Report from MPR site (29 Dec 2011)

Basically the MPR has been working well without problems except the
following two.

On 27th:

At around 1015 LT, we found that the coolant level of the generator was
zero. At 1020 LT, we stopped the generator and plugged the PLN cable.
Then we restarted the radar operation. After that we checked the
condition around the generator. As a result we found a coolant leak from
the hose between the coolant tank and the generator. We repaired it and
poured water into the coolant tank. At 1214 LT, we unplugged the PLN
cable and restarted the generator. Then we restarted the radar operation.

On 29th:

At 0634 LT, suddenly the generator stopped. At 0637 LT, we found that
the display on the control panel for the generator showed the message
"FAULT! OILPRESSURE DOWN". At 0638 LT, we plugged the PLN cable and
restarted the radar operation. At around 1130 LT, we found a oil leak in
the box of the generator.
