Limit Sensor Calibration (Excludes 30D) - Teledyne D series Installation And Operation Manual

9.14.4 Limit Sensor
Calibration
(Excludes 30D)
Section 9 Pump Maintenance, Troubleshooting, and Servicing
Once the new limit sensor assembly is installed, the sensors
must be calibrated. Before calibrating the limit sensors, be sure
the cylinder is unscrewed several turns. Follow steps 8-10 in the
previous section (9.14.3). Use the following procedure to calibrate
the limit sensors:
1. Connect the pressure cable and power cord and turn the
controller ON.
2. Press REFILL and enter the maximum rate.
3. Press STOP when the interrupter flag is approximately
from the full (lower) sensor.
4. Press 'A' (FLOW RATE), and use the number key to set 10
(ml/min). Press the ENTER key.
5. Press REFILL.
After the lower limit sensor is interrupted, the motor will
stop.
6. Press CONST FLOW.
7. Press 'A' (FLOW RATE) and select MAX.
8. Press RUN.
9. Press STOP when the volume counter in the upper
right-hand corner of the LCD reads 005.00 ml or less.
10. Press 'A' (FLOW RATE) and enter 5 ml/min.
11. Press RUN .
12. Press STOP when the counter reads 000.30 or less.
13. Press 'A' (FLOW RATE) and enter 1 ml/min.
14. Press RUN.
15. When the counter counts from 000.01 to 000.00, press
STOP.
16. Lower the upper limit sensor to the point where the flag
just interrupts the sensor. ("CYLINDER EMPTY" will
flash on the screen.)
17. Tighten the top upper limit mounting screw.
18. Turn the controller to STANDBY and disconnect the pres-
sure cable.
19. Screw the cylinder into the cylinder mounting block until
the cylinder bottoms firmly against the stop ring in the cyl-
inder mounting block (the cylinder will no longer turn). Do
not overtighten.
20. Unscrew the cylinder a minimum of
the inlet and outlet ports as you had them before. Do not
unscrew the cylinder more than one full turn from the stop
position.
21. Lock the cylinder by tightening the locking screw.
22. Connect the pressure cable and power cord and turn the
controller ON.
23. Press REFILL. Wait until you have access to the second
upper limit sensor mounting screw and tighten it.
