CONTROL MODULE OVERVIEW

The ES53 Control Module is a combined "engine controller + time delay module." It is typically

mounted at the engine, to minimize runs of heavy current carrying wiring. With #22 ga. wire,

distance between engine and transfer switch can be up to 400 feet. Standard cable length

supplied with the package is 50', and other lengths are available in 25' increments. The cable has

the connector terminals pre-mounted on one end, but the engine end must be field installed.

BRIEF SUMMARY OF OPERATION: The ES53 will start the generator engine on loss of

Utility power. It incorporates a TDES, during which time the glow plugs are energized, if

present. Cranking is then initiated for the selected time, OR until the engine starts. After starting,

the engine is monitored for Low Oil pressure, High Coolant temperature, and engine over-speed;

if any of these conditions are seen, the engine is stopped. The Low Oil Pressure circuit is

bypassed for a 15 second period after start-up to allow oil pressure to build-up. On completion

of the TDNE period AND provided the generator frequency has reached at least 55Hz (45Hz for

a 50Hz system), the transfer switch operator is actuated, and the load is switched over to the

generator power source. On return of the normal source, the controller waits for the preset TDEN

time to elapse, and then enables the transfer switch actuator to return the system load to the

Utility. After running unloaded for the duration of the TDEC period, the engine is then shut

down.

The ES53 uses the output of the generator as a speed signal; no magnetic pick-up is necessary.

This greatly simplifies hook-up to a small generator system and provides AC frequency sensing

on the generator source.

Loss of Speed While Cranking: Loss of speed detection is disabled during cranking on the ES53

unit due to very low residual voltages present during cranking when using direct generator

coupling. However, Loss of Speed during running shutdown feature is provided.

AC Frequency Sensing: The AC frequency of the generator is monitored to ensure that it falls

within specified limited. The frequency of the generator must be at least 55Hz (45Hz for a 50Hz

system) in order to permit transfer to the emergency source.
