4.6 Alarm Codes, Descriptions, and Suggested Actions
Description
EPC (Electronic Pressure Controller)
PIC: The measured pressure, on chan‐
nel #n, has exceeded the absolute maxi‐
mum allowed pressure and the corre‐
sponding channel was shutdown. The
pressure controller is no longer working.
EPC (Electronic Pressure Controller)
PIC: The Analog to Digital Converter chip
does not work properly. The flag will be
set if the A/D internal calibration cycle is
not completed within a pre-determined
period of time or the A/D does not report
any valid data within a pre-defined time‐
out period.
Note: A firmware problem affecting the
version 0.250 of the EPC PIC may cause
an A/D failure flag to show-up occasion‐
ally following a PIC reset. This is not a
sign of a defective A/D converter.
EPC (Electronic Pressure Controller)
PIC: Set when the contact on the optional
supply pressure sensor on [J5 or J6] is
closed indicating that the supply pres‐
sure is getting low and that the bottle
must be changed soon.
EPC (Electronic Pressure Controller)
PIC: The measured pressure deviation
has exceeded the corresponding
MAX_DEVIATION value. The PID con‐
trol was not successful in controlling the
pressure with the desired precision on
channel #n.
EPC (Electronic Pressure Controller)
PIC: The SETPOINT_[n] AO value was
modified internally as a result of the SET‐
POINT_MAX_[n] AO value set to a value
lower than the SETPOINT_[n] value.
General Maintenance and Troubleshooting
Action
Confirm that the flow is greater than the
minimum specification. Replace the
EPC.
Cycle power. If the error repeats con‐
sistently, replace the module.
Check air supply. Replace supply bottle.
MAX_DEVIATION_x that is too small.
An improper setting of TIME_LIM‐
IT_DEVIATION_UP_x or TIME_LIM‐
IT_DEVIATION_DN_x.
Insufficient supply pressure.
Flow too small or too large.
Defective EPC.
Set the SETPOINT_MAX_[n] value first
and then set the setpoint.
