1. On 77301 connect Motor Cable plug to mating receptacle on the Controller.

2. Mount pump head and load tubing. (See pump head manual.)

3. Connect power cord to Controller and grounded power line outlet.

4. Turn pump on and select tubing SIZE.

NOTE:

If CAL LED is lit, that tubing size has been previously field calibrated. If LED is not lit, the drive is operating

with the built-in factory calibration. To clear a field calibration, press and hold the CAL switch until the CAL

light goes out. This will take about 3 seconds. To recalibrate for better accuracy, see Calibration section.

5. MODE selection (INTernal, mA, or V).

6. Select pump DIRection (CW or CCW).

7. PRIME and CALibrate the pump (if required).

8. Press FLOW key and watch display to set the flow rate with UP/DOWN (▲, ▼) arrow keys.

9. Press STOP/START key to begin pumping.

NOTE:

When in INTernal mode, pump will not restart automatically after a brownout or powerout condition unless

operator changes default condition. In mA or V modes, pump will start with a non-zero mA or V signal.

Automatic Start Enable/Disable (INTernal mode only)

Press and hold STOP/START on power-up. After five (5) seconds, display will change to all dashes. Then, while

holding STOP/START, press PRIME five (5) times. Display will flash "ON" or "OFF". Use UP/DOWN (▲, ▼) arrow

keys to set automatic start option. Press any other key to exit. When "ON" is selected, pump will start automatically

at power-up if it was "ON" when powered down.

Use only MASTERFLEX precision tubing with MASTERFLEX pumps to ensure optimum performance.

1. Select correct tubing size and flow rate.

2. Press CAL, calibration volume appears and CAL LED flashes.

3. Press STOP/START, the pump will use its current calibration to dispense the specified calibration volume. The

pump will stop automatically.

4. Weigh/measure the sample.

5. Use UP/DOWN (▲, ▼) arrow keys to correct the flashing volume display.

NOTE:

If the adjusted calibration is too great, "Err" will appear in the display. If this occurs, press the CAL key and

repeat the calibration procedure. The microprocessor will retain one special calibration value per tubing

size, even when power is turned off. The next calibration will replace the existing value.

6. Press SIZE to exit the calibration cycle.

NOTE:

After calibration, the maximum and set flow rates will change due to the new calibration. If these change by

more than 10%, better accuracy can be obtained by setting the desired flow rate and repeating the

calibration.

Maximum Flow Rate ("OTH(ER)" Tubing only)

1. To set the maximum flow rate for non-standard pump heads or tubing sizes, select the OTH(ER) tube size.

2. Press CAL and then FLOW. The maximum flow rate will then flash on the display.

3. Use UP/DOWN (▲, ▼) arrow keys to set desired maximum flow rate.

4. Press SIZE to exit.
