Used ICs -  STR-G5643D – NT6865UG – STV9118 – LM1246 – LM 1248 – M1237BDKE - LM2470TA – STV9302A – 79A774-1 [LOT] – 2SC5929 [HOT Transistor] Maintain interconnecting ground lead connections between chassis and picture tube dag when operating chassis.  Certain HV failures can increase X-ray radiation. Monitor should not be operated with HV levels exceeding the specified rating for the chassis type. The maximum operating HV specified for the chassis used in this monitor is 24.8KV ± 1KV  with a line voltage of 120/240 VAC. Higher voltage may also increase possibility of failure in HV supply. It is important to maintain specified values of all components in the horizontal and high voltage circuits and anywhere else in the monitor that could cause a rise in high voltage or operating supply voltages. No changes should be made to the original design of the monitor. Components shown in the shaded areas on the schematic should be replaced with exact factory replacement parts. The ...

Basic PLC Ladder Programming Examples 17 Basic PLC Ladder Programming Training Examples for Beginners.  Hi friends here we are starting here a series of Free Training on PLC Ladder Programming training & tutorials.These PLC Ladder Programs are important to get basics of Ladder programs.  PLC Ladder Practice Problem:  When the Start push button is pressed both motors must run After 10 Sec motor 1 Stops Motor 2 continues running for another 5 sec and stops At this point a lamp is switched on. After 10 Seconds Lamp goes off and cycle restarts . If stop switch is operated at any time , the system will continue to the end of the cycle and then stop. Topics Covered in this example is Conditional Contacts  Ladder Program. Number of PLC Inputs Required X0 – START pushbutton to Start Motor X1 – STOP pushbutton to Stop Motor Number of PLC Outputs Required Y0 – Motor 1 Y1 – Motor 2 Y2 – LAMP PLC Ladder Programming: Note: Example is only for training purposes. No practical i...
