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;
