    Your carton will contain the items shown in Figure 1. Please notify the carrier immediately if there are any signs of damage to the Controller or its parts. Contact your LMI Distributor if any of the parts are missing. There is a number label on the inside cover of the unit; for easy reference, you should note the model and serial numbers on the front cover of this instruction manual.

  • Page 6: Electrical Installation

    Electrical Installation ELECTRICAL CONNECTIONS To reduce the risk of electrical shock, the control or metering pump must be plugged into a grounded outlet with ratings conforming to the data on the control panel. It must be connected to a good ground. DO NOT USE CAUTION ADAPTERS! All wiring must conform to local electrical codes.

    3.2.2 Field Wiring Instructions Typical US field installation would find a 6 ft (2 m) AC cord wired and two (2) 1 ft (30 cm) AC receptacles (On/Off mode) or two (2) 10 ft (3 m) pump drive cables (Proportional mode) installed. A BNC receptacle would be installed for the ORP probe.

  • Page 9: Orp Adjustment Pump(S)

    Install and calibrate the pumps according to the manufacturer’s recommendations. In the Proportional Output mode, the DR5000 ORP Controller will operate any LMI Series A9, A7, B9, B7, C9, C7, E7 or L7 pump, or any other pump which operates by providing direct proportional response to a modulated pulse input signal.
  • Page 10 KEYS: This key is used to set up the control profile for the reducer dosing pump (holding the key for five (5) seconds will allow priming of Pump A) (Factory setting 90 SPM). This key is used to set up the control profile for the oxidizer dosing pump (holding the key for five (5) seconds will allow priming of Pump B) (Factory setting 65 SPM).

  • Page 11: Operation

    OPERATION In the default mode, as shipped from the factory without any extended features programmed in the ‘menu’, the controller is set to operate two dosing pumps towards a single desired ORP region as defined by the set points. It will do this in one of two ways, On/Off or Proportional, shown graphically below: On/Off Control Proportional...

  • Page 12: Proportional Mode

    Proportional Mode The unit is shipped pre set at the factory for the Proportional or On/Off mode. To change the unit to the opposite mode see ‘Advanced List,’ Option 2, on page 20. Pump A Control Profile Controller must be in Off mode to program changes.

  • Page 13: On/Off Mode

    (9) ..Pump B (Oxidizer Pump) is programmed in a similar way. If ‘Point 3’ is selected in the Advanced Features menu, the user will be prompted to enter a ORP value for Set Point 3 and a Pump Speed at Set Point 3. On / Off Mode (50 mV) Pump A Control Profile...

  • Page 14: Alarms

    It is highly recommended that the hysteresis (pump off function) be used to prevent relay chatter. The function of the hysteresis is to prevent pump relay chattering. It operates by allowing the pump to be turned on when the control point plus (or minus) the hysteresis value has been met, but does not allow the pump to turn off until the control point has been met.

    (8) ..Press again to program the 4-20 mA output for Point 1. (9) ..Press to select the mV value for Point 1 mA output. Default is: 4 mA = - 1000mV 20 mA = +1000 mV (10) ..Press again.

  • Page 16: Performing A New Calibration

    Performing a New Calibration For two point calibration, the default settings are Buffer 1 = 80.0 mV and Buffer 2 = 400 mV; but these values may be changed. The calibration parameters (buffer mV and one or two point calibration) of the previous calibration are the initial values for the current calibration.

    (6) ..Press again and the symbol will prompt you to put the probe in Buffer 2. Wait for the mV value to settle. (7) ..Press again. This will accept the second calibration value and will display the mV/mV and % Slope result of the calibration.
  • Page 18 Setting Timers The unit must be in the Off (edit) mode to change the timer settings. (1) ..Press the key to view the run time for Pump A. (2) ..Use to adjust to desired maximum run time. The ‘hr : min’ will change to ‘min : sec’ automatically as the run time is reduced below 1 hour. (3) ..
  • Page 19 (7) ..Press key to advance to Response Rate. This is programmed in D ORP units. The smoothing of the input signal is determined by D ORP time. The following values can be programmed (min : sec): 00 : 01, 00 : 10, 00 : 20,..04 : 00 (In increments of 10 seconds) When 00 : 01 is programmed the controller responds to a change in input in one (1) second.
