Instrument cluster PP7.1

Features exceptional reliability drive of meters high accuracy LED backlight of gauges and meter needles LED control lamps hour meter

The PP7.1 is a seven function, microprocessor based instrument that can be factory defined to monitor various functions, including pressure, temperature, fuel, voltage, speed, engine angular velocity and hour meter.

The instrument cluster provides accurate measurement and display:

• engine oil pressure — to 10 kPa;
• transmission oil temperature  — from 20 to 120 °�;
• engine coolant temperature — from 20 to 120 °�;
• fuel tank level;
• engine angular velocity (tachometer) — to 3000 rpm;
• voltage indicator — from 20 to 32 V DC;
• hour meter — to 99999 hour.

The dashboard has control lamps of necessary color:

• low engine oil pressure;
• high engine coolant temperature;
• fuel heating;
• low fuel level;
• low torque converter input oil pressure;
• low torque converter output oil pressure;
• low transmission oil pressure;
• hydraulics oil cleaner clogging;
• engine air cleaner clogging;
• engine oil cleaner clogging;
• low turbocompressor oil pressure;
• gear-shift mechanism neutral position;
• engine heating system.

Application-specific adaptations can be created on request.
