INTRODUCTION | PAGE 4
The measurements module has outputs which allow the status of the control unit
to be monitored:
• Motor started.
• Control unit alarm.
• 3 programmable outputs that monitor the status of the control unit
alarms or the engine status inputs.
The measurements module commands relay outputs for activation of the genset
contactor and the electronic protection that trips the genset's general circuit
breaker.
The connection of the measurements module and display module is performed
via a CAN communications bus, enabling the interconnection between additional
modules which ensures the scalability of the control unit.
The following additional modules can be added as options via the CAN bus:
• Telesignal device.
• CCJ1939 device.
• Repetitive display.
• Telecontrol device.
• Announcement panel device.
• C2CLOUD (GPRS and eet manager).
• CAN/485 (MODBus).
• CAN2LAN.
• CAN2LAN (MODBUS IP).
• CAN2LAN HG FLEET MANAGER.
• CAN2LAN (SNMP).
• Second Zero Suppressor.
• PT100 temperature probes expansion.
• ATS panel with CEC7 control unit.
• Precision gauge.
• CAN/USB.
The measurements module provides the following engine characteristics:
1. Engine alarm inputs:
• Fuel reserve.
• Oil pressure.
• Water temperature.
• Water level.
• Emergency stop (mushroom head stop button).
2. Analogue inputs of the engine:
• Fuel level.
• Pressure.
• Temperature.
• Congurable input (Oil temperature).
• Charge-battery alternator voltage.
3. Congurable inputs; the measurements plate has 5 inputs that can be
programmed to perform the following functions:
• Tariff change warning.
• Tariff change (CEM7 + CEC7).
• Start up disabling.
• External start.
• Test (CEM7 + CEC7).
• Forced operation.
• Programmable alarms.
• Genset contactor conrmation.
• Parameter set selection.
4. Engine statistics:
• Operating hours.
• Number of starts.
5. The measurements module commands the following engine functions:
• Preheating.
• Stopping.
• Starting.
• Heating resistor.
• Fuel transfer pump.
• Battery charging alternator excitation.
