirm all warnings are understood.
- Mounting the Positioner: The positioner can be identified by its side egress. The manual provides detailed instructions and diagrams for mounting hole patterns for PI-35, PI-75, and PI-150 models.
- Wiring the System: Detailed instructions are provided for connecting the positioner plugs, carefully pulling away the removable plug and gasket, disconnecting wires, and securing the plug plate.
- Connecting Power and Controls: The system can be powered with 12 VDC, 24 VDC, or 120/240 VAC. Wiring diagrams are provided for each power configuration, detailing connections for the 5-pin plug (power/data cable), 22 AWG green/white wires (data A, + and data B, -), and 16 AWG red/black wires (power/data cable).
- Mounting the Payload: Instructions emphasize ensuring the payload is within specified limits and using appropriate hardware to prevent vibration loosening. Mounting hole patterns for PI-35, PI-75, and PI-150 payloads are provided.
- Setting Presets and Electronic Limit Stops: The positioner allows setting electronic limit stops to prevent over-travel. Presets (1-50) can be configured and recalled. Factory default settings for limits can be restored.
- Operation Tools: Safety glasses, safety gloves, safety shoes or combat boots, hard hat or helmet are recommended.
- GUI Installation and Setup: The manual describes installing the GUI on a PC, Laptop, or Tablet, connecting via USB to RS485 half duplex, and setting up the Easysync unit and WB Positioner. It includes steps for updating firmware, setting baud rates, and configuring parameters.
- Presets and Stow & Unstow Setup: Presets can be stored (1-50) and recalled. The positioner can be moved to the mid-point of pan and tilt, which is referred to as the Home position. A customer can program a stowed position by setting preset position [1] and an unstow position by setting preset position [2].
- Keyboard and Joystick: The keyboard includes menu, monitor, camera, number keys, set, preset, previous, and enter functions. The joystick controls pan and tilt movements, with speed proportional to the lean angle. Menu functions are accessed via the joystick.
- Setting and Recalling Presets: Instructions for setting presets using the keyboard and recalling them are provided.
- Adjusting and Restoring Electronic Limit Stops: Electronic limit stops can be adjusted via the keyboard. Default limit stops (left, right, up, down) can be restored using specific preset numbers.
- Stowing and Transporting: The positioner can be stowed to preset position [1] before transportation. Proper securing of the payload is the customer's responsibility.
Maintenance Features:
- Routine Maintenance:
- Visually inspect the positioner to ensure it is kept clean.
- Visually inspect for damage.
- Inspect all fixings and fastenings for tightness (1 month following installation, then every 6 months).
- Inspect cables for damage or improper termination.
- Ensure no water can enter the positioner through connectors.
- Troubleshooting Guide: The manual includes a comprehensive troubleshooting guide (Table 5-1 and Table 5-2) covering common issues such as the positioner not panning or tilting, panning or tilting improperly, inability to access the controller menu, controller being stuck in a menu, and the controller display being off. Possible causes and remedies are provided, including checking schematics, power supply, system settings, wiring, and resetting electronic limit stops or factory defaults.
- Restoring Factory Defaults: Instructions are provided for resetting CamID, MonID, Protocol (Pelco-d, Pelco-p, DH-SD), and Baud Rate to factory defaults. This involves navigating through the controller's menu using the joystick.
- Supported Pelco D Commands: A table (Table 6-2) lists standard, extended, advanced, and custom Pelco D commands with their Op Code, Hex Code, and Decimal Code for advanced control and troubleshooting.
