3. ប្រតិបត្តិការ
The Model 150 Process Indicator accepts a 4-20mA input signal from a sensor such as a pressure transmitter, temperature sensor or load cell transmitter. The instrument is powered entirely from the loop and, therefore, requires no external power or internal batteries.
The instrument is fully programmable with all operating parameters and calculation constants programmable from the front panel (see Section 4.1). The setup parameters are stored in a non-volatile memory and are retained indefinitely in the event of a power loss.
3.1 ការបង្ហាញ
The display of the Model 150 comprises of:
Process Signal Bar Graph Process Variable Numeric Display
3.1.1 Signal Bar Graph
The signal bar graph displays the input signal as a percentage.
Inputs of 4mA and 20mA can be programmed to correspond to 0% and 100% respectively, or can be inverted so that 4mA will correspond to 100% and 20mA will correspond to 0%.

ប្រតិបត្តិការ ១៣
3.1.2 អថេរដំណើរការ
The process variable is a 7 digit numeric display which can be spanned, during setup, to read in any engineering units. The process variable is displayed with 4½ resolution in respect to the maximum reading.
សម្រាប់អតីតample, if the maximum reading is 1234567, the display will show up to 5 digits plus trailing zeros. At different inputs the following will be displayed:
1234567 will be displayed as 1234500; 234567 will be displayed as 234500.
However, if the first digit is greater than 1, then up to 4 digits only will be displayed with trailing zeros. For example, if the maximum contents is 2345678, then at different inputs:
2345678 will be displayed as 2345000; 345678 will be displayed as 345000.
CALCULATION OF THE PROCESS VARIABLE
For a linear signal/process variable relationship, the contents is calculated as follows:
Process Variable = (Span) x (% Signal) + Offset
where the Span and Offset are constants programmed during programming

The Model 150 has 4 alarm outputs: Signal

High-High (HH) High (H) Low (L) Low-Low (LL)

The alarms can be assigned to signal or process variable which is done during programming (see Section 4.1). Each alarm is individually programmed as a percentage (0-100%) of signal or process variable.
All of the alarms have open collector outputs and are separately isolated via optoisolators. The outputs are internally protected against voltage spikes បណ្តាលមកពី relay និង coils ។
3.4.1 Types of Alarms
3.4.1.1 ការបញ្ចេញសំឡេងរោទិ៍
The Model 150 can be programmed for the alarm outputs to operate in one of two ways:
1. The alarm outputs can energise (switch on) during an alarm condition, or; 2. The alarm outputs can de-energise (switch off) during an alarm condition.

ប្រតិបត្តិការ ១៣
3.4.1.2 High Alarms
The high alarms will be activated when the signal or process variable increase above the high alarm setpoints. These alarms will be deactivated when the value falls below these programmed setpoints.
When setting the alarms, the high-high alarm should be set higher than the high alarm.
3.4.1.3 Low Alarms
The low alarms will be activated when the signal or process variable falls below the low alarm setpoints. These alarms will be deactivated when the value exceeds the programmed setpoint.
Similarly, when setting the low alarms, the low-low alarm should be set below the low alarm.
3.4.2 Alarm Deadband
To prevent an alarm toggling on and off when the signal is close to the setpoint, a user programmable deadband is provided. The deadband is a percentage (0-100%) of the maximum signal or process variable.
Exampលេ 1 ។
If the low alarm is set to 20% and the deadband is set to 5%, the alarm will be activated when the value reaches 20%. The alarm will then stay activated until the value increases above 25%.
Exampលេ 2 ។
If the high alarm and deadband are set at 80% and 5% respectively, the alarm will be activated at 80% and will stay activated until the value falls below 75%.

3.4.3 Alarm Action
When an alarm condition exists the Model 150 will act in the following way:
1. The appropriate alarm output will be activated.
2. The display will flash the name of the alarm.
3. In some cases these alarms may be acknowledged from the front panel. This will depend on whether they are programmed as continuous or acknowledgeable alarms. This is set up during programming (see Section 4.1).
The differences between acknowledging continuous and acknowledgeable alarms are described in the table below.

Acknowledgeable Alarms

Continuous Alarms

1. These alarms are acknowledged 1. A continuous alarm cannot be

2. The flashing on the LCD cannot be stopped and will keep flashing until the alarm condition no longer exists.

3. Once the alarm is acknowledged, the alarm output will be deactivated.

3. The alarms will only be deactivated when the signal (or process variable) is outside alarm conditions.

Note that acknowledging the LL alarm will also acknowledge (and deactivate) the L alarm. Similarly, acknowledging the HH alarm will also acknowledge (and deactivate) the H alarm.

3.5 NON-LINEARITY
The Model 150 can be programmed to correct for the non-linearities between the signal input and the process variable. A correction table, which corrects for non-linearities, can be programmed during setup. This table works as follows:

The user programs a normalised (between 0 & 1) input signal.
The user programs the corresponding process variable (output) point, which is also normalised.

Up to 25 points can be programmed this way. The number of points programmed is user determined.

The Model 150i performs a linear interpolation between these points to obtain a profile of input signal versus corrected output.

The user can program up to 25 points. However, the values at 4mA or 20mA which are set at 0 and 1 respectively, are not programmed. It is not always necessary to program all 25 points, as it will depend on the shape of the tank.

ប្រតិបត្តិការ ១៣
3.6 ការត្រង
Input fluctuations in the signal can interfere with the stability of the signal and process variable readings. For this reason, the Model 150 has a digital filter which will average out these fluctuations and enable accurate readings.
The degree of filtering of the input signal can be adjusted, depending on the amount of fluctuation and the particular application. Values from 1 to 99 can be programmed, where 1 corresponds to no filtering and 99 corresponds to heavy filtering. Such flexibility in filtering means that highly accurate and stable readings can be obtained.
When programming the degree of filtering, it is advisable to start with no filtering (the factor equals 1) and gradually increase until a steady reading is obtained. It is important that the filtering is not too heavy because this will cause an overdamped response.
The graph on the following page shows the time to reach 90% and 99% of a new reading for a step change in input signal.

When connecting the Model 150, it is good practice to use shielded cable. The shield should be connected to earth at one end of the cable. The other end of the shield should not be connected.
This wiring practice is mandatory in order to comply with the requirements for Electromagnetic Compatibility as per EMC-Directive 2014/30/EU of the Council of the European Community.

All printed circuit boards must be repaired by Contre Ltd.
