Alarm Messages and Codes
When an abnormal condition is detected by the IS1001 reader it generates an alarm message
that is sent to the communication ports. The alarms are sent to all available ports (unless the
CML0
command has been issued, in which case the alarms will not be sent to the local USB port.)
The following table is a list of the available alarms and their corresponding codes.
Code
Message
Description
1
Reader Date/Time Lost
IS1001 reader date/time setting has been lost.
Set reader real-time clock present date and time.
2
Reserved for MTS Mode
3
Reader Memory Error
IS1001 reader internal data memory reading/writing error detected.
Memory content is not guaranteed to be correct.
Unit requires repair.
4
Antenna Out Of Tune, Decrease
Capacitance
The IS1001 reader is unable to reach the desired antenna tuning
using the internal capacitors bank.
Manual antenna capacitance reduction is required.
5
Antenna Out Of Tune, Increase
Capacitance
IS1001 reader is unable to reach the desired antenna tuning using the
internal capacitors bank.
Manual antenna capacitance increase is required.
6
VTT Test Failed
IS1001 reader failed to detect VTT.
Verify antenna tuning and system noise level. VTT level adjustment
may be needed.
7
Antenna Current Low
IS1001 reader has detected that the antenna current is below the
user-defined specification.
Verify antenna tuning and
the reader’s DC power supply. Exciter
voltage level adjustment may be needed. Alarm threshold adjustment
may be needed.
8
Noise High
IS1001 reader has detected that the noise level is above the user-
defined specification.
Verfy antenna tuning. Verify surrounding environment for the cause of
the noise. Alarm threshold adjustment may be needed.
9
Tuning Capacitance Low
IS1001 reader has detected that the internal capacitors setting is
below the user-defined alarm threshold.
Verify antenna environment is not the cause of the problem (water
level significant change, metal objects in the antenna field, etc.).
Manual antenna capacitance adjustment may be needed. Tuning
capacitance low threshold adjustment may be needed.
10
Tuning Capacitance High
IS1001 reader has detected that the internal capacitors setting is
above the user-defined alarm threshold.
Verify antenna environment is not the cause of the problem (water
level significant change, metal objects in the antenna field, etc.).
Manual antenna capacitance adjustment may be needed. Tuning
capacitance high threshold adjustment may be needed.
11
Input Voltage Low
IS1001 reader has detected that the input voltage is below the factory
specifications. Alarm threshold depends on exciter voltage level
setting: 23 V for VE=5; 21 V for VE=4; 19 V for VE=3 and 18 V for
VE=1 and 2.
For IS1001-12V the threshold is 11.5 V.
Verify the
reader’s DC power supply.
