CAPSTAN:
The BAM 1020 will rotate the capstan shaft forward and backwards and
will check if the photo interrupter sees the shaft rotating. The Capstan shaft is what
moves the filter tape back and forth.
NOZZLE DN:
The BAM 1020 will attempt to lower the nozzle, and will check if the
nozzle motor has moved to the down position with a photo interrupter. It is possible for
the nozzle to become stuck in the UP position, even if the nozzle motor has
successfully moved to the DOWN position. For this reason, proper inlet alignment and
nozzle O-ring maintenance is necessary.
NOZZLE UP:
The BAM 1020 will attempt to raise the nozzle, and will check if the
nozzle motor has moved to the up position with a photo interrupter.
FLOW:
The BAM 1020 will attempt to turn the pump on, and will then look for output
on the flow sensor. This test takes about a minute and will fail if the pump is not
connected.
TAPE BREAK:
The BAM 1020 will move the supply and take-up motors to create
slack in the filter tape, and look for proper operation of the tensioner photo interrupters.
TAPE TENSION:
The BAM 1020 will tension the filter tape, and then check the
condition of the tensioner photo interrupters.
SHUTTLE:
The BAM 1020 will attempt to move the shuttle beam left and right, and
will check the motion with a photo interrupter.
REF EXTEND:
The BAM 1020 will attempt to extend the reference membrane, and
will check the motion with a photo interrupter.
REF WITHDRAW:
The BAM 1020 will attempt to withdraw the reference membrane,
and will check the motion with a photo interrupter.
3.6 Initial SETUP Settings Considerations
The BAM 1020 comes pre-programmed with a wide array of default values for the settings
which govern the measurement and calibration. Most of these setup values will not be
changed, since the default values are correct for most applications. Review the Setup Menus
in Section 6 of this manual and decide if any values need to be changed. At the very least,
review the following parameters:
1. Set the system clock in the SETUP > CLOCK menu. The BAM 1020 clock may drift as
much as two minutes per month. It is important to check the clock at least once per
month to ensure the samples are performed at the correct times.
2. Review the BAM SAMPLE, COUNT TIME, MET SAMPLE, RANGE, and OFFSET
values in the SETUP > SAMPLE menu.
3. Review the FLOW RATE, FLOW TYPE, CONC TYPE, and HEATER CONTROL
settings in the SETUP > CALIBRATE menu.
4. Review the scaling of any external sensors in the SETUP > SENSORS menu.
5. Review the Smart Heater control settings in the SETUP > HEATER menu.
