Page 5: Precautions
Refer to Safety Data Sheets (SDS) precautions from your solution supplier. Water Pre-Prime All LMI pumps are pre-primed with water when shipped from the factory. If your solution is not compatible with water, disassemble the Pump Head Assembly. Thoroughly dry the pump head, valves, O-rings, balls and diaphragm. - Page 6 PRECAUTIONS Back Pressure/Anti-Syphon Valve If you are pumping downhill or into low or no system pressure, a back pressure /anti-syphon device should be installed to prevent over pumping or syphoning. Contact your LMI distributor for further information. Electrical Connections WARNING: To reduce the risk of electrical shock, the metering pump must be plugged into a properly grounded grounding-type receptacle with ratings conforming to the data on the pump control panel.
- Page 7 PRECAUTIONS Flow Display The accuracy of the flow value as shown on the pump display is highly dependent on the specific application. Calibration is necessary in order to display an accurate measure of the flow. Spills CAUTION: Spills of Dangerous chemicals should be cleaned up immediately.

OPERATION 4.0 Enhanced Control Operation This manual covers features supported in the enhanced control model Excel™ XR Series pumps. Enhanced control features are driven by a variety of external inputs and outputs. Please see section 5.0 Cable Wiring for information on connections, signal types, and requirements. -
Page 11: Pulse Mode
OPERATION Press Left or Right to navigate to the parameter entry boxes. Enter the desired flow rates and currents at points P1 and P2. The range of allowable values for flow rate are from zero to the maximum capacity of the pump. Input signal current can range from 0.0 to 20.0 mA. -

Page 13: Batch Mode
OPERATION press Exit to exit without modifying the parameters. For devices with pulse widths less than 4mS, use digital input DI1. In pulse mode, when the pump receives a pulse stream, the calculated flow output value will be displayed. The Start / Stop button must be pressed or Remote Start / Stop activated for the pump to dose at the calculated flow rate. -
Page 14: Cycle Timer
OPERATION 2. Enter the values for the quantity and units of the volume of fluid to be dosed (Figure 6). NOTE: If a set of entered values results in a condition that exceeds the pump’s maximum calibrated flow, the field will be highlighted red. Increase or decrease this or one of the other parameters to clear the condition. -

Press Left and Right to navigate and the Up and Down buttons to set start time, duration and flow rate. -
Page 18: Inputs
OPERATION 4.6.1 Inputs Enhanced control model pumps have four digital and two analog configurable inputs. Digital inputs are labeled DI1 – DI4. Analog inputs are AI1 and AI2. See section 5.0 Cable Wiring, for the cable and pin assignments for each of these inputs. Each digital input can be assigned to one of five functions or <Disable>. -
Page 19: Analog Tank Level Input
OPERATION 4. Press Save and Exit Internal Mode External Mode Figure 11: Int/Ext Select With the selections shown above, the input configured per section 4.6.1.3 Configuring Enhanced Control Inputs, and cable hookups per section 5.0 Cable Wiring, a Remote Internal/External signal will toggle the pump between manual and analog modes. 4.6.1.2 Analog Tank Level Input Selecting this input overrides the digital tank level empty and tank level low inputs and combines both functions into one analog signal. -
Page 20: Outputs
OPERATION Digital Inputs 1-4 Analog Inputs 1-2 Figure 12: Configure Input In the Settings screen, navigate to configure input and press Enter . Press Left and Right to navigate between fields and the Up and Down buttons to make selections. Each input can be identified as NO (normally open) or NC (normally closed). If testing produces the opposite effect from what is desired, frequently an easy solution is to change the switch type from NO to NC or vice versa. -

4. Suction tubing is curved or coiled in 4. Suction tubing must be vertical. Use tank LMI ceramic weight supplied with pump (see section 3.4 Foot Valve / Suction Tubing Installation) 5. Fittings are overtightened 5. DO NOT OVERTIGHTEN FITTINGS! - Page 28 TROUBLESHOOTING 5. Fittings are over tightened 5. DO NOT OVERTIGHTEN FITTINGS! This causes seal rings to distort and not seat properly which caused pump to leak back or lose prime 6. Air trap in suction valve tubing 6. Suction tubing should be as vertical as possible.
