What does it mean when Deif SGC 420 shows Error C03?
Error C03 on the Deif Controller can occur if the controller is disconnected from the PC during a configuration. To resolve this: 1. Push and hold the Stop/Config button during a power cycle to reset the controller. 2. Re-send the configuration file.
Why does Deif SGC 420 show Emergency stop alarm when it is not activated?
If the Emergency stop alarm is shown on the Deif Controller without the Emergency stop being activated, check if the Emergency stop switch is working OK, including the wiring. Also, enter the Configuration mode in the controller and verify the configuration of the Emergency stop polarity.
What to do if Deif SGC 420 Controller shows Charging Alt Fail alarm?
If the Deif Controller displays a Charging Alt Fail alarm, here are some steps to investigate: * To check if the controller's charging alternator terminal is working: Disconnect the charging alternator wiring to the controller's terminal 10. Short the terminal 10 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 correctly. * Disconnect and re-connect the charging alternator ind connection to the controller's terminal 10. * Check if the charging alternator is working corrctly.
What to do if Deif SGC 420 Controller generates unnecessary shutdown alarms or warning alarms?
If the Deif Controller generates unnecessary shutdown or warning alarms, take these actions: * Check the respective switch, sensor and wiring. * Go to the Configuration menu. Make sure the threshold values for the alarms and warnings are configured correctly.
What to do if Deif Controller does not stop the engine when a remote stop command is sent from an external device?
If the Deif Controller does not stop the engine when a remote stop command is sent, check the following: * Check the wiring of the remote stop signal to the digital input on the controller. * Go to the Configuration menu on the controller. Make sure the digital input for the remote stop is configured correctly. * Make sure that the controller is in Auto mode.
Why the engine runs, but the Deif Controller shows genset to be OFF?
If the engine runs, but the Deif Controller shows genset to be OFF: * Check the alternator voltage signal (L1 phase) is received by the controller terminal. * Check if the LOP and LLOP are working correctly. Check the wiring to the controller.
What to check if Deif Controller is not sending data via Modbus?
If the Deif Controller is not sending data via the Modbus communication, check if the Modbus communication is enabled in the controller. Also, check if the Modbus communication settings of slave match with the master, if the connections are done properly for the Modbus input (terminals 31 and 32), if the connections are interchanged and the 120 ? resistance between terminal A (terminal 31) and terminal B (terminal 32).
Why does Deif SGC 420 Controller send a Start command even if the Mains is present?
If, while in Auto mode, the Deif Controller sends a Start command even if the Mains is present, check the wiring of the mains L1, L2, and L3 phase to the controller's respective input terminal. Also, enter the Configuration mode in the controller and verify the configuration for the Mains monitoring.
What should I do if the engine runs, but the Deif Controller shows genset to be OFF?
If the engine runs, but the Deif Controller shows the genset to be OFF, check if the alternator voltage signal (L1 phase) is received by the controller terminal. Also, check if the LOP and LLOP are working OK, and verify the wiring to the controller.
