4.3  Trouble-Shooting

Localization of electrical malfunction in the 10DX3111 Magnetic Flowmeter can best be accom-
plished by making static and dynamic measurements on the meter in question and comparing rhe
results with the proper resistance and voltage measurements given in Table 4-1.  Only qualified
electronic technicians should be permitted to service the meter.

WARNING

Equipment powered by an AC line voltage presents a potential electric

shock hazard to the user. Make certain that the system power input

leads are disconnected from the operating branch circuit before

attempting electrical interconnections or service.

4.3.1  Magnet Coils

To check the magnetic coils follow this procedure:

1) Power down the converter/driver.  Remove the coil wiring from terminals M1 and MR in
the converter/driver. (See converter/driver instruction bulletin for location of terminals.)

2) Measure the resistance; the cable resistance should be as indicated in Table 4-1 (or
more depending on the length of the interconnecting cable).

3) Check for short circuit between either of these wires and terminal 3 on the con-
verter/driver.  Continuity indicates a shorted magnetic coil.  If a shorted coil is detected, the
meter must be replaced.

4) Reattach coil wiring.
