ENGINE AR-PRIMARY 5425532 - Caterpillar

will FLASH and the AL5 fault code is immediately shown on the upper display.When the fault is programmed as an alarm fault, the fault alarm indicator will FLASH and the "AL5" fault code is shown on the upper display after the "Alarm Codes" key is pressed.AL6 High Engine Oil Temperature Fault - When the engine oil temperature rises to within 6 °C (11 °F) setpoint P026, the GSC+ issues a high engine oil temperature fault. The GSC+ can be programmed (P027) to treat this fault as an alarm, a shutdown, or the fault can be disabled (P025). When this fault occurs, the GSC+ can be programmed to light one of the spare fault indicators that is located on the GSC+. The programmable setpoints are SP17, SP18 and SP19.When the fault is programmed as a shutdown fault, the fault shutdown indicator will FLASH and the "AL6" fault code is immediately shown on the upper display.When the fault is programmed as an alarm fault, the fault alarm indicator will FLASH and the "AL6" fault is shown on the upper display after the "Alarm Codes" key is pressed.AL7 Generator Over Voltage Fault (protective relaying function) - When the line to line voltage between any two phases of the generator rises above the P102 setpoint or the P105 setpoint, the GSC+ issues an overvoltage fault. The GSC+ can be programmed to enable or disable this fault as an alarm, a shutdown, or an alarm and a shutdown. The setpoints for the overvoltage fault are P101 and P104. The fault can be programmed with a time delay from 0 to 120 seconds. These setpoints are P103 and P106. The fault threshold can be adjusted from 100 percent to 125 percent of the nameplate voltage for the generator (P028. The setpoints for the fault threshold are P102 and P105.When the fault is enabled as both an alarm fault and a shutdown fault, the fault thresholds and time delays can be programmed independently to allow the alarm fault to serve as an early warning for the shutdown fault.When the fault is programmed as a shutdown fault, the fault shutdown indicator will FLASH and the AL7 fault code is immediately shown on the upper display.When the fault is programmed as an alarm fault, the fault alarm indicator will FLASH and the AL7 fault code is shown on the upper display after the "Alarm Codes" key is pressed.Note: If the AC offset adjustment OP10 has been performed, then the adjusted voltages are NOT used for determining the fault thresholds for protective relaying functions. The values that have not been adjusted for AC voltage are still determined by the GSC+ (but not shown), and the values will be used instead of the displayed values.AL8 Generator Under Voltage Fault (protective relaying function) - When the line to line voltage that is between any two phases of the generator drops below Setpoint P108 or Setpoint P111, the GSC+ issues an under voltage fault. The GSC+ can be programmed to enable
