WIRELESS H2S TRANSMITTER (WT SERIES) - USER GUIDE
25.
GENERAL MAINTENANCE
The Wireless H2S Transmitter is easy to maintain and does not require
periodic system checks. The transmitter generally only needs a yearly visual
inspection to monitor the following:
•
Is the Battery life still 2.9 V or above? (Check more frequently if using
shorter transmit interval)
•
Is the transmitter still securely fastened to the mounting location?
•
Are there any visible signs of corrosion, cracks, or residue build-up on
the unit?
•
Has anything about the intended use of the original application
changed?
If the transmitter is securely fastened, with no signs of corrosion, cracks, or
residue build-up, or if nothing has changed about the location of its intended
use, it should continue to operate within the designed specification.
If the transmitter is not securely fastened; if there are signs of corrosion,
cracks, residue build-up; or if there has been a change to the location of its
intended use resulting in undesirable performance, contact the manufacturer
for service instructions.
Cleaning: To prevent static discharge, wipe the outer casing with a damp cloth
only.
The H2S sensor opening must not be obstructed in any way. Check and clear
off any debris.
Bump Test schedule
H2S Transmitter users are recommended to periodically perform bump tests in
accordance with organizations safety policies to verify accuracy and acceptable
device performance.
Calibration schedule
The sensor must be calibrated on site prior to use due to local geographical
characteristics.
H2S Transmitter users are recommended to periodically perform calibration of
zero and span in accordance with organizations safety policies to verify
accuracy and acceptable device performance.
Sensor Module replacement schedule
The accuracy of the sensor module is certified for up to 2 years. Please replace
the module based on the installation date. Reference the “Days In Service”
register tag as to properly schedule sensor replacements.
Sensor element should be kept free of airborne objects, including any
debris that could potentially cover or obstruct the sensor. Keeping the
sensor free of foreign articles will allow for proper WT-H2S operation.
A brief inspection during scheduled maintenance should be sufficient,
however dependent upon the location and the environment in which
the device is installed, more frequent inspections may be warranted.
