How to troubleshoot Woodward Controller speed input not working?
- B
  Brooke BrownAug 12, 2025
  If the speed input on your Woodward Controller isn't working, check the wiring and terminal block connections first. Next, use the front panel to access the Speed Input Configure Menu and ensure all configuration options are correctly selected. Make sure there aren't any alarms or faults that could indicate a setup problem, such as an open wire trip, speed lost, or speed fail. Confirm that the input signal levels meet the electrical specifications, and check the shield connections. If you're using an active probe, disconnect it and measure the voltage from terminals 69 to 71; it should be 24 V ±10%. Reattach the probe and measure again to confirm that it isn't overloading the voltage provided by the ProTech-GII.

How to troubleshoot Woodward Controller programming and configuration tool not working?
- C
  Christopher CoxAug 16, 2025
  If the Programming and Configuration Tool is not working with your Woodward Controller, verify that the cable plugged into the DB9 port is a straight-through cable, not a crossover cable. Ensure that power is applied to the ProTech-GII module to which the Programming and Configuration Tool is connected. Confirm that the correct COM port is selected when establishing communications and that Auto Detection BAUD rate is selected.

What to do if Woodward Controller power supply input is not working properly?
- L
  laraadrianAug 19, 2025
  If the Woodward Controller's power supply inputs aren't working and a power supply input alarm is present, start by checking the wiring and terminal block connections to ensure they are secure. Verify that the power source breaker or fuse is not open. Confirm that you have connected at least two power supplies. Check the input voltage level to ensure it's within the acceptable range according to the electrical specifications. Also, verify that the power supply has the appropriate rating to power the ProTech-GII. You can check for Power Supply 1 or 2 Fault by pressing the VIEW button under the ALARM LED on the front panel.

What to do if Woodward Controller trip relays are not working?
- A
  Alexis HarrisAug 23, 2025
  If the trip relays on your Woodward Controller are not working, start by verifying the wiring and terminal block connections. Then, use the Programming and Configuration Tool or the front panel to check that the trip configuration is set correctly, considering whether 'energize to trip' or 'de-energize to trip' is selected, as this affects relay polarity. Check the power supplies providing voltage to the relay output. If you're using the 24 V EXT from the ProTech-GII, measure the voltage between terminals 80 and 81 to ensure it's 24 V ±10%. If it's not, disconnect the wiring from the 24 V EXT to reduce the load and measure again to see if the voltage is being overloaded.

Why is dedicated discrete input not working on Woodward Controller?
- E
  ericarothAug 27, 2025
  If a dedicated discrete input (Start, Reset, or Speed Fail Override) on your Woodward Controller isn't working, first check the wiring and terminal block connections. Then, use the front panel to access the Dedicated Discrete Inputs Monitor Menu and verify that the logic state is correct. Check the signal level to ensure it's within the acceptable range according to the electrical specifications. Measure the voltage from terminal 1 to terminal 81; it should be 23 V ±2 V. If the voltage is out of range, return the unit to Woodward.

How to fix MODBUS on Woodward Controller?
- R
  Raymond HernandezAug 31, 2025
  If MODBUS is not working on your Woodward Controller, begin by checking the wiring and terminal block connections. Specifically, ensure that the HI and LO wires are terminated to the correct terminals for RS-485, and the TXD and RXD wires are correctly connected for RS-232. Also, verify that the termination jumpers are installed for RS-485 mode. Using the PCT or front panel, verify that the correct settings are selected.

What to do if alarm relay output is not working on Woodward Controller?
- J
  Jeremy SanchezSep 3, 2025
  If the alarm relay output on your Woodward Controller is not working, start by verifying the wiring and terminal block connections. Check the power supplies that provide voltage to the relay output. If you are using the 24 V EXT available from the ProTech-GII, measure the voltage between terminals 80 and 81 and verify it is 24 V ±10%. If it is not, remove the wiring from the 24 V EXT to unload the output and measure again to verify the voltage is not being overloaded.

Why is analog output not working on Woodward Controller?
- T
  Troy WilliamsSep 7, 2025
  If the analog output on your Woodward Controller isn't working, first check the wiring and terminal block connections. Then, use the front panel to access the Monitor Analog Output Menu and verify that the analog output is reading an expected output value. Measure the current from terminal 64 to confirm it corresponds to the previous step. Ensure the load on the analog output is within the electrical specifications. Finally, use the PCT or front panel to verify that the scaling is correct.
