To configure the supply for manual cycle control set the cycle control setting to “manual” in the
cycle setup menu. Use the following procedure to configure the supply for manual cycle control.
See
A.5.1.Cycle Setup Menu
for details on the cycle setup menu.
1)
Enter the “Unit Setup Menu” by pressing and holding both encoder switches until the
display shows “Unit” “SEt” (see
A.5.Unit Setup Menu
for details).
2)
Rotate the current encoder until the display shows “SEt” “CyCL”. Then press the
voltage encoder switch to enter the
“Cycle Setup Menu”.
3) From the
“Cycle Setup Menu” rotate the current encoder until the display shows
“CyCL” “CtrL”. Then press the voltage encoder switch to view and change the cycle
control setting.
4) The cycle control setting is in
dicated by “CtrL” on the top display and the selected
control type 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 cycle control
type to manual “mAn”. Once the desired control type is selected press the voltage
encoder switch to accept the value and return to the “Cycle Setup Menu”.
5)
From the “Cycle Setup Menu” rotate the current encoder until the display shows
“CyCL” “End”. Then press the voltage encoder switch to exit the “Cycle Setup
Menu” and return to the “Unit Setup Menu”.
6) If any cycle 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”.
6.4.2. Timed Cycle Control (RTC or ATC)
There are two timed cycle control modes. In Real Time Control (RTC) mode an operate cycle
runs for a specified period of time, regardless of the current and voltage settings or the supply
output. In Amp Time Control (ATC) mode an operate cycle runs until the specified amp time
accumulates, as such the actual time that an ATC cycle runs depends on the output current of the
supply and the target cycle time.
Once a timed operate cycle is started it will run for the specified period of time (RTC) or amp time
(ATC) unless it is commanded to stop or to pause the cycle. When a timed cycle completes the
operate state changes to standby (OPER/STBY lamp is off and output is disabled) and the display
flashes “EOC” “----“ (EOC on the display indicates End Of Cycle). In addition the EOC status bit is
set in the host readings command (see
Appendix B:Host Port Protocol
for more information
regarding the host protocol).
A timed cycle can be initiated, stopped, or paused from the front panel using the operate/standby
switch, or by the inhibit input (configurable) or by a serial host port command (see
8.0.Remote
Operate/Standby Control
for details on other methods of operate/standby control). If power is lost
while a timed cycle is running the supply can be configured to automatically resume the cycle
when power comes back on or it can be configured to power on in a paused state allowing the
operator to decide if the cycle should be terminated or resumed (see
6.3.4:Power On
Configuration
for details on how to retain the operate state through a power off/on sequence).
