SPECIFICATIONS

1.AC LINE PROTECTION - A 100,000 ampere interrupting capacity AC line fuse provides instantaneous protection from peak loads and fault currents. This line fuse is located inside the controller.

2.AUXILIARY CONTACT - A normally-open Form A relay contact, rated .5 ampere @115 VAC and 2A at 30 VDC, is available for external use. The relay energizes when a Run command is initiated, and de-energizes when a Normal Stop command is initiated, the overload monitor trips, or the anti-restart circuit is activated.

3.FIELD SUPPLY - A half-wave or full-wave shunt field supply is available as shown in Table 12;

TABLE 12. SHUNT FIELD DATA

CONTROLLER RATING	SHUNT FIELD VOLTAGE (VDC)		MOTOR SHUNT FIELD LEAD CONNECTIONS
(VAC)
	Half-Wave	Full-Wavea	F1	F2
115	50		F/2	F
		100	F+	F
230	100		F/2	F
		200	F+	F

a. Low inductance motors require a full-wave field to prevent speed instability.
