accumulates, as such the actual time that an ATC cycle runs depends on the output current of the
supply and the target cycle time (cycle preset value).
Once a timed operate cycle is started it will run for the specified period of real 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 operate control digital input, or by a serial host port command (see 8: Remote
Operate/Standby Control for details on remote 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).
To configure the supply for timed cycle control set the cycle control setting to “RTC” or “ATC” and
set the desired cycle time in the cycle setup menu. Use the following procedure to configure the
supply for RTC or ATC cycle control. See A.6.1: 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.6: 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 indicated 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 “rtc” for real time control or “Atc” for amp time control. 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” “Unit”. Then press the voltage encoder to view and change the cycle time
units.
6) If the cycle control type is set to “rtc” the cycle time units are indicated by “rtc” on the
top display and the selected time units on the bottom display. If the control type is
set to “Atc” the cycle time units are indicated by “Atc AmP” on the top display and
the selected time units on the bottom display. The SET lamp is blinking on and off to
indicate that a setting is displayed. Rotate the current encoder to select the desired
units. Select “min” for RTC minutes or ATC amp minutes and “hr” for RTC hours or
ATC amp hours. Once the desired units are selected press the voltage encoder
switch to accept the setting and return to the “Cycle Setup Menu”.
