Constant Speed (No Sensor)

Main Speed Sensor

Shields are common, but not grounded to chassis. Run cable shields through
Note:
SHLD terminals and ground at BW500 and BW500/L only.
Connect BW500 and BW500/L terminal 16 to speed sensor terminal:
• '2' for clockwise speed sensor shaft rotation
• '3' for counter-clockwise speed sensor shaft rotation.
Speed sensor shaft rotation is viewed from the front cover of the speed sensor
enclosure.
Input device in the form of open collector transistor or dry contact across BW500 and
BW500/L terminals 16 / 17 will also serve as a suitable speed signal.
If a speed sensor other than the models shown is supplied, consult with Siemens for
details.
A second speed sensor input can be added using the Auxiliary inputs: the second speed
input allows calculation of Differential Speed. For more information, see
(P270)
on page 122.

If a speed sensor is not used, a jumper or contact
closure must be connected across BW500 and
BW500/L terminals 17 / 18 when the conveyor is
running. If a speed sensor is used, ensure that the
jumper is removed.
With contact closed or jumpered
Note:
when the conveyor is idle, the integrator will
continue totalizing
