4.2 VALIDATION MONITOR /PRO KIT ALARMS (OPTION)
20
COLUMN PRESSURE : OUT OF
RANGE – LOW
Pressure is lower than the minimum set poin
programmed
- Check that the baskets are in the
machine or that the rack ports are
capped accordingly.
- Check that the pump operates
- Check the door switches
- Check the transmitter calibration.
- Check the foaming issues within the
chamber
21 COLUMN PRESSURE : UNEXPECTED
Pump pressure is above minimum set point
value when pump not running.
- Check the transmitter (look at the
pressure and calibrate it if necessary).
- Check the low limit value for the
pressure alarm. (This value is used for
this alarm).
- Pressure transmitter must give 4mA
when the pump is stopped
22
COLUMN PRESSURE : OUT OF
RANGE – HIGH
Pump pressure is above Max set point value
- Check column piping
- Check the transmitter
- Verify that there is no blockage in the
column.
- Check blocking issues
4.3 CONDUCTIVITYMETER ALARMS (OPTION)
74
FINAL RINSE CONDUCTIVITY :
PROBE DEFECT
Open wire, overrange or underrange
- Verify the probe.
- Check the wire connections.
78 FINAL RINSE CONDUCTIVITY
The final rinse conductivity is higher than the
limit configured in the program settings.
- Check set point.
- Check conductivity probe calibration.
