CM170407AMA
MPS49. An internal rechargeable totally sealed battery is housed within the instrument and
is easily removable from the front panel.
1.5 MAINTENANCE AND REPAIR
The MPS49 is to be maintained and repaired using the approved procedures and be
carried out only by DMA authorized agencies or the manufacturer.
1.6 INFORMATION AND ADVICE
Contact the manufacturer, subsidiary or agent for further detailed technical advice.
1.7 NOTE
This Manual is applicable starting from SW Version 1.12.
1.8 IMPORTANT NOTES
•
The manual vent valves on the front panel must be closed before the start of testing.
•
Connect the ADTS to the static, pitot and AoA ports only after the start up procedure is
completed.
•
For optimum operation and highest precision, the MPS49 should be operated with the
front panel face up.
•
When transporting the MPS49 in an unpressurized aircraft, use the VENT/SEAL valve
(if available on the case) to prevent damage, to keep the pressure inside and outside of
the case equal.
•
It is recommended to mount the MPS49 at a height of 1 meter above floor level where
fuel vapor could be present, for example during re-fueling operations.
•
The total volume of the pneumatic circuit of the MPS49 is small. When no pneumatic
load is connected to the ADTS, thermal effects could result in apparent leaks. The final
inspection and calibration procedures indicate rate values and stabilization times that
must be followed in order to compensate for thermal effects.
1.9 GETTING STARTED
Prior to using the MPS49 the following points should be considered.
1.9.1 INTERNAL BATTERY
The internal battery can be removed from the front panel. It is not strictly required for
operating the MPS49. However it also serves as an emergency back up system, to safely
return the instrument and aircraft system to ground conditions in the event of an external
power failure during testing.
1.9.2 BATTERY CHARGING
The internal Battery has an operational life of 2 hours when fully charged. On receipt of the
MPS49 the internal battery will require charging. Due to internal monitoring circuits, the
battery will slowly discharge when not in use. The battery is recharged whenever the
MPS49 is connected to an AC power supply.
The time needed to fully recharge the battery when connected to the AC supply is 2 to 3
hours.
