circuit will remain open until the manual reset button (located between the two wire terminals) on the thermostat is
pressed or the temperature drops approximately 30% below the set-point.
A DIN rail near the bottom holds fuse terminal blocks, the main breaker, and terminal blocks for all external
connections. The temperature controller controls the heater in the sample cell enclosure via the solid-state relay.
NOTICE
 See Fig 7. Components in SS2100i-2 electronics enclosure for locating fuses. If you need to replace a fuse, use
only the same type and rating of fuse as the original as listed in the tables below.
In the sample cell enclosure, the sample cell is the actual TDLAS spectrometer through which the gas sample flows.
The sample cell is equipped with a pressure sensor and thermistor to monitor the thermodynamic conditions of the
sample. The heater maintains the inside of the analyzer enclosure at a constant temperature with air circulated by
the fan.
