Why Deif SGC 120 Controller sends a Crank-start command immediately after power on?
- R
  Rachael BellSep 2, 2025
  If the Deif Controller sends a Crank-start command immediately after power on, ensure that the controller's output terminal is not directly connected to the starter relay. The controller's output should be given to an intermediate relay which should in-turn power the starter relay. The controller can get permanently damaged and will need to be replaced if this precaution is not taken. Check start-relay connection with the suitable controller terminal. Verify the configuration for Start mode and the Start relay output polarity in the Controller's Configuration mode.

  If the Deif Controller doesn't stop the engine even when a Remote stop command is sent, check the wiring of the Remote stop signal to the controller's digital input terminal. Also, verify the configuration for the Remote stop digital input terminal in the Controller's Configuration mode. Ensure that the controller is in Auto mode.

Why Deif SGC 120 does not maintain the target RPM?
- B
  Brandon FryAug 27, 2025
  If your Deif Controller isn't maintaining the target RPM, the engine RPM is unstable, or it cranks but doesn't start, try the following: * Make sure the mechanical linkage is working correctly. * Check the GOVERNOR configuration in the Controller's Configuration mode. * Verify the PID control gains. * Ensure the actuator moves to full throttle when cranking the engine.

What to do if Deif SGC 120 Controller shows Error C03?
- C
  Cynthia JamesAug 27, 2025
  If the Deif Controller displays Error C03, which can happen if it loses connection to the PC during configuration, try these steps: First, press and hold the Stop/Config button while you restart the power to reset the controller. Then, resend the configuration file.

Why Deif SGC 120 shows Emergency Stop alarm when it is not activated?
- A
  Alexander JohnsonAug 25, 2025
  If the Emergency Stop alarm appears on your Deif Controller when the Emergency Stop isn't activated, check the emergency stop switch and its wiring to ensure they are working correctly. Also, verify the Emergency stop polarity configuration in the Controller's Configuration mode.

What to do if Deif SGC 120 Controller shows Charge Fail alarm?
- C
  Christopher MillerAug 22, 2025
  If the Deif Controller shows a Charge Fail alarm, follow these steps: * To check if the controller's charging alternator terminal is working: Disconnect the charging alternator wiring to the controller's terminal 7, short terminal 7 to the ground through a DC ammeter, crank-start the engine. The DC ammeter should indicate the current in the range of 200 to 400 mA for ~30 seconds. If yes, the controller's charging alternator terminal is working OK. * Disconnect and reconnect the charging alternator connection to the controller's terminal 7. * Check if the charging alternator is working OK.
