When an output is configured for the SCADA data link, its active state can be sent over the Modbus.
5.3 analogue Input Programming
PowerWizard 2.1 and 1.1+ have three analogue input channels and PowerWizard 1.1 has two. For a Mechanical Unit Injector
Engine (MUI), two of the inputs are dedicated to monitor the engine coolant temperature and the engine oil pressure. The
Analogue Input #3 has a default configuration to "disabled".
All three analogue inputs can be programmed to monitor any supported parameter in Table 8 for an Electronic Unit Injector
Engine (EUI). In this case the engine oil pressure sensor and the engine coolant temperature sensor are wired to the Engine ECM
and not to the PowerWizard.

Analogue inputs can be configured from menu options:
MAIN MENU > CONFIGURE > INPUTS & OUTPUTS > ANALOGUE INPUTS
There are three USAGE TYPES for an available input: DISABLED, RESISTIVE and VOLTAGE SENDER. Each of the inputs can be
configured to have HIGH WARNING, LOW WARNING, HIGH SHUTDOWN or LOW SHUTDOWN with thresholds. Each event
associated with the input also has a programmable time delay.
1. resistive sender
DATA IDENTIFICATION for a resistive sender can be selected from the list in Table 8, e.g. temperature, pressure or level. The MAP
SELECTION NUMBER is used to select a map in connection with the sender. PowerWizard has up to 25 maps available for resistive
senders as shown in Table 9. Each map is defined in factory and contains up to 25 interpolation points.
