Error Number Explanation Corrective Action
Error #2 AC line voltage too high Ensure that the power source is in compliance with
the electrical specification of the system.
Error #3 Solid State Relay’s path shorted Replace the power and control P.C. board.
Error #4 Heater circuit failure—short Replace the power and control P.C. board.
Error #5 Solid State Relay #1 failure—
open
Replace the power and control P.C. board.
Error #6 Solid State Relay #2 failure—
open
Replace the power and control P.C. board.
Error #7 Safety relay failure—short Replace the power and control P.C. board.
Error #8 AC heater current high Inspect the quartz tube heating element. If neces-
sary, replace it. Otherwise, replace the power and
control P.C. board.
Error #9 Hardware detects a high tem-
perature >39.5°C (103.1°F)
If the heater is on, replace the power and control
P.C. board. Otherwise, check for an ancillary heat
source.
NOTE:
This error is not included in the error log.
Error #10 Power Fail circuit failure Replace the power and control P.C. board.
Error #11 CPU voltage out of specifica-
tion
Check the voltage from the DC power supply.
Error #12 Keypad failure Replace the display P.C. board.
Error #13 ROM test failure Replace the power and control P.C. board.
Error #14 RAM test failure Replace the display P.C. board.
Error #15 EEPROM test failure Replace the power and control P.C. board.
Error #16 Analog/Digital (A/D) offset out
of specification
Replace the display P.C. board.
Error #17 Analog/Digital (A/D) gain out
of specification
Replace the display P.C. board.
Error #20 External watchdog timer fail Replace the power and control P.C. board.
Error #21 Ambient temperature probe
error >0.4°C
Check for damaged ambient temperature probes.
The ambient temperature probe is internal, and must
be attached in order for the unit to function properly.
