Warm-up and Initial Setup
5.5.1
Series 5R, 5G, 52 Power On and Warm-up
When power is applied to the Sensor, a three to five second initiate condition occurs. All segments of
the dot matrix TEMP display and all word and symbol indicators are lit. The alarm relay is always held
open
during this short period.
After application of power, a warm-up time of approximately 5 to 15 minutes is required for the Sensor’s
infrared detector and/or electronics. The Sensor Rear Panel Alarm indicator will be lit and Error Code X104
(Detector Cold) displayed when the
▲
arrow is depressed.
During the warm-up time, temperature
measurements can be made and outputs are operational. However, the Alarm signifies that the
temperature indication may not be accurate.
Temperature indications will be accurate after the Alarm
indicator has turned off when warm-up is completed.
If there is a brief power outage, Sensors may restart
and go into the initiate and warm-up conditions described above.
The Sensor Check function should not be initiated until the Sensor has warmed up and the Alarm indicator
has turned off.
An Out of Calibration Alarm (X102) may occur if initiated during warm-up. If this Alarm
occurs, repeat the Check.
5.5.2
Series 56 Models Power On and Warm-up
Series 56 Models include a Self-Calibration feature which is performed as part of the power on routine.
5.5.3
Initial Rear Panel Display
After the warm-up period is over, you should observe one or more of the Modline 5 Sensor responses
described below on the TEMP display and at the outputs. During initial setup, because the Sensor is not
adjusted for the process, these initial displays are expected.
1.Target Within Range
— If the Sensor is viewing a temperature within its range, it will display a
temperature value. Equivalent analog signals will be supplied to any devices connected to the analog
outputs (e.g., recorder or remote indicator). If initial setup has not been set to match operation to the
process, the displayed temperature and analog outputs will not be a true measurement of the target
temperature.
2. LOW / HIGH Indication
— If the measured temperature is below or above the Sensor temperature
range limits LOW or HIGH will be shown on the temperature display. The Alarm Indicator does not
light because these are normal conditions.
3. INVALID — An Invalid condition will be indicated any time the sensed infrared radiation is
considered to be inadequate for two color Ratio Sensor measurement. The word INV is indicated on the
TEMP display. If the Invalid Alarm (iALM) is set to On, the Alarm Relay will be in alarm condition and
the word Alarm lit on the Sensor rear panel.
5.5.4
Initial Sensor Setup
Initial Sensor setup should follow the menu orders indicated in the following instructions. Menu
navigation is shown using the
&
▲▼
symbols for Enter and Up / Down arrows. The menus and
functions available and the sequence in which they appear depends on the Sensor Model and the
purchased options.
A function variable is expressed as a word or as a number. A function variable may be changed from
State A to State B or from a higher or lower numerical value by using the Up / Down arrows.
