10D1475 MINI-MAG MAGNETIC FLOWMETER INSTRUCTION BULLETIN

3.2 Turn Power On

ELECTRICAL SHOCK HAZARD. Equipment powered by an AC line
voltage presents a potential electric shock hazard. Servicing of the
Magnetic Flowmeter or Signal Converter should only be attempted by a
Apply system power to the Series 10D1475 Magnetic Flowmeter by closing the external switch or
circuit breaker (not supplied with the meter); there are no master power switches inside of the
equipment. Also energize any auxiliary equipment associated with the flow metering system such as
remote analog recorders, controllers or rate indicators.
Once power is applied, the display should become active. Refer to the 50XM1000N and M2 Con-
verter instruction bulletins for proper display indications and system adjustments.
If not already entered, some parameters must be entered for proper system operation (refer to the
instruction bulletin supplied with the Converter):
• Verify the meter size stamped on the nameplate in the "Size" parameter.
• The range may have been factory-set to 10 m/s. Enter the desired maximum
forward and reverse flow values in the appropriate units.
• Hydraulically ideal range end values are approximately 5-10 ft/sec (or 2-3
m/s).
• Select the desired output current range in the "Submenu Current Output".
• Set the number of pulses per unit, the pulse width and the totalizer mode from
the Totalizer Submenu.
Check the system zero (Refer to Zero Check, Section 3.3 ).

3.3 Zero Check

The system zero must be set at the Converter. For this parameter, all flow activity through the
flowmeter must be totally stopped. Make certain that the meter pipe of the primary is totally full of
fluid. The zero can be set either manually or automatically at the Converter by accessing the
parameter "System Zero". Refer to the instruction bulletin supplied with the Converter for the
appropriate procedure.

3.4 Detector Empty Pipe (option)

The empty pipe module, when installed, should be adjusted at start up under actual conditions. Refer
to Instructions in the Converter instruction bulletin. (Not available for integral configuration)

3.5 Start Process Flow

Start flow through the process piping system that includes the meter. Allow a nominal flow through
the pipeline for several minutes to purge entrapped air. The pipeline must be full for accurate flow
measurement. Flow measurement, display and concurrent output signal transmission will commence
with process flow through the meter.
3.6 EEPROM (units with M2 Converter only)
All parameter values are stored in the main EEPROM located on the main board assembly under the
Controller electronics module. If replacing the Primary in a remote system, remove the original
EEPROM from the Controller and replace it with the EEPROM supplied with the replacement
Primary. Follow "Load" or "Store" data menu procedures (whichever is applicable) detailed in the
Converter instruction bulletin. On power-up, all data will be accepted and need not be entered again.
After all parameters have been set and entered they should be saved in the
external EEPROM, refer to the "Load" & "Store" menu commands in the
3-2
