Gamma Vacuum SPCe - Display Messages

7. Display messages
During operation, the SPCe may detect and report a number of possible
operating conditions. For example, the SAFECONN connector may become
disconnected, the vacuum may fail, or the ion-pump may have a problem.
These conditions are reported by the following messages on the display:
Display Message Display Meaning
01: Cool down Cycles > 3 Too many cool down cycles occurred during pump starting.
02: Vacuum Loss The voltage dropped below 1200 V while pump was
running.
03: Short Circuit Short circuit condition has been detected during pump
starting.
04: Excess Pressure Excessive pressure condition detected. Pressure greater
than 1.0e
-04
Torr detected. (Obsolete starting with version
1.15.03)
05: Pump Overload Too much power delivered to the pump for the given pump
size.
06: Supply Power > 50W Supply output power detected greater than 50 W.
07: Start Under Voltage The voltage did not reach 2000 V within the maximum
pump starting time of 5 minutes.
10: Pump is Arcing Arcing detected.
12: Thermal Runaway Signicant drop in voltage detected during pump starting.
19: Unknown Error (Used internally for troubleshooting.)
20: SAFE_CONN Intrlock Safety interlock connection is not detected. Check safe-conn
connection.
21: HVE Interlock HVE interlock function is active on pin 8 on J1 misc i/o
connector. To turn on HV, user must satisfy interlock
(3.3 V d.c. to 12 V d.c. on pin 8 on J1 misc i/o connector).
or 21: HVE Signal O HVE on/o function is active on pin 8 on J1 misc i/o
connector. Logic high (3.3 V d.c. to 12 V d.c. on pin 8 on J1
misc i/o connector) turns on HV. Logic low turns of HV.
22: Set Pump Size Pump size is not set.
23: Calibration Needed Supply calibration has not been performed. Required for
accurate current/pressure readings.
24: Reset Required Supply calibration parameters are outside normal ranges.
System reset will clear all parameters to factory defaults.
25: Temperature Warning Supply internal temperature is past the threshold.
26: Supply Over Heat Supply internal temperature too high. HV operation is
disabled.
27: Current Limited Supply current is limited. The limit is set by programming
the pump size or manually by the user.
30: Internal Bus Error Internal data bus error detected.
