7.6 Troubleshooting Errors

Problem
UEOL message End of sensor lifetime
"ErrH" message Mismatch between the head and the gas detector
"Untn" message Due date sensor maintenance
"EE2P" message The internal memory E2Prom is not working
"EFLS" message The internal memory Flash is not working
"ErAN" message The internal memory Ram is not working
"EALM" The power supply of the detector is outside of range
message (from 12Vdc to 24Vdc)

8 Modbus and Serial Communications

8.1 Default Settings

1. Baud Rate: 19200 bps
2. Parity: None
3. Stop bits: 1

8.2 Modbus Registers

8.2.1 Read Input Registers
REV – 1.0
Table 7-3: RD-VRF Communicator Operating Errors
Possible Causes
Sensor's reading out of range
The sensor has a non-zero reading
The user has set a span value out of range
The user has set a threshold out of range
The user has set a hysteresis value out of range
The user has set a value out of range (range: 1-
247)
The user has set a non-admissible value
(admissible values: 9600, 19200, 38400, 115200)
Table 7-4: RD-VRF Trouble Shooting Errors
Possible Causes
34-5354-0001-14
Reasoning
The zero calibration was not performed
The zero calibration is performed but
with a warning notice
The span calibration is performed
but with a warning notice
The threshold is not memorized
The hysteresis is not memorized
The address is not memorized
The baud rate value is not
memorized
Possible Solution
Sensor substitution
Please perform pairing procedure
Check sensor functionality (with a gas test, for
example)
Please perform the reset procedure by using the
"0459" tech password
Please perform the reset procedure by using the
"0459" tech password
Please perform the reset procedure by using the
"0459" tech password
Please check the power supply on the + and –
terminals of the detector
