Chapter 4 – Functions of the instrument

2.7. HOUR
This function includes a clock (hour, minutes) and an internal calendar (day, month and
year).
) Select the option and adjust settings if necessary.
2.8. REGULATOR LEARNING
2.8.1. Standard regulator learning
This function is only valid in the event of the installation of a regulator in the instrument.
It enables the determining of the time between two electronic regulator learning cycles.
When it is validated by "yes", the frequency (time or minutes) or the number of cycles
between two learning cycles is to be determined.
When the frequency or number of cycle values are at zero, the learning request
becomes manual, at the operator request by way of special cycle, or by the
programmable input 7.
The learning cycle allows the calculation of the three characteristic points of the
regulator (points at 20 %, 50 % and 80 % of the maximum pressure which can be
supplied by the regulator, value depending on the input air supply pressure).
) Select the option and adjust settings if necessary.
2.8.2. Without regulator learning
When the "Regulator learning" is not validated (No) there won't regulator characteristics
calculation (points at 20 %, 50 % and 80 %).
In this case two options arise in the "Fill mode" function: the fill mode in "Percent" or
"Control". These two types appear in the case of test in "Flow" mode.
2.8.2. 1) "Percent" type
In this mode, it must adjust the pressure instruction in percent of the full scale of the
regulator. Example: full scale of the regulator 4 bars, test pressure 1.5 bars then the
percentage will be 37.5 %.
2.8.2. 2) "Control" type
In this mode, it must adjust the hoped pressure instruction (real value in the configured
measurement unity).
The electronic regulator is correcting two times the pressure rise ramp during the fill.
This function allows making a correction of the pressure instruction according the flow.
When this correction is too important, an alarm "< Min. Pressure" is activated.
During the stabilization and test phases, no instruction correction is realized.
