The TR can’t read a sensor

There is a major difference between two sensors
Test Button
The 'Test' button on the front panel may be used at any time to check that the TR-2100 is
operating correctly. When the button is pressed, a series of internal tests are performed and a
manual trigger is performed. If a local printer is connected, the system configuration and
record will be printed. Alternatively, Display Station can be connected to read and display
the data. If the TR-2100 detects a fault during these tests, it will switch on the 'Attention'
indicator. The cause of the problem can be found by reading the event log with Display
Station.
Disarm triggering
The 'Test' button may also be used to disarm all triggering within the TR-2100. This may be
required if maintenance is being performed on the monitored lines or transformers when
extraneous triggering could occur. By pushing the 'Test' button for 5 seconds, the 'On Line'
LED will go out, indicating that all triggering is disarmed. There is also a tone that changes
from a low to high pitch when the triggers disarm.
To rearm the recorder, press the 'Test' button again briefly. Since the recorder is not yet
armed, no test record will be generated. The Disarm function is also available in the
Recorder Configuration window of Display Station. Messages are placed in the alarm log
that indicates the time/date the system was disarmed and re-armed.
Status Outputs
The four solid-state status relay outputs are situated on the left of the lower input board.
These are specified as normally open contacts. The power relay is held on by the main
supply. The others are software controlled and switched on to indicate the designated
function.
The four defined functions are as follows:
Power
Duplicates the function of the front panel LED.
On Line
Duplicates the function of the front panel LED.
Triggered
The relay is activated while the TR-2100 is triggered with a minimum on-time of 500 ms.
This relay has a slightly different function if the recorder cross-triggering is enabled (see
Section 2).
