P24 = Alarm 1 action

Available only when P9 = "AL1.P", "AL1.d" or

"AL1.b".

dir = direct action (relay energized in alarm condi-

tion)

rEV = reverse action (relay de-energized in alarm

condition)

P25 = alarm 1 stand-by (mask) function

Available only when P9 = "AL1.P", "AL1.d" or

"AL1.b".

OFF = stand-by (mask) function disabled

On = stand-by (mask) function enabled

NOTE: If the alarm is programmed as band or

deviation alarm, this function masks the alarm

condition after a set point change or at the

instrument start-up until the process variable

reaches the alarm threshold plus or minus

hysteresis. If the alarm is programmed as a

process alarm, this function masks the alarm

condition at instrument start-up until the process

variable reaches the alarm threshold plus or

minus hysteresis.

P26 = Alarm 2 action

Available only when P11 = "AL2.P", "AL2.d" or

"AL2.b".

dir = direct action (relay energized in alarm

condition)

rEV = reverse action (relay de-energized in alarm

condition)

P27 = Alarm 2 stand-by (mask) function

Available only when P11 ="AL2.P", "AL2.d" or

"AL2.b".

OFF = Stand-by (mask) function disabled

On = Stand-by (mask)function enabled

NOTE: for more details to stand-by (mask) function,

see P25 parameter.

P28 = OFFSET adjustment added to the

measured value

This parameter allows to set a constant OFFSET

throughout the readout range.

It is skipped for linear inputs

- For readout ranges with decimal figure, P28 is

programmable from -19.9 to 19.9.

- For readout ranges without decimal figure, P28

is programmable from -199 to 199.

P29 = Displayable protected parameters

This parameter is skipped when P17 = 0.

OFF = Protected parameters cannot be displayed.

On = Protected parameter can be displayed.

P30 = SMART function

This parameter is skipped when none of the

outputs is programmed as control output.

0 = SMART function disabled.

1 = SMART function is NOT protected by safety

lock.

2 = SMART function is under safety lock protection.
