ELECTRICAL DATA
TO DETECT OPEN AND SHORT CIRCUITS IN ELECTRICAL COMPONENTS.
Open circuits in the coils of electrical components may be detected by isolating the coil and checking for continuity with an ohm-
meter or with the unit in series with a light or bell circuit.
Shorted turns are indicated by a current draw substantially above normal (connect ammeter in series with suspected element
and impose normal voltage) or D.C. resistance substantially below normal. The current method is recommended for coils with
very low D.C. resistance.
Motor current draw in the stator should be measured with the rotor in place and running. Brake, relay and contactor coil current
should be measured with the core iron in operating position.

*Resistance values listed are nominal and they may vary slightly from component to component.
**On dual voltage units (230/460-3-60, 220/380-3-50 and 220/415-3-50), brake coils operate on 230 (220) volts.
