IMl015 Section 1 GENERAL INFORMATION 1.1 GENERAL DESCRIPTION The TD monitor is a solid state unit for use in industrial, commercial and data display fields, where reliability and high quality video reproduction are desired. Applications such as remote monitor for computer terminals and airline flight arrival/departure displays are ideally suited to this unit. 1he TD monitor has a single plug-in circuit board with silicon transistors.
IMI015 POWER SUPPLY Input voltage: 100 to 240 AC, 50/60 Hz Input Power: 46W Nominal Output voltage +57 VDC short circuit protected +18 KV nominal ENVIRONMENTAL Temperature: Operating range: 5 0 C to 55 0 C ambient Storage range: -40oC to 65 0 C ambient Humidity: 5 to 80% (non-condensing) Altitude: Operating: up to 10,000 ft. S tor age : up to 14, 00 C ft. 1.
IM1015 Certification of compiiance with radiation regulations is shown by a label attached to each monitor. The user is responsible for labeling his product in a similar fashion or in making the DHEW label easisly visible from the outside of the enclosure. The regulations state that "This (certification) information shall be provided in the form of a tag or label permanently affixed or inscribed on such product so as to be legible and readily accessible to view when the product is fully assembled for use .
IMl015 Section 2 INSTALLATION INSTRUCTIONS 2.1 GENERAL This section describes the installation procedures of the TD series monitor. It also contains information on the space, power and cable termination requirements of the monitor. 2.2 SPACE The TD-23 monitor occupies an area of 18 inches high, 23-1/16 inches wide and 18-1/2 inches deep. 2.3 POWER The external power requirements of the unit is 105-130 VAC, 50-60Hz, 46 watts nominal.
IM1015 If a ground loop hum is apparent in the picture, placing the differential input switch S2 in the ON position will remove any hum induced in the cable between the monitor and the equipment which is causing it. If a ground loop hum is not apparent in the picture, leave the differential input switch in the OFF position. 2.6 INITIAL TURN-ON PROCEDURE The TD monitor was tested and aligned before shipment, and should not require further adjustment after installation.

IMlOls SECTION 3 CIRCUIT THEORY 3.1 GENERAL INFORMATION This section describes the circuit theory of the TD series monitor. This section is to be used with the waveforms and schematics found in section 5 and 6 of this manual. 3.2 VIDEO AMPLIFIER The video amplifier consist of transistors QlOl through Ql03, integrated circuit UlOl and transistor Q10S through Qlll. A composite video signal is applied to the PWA through Jl02-3 and is ac coupled to the differential amplifier.
IMl015 driver at the high frequencies to compensate for the capacitance in QllO and at the cathode of the CRT. The signal at the collector of QllO is direct coupled to the base of the emitter follower Qlll, which provides a low source impedance for driving the cathode of the CRT. Vertical retrace blanking is applied to the base of Ql09, which conducts harder during this time to increase the voltage at Qlll emitter and drives the cathode of the CRT to cutoff.
IMIOIS The vertical oscillator Ql16 is a thyristor functioning as a programmaole unijunction and operates as a relaxation oscillator. The free running frequency is set by the DC voltage at it's gate and anode. This voltage is determined by the resistive voltage divider network of RIS3, RlS4 and RISS. This voltage can be varied by the vertical hold control RIS4. The oscillator is synchronized by a negative vertical sync pulse applied to the gate of Ql16 from QllS through C123.
IMl015 of Q120 and Q12l varying inversely with temperature. As the temperature increases, the thermistor resistance decreases; thereby lowering the effective source voltage applied to the main timing network consisting of R187, R185 and C140. This action slows down the charging current into C140 and holds the off time of Q12l constant. The other timing network for Q120 and Q12l consists of R18l and C138.
IM1015 C158 serves to block DC currents through the yoke and to provide usn shaping of the current waveform. "S" shaping compensates for stretcnlng at the left and right sides of the picture tube because the curvature of the CRT face and the deflected beam do not describe the same arc. L103 is an adjustable width control placed in series with the horizontal deflection coils.
IMIOl5 To set the supply for a particular line voltage, the numbers on the two switches are added together. This allows the supply to be set for four different input line voltages. The position of the switches and the resultant input voltages is shown in the schematic.
IM1015 SECTION IV ADJUSTMENT AND MAINTENANCE 4.1 GENERAL This section is for the adjustment procedures and maintenance procedures for the TD series monitor.
