All lightning protection is defensive in nature that is reacting to a lightning strike that has already occurred therefore its effectiveness is limited Nothing can provide total immunity from damage in the case of a direct lightning strike However surge protectors installed immediately after the main power disconnect switch in the power distribution panel will afford some protection from electrical surges induced in the power lines Surge protection devices are designed to operate and recover automatically When operated within specifications a surge protector does not require testing adjustment or replacement All parts are permanently enclosed to provide maximum safety and flexibility of installation To assure the safety of equipment and personnel primary power line transformers must be protected by lightning arrestors at the service entrance to the building This will reduce the possibility that excessive voltage and current due to lightning will seek some low impedance path to ground such as the building metallic structure or an equipment cabinet The most effective type of power line lightning protection is the one in which a spark gap is connected to each primary secondary and the case of the power line transformer Each spark gap is then independently connected to earth ground In cases where driven ground rods are used for building ground the primary and secondary neutrals must be separated by a spark gap If two separate gro

As a result power supply life is expected to exceed 20 years even when sustained daytime ambient air temperature is 104 degrees Fahrenheit Access is easy and there is no danger of tools falling to the bottom of the oil tank because tools aren t needed to remove the submersed components module Rectifier stacks transient sup pression networks and bleeder resistors are mounted on the module They can be serviced on the workbench once the components module is removed from the oil Attached to the oil tank the junction box is where electrical connections to the power supply are made Filter capacitors and primary transient components are mounted here The junction box cover is held in place with several captive type bolt clamps A safety and convenience feature of the cover design allows it to remain in place even if all the fasteners are removed Foot injuries from a falling junction box cover are less likely Handles on the cover aid in its removal and replacement Changing output voltage is straightforward A tap switch handle mounted on the side ofthe oil tank selects up to 5 different output 1 22 1999 Section IV Theory of Operation voltages Access to the tap switch handle is prevented by a lockable hinged cover The cover along with the junction box cover and the shorting stick mounting fixture are equipped with interlock switches that prevent power supply operation if condi tions are unsafe All electrical components in

235. ING THE TRANSMITTER AT VERY LOW AMBIENT TEMPERATURES At very low coolant temperatures around 20 C 4 F the ability of glycol water mixtures to remove heat is severely reduced Before powering the IOT at full beam power the coolant should be at a temperature of at least 5 C 41 F Therefore at lower temperatures it should be prewarmed by running the IOT on idle current only or by any other appropriate means For example allowing the coolant to circulate all night during periods of very low ambient temperature may maintain the coolant temperature around 5 C due to the dissipation of the energy consumed by the circulating pump provided that the cooling fan on the heat exchanger is turned off Whilst EEV has taken care to ensure the accuracy of the information contained herein it accepts no responsibility for the consequences of any use thereof and also reserves the right to change the specification of goods without notice EEV accepts no liability beyond that set out in its standard conditions of sale in respect of infringement of third party patents arising from the use of tubes or other devices in accordance with information contained herein IOTD270 page 9 Printed in England 888 2414 001 WARNING Disconnect primary power prior to servicing 888 2414 001 WARNING Disconnect primary power prior to servicing IOT BROADCAST BEAM SUPPLY 736 0269 000 HARRIS P N DESCRIPTION QTY UM REF SYSMBOL EXPLANATION

U1 as a power refer ence The transmitter sample is compared to the power reference and the RF attenuator is driven to maintain a constant output power from the transmitter To prevent transmitter over drive conditions the total output power from the PWB is limited to a safe level This level is set by control R11 and is called the AGC limit This limit level is set so that the maximum drive to the IPA and IOT prevents transmitter powers in excess of 110 yet allows the AGC to operate over the temperature range A temperature compensated RF detector CR11 9 and U8 is used to convert the RF sample of the transmitter to a DC voltage In analog transmitters this DC voltage follows the video envelope and is sampled at back porch in a sample and hold circuit Q2 and C30 The back porch sample is applied to J4 from the exciter and is timed to match the detected envelope by a dual monostable U6 In DTV transmitters no sample is provided by the exciter In this case the timing circuit detects the lack of sync pulses by CR12 With no sync pulse present Q3 turns on the sample and hold circuit The DTV signal is random in nature and the RF detector outputs a DC voltage proportional to the RMS level of the DTV signal Power control from the controller ranges from 2 5 to 5 V It is level shifted to 0 to 5V in U17 A VSWR input from the controller is proportional to the reflected power of the transmitter The transmitter is capable of operating
