2.1.2.10 TEMPERATURE INPUTS
The PF2200-SB has three distinct temperature inputs: Bath, Outlet and Stack; each of which are
configurable to be either a Type-K thermocouple or PT-100 RTD input.
Each of the three distinct temperature inputs mentioned above have the following set points that can
be configured via the user interface (note: depending on the mode, the temperature input may or may
not utilize all the set points below; see Temperature Mode for more details):
High Temperature ESD Setpoint: Temperature at which the system shuts down. If the
•
temperature input exceeds this trip point, the system will generate an alarm and if running
proceed to lockout
Pilot Off Setpoint: Temperature at which the system de-energizes all valves, including the pilot,
•
and enters a waiting state. When the temperature falls back down below this value minus the
deadband, the system will reignite the pilot.
Main Off Setpoint: Temperature at which the system de-energizes the main valves and enters
•
the Pilot state. The main valves will be turned back on when the temperature drops below the
Process Control Setpoint minus the deadband.
Process Control Setpoint: The setpoint about which the process temperature will be controlled.
•
In PID mode, the TCV will be actuated in relation to this setpoint. In Staged Heating mode, the
HFV will be actuated about this setpoint.
Low Temperature Warning Setpoint: If the temperature drops below this trip point the system
•
will display a warning on the user interface and will continue to run.
