Modline 5
UZ – Unit Zero Scale (Read Only)
Returns the Sensor’s zero scale temperature as defined its Model Number. An F or C is put on the
end as appropriate.
UF – Unit Full Scale (Read Only)
Returns the unit’s full-scale temperature as defined by its Model Number. An F or C is put on
the end as appropriate.
AC – Auto and Immediate Calibration Initiate (Read / Write) For 52, 5G, and 5R models.
See next paragraph for Models begging with 56 . See Section 5.5 Warm-up and Initial Setup , page 85.
Sets the number of hours between Systems Checks. A manual Check from the Sensor Keyboard or
by RS-485 Communication will start a new time period. Continuous interval setting should be 8
hours or greater. A 168 hour, 1 week, (or greater) automatic interval and manually initiated checks
are the recommendations that will provide minimal measurement interruption.
Range: 0 to 9999, 65535
A zero value disables this function. Values between 1 to 9999 sets the time period in hours.
A value of 65535 (FFFF
16
) causes an immediate Check to occur without changing the previously set
time period value.
AC – Auto and Immediate Calibration Initiate (Read / Write) For Models begging with 56.
Series 56 Models include a Self-Calibration feature performed as part of the power on routine.
Explanation of this feature is provided in Section 5.5 Warm-up and Initial Setup , page 85, under the
explanations for sensor parameters:
CHK -
(Models Beginning with 56) and HOUR - (Models
Beginning with 56).
Range: 0 or 168, 65535
A zero value disables this function (a Manual Initiation must be performed at least every 168 hours).
A value of 168 sets the time period between calibration checks to 168 hours (Factory setting)
A value of 65535 (FFFF
16
) causes an immediate Calibration to occur without changing the previously
set time period value. This is equivalent to a Manual Calibration at the Sensor Rear Panel.
RP – Relay Polarity (Read / Write)
Sets the polarity of the alarm relay. Set to 1 for “fail safe” operation. Contacts are held open with
power off or power on and in the brief warm-up state for either polarity.
Range: 0 or 1 (0 = N.O; to 1 = N.C.)
DT – Dirty Window Detector Warning Level (Read / Write)
This command is available only with the Dirty Window Detector option.
This command is the same as the Sensor Rear Panel WRNL. OFF turns the dirty window detection
function off. Course and Sensitive Warning Levels select a greater (CORS) or lesser (SENS) amount
of Sensor window transmission loss required to trigger a dirty window alarm.
Range: 0 to 2
Message Value:
0 = Dirty Window Detection Alarm Off
1 = Sensitive (SENS)
2 = Coarse (CORS)
SW – Switch Input Status (Read Only)
Command Returns the Sensor’s external switch status (Peak Picker reset and Hold mode select).
Range: 0 or 1 (0 = closed; 1 = open)
