for details on the “Ramp Setup Menu”.
1)
Enter the “Unit Setup Menu” by pressing and holding both encoder switches until the
display shows “Unit” “SEt” (see
for details).
2) Rotate the current encoder unt
il the display shows “SEt” “rmP”. Then press the
voltage encoder switch to enter the “Ramp Setup Menu”.
3)
From the “Ramp Setup Menu” rotate the current encoder to select either the current
or voltage ramp setting. The top display will show “rmP”, the bottom display will
show “Curr” for current tolerance or “UOLt” for voltage tolerance. Once the desired
signal is selected press the voltage encoder switch to view and change the
associated ramp setting.
4) The ramp
setting is indicated by “Curr” “rmP” “SEC” on the top display for current
ramp time or “UOLT” “rmP” “SEC” on the top display for voltage ramp time. The
selected ramp time in seconds (xxx.x) is displayed on the bottom display. The SET
lamp is blinking on and off to indicate that a setting is displayed. Rotate the current
encoder to change the selected ramp time digit (blinking on and off). Each press of
the current encoder switch selects the next digit. Enter a ramp time of zero to
disable ramping for the associated signal. The maximum allowable ramp time is 300
seconds. Once the desired ramp time is set press the voltage encoder switch to
accept
the value and return to the “Ramp Setup Menu”.
5) To change another ramp time repeat the above procedure starting at step 3 above.
To exit the “Ramp Setup Menu” rotate the current encoder until “rmP” “End” is
displayed. Then press the voltage encoder switc
h to exit the “Ramp Setup Menu”
and return to the “Unit Setup Menu”.
6) If any ramp settings were changed you will be prompted to store the changes.
Select “yES” to accept the changes or “no” to cancel the changes.
7)
From the “Unit Setup Menu” rotate the current encoder until the display shows “SEt”
“End”. Press the voltage encoder switch to exit the “Unit Setup Menu”.
6.4.7. Tolerance Settings
The power supply can be configured to report an error code when the current and/or voltage
reading is out of tolerance. The out of tolerance error code is displayed on the front panel (see
for details on how error messages are displayed) and is reported in the serial
host port alarm status message (see
status message). Out of tolerance errors do not affect power supply output or operate/standby
state. Once an out of tolerance error is set it will remain set until a new cycle is started or the
error is manually cleared (see
for details on manually clearing error
codes).
Tolerances are set as a percentage of the associated setting. Tolerance alarms are set when the
signal reading varies from the expected average reading by more than the selected tolerance
percent. A tolerance setting of 0% disables out of tolerance error reporting for the associated
signal. A current tolerance setting of 10% will cause an out of tolerance error to be set if the
current reading differs from the expected current reading by more than 10%.
The expected average reading is a computed value based on the output settings. The expected
reading is the computed average reading for the associated signal when the signal is regulating
power supply output. For a pulse output having a peak current setting of 500 amps and an on
