Reference point check setpoint
During reference point measurement the mesh filter is moved into the measuring
beam (see Fig. 4.6 ; mesh at the measuring beam diaphragm). The opacity is meas­
ured, compared with the setpoint, and scaled to the signal range.
TC Variable type code SA Signal range start
N Zero point check value S Signal range 100%
SE Signal range end R Reference point test setpoint 70%
Table 7.10: Reference point check setpoint
Parameters Default value Unit
Reference point check setpoint 70 %
Table 7.11: Default value setpoint
The reference point test setpoint can be between 5 and 95 % of the value input to the
signal range. The measured value is divided by the setpoint calibrate in the factory
(~12% OP SP) and scaled according to the prevailing setpoint (see above, Tab. Ref­
erence point check setpoint "R"; generally 70%).
(Signal range start <- Signal range -> Signal range end;
see section 7.5.3.5 Signal range [
}
133] ).
The zero point setpoint is 0 (zero). This value is fixed and cannot be adjusted or
changed.
Control cycle step duration and control cycle interval
The control cycle step duration and the control cycle interval can be set for the control
cycle (0=automation checking cycle disabled). The setting is advised (generally 12 or
24 h) if the system is integrated into a monitoring system. This system can be pro­
grammed to respond if the values deviate from the specified values.
Parameters Default value Unit
Control cycle step duration 30 Seconds
Control cycle interval 0 Hours
