BEARING-SLEEVE 9R7891 - Caterpillar

[ OPTIONAL USE ]
The discrete input/output (I/O) module is not required.General Information
The discrete input/output module is a device that can read 12 discrete inputs and operating eight relay outputs. The discrete input/output module can be mounted on the generator set package or mounted remotely in another location.Inputs
The discrete input/output module has 12 inputs with four return channels. The inputs can be activated by either switching to a return or by switching to battery negative. Each of the inputs can be configured to signal one of many possible events. The Caterpillar Service Tool is used in order to configure the discrete input/output module inputs.Inputs that generate a warning message will reset automatically whenever the input returns to a non-active state. Inputs that generate a shutdown message will continue until the input returns to a non-active state and a reset message is received by the module on the J1939 data link.The input configuration parameters are shown in Table 1.
Table 1
Configuration Parameters for Each Input    
Setpoint Parameter    Range    Default    
Input #inn Active State Configuration     Active Low
Active High     Active State Low    
Input #nn Time Delay     0 to 120 seconds     0    
Input #nn SPN     Any SPN (see Table 2 supported by EMCP 3     N/A    
Input #nn FMI     Any FMI supported by EMCP 3     N/A    Table 2 lists the "Suspect Parameter Numbers" (SPN) that the EMCP 3 supports for inputs and outputs. An SPN is an internationally recognized code that is assigned a specific meaning. For example, SPN 110 relates to the "Engine Coolant Temperature".
