Select N.O. for closed relay operation with Sensor in Alarm condition (open when not in alarm
condition).
Contacts are held open for both N.O. and N.C. operation when the Sensor is not powered, and, for 3 to
5 seconds after power is applied to the Sensor during the initiate period. Normally Closed N.C,
operation is considered fail-safe operation.
The table below details the alarms and measurement conditions that trigger the Alarm Relay. Details
about these Alarms are found in Section 7
Maintenance , page 119.
Sensor Error Code Alarms
X101 Dirty Window Detection
X102 Out of calibration
X103 Detector block too hot
X104 Detector block too cold
X105
Case temperature too high
X106 Case temperature too low
X107 Sensor failure FAIL may be seen on the Sensor TEMP display
X108 Analog Output Current loop malfunction (open circuit)
X109 Dirty Window Detection malfunction
Measurement Condition Alarms
INV
Measurement Conditions are invalid for two color ratio temperature measurement.
When the Invalid Alarm (iALM) function is set to ON, this measurement condition becomes an alarm
and triggers the Alarm relay and the ALARM word on the Sensor rear panel
pINV pINV is only displayed when the Invalid Alarm (iALM) function is set to ON and Peak Picker or Track
and Hold is On, this condition becomes an alarm and triggers the Alarm relay and the ALARM word
on the Sensor rear panel.
Temperature displayed is Peak Picked or Hold Mode Temperature values from prior valid
measurement conditions.
4.8 Selection of a Power Supply for Sensors used with TSP Terminal
Strip Plates
When using a Modline 5 Sensor with the TSP Terminal Strip Plate, select a switching type power supply
that will provide reliable startup. The power supply output should remain at rated voltage during the
Sensor current loading that occurs at startup. Sensor displays and alarms will not properly start with
low voltage.
A dedicated Power supply for each Sensor is the simplest and best configuration. Section 4.9 RS-485
Multi-Drop Network Power Supply and System Wiring , page 75, provides instructions for using a
chassis mount 15 watt, 24 Volt DC Switching Power Supply supplied by IRCON. The part number for
this power supply is 551632.
Multiple Sensor installations may require more than one power supply. A single supply will not be able
to properly provide startup power to a large number of sensors. Limit the number of Sensors supplied
from a single power supply to no more than 2 or possibly 3. Dividing the Sensors into groups can
