6 MAINTENANCE
Maintenance is a very important activity that should be done at the proper time intervals, which
are discussed below.
6.1 GENERAL
The AMC-VersaTox sensor/transmitter unit should be brushed or wiped as required, depending
on the rate of accumulation of any dust or dirt.
To avoid sensor damage, the unit MUST NOT be submerged in any liquids. Hosing or
splashing of the unit with any liquids must also be avoided.
6.2 SCHEDULED CALIBRATION
Scheduled calibration is critical in maintaining proper function of gas sensor/transmitters.
It is recommended that the AMC-VersaTox be calibrated a minimum of twice a year.
As mentioned, Armstrong Monitoring offers a number of different maintenance plans to suit your
requirements see section 5.2.
6.3 SENSOR/TRANSMITTER REPLACEMENT
When its signal is greatly reduced or unstable, the sensor/transmitter replacement is required;
see section 2.1 for replacement sensor P/N.
Please note that in some instances the sensor itself is not replaceable. The circuit card with the
sensor is replaced, please contact the factory.
Caution:
It is recommended to turn off the power to the sensor/transmitter before replacing the
board.
Note:
30 minutes is required for a new sensor to stabilize before calibration.
