Description:
In normal mode, EMD measures condensed water level in its tank. When level reaches

threshold, the valve is opened and water is discharged. Period between successive
discharges is from 5s to 7s long. When there is so much water, that EMD is not able to
remove it in 90s, it enters overload mode. In this mode, EMD opens its valve longer and

more frequently and its capacity is doubled. When EMD is still not able to discharge all the
water in 5min, it enters alarm mode. In alarm mode, EMD opens its valve so that it would
discharge 50% of its nominal capacity. The capacity in alarm mode is limited to limit air

losses in case of drain malfunction. EMD returns from overload or alarm mode to normal
mode when the tank gets empty.
Extreme amount of condensed water is possible after maintenance work. In front of EMD,
there is valve that is closed during maintenance. Behind this valve, condensed water collects.
After a while, there is so much water that EMD is not able to drain it without entering alarm
mode. To avoid entering alarm mode, test button should be pressed after each maintenance
work to discharge all condensed water manually.
