L/S Precision Variable-Speed Console Drives Operating Manual 1-1 Section 1 Introduction C Controls, Indicators and Connectors D B E G F A Figure 1-1. Controls, Indicators and Connectors A. POWER (ON/OFF) SWITCH: Turns the unit ON or OFF. B. SPEED KEYS: Sets the speed of the pump. The higher the number, the faster the speed of the pump. When the speed key is depressed the smallest speed units change first followed by an increasing rate of change. C. FLOW DIRECTION KEY: Sets the direction of pump rotation Clockwise/Counterclockwise. An LED annunciator indicates the active direction. The motor is brought to a controlled stop before reversing direction. D. INTERNAL/EXTERNAL KEY: Changes the drive operation mode. Internal (Local) operation from the front panel keypad is designated by INT, external (Remote) operation is designated by EXT. In INT mode, START/STOP, FLOW DIRECTION, and SPEED keys on the front panel determine operating state. Depression and release of keys enables toggling between the two operating states. E. START/STOP KEY: Upon depression, key toggles the motor ON/OFF during INT mode. This key will not start the drive if in EXT mode. If pressed while operating in EXT mode (stop desired), the button will always stop the drive and a toggle of the EXT Start/Stop is required to restart the drive. F. EXTERNAL/REMOTE CONNECTOR: Utilized to connect wiring for remote control operation with a DB9 connector. G. IEC Power Entry Module/Line Cord: Utilized to connect line cord to drive. See page 4-1 for alternative cords. 1-2 L/S Precision Variable-Speed Console Drives Operating Manual Masterflex Section 2 Installation and Setup Before Starting Drive • The drive should be mounted on a flat horizontal surface. Up to a maximum of two (2) Pump Heads can be added for 300 rpm and 600 rpm drives or four (4) Pump Heads for 100 rpm drives. • The ambient air temperature should not exceed 104° F (40° C) and adequate air flow should be provided for. • The drives are provided with a grounded plug. If used in a GFCI protected circuit, nuisance tripping may occur. • Tubing should be clean and routed so that bend radii are at a minimum four (4) times the tube diameter and as short as possible. WARNING: Turn drive off before removing or installing tubing. Fingers or loose clothing could get caught in drive mechanism. • Use a tube size of appropriate diameter for the flow rate and viscosity required. • For tubing selection and compatibility, see Tubing Selection Guide within this flash drive or on the web. • For Pump Head information, see Pump Head datasheets within this flash drive or on the web. • Before cleaning or conducting maintenance on unit remove power from the drive. DANGER: High voltages exist and are accessible. Use extreme caution when servicing internal components. Mounting the Pump Head Masterflex Mount Pump Head and load tubing (See Pump Head datasheets within this flash drive or on the web). Check to ensure that rollers are clean and free of defects. L/S Precision Variable-Speed Console Drives Operating Manual 2-1 Section 3 Operation Inserting Tubing WARNINGS: Tubing breakage may result in fluid being sprayed from pump. Use appropriate measures to protect operator and equipment. Turn Pump System off before removing or installing tubing. Fingers or loose clothing could be caught in the pump mechanism. CAUTION: To avoid electrical shock, the power cord protective grounding conductor must be connected to ground. Not for operation in wet locations as defined by EN61010-1. If the product is not used in a manner specified in the instructions, the protection provided by the equipment may be impaired. Tubing Inspection and Replacement Tubing should be inspected periodically for tears, cracks, cut marks, abrasions, inability to hold pressure, bubbles in the flow stream and reduction or loss of flow. Tubing life may be extended by periodically moving the worn tubing inside the occlusion bed of the pump to the outside of the occlusion bed to the suction side of the pump. This will avoid excessive tubing wear at any specific point. Always move the worn tubing to the suction side of the pump. Pump Controls CAUTION: When changing flow direction, allow the pump to come to a complete stop before starting again. Failure to do so could cause permanent damage to the motor. 1. Make sure the speed is set to the minimum setting. 2. Turn the power switch ON. Increase the speed to start the pump action. The higher the rpm setting, the faster the speed of the pump. 3. The L/S Precision Variable-Speed Console Drives are self-priming. To begin pumping, select a flow direction with the flow direction button, insert the intake and output tubing into a reservoir, and turn the unit ON. Prime the tubing for at least 5 minutes. If accurate flow control is important, allow the pump to prime for approximately 20 minutes for more stable flow conditions. Masterflex L/S Precision Variable-Speed Console Drives Operating Manual 3-1 Section 3 Operation Keypad Lockout Enable/Disable Press and hold the INT/EXT key. After five (5) seconds, display will change to all dashes. Release INT/EXT key and press UP ARROW key (▲) five (5) times. Repeat this process to unlock the keypad. When the keypad is locked out, display will change to display all dashes (- - - - -) when a key is depressed. External Operation Models are equipped with inputs that can be controlled by external signals connected at the rear panel 9-pin “D” shell connector. The external inputs permit control of the pump by remote equipment or accessories. Figure 3-1 indicates the signal locations in the connector. Note: Jumpers “A” and “B” are optional. See page 3-3 External Inputs for correct usage. Pin No. Description 1 Speed Control Voltage Input (0–10V) (+) input 2 Speed Control Current Input (4–20 mA) (+) input 3 Speed Control Input Reference Common 4 Local/Remote Speed Control 5 Local/Remote Speed Control Reference 6 Start/Stop and CW/CCW Reference 7 Start/Stop (+) Control 8 CW/CCW 9 Chassis (Earth) Ground Figure 3-1. DB9 Pin Configuration with Wiring Scheme 3-2 L/S Precision Variable-Speed Console Drives Operating Manual Masterflex Section 3 Operation External Inputs The front INT/EXT key enables external functions. Switching to INT on the display disables the external functions, allowing the front panel controls to operate the pump. When the INT/EXT key is in the EXT position, starting and stopping the pump is controlled by an external contact closure between pins 6 and 7 (Jumper B), and the pump speed is determined by an externally supplied 0–10V or 4–20 mA source. Connection must be made between pins 6 and 7 to Start/Stop the drive and a control voltage greater than 0V between pins 1 and 3 or a control current greater than 4 mA between pins 2 and 3 must be applied for the pump to run. If setting the speed from the front panel is desired with external Start/Stop contact operation, the INT/EXT key must again be in the EXT position. In addition, Jumper A should be in place. Jumper A connects pin 4 of the “D” shell connector (Local/Remote) to pin 5 (Local/Remote Reference). Start/Stop will then be controlled from the rear panel (Jumper B), and the pump speed will be controlled from the front panel. The accessory Footswitch (part no. 77595-35) and Handheld Remote Controller (part no. 07528-80) are connected internally in this way. NOTE: The signal common for the speed control voltage and current inputs is not referenced to earth ground. The START/STOP (pin 7), CW/CCW (pin 8) and Local/Remote (pin 4) are digital inputs. They are internally pulled up to +5 V with respect to earth ground via pins 5 and 6. They can alternately be driven with open collector logic. For increased noise immunity, use of contact closures is recommended.
