Establishing A Minimum Process Voltage; Setting An Out-Of-Setpoint Timer - Advanced Energy Pinnacle 20 kW Manual

ESTABLISHING A MINIMUM PROCESS VOLTAGE

PROCESS → MONITOR → PRC_VOL
This menu lets you establish a minimum process voltage. To use this feature, you must first
enable it and then establish a desired threshold limit. With the process voltage limit feature
enabled, the Pinnacle unit waits for the output voltage to first exceed the limit. Once the limit
is exceeded, output will remain on until you turn the output off or until the voltage falls below
the established limit. If the voltage falls below the limit, output will turn off and error message
E010 will appear on the display.
To enable and set the process voltage level, follow these steps:
1. Press PROCESS → MONITOR → PRC_VOL → ENABLE.
2. Rotate the MODIFY knob to select Yes or No.
3. Press ENTER to accept and exit.
4. Press the LEVEL soft key.
5. Rotate the MODIFY knob to select a process voltage level.
6. Press ENTER to accept and exit.

SETTING AN OUT-OF-SETPOINT TIMER

PROCESS → MONITOR → SETPT
Use this option to enable and set an out-of-setpoint timer. This function lets you indicate how
long you want the power supply to tolerate an out-of-setpoint condition before it shuts off
output. An out-of-setpoint condition occurs whenever output moves out of a range determined
by your selected setpoint. The out-of-setpoint function operates in all three regulation modes.
Note: In units without master/slave cards, out-of-setpoint detection is disabled during arcs
(including short circuits at the supply's output). However, when a master/slave card is
installed, arcs (and short circuits) that are long enough to affect filtered readings
(100 ms or longer) will cause an out-of-setpoint indication.
For a stand-alone unit, the out-of-setpoint limit is 0.4% of full scale or 2% of setpoint,
whichever is greater.
In a master/slave system, the out-of-setpoint limit is 3.125% of full scale, and it is applied to
the entire output of the master/slave system.
Note: The master of a master/slave system is also constrained by the stand-alone out-of-
setpoint limit. This limit (0.4% of full scale or 2.0% of setpoint) only applies to the
output of the master in the system.
When an out-of-setpoint condition occurs, the unit shuts off output and displays error code
E001: OUT OF SETPOINT TIMER EXPIRED. (See the "Error Codes" section of the
"Troubleshooting" chapter for more information about error codes).
