Speed Inputs
The speed sensors are connected to the LEMO connectors S1 for the first speed sensor and
S2 for the second speed sensor. The supply voltage for the speed sensors is directly supplied
by the PeakStore5.
The optical speed sensor is used to measure the speed on rotating machine parts. Before
installation and positioning a reflex tape must be placed on a rotating machine part. The optical
speed sensor must be oriented and fixed towards the reflex tape. The distance between reflex
tape and sensor should be between 25 and 80 cm. The optimal orientation is signalized by a
blinking LED on the sensor if the PeakStore5 is switched on. The correct speed measurement
can be verified in the sensor overview of the PeakStore5 or via the remote control. The display
can variate slightly. If there are heavy variations, the orientation of the speed sensor should be
checked and the measurement should be repeated.

External sensor supply voltage and protected earth connection
If the connected sensors require an additional supply voltage (Pin 2 and 3 in 4.1), the DC IN
connector on the right side of the PeakStore5 can be used to connect an accumulator with the
desired voltage. If the connected supply voltage is greater than 14 V, the connected speed
sensors are also powered by the external supply to reduce the load from the internal accumu-
lator.
Note:
Only a supply voltage of 24 V DC or lower must be connected to the DC IN connector.
Furthermore, the DC IN connector can be used to connect the PeakStore5 with protected earth
with an optional available protected earth cable.
