Process High

If Alarm 2 is a Process High Alarm,

Process Low

If Alarm 2 is a Process Low Alarm, the

Input Range Minimum

(see Figure 2-2)

 

 

 

 

 

 

Band Alarm 2

If Alarm 2 is a Band Alarm, the band

0 to input span from

5 units

 

of process variable values, centred on

(program) setpoint

 

 

the (program) setpoint, outside which

 

 

 

the process variable will cause this

 

 

 

alarm to be active (see Figure 2-2)

 

 

 

 

 

 

Deviation

If Alarm 2 is a Deviation Alarm, gives

￿input span from

5 units

Alarm 2

a value above (positive value) or

(program) setpoint

 

 

below (negative value) the (program)

 

 

 

setpoint. If the process variable

 

 

 

deviates from the setpoint by a

 

 

 

margin greater than this value, the

 

 

 

alarm becomes active (see Figure

 

 

 

2-2)

 

 

 

 

 

 

Alarm 2

Defines a hysteresis band on the

1 to 250 units

1 unit

Hysteresis

“safe” side of the Alarm 2 value

 

 

 

 

 

 

Scale Range

For linear inputs only, defines the

0 (xxxx), 1 (xxx.x), 2

1 (xxx.x)

Decimal Point

decimal point position

(xx.xx) or 3 (x.xxx)

 

Position

 

 

 

 

 

 

 

Scale Range

For linear inputs only, defines the

￿1999 to 9999

1000

Maximum

scaled input value when the process

 

 

 

variable input is at its maximum value

 

 

 

 

 

 

Scale Range

For linear inputs only, defines the

￿1999 to 9999

0000

Minimum

scaled input value when the process

 

 

 

variable input is at its minimum value

 

 

 

 

 

 

Manual Control

 

0 (Disabled) or

0

Enable/Disable

 

1 (Enabled)

(Disabled)

 

 

 

 

Setpoint Strategy

Determines whether or not the

0 = not adjustable,

1

 

setpoint is adjustable in the normal

1 = adjustable

 

 

Base Mode display

 

 

 

 

 

 

Communications

Enables/disables changing of

0 (disabled) or

1

Enable/Disable

parameter values via the

1 (Enabled)

(Enabled)

 

communications link

 

 

 

 

 

 

Controller Set-Up

Defines the four-digit code required

0 to 9999

10
