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. A molded-
case, magnetic-trip circuit breaker (Option 1010) is available for Model 2601 Controllers, which provides
a manual disconnection to the controller, and also provides automatic instantaneous trip protection from a
peak load.
2. AUXILIARY CONTACT - A normally-open Form A relay contact, rated 5 ampere @115 VAC and 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 acti-
vated.
3. CONTROL VOLTAGE - A transformer coupled 24 VDC power supply isolates all magnetic control
logic and operator controls from the AC power source for operator protection.
4. DIP SWITCH SETTINGS - A 7-position DIP Switch (S3) is used to program the controller for various
applications as shown in Table 13.
