CAUTION
MACHINE DAMAGE AND/OR PERSONAL INJURY. Never jumper inputs if not previously configured with jumpers as identified on the applicable electrical schematic. Jumpering these inputs will override safety features.
W665
Motor Thermal Protection
On some machines the motor is equipped with a thermal protection switch. Switch inputs are placed between TB3-24 and TB3-25. If an over-temp occurs, the switch is opened triggering a drive fault indicator light to illuminate. If no thermal switch is present, the connections are jumpered. This input can be viewed in the Input Status parameter. For normal operation, logic input for “Motor Temp” remains “1”. If the logic input is “0”, a jumper is missing or an over-temp condition exists with the motor.
Allen-Bradley 1336-Series AC Drives
Fault Indicator Light
The A-B 1336 is equipped with a mechanical relay which transitions when a drive fault occurs. Some machines use this contact for lighting an external indicator light. This relay is used to switch the neutral (AC common) lead to the fault indictor light and connects between TB3-13 and TB3-14. Refer to Figure 50.
