Parameter
Process High If Alarm 2 is a Process High Alarm, the
Alarm 2 value of the process variable at or
above which Alarm 2 will be active
(see Figure 4-2)
Process Low If Alarm 2 is a Process Low Alarm, the
Alarm 2 value of the process variable at or
below which Alarm 2 will be active
(see Figure 4-2)
Band Alarm 2 If Alarm 2 is a Band Alarm, the band
of process variable values, centred
on the (program) setpoint, outside
which the process variable will cause
this alarm to be active (see Figure
4-2)
Deviation If Alarm 2 is a Deviation Alarm, gives
Alarm 2 a value above (positive value) or
below (negative value) the (program)
setpoint. If the process variable
deviates from the setpoint by a
marging greater than this value, the
alarm becomes active (see Figure
4-2)
Alarm 2 Hysteresis Defines a hysteresis band on the
"safe" side of the Alarm 2 value
Scale Range For linear inputs only, defines the
Decimal Point decimal point position
Position
Scale Range For linear inputs only, defines the
Maximum scaled input value when the process
variable input is at its maximum value
Scale Range For linear inputs only, defines the
Minimum scaled input value when the process
variable input is at its minimum value
Manual Control
Enable/Disable
Setpoint Strategy Determines whether or not the
setpoint is adjustable in the normal
Base Mode display
Communications Enables/disables changing of
Enable/Disable parameter values via the
communications link
Controller Set-Up Defines the four-digit code required
Mode Lock Code to enter the Controller Set-Up Mode
