at all and hereby save fuel. If the engine has been running for a long period it will have reached
normal running temperature, the cool-down period will be the exact time it takes to lower the
temperature to be less than the temperature in set point 6213.
If, for some reason, the engine cannot lower the temperature below the temperature set point in
6230 within the time limit in parameter 6560, the engine will be shut down due to this timer. The
reason for this could be high ambient temperature.
The temperature-controlled cool-down function is selected in parameter 6214.

Test function

The MEC 310 has two test sequences if the option A is enabled. The test sequences can be
initiated in two ways: Either with the test push-button on the front of the MEC 310 or by a digital
input configured to this function.
Simple test function
When the simple test is initiated, the MEC 310 will go through the start sequence and run the
engine for the time set in parameter 7090. In this parameter it is also selected if this sequence
should be started by a digital input and/or the test push-button on the front of the MEC 310. If the
timer is set to 0, the test sequence will be interrupted when the digital input or test push-button is
deactivated. This means that digital input can be used to activate and deactivate the test sequence.
When the timer runs out or the input is deactivated (timer set to 0), the stop sequence including
cooling down will be carried out.
The MEC 310 must be in Auto mode in order to initiate the test sequence.
