Parameter Block F
Select limit values and their event classes in
accordance with application requirements.
Parameter Block G
Adjust display filters, if required. Normally, the default
values can be used.
Parameter Block H
See “Automatic Zero Setting”. Maintain default values
for the time being. Do not start automatic zero setting
before calibration is effected.
Parameter Block K
For calibration, the maintenance parameters are
irrelevant. The default values are useful suggestions.
Parameter Block N
Measuring at discharge point (CPD) should normally be
activated (N 01, N 02). For automatic belt influence
compensation (BIC) and belt drift display, a special belt
circuit sensor and a metal sensor area on belt are
required. If these are not available, set Parameter N 03
to NO. Disconnect BIC during initial commissioning.
Parameter Block O
The event classes are selected for a standard scale. If
messages O 04, O 06 and O 07 have been modified
for training, reset to default.
Functional Check
1. Start weigher and conveyor belt.
Starting depends on selected start source B 06 .
Acknowledge Message E1.
2. As running display, a rotating point appears in
top left display field.
If not, Parameter Vmin (F 09) is set too high or
START key has not been operated.
3. Interpret event messages, if any, as shown in
Chapter 10 and remedy fault.
4. Call Service messages.
(a) Tachometer
If measurement is ON (B 03 = DI7), speed
transducer output frequency must be below
3000 Hz. Compare value with Spec Sheet. If
frequency heavily varies at constant belt
speed, there is too much space between
speed transducer NAMUR sensor and
gearing. See also “Check of Belt Speed”.
(b) wz
The unnormalized output value of load cell
amplifier must not exceed 2.85mV/V, not even
with nominal platform load. Value changes
with varying load on platform (e.g. check
weight).
Value excessive:
–
Load cell overloaded
–
Tare balance weight, if any, improperly set
Value negative:
–
Load cell improperly connected
–
Tare balance weight, if any, improperly set
(c) aw
Load on load cell in percent related to the total
of load cell rated capacities.
Interpret as under Item b). At nominal belt
load, aw should not exceed 100%.
5. If all else fails, see “Test Plug” item.
