4-32 | Model 933S UV Analyzer
Kp (band)**
The proportional term of the PI temperature control algorithm for each
temperature zone.
Ti (sec)**
The integral term of the PI temperature control algorithm for each tem-
perature zone (seconds).
Startup (%)
The duty cycle used on start-up for each temperature zone during
steady-state operation at the setpoint.
Too Cold (°C)
This is an alarm temperature setpoint for each temperature zone. If the
current temperature of the zone falls below its Too Cold setpoint, it will
cause the analyzer to default to an alarm state. See also the “Tempera-
ture Control” descriptions in the following pages.
Too Hot (°C)
This is an alarm temperature setpoint for each temperature zone. If the
current temperature of the zone exceeds its Too Hot setpoint, it will
cause the analyzer to default to an alarm state. See also the “Tempera-
ture Control” descriptions in the following pages.
Temperature
The current temperature for each temperature zone.
Duty Cycle (%)
The current duty cycle for each temperature zone during steady-state
operation at the setpoint.
Alarm Indicator
The alarm indicator box displays active temperature-related alarms. If
any alarms are active, see “Troubleshooting and Diagnostics” in Chap-
ter 6 for details about the alarm and corrective action to take to reset
the alarm.
