3. As the unit starts release the Start Switch and it will return to
the run position. You must continue to depress the Safety Latch
Relay button until the Check Engine light goes out. When this
light goes out, it indicates that the engine has built sufficient oil
pressure to operate properly and the high coolant temperature
has not been exceeded.

***** WARNING *****
*************
EQUIPMENT DAMAGE
- DO NOT DEPRESS THE SAFETY
LATCHING RELAY BUTTON FOR OVER 10 SECONDS. IF THE
LIGHT HAS NOT GONE OUT IN 10 SECONDS IT INDICATES
THAT EITHER THE ENGINE HAS NOT BUILT OIL PRESSURE
OR THE COOLANT TEMPERATURE HAS EXCEEDED THE
ALLOWABLE MAXIMUM.
4. After the engine is up an running the circuit breaker can be
closed to power your loads. During periods of very cold operation
it is best to let the engine warm up for a few seconds before
applying the load.
5. When stopping the unit it is best to turn off all the loads before
turning the Start Switch to the off position. This prevents your
loads from getting low voltage while still running during unit
shutdown.
If for some reason during operation the oil pressure should drop
below the allowable oil pressure or the water temperature should
exceed allowable level the Safety Latching Relay button will pop-
out and the unit will shutdown. You will also get a check engine
light at this time.
If you find the unit stopped with the relay button popped-out, it
could have been caused by either low oil pressure or high water
temperature.
DSE 3110 ELECTRONIC
START CONTROL
A. Deep Sea 3110 Engine Control -
See controller explanation
on the following page.
B. 2 AMP FUSE -
This fuse is in the AC input line from the
generator. This feed that provides the AC voltage reading on
the display. If this fuse is blown the DSE 3110 will not display a
voltage or frequency reading and will shutdown on low voltage or
frequency. (Replacement fuse ATO-ATC 2A-250 Volt)
C. 2 AMP FUSE -
This fuse supplies the 12 volt DC to power the
DSE 3110 controller circuity on the boards. If this fuse is blown
the DSE 3110 will not function at all. (Replacement fuse ATO-ATC
2A-250 Volt)
D. 10 AMP FUSE -
This fuse supplies the 12 volt DC to power
the two pilot relays in the control panel (one relay operates the
fuel system and the other operates the starting system). If this
fuse is blown the DSE 3110 will show the unit has gone in a start
mode but nothing will happen out on the engine generator set.
(Replacement fuse ATO-ATC 10A-250 Volt).
E. START SYSTEM PILOT RELAY-
This is the pilot relay drives
the starter solenoid on the engine starter. When the DSE 3110
calls for the unit to start, this relay is closes sending a 12V
positive signal (lead #22) to the control terminal on the start
solenoid mounted on top the starter on the engine. This relay will
open when the DSE 3110 senses voltage and frequency on AC
feedback circuit from the generator disconnecting the starter.
F. FUEL SYSTEM PILOT RELAY-
This is the pilot relay for the
both the fuel solenoid and the 12V field signal for the alternator
on the engine starter. When the DSE 3110 calls for the unit to
run this relay closes and sends a 12V positive (lead #21) to both
the fuel solenoid and the field circuit on the engine alternator.
This relay will stay closed as long as the DSE 3110 is in the run
position or until a safety shutdown is activated, at which time the
relay will open. When the relay opens all power to lead #21 is
disconnected and the engine will shut down. Also if the engine
has shutdown one of the safety shutdown a fault code will be
displayed. These codes will be discussed later.
