If “TRAP SAMPLE” is selected for “TIMED SAMPLING”, the operator
will be prompted to program the amount of trap time.
Boiler OFF time
Boiler Blowdown time
The “TRAP TIME” allows for a delay period before the controller
reacts to the conductivity readings. At the beginning of the trap, the
motorized blowdown valve is closed. The controller then counts down
the programmed “TRAP TIME”. At the end of the “TRAP TIME” the
control then reads the conductivity and reacts on it. This delay, or “TRAP
TIME”, allows any ‘ashed’ boiler water or steam to be re-compressed.
This eliminates any erroneous conductivity readings from ashed steam.
