Execution

Are devices of other manufacturers used, the following pressure switching
values are checked on location. The operator must ensure that the
pressure switching values are checked on location.
Description
DIFF A / DIFF B
(flow rate on pressure control device)
Min A / MIN B
(minimum internal housing pressure, deactivation-
value)
MIN P (freely selectable preliminary alarm)
DP 1 (minimum or command operating pressure)
MAX (maximum internal housing pressure)
MAX 1 (maximum purging pressure)

1. Keep the documentation of all applied products ready.
2. Check the products for damage.
3. Check all mechanical and electrical connections (incl. the grounding
conductor!).
4. Activate the safety and monitoring equipment of the system.
When all prerequisites have been fulfilled, proceed as follows:
1. Activate the fan for the MAD motor or the external coolant system to
cool the MAF motor.
2. Check the values shown on the designation label on the motor (see
Fig. 5-3), such as the purging volume, the scavenging gas, the
purging time, etc. These values must be set, attained and maintained.
Heed the details of the manufacturer of the control device.
3. Activate the control device of the motor purging.
4. Carry out the commissioning of the drive system according to the
instructions of the corresponding product documentation. You can
find the respective information in the functional description of the
drive-devices.
5. Log all measures taken in the commissioning log.
Commissioning of drive controllers and the control unit may require
additional steps. The inspection of the functioning and performance of the
systems is not discussed in these operating instructions; instead, it is
carried out within the framework of the commissioning of the machine as
a whole. Observe the information and regulations of the machine
manufacturer.
