3.5.11 TO PROGRAM THE EXTERNAL CLOCK (CLK=2) (LK Option)
The clock selection is an option for the AC Power System. The CLK screen displays whether the AC Power System is
operating in the external (EXT) or internal (INT) CLK mode of operation. While viewing this screen to select the EXT
CLK mode, depress the EXT key followed by the PRG and ENT key:
Example: EXT PRG ENT
NOTE
Before selecting the External clock mode, ensure that the AC Power System containing
the oscillator has the proper clock and lock signals applied to the BNC connectors on
the rear panel. Failure to have the proper clock and lock signals when the EXT CLK
mode of operation is selected may result in an AMP FAULT error message. No output
from the AC Power System will be available.
To return to the internal (INT) CLK mode of operation, depress the INT or any even numeric key followed by the PRG
and ENT key while viewing the CLK screen.
Example: INT PRG ENT
3.5.12 TO PROGRAM REGISTERS AND RAMPS
The AC Power System has 16 registers that can be used to store setups. All of the data stored in the registers will be
retained during power-down. Register operation may be chained to another register by adding the REC and register
number to any setup sequence. The REC and REG keys are used for register operations. Any of the previous
examples may be stored in a register by adding the extra step of entering the register number followed by depressing
the PRG key. This extra step must be entered before the last ENT keystroke.
The following program will program 135 volts and 60 hertz on all outputs for 10 seconds before reducing the output to
115 volts and store the test in register 0.
1. Select the FRQ screen and program 60 hertz:
6 ENT 60 PRG
2. Select the AMP screen and program 135 volts:
5 ENT 135 PRG
3. Select the RMP screen and program DLY = 10 and VAL = 115
9 ENT A 10 PRG C 115 PRG
4. Store the program in register 0:
0 REG
To recall and perform the register operation, simply enter the register number followed by depressing the REC and ENT
keys.
3.5.13 REGISTER LINKING
Any number of registers may be linked together by using the REC key prior to loading the register operation.
The following program will ramp the voltage from 115 volts and 60 hertz to 135 volts with .1 volts per 10 millisecond
steps, remain at 135 volts for 10 seconds, return to 115 volts at the same rate but at 62 Hz. Store the program in
Registers 1 and 2.
