CLASSIC 800 Product Manual
I. GENERAL INFORMATION
With proper installation the CLASSIC 800 will require v ery little maintenance, as there are no mov ing parts
subject to wear. Following a few simple guidelines will ensure years of dependable serv ice.
1 . Spin Cover
In accordance with CSA, FM, UL and local codes the spin cov er must be properly installed at all times. The
threads of the cov er should be lightly coated with a lubricating compound to prev ent seizing, freezing and
corrosion. Spray lubricants are not recommended.
2. Process and Conduit Connections
• In accordance with CSA, FM and local codes all power and communication wiring should be
enclosed either in conduit or an approv
ed jacketed cable. Ensure that the electrical connection
made at the enclosure of the CLASSIC 800 meets all codes and requirements.
•
As described in detail in Section 2 “Installation Guidelines” , ensure that the sensor is installed
with the proper orientation, to the proper depth and coat threads with a thin layer of thread tape or
sealant/lubricant.
• Most Fault conditions and reported “failures” are actually caused by loose, broken or improper
electrical connections. Ensure that the connections for the sensor, input power and relay output are
correct and secure.
3. Sensing Elements
•
The alloy (Stainless Steel, Titanium, Hastelloy, etc.) sensors require no periodic maintenance, but
any deposits or scaling should be remov
ed from the sensor tip as necessary. Use the appropriate
cleaning dev ice or material relativ e to your process (example: cloth, brush, wire brush, steel wool,
sandpaper, water, detergent, compatible solv ents to the sensor material, etc.).
Notes:
As described in detail in
Section 2 “Installation Guidelines”
, proper physical installation of the
sensor is critical to the operation of the switch/transmitter in terms of sensitiv ity and response time.
Because sediment will collect at the bottom of any v essel, and entrained gases will always collect
at the top of any v essel, ensure sensing tip is inserted to a point where it will be constantly and
fully exposed to the desired process media. Av oid locations where sediment may accumulate and
ev entually isolate the sensing tip from the process.
4. Electronics Module
•
Proper ESD (electrostatic discharge) procedures should be observ ed when handling the Electronics
Module.
• A remote electronics enclosure system is required when ambient temperatures exceed 65°C
(1 49°F) where the electronics will be mounted. The combination of sev
eral factors relativ e to
temperature should be considered when mounting the switch/transmitter:
A. High temperatures of the process material, which may ov er time, become a conv ectiv e heat
source.
B. High ambient temperature, which may prev ent the surrounding air from cooling or insulating the
electronics.
C. Radiant heat, if the switch/transmitter is installed in direct sun in a hot climate, or near a heat
source.
D. Mechanical features of the installation such as pipe insulation, heat sinks, cooling fans, etc.
