Calibrate Foam Concentrate Pump (Password Code 1112)
This foam proportioning system is compatible with any foam concentrate within the limits determined by
performing this calibration procedure.
To accurately calibrate the foam concentrate pump and control module for specic types of foam concentrate
this calibration procedure must be performed. The concentrate foam pump should be re-calibrated if the foam
concentrate is changed to a different type.
The system is tested and calibrated to factory standard settings. If necessary the factory standard
calibration settings can be restored with program codes P301 foam A and P302 foam B. (Refer to
Restore Factory Foam Concentrate Pump Flow Calibration.)
Overview
No water is used to perform this procedure and the foam concentrate that is pumped is collected, accurately
measured, and returned to the tank.
A simulated discharge water ow rate is entered by the operator along with the desired foam percent. The
system pumps foam concentrate at the correct rate based on the simulated water ow and percent selected.
The system simulates water ow (ow rate is selected by the operator) and pumps foam concentrate.
The concentrate is routed through the calibration bypass valve where it is collected to be measured. The
control module message display shows the calculated foam concentrate the system has pumped.
The amount collected is measured and compared with amount shown in the display. Adjustments to the
values shown are made if necessary.
Note: Dual foam systems have two calibration programs for A foam and B foam. This allows the two
different concentrates to be calibrated accurately. Single foam systems must have the control module
programmed for the correct type of foam A or B (program code P312). This is veried in step 1.
Set-up
Supply power to the system, OFF is shown in the FLOW display.
For systems with multiple foam tanks select the A or B tank.
TFC400 Only:
1. Press the ON/OFF and PRESET buttons at the same time and hold.
Results: MANUAL MODE ashes in the message display for 3 seconds.
2. Press the A/B button to select the A or B tank.
3. Remove power from the system for 5 seconds to exit manual mode.
4. Supply power to the system, OFF is shown in the FLOW display.
Place a calibrated collection bucket under the calibration bypass valve hose. (The bypass valve is part of
the foam pump assembly.)
Set the calibration bypass valve to bypass.
Note: When calibration is complete, set the calibration bypass valve control back to the operate position
