5.6. Coolant and Fuel
The coolant heater must not be operated while the
cooling system is empty or when the engine is running
or damage to the heater will occur.
Coolant under pressure have a higher boiling point
than water.
• Do not open a radiator, heat exchanger or header
tank pressure cap while the engine is running. Allow
the generator set to cool and bleed the system pres
-
sure first.
• Never use galvanised or copper fuel lines, fittings or
fuel tanks. Condensation in the thanks and lines com
-
bines with the sulphur in the fuel to produce sulphuric
acid. The molecular structure of the copper or galvan
-
ised lines or thanks reacts with the acid and contami-
nates the fuel.
6. GENERATING SET CONTROL SYSTEMS
To control and monitor the generator set, an elec
-
tronic control system has been used. Control panel
provides a means of starting and stopping the generat
-
ing set, monitoring its operation and output and auto-
matically shutting down the set in the event of critical
condition arising such as low oil pressure or high en
-
gine temperature.
6.1. Control System P 732
P732 control system is fitted to 220kVA and above
generator sets. It is designed to start and stop for all
electronic or non–electronic diesel engines Generator
Sets automatically , besides control module monitor
the mains voltage , frequency and controls the gen
-
erator set and transfer system. Control, monitor and
protection panels are mounted on the generator base
frame.
“DSE P732 AMF Control Module Operating Manual”
is given along with the Gensets.
