SIL790 Series Offers
Agriculture A NEW Generation of Diesel Irrigator Pump Control &
Instrumentation
During November and December SIL delivered 790 Series
controllers to 2 major new clients with a third to receive panels in
January 07.
Simplified Starting - no manual overrides - no switches to
enable protection
Monothrottletm - uses one Swichgage for throttle
and shutdown protection
First Out Fault Indication - Individual messages indicating separately
all cause of shutdown
Warm Up and Cooldown - the 790 series includes automatic warm
up and cooldown as standard. Modern high power engines benefit from
warm up and cooldown periods before and after operation at high
load.
High Quality Enclosure - Single and double door versions
available
Customisable - Customers design their own ideal combination
of instruments and controls.
Cost - the 790 series can offer significant cost savings
compared with traditional panels.
Proven - the 790 series has been put
into limited service during 2006 with selected customers for
reliability verification. All trial demonstrated very high reliability
and high level of operator satisfaction.
The Main new feature benefiting users is the unique Monothrottle
(TM) system. Traditional arrangements for throttling need 2 water
pressure Swichgages. One used for High/Low Pressure fault shutdown.
The second used for throttle adjustment for maintaining pump
discharge pressure.
Monothrottle (TM) uses a single Swichgage for both functions. The
monitors high and low pressure signals and automatically determines
abnormal conditions and initiates shutdown protection. When no
abnormal conditions are detected then the high/low pressure signals
are used to adjust engine speed.
The 790 series include automatic warm up
and cooldown as standard. modern high power engines benefit from
warm up and cooldown periods before and after operation at high
load.
Mechanical timers are eliminated helping
avoid failures, and protection override and maximum run time delays
are set automatically.
