Protege System Controller Reference Manual

Enabled Control PGM
Enabled Control PGM is set when the value compare function is to run and will operate only when the enabled
PGM is on. If no enabled PGM is set the value compare function will run continuously. This allows the value
compare function to operate only during the times that the resulting PGM is required.
FN001 Enabled
pgm: --000:00
To modify the enabled PGM, use the settings as explained in section Entering PGM and PGM Groups (see page
345).
High PGM
The High PGM output will activate when the input data register (usually an input from an analog register) is
above the set point plus the hysterisis value and has been for the duration of the hysterisis time. The high PGM
will turn off if the input value is below the set point value.
FN001 High
pgm: --000:00
To modify the High PGM, use the settings as explained in section Entering PGM and PGM Groups (see page
345).
Low PGM
The Low PGM output will activate when the input data register (usually an input from an analog register) is below
the set point minus the hysterisis value and has been for the duration of the hysterisis time. The low PGM will
turn off if the input value is above the set point value.
FN001 Low
pgm: --000:00
To modify the low PGM, use the settings as explained in section Entering PGM and PGM Groups (see page
345).
Base Data Register
The Base data register is used as the first register in the list of registers used to configure, program and control
the Value Compare. The only registers that are not included in the base registers are ones that must link to an
analog input or analog output for external sensors (Temp, Daylight (LUX), Water Level). A base data register
setting MUST be set to ensure the system can pick up the set points and data values.
FN001 Base data
reg: 00000
To modify the base data register (00000 to 65535, use the keypad as explained in section Entering Decimal
Numbers (see page 341) and press [ENTER].

0 Input Value Set Point
The input value set point is used to determine at what point the comparison input register
value used in the calculation is high or low. The Input Hysterisis value is added or
subtracted from the set point to prevent an oscillation on the output PGM's.
