NOTE: Acetic acid will cause damage to
metal components, metal hardware, ce-
ramic 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 S104 re-
quires little or no maintenance other than peri-
odic calibration checks to ensure system
integrity. General Monitors recommends that
a schedule be established and followed.
NOTE: The system’s full two year war-
ranty will be voided if customer personnel
or third parties damage the system during
repair attempts.
Sensor heads exposed to the elements may re-
quire the accessory mounting threads to be lu-
bricated. Grease must not be used. As an
alternate, PTFE (teflon) tape may be used on
threads that do not contact the sensor hous-
ing.
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 com-
plete 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 sensor screen, to see it is clear of
water, oil, dust or paint which might clog
it.
l
The cable connections for tightness and
possible damage.
l
All sensor placements, to see that they 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.

Terminal Connections
The terminal blocks (TB) are located inside of
the housing and can by accessed by removing
the cover (figure 7, CE Mark units see figure
21). TB2 contains the three sensor connec-
tions, White (W), Black (B), and Red (R).
