63_SMPL PUMP STOP OFF
Sample Pump stopped with its rotation
sensor OFF or the sensor is faulty and
it is not sensing the rotation of the
pump. OFF state = LED 15 off (Signal
PCB).
Run the Sample Pump and check
the rotation.
Change Relay 2 on Relay PCB.
Check pump sensor signal looking
at LED 15 on Signal PCB and
DI04 in Digital Input menu.
For further tests, see information
sheet “TT001. BioTector Sample
Pump Stop On & Off Warning_Quick
Troubleshooting” supplied in the
MMC/SD card, shipped with the
BioTector.
Replace the pump.
64_ACID PUMP STOP ON
Acid Pump stopped with its rotation
sensor ON or the sensor is faulty and it
is always showing ON.
ON state = LED 16 on (Signal PCB).
Run the Acid Pump and check the
rotation.
Check pump sensor signal looking
at LED 16 on Signal PCB and
DI05 in Digital Input menu.
Replace the pump.
65_ACID PUMP STOP OFF
Acid Pump stopped with its rotation
sensor OFF or the sensor is faulty and
it is not sensing the rotation of the
pump. OFF state = LED 16 off (Signal
PCB).
Run the Acid Pump and check the
rotation.
Check pump sensor signal looking
at LED 16 on Signal PCB and
DI05 in Digital Input menu.
Replace the pump.
66_BASE PUMP STOP ON
Base Pump stopped with its rotation
sensor ON or the sensor is faulty and it
is always showing ON.
ON state = LED 17 on (Signal PCB).
Run the Base Pump and check
the rotation.
Check pump sensor signal looking
at LED 17 on Signal PCB and
DI06 in Digital Input menu.
Replace the pump.
67_BASE PUMP STOP OFF
Base Pump stopped with its rotation
sensor OFF or the sensor is faulty and
it is not sensing the rotation of the
pump. OFF state = LED 17 off (Signal
PCB).
Run the Base Pump and check
the rotation.
Check pump sensor signal looking
at LED 17 on Signal PCB and
DI06 in Digital Input menu.
Replace the pump.
81_ATM PRESSURE HIGH
System atmospheric pressure sensor
reading is above 115kPa. Therefore,
the sensor reading is defaulted to
101.3kPa fault operation mode.
Check ADC[8] in Analog Input
menu, which should be ~4 Volts.
Faulty pressure sensor.
Replace the motherboard.
82_ATM PRESSURE LOW
System atmospheric pressure sensor
reading is below 75kPa. Therefore, the
sensor reading is defaulted to
101.3kPa fault operation mode.
Check ADC[8] in Analog Input
menu, which should be ~4 Volts.
Faulty pressure sensor.
Replace the motherboard.
83_SERVICE TIME
The service counter has counted down
the days between service intervals and
indicates that service is required.
Service the BioTector.
After service, acknowledge the
warning by resetting the counter
using the “RESET SERVICE
COUNTER” function in
Diagnostics, Service menu.
