Deep Sea 7420
The “7420” controller is an
auto start mains (utility)
failure module for single
gen-set applications. This
controller includes a backlit
LCD display which
continuously displays the
status of the engine and
generator at all times.
The “7420” controller will also monitor speed, frequency,
voltage, current, oil pressure, coolant temp., and fuel levels.
These modules have been designed to display warning and shut
down status. It also includes: (11) configurable inputs • (8)
configurable outputs • voltage monitoring • mains (utility)
failure detection

Level 3, Hospital Silencer ........................................ ........... 75
Note: Open sets (no enclosure) has (2) optional silencer system choices
due to unknown job-site applications. Level 2 enclosure has installed
critical silencer with upgrade to hospital silencer. Sound tests are
averaged from several test points and taken at 23 ft. (7 m) from source
of noise at normal operation.

APPLICATION AND ENGINEERING DATA FOR MODEL SP-3500-60 HZ
DEEP SEA 7420 DIGITAL MICROPROCESSOR CONTROLLER
LOW LOAD CONDITIONS: Operation of PSI HD engines at low-load conditions should be limited to no more than one (1) hour per twenty-four (24) hour
period. If the application requires extended time at light loads, it is recommended that the engine load be increased to at least 70% of mechanical rating for a
minimum of two (2) hours per fifty (50) hours of low-load operation. Piston sealing rings rely on adequate cylinder firing pressure and temperature to seal the
combustion chamber and prevent excessive engine oil from entering the power cylinder. Under low loads these rings will not seal properly, resulting in oil being
burned in the combustion chamber and carbon deposits on pistons and valves. This mechanism is well-documented in reciprocating engines of all fuel types
and is often referred to as “wet-stacking.”
