Page 11: Introduction
Air pressure required to extend the mast is provided by a compressor unit mounted within the Night Scan Chief. The unit is designed for installation on any vehicle for the purpose of providing on the scene temporary lighting. Refer to Figure 1-1 for identification of the major components of the Night Scan Chief unit. -

2.4 ATTACHING TO VEHICLE If the Night Scan Chief is to be mounted in a well, be certain that adequate drainage is provided. A minimum of (4) drain holes (one per corner) at least one inch in diameter is recommended. While the unit has been designed to withstand adverse environmental conditions, it cannot be submerged. -

2.10 MULTIPLEX SYSTEMS OPERATING AT 24 VOLTS When operating at 24 volts, the Night Scan Chief “chops” the voltage sent to the 12 vdc motors is the system. As a result of this starting and stopping, voltage might be fed back through the power wires and into the power supply. - Page 21 Night Scan Chief present. Contact with combustible materials can cause ignition resulting in fire or explosion. Before operating the Chief, be sure that there are no overhead obstructions and that there are no power lines within 20 feet of the mast. Visually inspect the unit for any damage. If damage is apparent, do not use the mast.

Page 23: Operating Instructions
Night Scan Chief CHAPTER 3 OPERATING INSTRUCTIONS All operators must read the Operation section of this manual and be properly trained. Keep personnel clear of mast while during operation. For outdoor use only. Do not use in areas that have been classified as hazardous as defined in Article 500 of the National Electric Code. -
Page 24: Theory Of Operation - Mechanical
Night Scan Chief – Mast The Night Scan Chief operates using a DC powered actuator to drive the mast from nest to 90 degrees. When at 90 degrees, a magnetic sensor detects the actuator position and prevents further driving of the actuator. -
Page 25: Theory Of Operation - Electrical
Another key component of the control is an initialization circuit. In an NFPA compliant installation, a completely stowed Night Scan Chief draws zero current and cannot be extended or operated until the initiate circuit is engaged. Included in this initialization circuit is an input for a safety interlock. This can be used for an emergency stop, or other interlock function such as a “Park/Neutral”... -
Page 26: Push/Pull Switch - Non-Nfpa Installations
Night Scan Chief control by pulling the switch operator. This is a momentary function, and the switch will return itself to a neutral position on its own. Secondly, it functions as an emergency stop when the switch operator is pushed all the way in. -
Page 27: Raising The Mast
Press the “Mast Down” button until the mast has completely stowed. Note : In the Night Scan Chief, during the process of raising the mast, the mast will first be inclined to a position perpendicular to its mounting surface by an actuator. Once the control senses it is in this position, air pressure will be applied to the tube sections to raise the mast further into the air. -
Page 28: Emergency Stow (Loss Of Power)
Remote Control. Note : To ensure proper seating of the RCP in Night Scan Chief saddle, the control watches for an increase of current from the actuator. Once this has been satisfied, the control will shut itself off on NFPA compliant installations. -

Night Scan Chief 4.5 TROUBLESHOOTING ELECTRICAL Operating Environment One of the most common causes of improper operation is trying to operate outside of the stated system requirements. (See section Table 1-1for DC power requirements). A good method of checking the voltage at the Chief is to connect a voltmeter to the wires in the junction box powering the Remote Control(s) (pins B and C of J1 (see schematics in section 4.4). - Page 41 Night Scan Chief mast path, and confirm that the proximity switch is being properly activated.
