BASLER ELECTRIC SR4A-2B15B3A Static Voltage Regulator

Once the list of annunciation messages has been viewed, it may be cleared by pressing the Reset

pushbutton. If a condition that LED to an annunciation is still present when the alarm message screen is

cleared, then a new annunciation message will be generated.

Pressing the Reset pushbutton will also send the display back to the Metering screen. Furthermore, the

alarms message on the Metering screen will also be cleared. However, if the user leaves the alarm

message screen by pressing  the Left, Right or Up scrolling pushbuttons, then the annunciation

messages list remains intact. This allows the user to maintain a short history of annunciations. In addition,

the alarms message on the Metering screen will also remain. The disadvantage of this is that the

metering screen would no longer indicate that a new annunciation occurred because the alarms message

would always be present.

Screens with Special Editing Modes

There are several screens that operate differently while in the edit mode. OPERATE_1 (1.1),

BAUD_RATE (8.1.1), and MODBUS (8.1.2) are examples of such screens. In each case, any changes

made to a setting are not used by the system (nor saved in nonvolatile memory) until the Edit pushbutton

is pressed again.  The programmable inputs for output relays 1 through 4 work in the same manner.

These are on screens RELAY_1 (7.5.1) through RELAY_3B (7.5.9).

The REG_GAIN (3.1) screen also operates in a different manner when in the Edit mode. The first four

parameters on this screen represent a table containing twenty sets of predefined PID values and one set

of user-definable values. The first of these, STAB SET #, which means stability settings number, is the

index to the table. The second, third, and fourth parameters (AVR/FCR Kp, Ki, and Kd), are the actual

entries in the table. Stability setting numbers 1 to 20 are the predefined values, and 21 is the set of user

definable values.

Editing these parameters works as follows:  As long as STAB SET # is set to 21. then AVR/FCR Kp, Ki,

and Kd may be individually edited and customized. The values displayed are not used by the system until

they are saved by pressing the Edit pushbutton. This means that if a change is aborted by pressing the

Reset pushbutton, the PID numbers currently being used by the system remain unchanged.

If STAB SET # is 1 to 20. then AVR/FCR Kp, Ki and Kd may not be edited from the display (although the

cursor can be moved to their display fields). If the STAB SET # is changed, the values shown in the

display fields will not change until the selected STAB SET # is saved. When the STAB SET # is saved,

the table entries are saved, used by the system and displayed on the LCD.

If the DECS-200 is using the user-defined values previously set at STAB SET # 21 and a STAB SET # of

1 to 20 is saved, the user-defined values are lost. The next time that user-defined values for STAB SET #

21 are required, they must be manually entered and then saved. It is assumed that the table entries for

STAB SET # 1 to 20 will be used as starting points from which users will arrive at their own customized

values after the selected starting point has been saved (and thus copied into STAB SET # 21).

Menu Tree

The menu tree has eight branches:

1. OPERATING. Displays mode status and on or off status (AVR, FCR, var, PF, etc.)

2. SETPOINTS. Display and setting of mode values (AVR, FCR, var, PF, etc.)

3. LOOP GAINS. Loop gains for each element are set here (Kp, Ki, Kd, Kg)

4. METERING. Real-time metering of user-selected values and alarm messages.

5. PROTECTION. Display and setting of protective function parameters such as pickups.

6. LIMITERS. Display and setting of system limiters (OEL, UEL, etc.)

7. SYSTEM PARAMETERS. Display and setting of system parameters. This menu item consists of nine

sub-branches:
