Table 15: Temperature Control Parameters
Parameter Normal
Value
Explanation
Cell
Setpoint
150°C
Temperature control setpoint for the measurement cell. The
setpoint for the cell MUST be set well above the condensation
point of
sulfur vapour (≈120°C) to avoid plugging due to
accumulation of liquid sulfur inside the analyzer sample
handling system.
Cell Prop
Band
1.0%
Proportional term of the measurement cell electric heater PID
temperature control algorithm.
Cabinet
Setpoint
35°C
Temperature control setpoint for the interior of the analyzer
control cabinet. If the control setpoint is exceeded, the cabinet
cooling air solenoid energizes, providing air flow to the control
cabinet vortex cooler.
Cabinet
Deadband
≥3°C
Control cabinet temperature set point deadband. Indicates the
number of degrees BELOW the control cabinet temperature
setpoint the temperature must drop before switching off the
cabinet cooler cooling air flow. A larger number will reduce the
number of actuation cycles for the cabinet cooler solenoid,
potentially extending its useful life.
Probe
Setpoint
≈110°C
Temperature control setpoint for the sample gas exiting the
probe. If the temperature of the gas exiting the probe into the
analyzer sample system exceeds this temperature, the probe
cooler solenoid activates and the probe cooler switches on.
NOTE: This parameter is only active when a probe RTD is
installed and the Control with RTD function is selected in
the Web GUI (refer to section 5.4).
Probe
Deadband
≥3°C
Probe temperature setpoint deadband. Indicates the number
of degrees BELOW the probe setpoint the probe gas
temperature must drop before switching off the probe cooler
air flow. A larger number will reduce the number of actuation
cycles for the probe cooler solenoid, potentially extening its
useful life.
NOTE: This parameter is only active when a probe RTD is
installed and the Control with RTD function is selected in
the Web GUI (refer to section 5.4).
