Moisture Compensation - Siemens Milltronics BW500 Operating Lnstructions

generally reserved for the driving device (head pulley), and is used for comparison to the
primary speed sensor, for differential speed detection only.
The second speed signal is compared to the primary speed signal, and will initiate an
alarm condition if the second speed signal is outside the programmed high and low alarm
setpoints.
Connect the second speed sensor as shown in the Installation section (refer to
Speed Sensor
on page 21), and program the second speed sensor as described in the
following steps:
1. Program one of the Auxiliary Inputs as a Speed Sensor input P270-01 to 05 = 16
(Speed Sensor).
2. Program second speed sensors speed constant P015-02 = pulses per meter or foot

3. Program one of the alarms for Differential Speed Detection alarm P100-01 to 05 = 10
(Speed Differential).
4. Program the High Alarm setpoint P101-01 to 05 = 110% (default).
5. Program the Low Alarm setpoint P102-01 to 05 = 90% (default).

Moisture Compensation

Moisture Compensation is used to compensate for the moisture component of the
material being weighed. It factors out the moisture component of load, rate and total for
all multispans selected. The factored value is meant to report the dry mean values of the
material being conveyed.
The BW500 receives the static load cell signal, and adjusts the value of the load being
displayed and integrated by the moisture percentage. The mA I/O card is required to
accept the mA signal from the Moisture Meter. This mA signal can represent 0 to 100%
moisture. The moisture percentage is displayed in P398-01. Using P398-02, the moisture
percentage can be represented as a percentage of mass to be deducted from the total
