6-Volt Series:
Use a DC voltmeter of approximately
0-15 volt range . A normal reading is from 5 .5 to 6 .5
volts .
The above checks normally are sufficient . Further
checks may be made as follows: a low range
ammeter, when connected in series with one
magnet lead, will normally indicate approximately
.40 amperes for the 90 volt units, 1 .0 ampere for
the 24 volt, and 3 .5 amperes for the 6 volt series .
These readings are with the power on and the
potentiometer control in the maximum position .
Ohmmeter checks should be made with the power
off and the circuit open (to be certain, disconnect
one lead to the magnet) . Average resistance for the
90 volt series is 220 ohms; for the 24 volt, 20 ohms;
and for the 6 volt series, 1 .5 ohms . A very high or
infinite resistance reading would indicate an open
coil .
If the above checks indicate that the proper voltage
and current is being supplied to the magnet,
mechanical parts should be checked to assure that
they are in good operating condition and properly
installed .
