NV Series Transmitters Product Overview Installation Considerations 1
Product Overview The following presentation uses the NV 30/NV 40 as a reference; refer to the next slide for an NV Series Transmitter Comparison table for key differences between the NV 30/NV 40 and other NV transmitters. • Broadband, capable of operation from 87. 5 MHz to 108 MHz. • Frequency change is a single local or remote command (no tuning). • Dynamic bias controlled RF amplifiers allow seamless mode changing. • Plug-in upgrade to HD by adding Exgine (plus applicable license fees). • Operation at rated power up to VSWR of 1. 5: 1. 2

NV 30 / NV 40 Footprint Minimum Clearances: • 1. 2 m (4. 0 feet) at the front to allow for the swing of the front doors and at the top to allow for cable and ducting • 0. 9 m (3. 0 feet) at the rear to allow for maintenance. The RF output is configured to accept a non-gas type 4 -1/16 inch EIA flange (male) connection; 3 -1/8 inch EIA is standard. 19
Ac Source Requirements • Option: 3 -phase, 4 wire (L, L, L, G) or 5 wire (L, L, L, N, G) • Option: 1 -phase, 3 wire (L, L, G) • 180 and 264 V ac under load (3 -phase or 1 -phase, 50 / 60 Hz). No transformer tapping. • 312 and 457 V ac under load (3 -phase, 50 / 60 Hz). No transformer tapping. • LVPS and SBC/AUI PS have universal input (85 -264 VAC) 20
Ac Wiring Installation Run the ac power cables in a suitable 3 (NV 30) to 3 -1/2 (NV 40) inch trade size conduit, from the ac disconnect switch to the top of the transmitter. Route the ac power cables from the ac entry box to the ac input terminal block (TB 1). 21
AC Installation • Run the ac power cables in a suitable 3 -1/2 (NV 40) inch conduit, from the ac disconnect switch to the top of the transmitter. Pass all ac power source wires, including the ground wire, through the ferrite toroids. • Install the AC power cables to the ac entry box. • Route the ac power cables from the ac entry box to the ac input terminal block (TB 1). • For three-phase ac power sources connect the three ac line inputs to terminals 1 A (L 1), 2 A (L 2) and 3 A (L 3) of terminal block TB 1. Connect the ac neutral (as required) to terminal 4 A (N). Secure all wires in their respective terminals. • Install the RF Feed cable to the RF output connector on the top of the cabinet. Install a ferrite around the feed cable near the transmitter RF output. • Reinstall the ac distribution assembly cover. 22
Input Power Requirements Ac power switch - Install an external ac power disconnect between the ac power source and the transmitter. Power capability figures used in the above calculations are subject to change without notice; contact your Sales Representative for more up-to-date numbers. 23
Antenna • 50 ± j 0 ohms • VSWR - Rated Power achievable up to 1. 5: 1 - Automatic power reduction above 1. 5: 1 - Shutback above 2: 1 - Shutdown above 3: 1 • RF Feed – The antenna feed cable should be a suitably rated coaxial cable. – Output connector: NV 30/NV 40: Non-gas type 4 -1/16 inch EIA flange (male) connection available; 3 -1/8 inch EIA standard. 24
RF Output Remove the output cover plate from the RF output connector on top of the transmitter. The plate is secured using M 6 hardware. Retain this hardware to secure the RF feed cable. 3 -1/8 inch EIA shown for reference 25
Station Reference Ground The site must contain a station reference ground, as defined in Nautel’s Recommendations for Transmitter Site Preparation booklet Components: - transmitter reference ground stud - shield of transmission line - surge box ground stud - 4” copper strap recommended Important • Do not allow conductor to contact the transmitter chassis at any other point. 26
Control and Monitoring Remote control is available via two different methods: Web Based Control: • • From a web browser you can access 100% of the transmitter’s local functionality. An Ethernet port is provided for remote connection to remotely monitor and/or control an NV series transmitter. Discrete Logic Control: • All important status, telemetry and control of the NV transmitter’s operation is available such as on/off control and status, RF power level, power level adjustment, and system reset. • Includes 24 digital inputs, 24 digital outputs, and 8 analog outputs. Each input is preset by Nautel but can be mapped by the user to any available digital control/status within the transmitter. • All digital inputs and outputs are defined using the AUI. 27 27
Remote Input Configuration A single jumper is provided on the Control/Interface PWB to configure all digital inputs for either single ended or differential control. Single Ended Input Configuration (default) 28
Remote Input Configuration Differential Input Configuration 29
Digital Inputs • The 24 digital inputs are connected to terminal blocks J 7, J 8, J 9 and J 10. • Momentary switches S 1 (01) through S 24 (24), which can be labeled according to their function, provide a means to locally activate the digital inputs. • See Table 7. 1 on page 7 -2 (Pre-installation Manual) to determine the input terminal associated with each digital input and to determine the switch associated with each of the digital inputs. 30
Digital Outputs • The 24 digital outputs are connected to terminal blocks J 3, J 4, J 5 and J 6. • Outputs are defaulted to negative logic (current-sink-to-ground) output when a ‘true’ (alarm condition or active status) exists. See note ** below. • Outputs provide an open collector during logic 'false' conditions (non-alarm or non-active status condition). See note ** below. ** Some status outputs are reverse logic; e. g. Summary Alarm, Low and Very Low Forward Power Alarms, and AC Low Alarm – are all active high to prevent a false indication when the transmitter has a low ac condition (open-collector is ‘true’ condition). • Each monitoring circuit must present impedance between the switching device and a positive dc voltage source that results in a current flow of not more than 25 m. A. 31
Digital Outputs continued • A +15 V supply is available for use by the remote monitoring circuits on J 1 -34 or J 1 -35 (ground on J 1 -36 or J 1 -37). • Outputs can be connected to a STATUS (green) or ALARM (red) LED using Bi-position shorting jumpers E 1 through E 24. • The outputs can be labeled according to their function. • See Table 7. 2 on page 7 -7 for a list of the factory preset outputs, their descriptions and their associated output terminals and status LEDs (see “LED configuration”) on the remote interface PWB. 32
Analog Outputs • The dc voltage of each output is between 0 to 6 V, and varies within the real limits of the parameter being monitored. • Analog outputs 1 through 8 connect to terminals of connector J 11 on the remote interface PWB (A 2). • See Table 7. 3 on page 7 -9 to determine the terminal associated with each analog output. • Ground/shield connections are available on various terminals of connectors J 3 through J 10. 33
Installation Parts Nautel will supply - Standard: An ancillary kit (hardware, zip ties, ferrite toroids) is provided with the transmitter - Optional (purchased by customer): Surge protector units • Nautel does NOT supply* - 50 ohm RF transmission line - inner connectors (bullets) - ground strap - external control / monitor wiring - electrical power cables - test equipment / tools * Unless specifically quoted by customer request 34
Ferrite Toroids are provide in the ancillary kit. • Ferrite Toroid Locations – On the coax feed line/cable near the transmitter end – On audio cables near their termination point (only twisted pair and/or shielded cables should be used) – On the AC to the transmitter near the transmitter end (all AC phases wires and AC ground go through the same ferrite) – On the remote control cables near the transmitter end (only twisted pair and/or shielded cables should be used) – On AC cables to any external equipment 35
