Страница: 14 / 39

NOTE: Acetic acid will cause damage to
metal components, metal hardware,
ceramic IC’s, etc. If damage results from
the use of a sealant that outgases acetic
acid (RTV silicone), the warranty will be
void.
Once correctly installed, the Model S216A
requires little or no maintenance other than
periodic calibration checks to ensure system
integrity. General Monitors recommends
that a schedule be established.
NOTE: The system’s full two year
warranty will be voided if customer
personnel or third parties damage the
system during repair attempts.
Sensor heads exposed to the elements may
require the accessory mounting threads to be
lubricated. Grease
must not be used. As an
alternate, PTFE (teflon) tape may be used on
threads.
NOTE: Do not use any material or
substance on threads that contact the
sensor housing.
The removal of particulate matter from
sensor accessories may be done through the
use of an appropriate halogen-free solvent.
Water or ethanol are examples of suitable
solvents. The accessories should be
thoroughly dried, with compressed air if
necessary, before refitting to the sensor
body.
General Monitors recommends that the
complete system, including all alarm
circuitry, be tested at least annually.
Some typical items to check during
maintenance examinations are:
l
The sensor mounting, to see it is secure.
l
The cable connections for tightness and
possible damage.
l
The sensor screen, to see it is clear of oil,
water, dust or paint.
l
All sensor placements are up to date with
the layout of the plant (e.g.
modifications to the plant).
l
The complete system, to see it has a back
up supply for the full prescribed time.
