Eclipse 200 LT Series Instruction Manual

Eclipse 200 LT valves are manually opening valves that
automatically shut off the gas supply to a combustion sys-
tem when any interlocking limit switch opens. The valve
handle cannot be reset until the condition causing the
open switch is corrected and all limit switches are closed.
Typical limit switches include air pressure, gas pressure,
temperature limit, and flame monitoring contacts. In the
event of a power failure, the valve immediately closes.
Series 200 LT valves include two visual indicators of
"open" or "closed" position: a red "flag" visible in the plastic
dome on top of the valve; and the reset handle position as
indicated by cast markings on the operator case. These
valves also include two SPDT micro-switches that can be
used for auxiliary circuits. Two contacts are made when
the valve opens, and two are made when the valve is
closed.
