What to do if Deif SGC 120 Controller generates unnecessary Shutdown alarms or Warning alarms?
If the Deif Controller generates unnecessary Shutdown or Warning alarms, check the corresponding switch, sensor, and wiring. Also, verify the respective threshold configuration in the Controller's Configuration mode.
What to do if Deif SGC 120 Controller shows Charge Fail alarm?
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.
Why Deif SGC 120 shows Emergency Stop alarm when it is not activated?
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 Error C03?
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 does not maintain the target RPM?
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.
How to troubleshoot Deif Controller when it does not start the engine with remote command?
If the Deif Controller doesn't start the engine when a Remote start command is sent, check the wiring of the Remote start signal to the controller's digital input terminal. Also, verify the configuration for the Remote start digital input terminal in the Controller's Configuration mode. Ensure that the controller is in Auto mode and that Mains monitoring and Site mode are disabled.
What to do if Deif SGC 120 Controller does not stop engine with remote command?
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 Controller sends a Crank-start command immediately after power on?
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.
How to troubleshoot Deif SGC 120 when it does not power on?
If the Deif Controller is not powering on, check the battery voltage, the fuse on the battery supply, the continuity between the battery positive and controller terminal 2, and the continuity between the battery ground and controller terminal 1.
Why Deif Controller shows genset to be OFF when engine runs?
If the engine runs, but the Deif Controller shows the genset to be OFF, check if the MPU signal (if used) and the main alternator voltage signal (L1 phase) are received by the controller terminals. Also, check if the LOP and LLOP are working correctly and verify the wiring to the controller.
