Upper display: OFF/ON

Select ON and press the FUNC key in order to acknowledge the alarm. ON = Alarm Acknowledged

OFF = Alarm Not Acknowledged

Software Key (Skipped if n1 = 0 or 1) Lower display: nn

Setpoint Threshold

Lower display: Su

Upper display: Setpoint threshold value

Range: Span limits (From "S1" to high span limit when C1 = Hi.Lo)

Setpoint1 Threshold (Available when C1 = Hi.Lo) Lower display: S1

Upper display: Setpoint threshold value

Range:

From low span limit to "Su"

Setpoint Threshold Hysteresis

Lower display: HS

Upper display: Hysteresis value

Range: From 0.1% to 10.0% of span value or 1 LSD

Alarm Threshold (optional)

 

(Available only if P1=AL.P, AL.b or AL.d.)

 

Lower display: AL

 

 

Upper display: Alarm threshold value

 

Range:

 

 

 

Span limits

(if process alarm

P1 = AL.P)

From 0 to 500

(if band alarm

P1 = AL.b)

From -500 to 500

(if deviation alarm

P1 = AL.d)

Alarm Hysteresis (optional)

 

(Available only if P1 = AL.P, AL.b or AL.d)

 

Lower display: HA

 

 

Upper display: Hysteresis value

 

Range:

or 1 LSD

 

Serial LInk (optional)

The device can be connected to a host computer via serial link.

The host can put the device in LOCAL (parameters are controlled via keyboard) or in REMOTE (functions and parameters are controlled via serial link).

REMOTE is signified by the decimal point to the left of "RMT" which is on the right side of the numeric display.

Via serial link it is possible to read and/or to modify all the operative and configuration parameters.

The following conditions must apply to implement this function:

1)Configure parameters L1 through L4 with the front keyboard

2)The device must be in the Operating mode.

Control output is OFF during the download procedure.

At the end of configuration downloading procedure the device preforms an automatic reset and returns to normal condition.
