AVS 800-372-7402 AVS-1700-ACX Logic module

The following troubleshooting guide is an aid in isolating trouble to the control box, actuator, plant wiring, or elsewhere. The guide assumes that the system wiring, soldering connections, switch and relay contacts, and input and output connections are correct and in good working order. Make the checks in the order indicated. The wrong voltage can damage the control. When replacing a control, check the power supply, battery, etc., for the correct voltage as indicated on the name tag on the control. Both high-voltage and low- voltage models of 2301A speed controls are available. The lowvoltage model will be damaged if connected to a high-voltage supply. The high-voltage model will not operate with a low-voltage supply.

Prime mover will not start. 

Actuator not moving to start-fuel position. DC supply voltage polarity reversed, no supply voltage, or supply voltage is low. Check for supply voltage within limits indicated on control name tag. Reverse leads if dc polarity is incorrect.If there is a voltage output at terminals 9 and 10, but the actuator does not move, the wiring to the actuator should be checked for opens or shorts. With the EG3P actuator, remember that terminals C and D of the mating plug must be jumpered. Coil resistance in a Woodward actuator with terminals 9 and 10 disconnected, is about 35 Ω.

Start fuel limit set too low.

 Turn start fuel limit cw until prime mover starts. Check actuator and linkage for proper installation and operation. Problems may be oil supply, direction of rotation, insufficient drainage, linkage, worn actuator components, or improper adjustment
