Manual Overview

The Sencore HA2500 Substitute B+ Supply manual provides detailed guidance on using the device to troubleshoot and isolate issues in horizontal output stages and high voltage/deflection regulators. The Substitute B+ Supply allows testing at full operating voltages independently of the chassis B+ power supply, helping to identify component failures without risking damage to the power supply. Technicians should start with the VOLTS control set to “OFF” when connecting or disconnecting the B+ supply leads. The device outputs 30 to 180 volts and includes a POWER LIMIT control to adjust the maximum power output, which is crucial for preventing damage during testing. The manual emphasizes the importance of opening the chassis B+ voltage path before substitution to avoid damage. The digital display provides real-time voltage and current readings, ensuring accurate monitoring. Technicians are advised to start testing at reduced voltage levels and gradually increase to normal operating levels, using the HA2500’s dynamic tests to assess the horizontal output stage’s performance. Safety precautions are highlighted due to the potential shock hazard from voltages up to 180 volts.

Quick Issues Covered

• Diagnose horizontal output stage failures with substitute B+ voltage.
• Isolate high voltage component issues without chassis power risk.
• Trace circuits using schematics to identify B+ voltage path.

Operation

The HA2500’s Substitute B+ Supply is a tool used for testing and troubleshooting horizontal output stages and high voltage/deflection regulators in CRT video displays. It allows for the substitution of the chassis B+ voltage, enabling the identification of high voltage component problems without risking damage to the chassis power supply. The Substitute B+ Supply is a variable DC power supply adjustable from 30 to 180 volts and is designed to substitute for the full range of chassis B+ power supply voltages.

To use the Substitute B+ Supply, the following steps should be followed:

1. Ensure the VOLTS control is set to “OFF” when not using the Substitute B+ Supply, and when connecting and disconnecting the B+ SUPPLY LEADS to the chassis or B+ SUPPLY OUTPUT Jacks.
2. Open the chassis B+ power supply path to the horizontal output stage to prevent the chassis B+ voltage from reaching it.
3. Connect the B+ SUPPLY LEAD clips from the B+ SUPPLY OUTPUT Jack to the chassis.
4. Start at a reduced voltage or power level and slowly increase the voltage or power until full operation of the horizontal output stage is reached or defects are observed.
5. Use the VOLTS and POWER LIMIT controls to adjust the output to desired levels, starting with the VOLTS control to “OFF” and setting the POWER LIMIT control to a power setting near the anticipated power demand.
6. Use the HA2500’s Dynamic Tests to determine abnormal or normal operation of the horizontal output stage when substituting for the chassis B+ voltage.

The Substitute B+ Supply outputs over 80 watts for voltages greater than 40 volts, with current limited to 2 amps for voltages between 30 and 40 volts. The power output can be adjusted using the POWER LIMIT control, and a LIMITING light indicates when the output voltage times current exceeds the POWER LIMIT setting. The fluorescent digital display shows the voltage and current outputs simultaneously.

Safety & Warnings

The HA2500’s Substitute B+ Supply should only be used by technically qualified persons who understand the potential shock hazard of voltages up to 180 volts. Voltages greater than 30 volts DC can deliver a lethal electrical shock. It is important not to come in contact with the B+ SUPPLY OUTPUT Jack, B+ SUPPLY TEST LEAD clips, or B+ supply circuit points when using the Substitute B+ Supply.

Operation

The LC102 AUTO-Z power supply can be used for various applications beyond capacitor leakage testing. It is capable of high-potential testing and testing resistances up to 1 gigohm. The power supply is portable, battery-operated, and provides a regulated, well-filtered, current-limited DC output adjustable in 0.1 volt steps from 1.0 to 999.9 volts, with current outputs from 2 mA to 200 mA depending on the voltage selected.

The LC102 is equipped with a STOP TESTING alarm that activates if the fuse opens, protection circuits trigger, or test leads are connected to a charged circuit. If the alarm activates, testing should be stopped immediately, and the capacitor being tested should be discharged using a 10k ohm 1 watt resistor. The test lead fuse should be replaced if blown, or voltage should be removed from the test lead connection point before resuming testing.

The power supply can also be used for testing zener diodes by applying a voltage higher than the zener’s rated voltage through a current-limiting resistor, and monitoring the voltage drop across the diode with an external voltmeter. It is also suitable for powering low-powered devices like small radios and remote controls, and for line tracing in cables by identifying one pair of conductors out of a large cable using its battery operation.

The LC102’s current-limiting feature protects it from damage due to excessive power draw, and its digital current readout aids in troubleshooting.

Troubleshooting & Error Codes

Refer to the PDF for details.

Safety & Warnings

The manual includes the following safety warnings and precautions:

1. If the STOP TESTING alarm is activated, immediately stop all testing with the LC102.
2. The alarm is triggered by either the fuse opening, the protection circuits opening, or connecting the test leads to a charged circuit.
3. The alarm provides alerts through an audible buzzer and a flashing LED.
4. If the STOP TESTING alarm activates, follow these steps:
– Stop all testing with the LC102.
– Carefully discharge the capacitor being tested by connecting a 10k ohm 1 watt resistor across the terminals.
– Replace the test lead fuse if blown, or remove the voltage from the point the test leads are connected to.
– Resume testing.
5. A current-limiting resistor is necessary for most tests to protect the component from damage due to excessive power. The resistor value depends on the current rating of the device being tested. Use 1 watt (or larger) resistors for ample power dissipation when testing shorted parts.
