E7000/E7500/E8000 IOM Manual I. GENERAL INFORMATION A. Unpacking and Inspection Your E7000/E7500/E8000 ANALOG TRANSMITTER is engineered to be a highly reliable, accurate system. It has been systematically assembled, inspected, tested and calibrated; then carefully packed or installed on your new McCrometer flowmeter before shipment. If not installed, unpack the transmitter carefully and inspect each assembly thoroughly for obvious shipping damage (Figure 1).

The electronic circuits are of solid state technology but damage can result from shock in a fall. During unpacking and installation avoid dusty areas as much as possible. Fine dust or sand can cause erratic operation or failure of the circuitry.

E7000/E7500/E8000 IOM Manual III. INSTALLATION A. Disassembly It is necessary to remove the existing canopy and register. The analog transmitter mounts between the register and the register mounting plate already installed on top of the pipe protruding from the top of the meter. * Note: If your meter has the old style plastic canopy and gasket you must replace both the canopy and the base plate with new aluminum ones (Order Canopy Kit RO143-00).
E7000/E7500/E8000 IOM Manual B. Re-assembly 1. Analog Transmitter Installation E7000 TRANSMITTER O - RING FLAT GASKET MOUNTING PLATE Figure 7. Installation Of The Transmitter Cleanliness is vital for the operation of the transmitter and the register. Check the threaded area and the mounting plate, Figure 7, they should be free of grease, dust, or any other foreign materials. Place the o-ring and flat gasket over the lip on the mounting plate. Use a small amount of oil to lubricate the oring.
E7000/E7500/E8000 IOM Manual 2. Canopy Installation CANOPY The canopy can now be installed. Check the transmitter housing and the canopy for cleanliness and clean if needed, Figure 8. Orient the canopy and lower it carefully over the lubricated o-ring and seat it firmly onto the Transmitter Housing. Again, be careful so that the o-ring on the transmitter housing is not damaged. SCREW O - RING Locate the long screws; insert the screws through the canopy, transmitter housing, and the Plate.
E7000/E7500/E8000 IOM Manual 3. Connect the external power and loads to the terminals in the condulet as follows: a. Connect the positive (+) lead from the external power supply to the terminal with the RED wire connected inside the condulet, and the negative (-) side of the power supply to the negative side of the LOAD, then connect a wire from the Positive side of the LOAD to the BLACK wire inside the condulet as shown in Figure 10.
E7000/E7500/E8000 IOM Manual IV. TROUBLESHOOTING OPERATION The transmitter was designed as a fully functional integrated system depending only on an external power source. It is composed of one circuit board with several different functions. The magnet drum rotates on the shaft, which passes by the sensor that produces a pulse which is then transformed into a square wave and goes to the directional sensor.
E7000/E7500/E8000 IOM Manual Table 1 has a list of conditions, things to check, possible causes of the troubles, and what to do to correct the problems. Table 1. Troubleshooting CONDITION CHECK No output Power supply. POSSIBLE CAUSE Wrong power supply.
E7000/E7500/E8000 IOM Manual V. CALIBRATION IMPORTANT: Allow the mA output to stabilize for 1-2 minutes when the unit is first powered up before reading or changing output values. It is necessary that you be able to rotate the magnet in the transmitter at a controlled rate and read the current output. The following list of equipment is meant as a reference only, but is the equipment we use in our electronics department at McCrometer.
E7000/E7500/E8000 IOM Manual C. Calibration 1. With the motor at zero RPM, adjust the potentiometer farthest to the left end of the E7000 circuit board to read 4.0 mAdc on the multimeter, see Figure 14. ZERO SPAN Figure 14 Calibration Of Zero and Span 2. Apply power to the speed control system that you are using and set for Full Scale RPM. 3. Adjust the pot on the right hand side for a reading of 20 mAdc on the multimeter. 4. Stop the rotation of the magnet and check the 4 mAdc reading.
E7000/E7500/E8000 IOM Manual VI. WARRANTY This Warranty Shall apply to and be limited to the original purchaser consumer of any McCrometer product. Meters or instruments defective because of faulty material or workmanship will be repaired or replaced, at the option of McCrometer, free of charge, FOB the factory in Hemet, California, within a period of one (1) year from the date of delivery.
