Activation Conditions
The circuit current draw is outside the normal range.
Unit Behavior
Pretrip will fail in Test #2 and display “PRETRIP FAIL AND COMPLETED”.
Reset Conditions

Corrective Actions
1. Check Coil a. Inspect coil and connector pins and terminals. Verify no damage to coil. Verify no damaged or corroded pins. b. Check resistance of coil. Refer to Section 1.11 for specifications. c. Use Component Test mode (Refer to Section 1.2.4) to test actual current draw of the circuit. Refer to Section 1.11 for specifications. Verify that the actual current is within specifications. 2. Check Power and Wiring a. Use Component Test mode (Refer to Section 1.2.4) to energize circuit. Check for power at CLH terminal A and 3MM-11. Minimum 11 VDC. If not, check connectors and wiring between terminals. Verify no damage, moisture or corrosion. b. Check for ground at CLH terminal B (including SP-3) to GND 1RING1. Good ground. If not, check connectors and wiring between terminals. Verify no damage, moisture or corrosion.
