Procedure 5.1 - Measuring The Resistance Of An Eddy Current Magnet - Precor EFX5.31 Instruction Manual

Procedure 5.1 - Measuring the Resistance of an Eddy Current
Magnet
Caution
Remove power from the EFX before you measure magnet resistance.
Procedure
1. Set the on/off switch in the "off" position, then unplug the power cord from the wall outlet.
WARNING
Before continuing with this procedure, review the Warning and Caution statements listed in
Section One, Things You Should Know.
1. Remove the rear covers as described in Procedure 7.1.
2. Set the ohmmeter to a range that will conveniently read up to 125Ω.
3. Disconnect the J1 (magnet) connector from the lower PCA. Measure the resistance
between the two terminals of the connector removed from the lower PCA. See Diagram 6.5.
Diagram 5.1 - Eddy Current Magnet
Note:
The resistance of the magnets will be higher than optimum (90 - 110 Ω) when they are warm.
4. If the resistance measures significantly low or open, replace the magnet per Procedure
7.13.
5. Re-install the rear covers as described in Procedure 7.1.
6. Set the on/off switch in the "on" position. Thoroughly test all functions per Section Four.
