Description
Temperature of the TEC#1 (181) is
outside of a band set by parameter 183
around the setpoint (188)
Temperature of the TEC#2 (374) is
outside of a band set by parameter 376
around the setpoint (381)
Cell temperature (192) is outside of a
band set by parameter 194 around the
setpoint (193)
Pressure transducer reading (244) is
outside of a band set by min/max
pressure (236, 237)
For ATEX ONLY: SEAL pressure (366)
is outside of a band set by min/max
pressure (369, 370)
File system error, reported in system
alarm (125)
Internal harware error
TEC temperature (181) drifts out of
factory setting window (197, 198)
defined by the factory default (276)
