K1 Power Supply 5KV Sequence Of Events

When the charge button on a 5KV K-1 power supply is depressed, following sequence of events should occur.

30V is always available at logic board 14 from P S TB1-2.

When the charge button is depressed, the 30V is sent to the logic 20.

A pulse from logic C2 momentarily energizes logic relay K2.

K2-7 puts 30V at relay K-1 coil Which keeps relay K2 energized thru relay K1-10.

Relay K1-7 provides 25V to energize the dump solenoid and raise the dump plunger from ground.

Relay K2-7 also puts 30V at logic 16 Which energizes P S relay K-1 (magnacraft relay) which puts 115V at T3 primary for charging voltage.

The capacitor bank is charged by T3 secondary thru J6.

The voltage sense singal goes into logic 22 and turns on Q2 when the pre-set digidial voltage is reached.

When Q2 turns on, logic relay K3 is energized and 30V at relay K3-8 goes to relay K3-10 which turns off relay K2 which de-energizes P S relay K-1.

When P S relay K-1 is de-energized, charging stops.

Relay K1 remains on because of 30V applied from relay K3-7.

Relay K3-7 also turns on the fire light and makes available 30V at logic 29 when the fire button is depressed.

The 30V at logic 29 turns on logic cr-16, causing negative going pulse to occur at logic 33 and 34.

T4 then injects a trigger voltage into the flashlamp.

When the capacitor bank discharges, the voltage sense signal at logic 22 is removed, Q2 turns off and relay K3 de-energizes, causing relay K-1 to de-energize.

When relay K-1 de-energizes, the dump solenoid plunger is fire to fall and the dump light goes on.

The system is now at rest until the next charging cycle.

If the dump button is pressed at any time in the charge cycle, relay K-1 de-energizes, the dump plunger falls and the system goes to reset.
