SETUP AND DRIVE OPERATION

INTRODUCTION AND GENERAL DESCRIPTION

This controller and drive system when coupled with a MASTERFLEX®L/S®compati­ble pump head provide variable-flow fluid transfer. The motor and controller can be
mounted in separate locations for better protection or control. The NEMA rated
motor and controller withstand wet or hostile environments. Operate the pump
drive manually or remotely via a 4-20 mA input signal.

VARIETY OF PUMP HEADS ACCEPTED

Mount up to 2 MASTERFLEX®L/S®pump heads and all MASTERFLEX®L/S®–compati­ble pump heads. See individual pump heads for flow rates.

SETUP AND DRIVE OPERATION

1. Unpack the drive, save packing material until proper product operation has
been verified.

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

3. Connect the drive motor cable to the cable from the controller.

4. Connect the AC power input line cord to the AC receptacle.

5. Selecting motor direction turns pump on. The LED indicator turns RED.

6. Adjust flow rate with speed control potentiometer.
