What to do if Woodward APECS DPG-2101-001 engine takes too long to reach the set speed?
If your Woodward Controller engine takes too long to reach the set speed, the integral setting might be too low, so you should improve PID tuning. Also, the Startup Rate setting, Accel Rate setting or Speed Filter setting might be too low.
What to do if my Woodward APECS DPG-2101-001 LED display does not light up when powered?
If the LED display on your Woodward Controller doesn't light up when powered on, check the following: Ensure the BAT + and BAT – leads are not reversed by checking the wiring. Verify that the battery voltage measures between 9–30 Vdc. If these steps don't resolve the issue, the controller may be defective and need replacement.
Why won't my Woodward APECS DPG-2101-001 Controller engine start?
If your engine won't start with the Woodward Controller, consider these potential causes: Check if the actuator leads are connected or shorted. Ensure there is a fuel source and turn it on if necessary. Charge or replace the battery if the voltage is low. Increase the set speed if it is lower than the crank speed. Adjust the magnetic pickup (MPU) gap to ensure the MPU speed signal is present and reads a minimum of 2.0 VRMS. As a last resort, restore all parameter values to factory default settings and crank the engine again.
What causes sluggish response to load changes in my Woodward APECS DPG-2101-001 Controller?
A sluggish response to load changes in your Woodward Controller can be caused by a gain that is too low. Improve PID tuning to resolve this issue. Also, check if the speed filter setting is too high.
Why is my Woodward APECS DPG-2101-001 Controller engine unable to carry rated load?
If your engine is unable to carry the rated load, the PID values may be too high, causing the controller to overreact and make large, rapid changes in PWM duty cycle output to the actuator. Improve PID tuning. Also, check the actuator linkage for fuel restrictions.
Why does my Woodward Controller engine overspeed at startup?
If your engine overspeeds at startup with the Woodward Controller, increase the Proportional value, increase the appropriate Gain value, or decrease the Startup Ramp Rate.
What causes engine instability with no load on a Woodward APECS DPG-2101-001?
Engine instability with no load on a Woodward Controller can occur if the fuel is restricted; check the actuator linkage. Another possible cause is low battery voltage.
What causes engine instability with load on a Woodward APECS DPG-2101-001 Controller?
Engine instability with load on a Woodward Controller can occur if the fuel is restricted; check the actuator linkage. Another possible cause is low battery voltage.
Why doesn't my Woodward APECS DPG-2101-001 engine reach set speed?
If your Woodward Controller engine doesn't reach the set speed, it could be due to several reasons: Integral being too low or zero PID values, which requires improved PID tuning. The Integral Low Limit setting may be too high; return the value to the default setting of zero. The Integral High Limit setting may be too low; return the value to the default setting of 99.
Why am I unable to modify parameters on my Woodward APECS DPG-2101-001 Controller?
You might be unable to modify parameters on your Woodward Controller if the parameter’s value is already at the maximum or minimum allowed value. Another reason could be a keypad failure, in which case the unit should be replaced. Also, check if Universal PST is communicating with the controller.
