P 4

=

Alarm Standby (mask) Function

(Skipped if option is not available or P1= none)

OFF

=

Standby function disabled

On

=

If the alarm is programmed as band or deviation, this function masks the alarm condition at start up and after a “Su” (limit threshold) changement until the process variable reaches the alarm threshold, plus or minus hysteresis. This standby function masks a Process Alarm condition at start up until the process variable reaches the alarm threshold plus or minus hysteresis.

PF = Time Constant of the Filter

applied to the Measured Value for

Alarm Action

(Skipped if option is not available or P1 = none) Range: From 0 (filter OFF) to 8 seconds

(First order filter with selected time constant.)

n 1 = Safety Lock

0= UNLOCKed. The device is always UNLOCKed and all parameters can be

modified.

l= LOCKed. The device is always LOCKed and no parameters can be modified

From 2 to 9999 = This number is a password, to be used in run time (see “nn”), to LOCK/ UNLOCK the device.

t1 = Timeout Selection

tn10 = 10 second timeout

tn30 = 30 second timeout
