Action Code Display As previously discussed, if a fault occurs in any of the monitored systems, a code will be displayed on the "MOM" screen. At the same time an action code will also be displayed to inform the operator of a proce- dure to follow because of the fault. This "action code" is also displayed on the electronic display panel.
The electronic display panel will display the action code of any fault informed through the serial communications network, "S-NET," from any controller that detects a fault. When the fault occurs, the action code of this fault will be displayed automatically. 3. Next move the range selector to either DRIVE, 5th, 4th, 3rd, LOW or REVERSE.
