Cosine Pendulum
Belt weighers with variable belt inclination are equipped
with a so-called cosine pendulum which compensates
the impact of inclination on measuring result.
The pendulum is switched into the load cell (L/C)
supply voltage.

RD = load cell input resistance in ohms
Rp = pendulum potentiometer resistance in ohms
Rw = calibrated resistance of Rv in ohms
1. Position pendulum near weighbridge and align
using spirit level.
2. Param.: Angle a (C 07) = 0
Lever (C 06) = table value
Basic Tare N (D 04) = 0
Tare Correction T (D 05) = 0
Do not tare scale.
3. Use Rv to preset RW with highest possible
accuracy.
4. Bring weigher into two opposite positions,
e.g. degr. Apply check weight, if necessary.
5. Set belt load displays to same value by correcting
the pendulum case zero point position.
6. Use potentiometer rv to vary range until until
minimum dependence of belt inclination is
reached.
If items 4 and 5 cannot be performed, use
pendulum position and Rv in turn.
7. Tare scale, best in horizontal position.
8. Calibrate range using check weight and
Parameter D 02. Use setting program CW.
Test Plug
Almost any possible error in operation is reported by
event message. For interpretation, see Chapter 10.
Check INTECONT for proper operation by using a
simple test plug. This helps to see whether the fault is
with load cel, or cabling and electrical equipment.
1. Switch plug as shown in drawing.
2. Withdraw load cell connector X7 and replace by
test plug.
At the indicated resistance values, the following
service values result:
1. wz apr.1.1mV/V
2. Load cell apr. 55 % (C 03 =2mV/V)
utilization aw apr. 39% (C03 =2.85mV/V)
If wz is in specified range, measuring amplifier
properly operates.
Note:
The test plug ordering number is V037426.B01.
