MDM
Manual start unit

• Simple and basic unit
• 50/60 Hz compatibility
• Basic engine protection
• Preheat or “Energize to stop” output

The MDM unit from CRE Tech-

nology is a basic, microprocessor controlled unit designed to
start and stop the genset manually using the key switch and
pushbuttons on the front panel.
It has high power relay outputs
enabling it to interface directly
with diesel gensets.
When the engine is running,
the unit monitors fault conditions and shuts-down the engine automatically if an alarm
occurs. The alarms are indicated with LEDs which display the
first one to occur.

A SIMPLE PRODUCT FOR BASIC APPLICATIONS

The manual start and stop sequences have been reduced to their simplest
form. The front panel provides “RUN” and “OFF” positions, with a preheat button when required. This button is also used in the “energize to stop” mode.
The alarm LEDs show any engine fault conditions: overspeed, underspeed,
high engine temperature, low oil pressure, auxiliary shutdown.

ENERGIZE TO STOP CONTROL

The MDM is also able to control ‘Energize to Stop’ engines. When the ‘Energize
to Stop’ option is selected, the auxiliary relay output will be energized during
the stop timer and the led associated with this condition will be turned on.
The choice of engine type is made using a jumper switch.

50/60 HZ COMPATIBILITY

The limits for the correct generator frequency are 25 to 57 Hz when in 50Hz
operation and 25 to 68Hz for 60Hz operation.

RELIABLE AND SIMPLE

The MDM is dedicated for basic applications which require no extra costs or
expensive hardware. The MDM has passed EMC and low voltage tests, and all
units are 100% tested before delivery.
