70 TRACE 1310 Auxiliary Oven Instruction Manual
Carry out the valve and system plumbing according to the appropriate plumbing diagram for
your system setup.
The valves in the TRACE 1310 Auxiliary Oven are gas-actuated. The valves are controlled by
solenoid valves that are turned on and off by timed events. Each solenoid valve uses one timed
event. Once a valve occupies a timed event, this timed event is removed from the list of
external events that can be added to a run table. You can configure a valve to be a gas sampling
valve or a switching valve.
Gas sampling valves have two positions: Load and Inject.
Switching valves have two positions: On and Off. Switching valves are plumbed so that the
counter-clockwise position is Off and the clockwise position is On.
 To test the valves
1. Configure the valve and rotate it clockwise and counter-clockwise.
2. Ensure that the valve moves freely in both directions.
3. Inspect the valve stop when the valve is in both positions to ensure that the stop is at the
movement limit on each side.
