External trigger sources (e.g. patient monitoring system) may be
connected with the help of the trigger input to drive MR sequences.
The connection for the trigger input is located on the cover of the MR
system. Trigger input is galvanically isolated with respect to the MR
system.
Both the PERU and the PPU are supplied with power via accumulators.
All other components of the PMU are supplied by system-internal
voltage sources. The charging station is installed separately near the
syngo Acquisition Workplace and is used for storing both units.
Accumulators should not be fully discharged before recharging them.
If only one green LED flashes, you should charge the accumulator for
the next patient. The maximum charging time is approx. 3 hours.
After being fully charged, the operating hours for the units cover
approximately 24 hours.
To charge a unit, it has to be placed firmly in the charging station.
The PERU and PPU can be charged together or separately in the
charging station.

Use only the charger included with delivery. Charging the units
with non-Siemens equipment may destroy the PERU and PPU.
If proper charging of the accumulators is not possible anymore,
please contact Siemens Service, as the PMU accumulators cannot be
exchanged.
The red LED goes out when the unit is positioned correctly in the
charging station. While charging, the green LEDs flash alternately as
moving light. If the accumulator is nearly discharged, only one LED
flashes at the beginning. With increasing charging status, a second
green LED flashes and then also the third LED. If the accumulators are
fully charged, the 3 green LEDs are on and stop flashing.
