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.
