1Warnings
The 7115 contamination trap is design for use with pressure controllers, calibrators and
regulated pneumatic pressure systems. These systems control a supplied pressure source
and output them to a unit under test. The 7115 is connected between the controller and the
UUT. Please observe all warnings and safety instructions when dealing with high pressure
supplies and outputs. Please ensure that all users of the instrumentation have fully read and
understood operating instructions and safety procedures for handling high pressure systems.
Observe all warnings before operating pressure calibration systems (ie 8030, RMTEG etc).
The 7115 shall only be used with clean dry air or nitrogen.
Never use hazardous media as pressure medium.
Do not exceed 210bar input to the 7115.
Before pressurisation of the 7115, check all components and connections are
in good condition, fully functional and that all screw fittings are firmly. All
connections should be suitable for the applied maximum pressure.
In the case of an error in connections or use, a high pressure or vacuum may
be on the input and output connections. Ensure supplies are vented before
working on pressure connections.
During operation, do not disconnect the 7115 when pressure is being applied.
When working on and with the device wear safety glasses.
Connections and UUTs damaged from overpressure can cause high velocity
shrapnel.
Note that when a device (such as an analogue pressure gauge) is to be tested or calibrated,
it is referred to as the UUT (Unit Under Test) in this manual. The UUT should be connected
to the 7115 using suitable fittings and hose ensuring they are rated for at least the maximum
pressure available from the pressure controller or calibrator supplying pressure.
Time Electronics Ltd do not assume liability for damages that arise from incorrect use of the
instrument device or from disregard of the information contained in this manual.

2Introduction
The 7115 is a contamination trap designed to protect pressure equipment, such as
controllers, calibrators and pressure generators, from impurities, liquids (water, oil etc.) and
residues released by manifolds, pressure gauges, pressure transmitters and other process
instruments under test.
It has been designed primarily for use with the Time Electronics 8030 pressure controller.
The 7115 provides a level of protection for the internal system components that require
mechanical operation to be smooth and unobstructed, to ensure correct operation of the
controller. Contamination can damage the 8030 control mechanisms.
During transitions from a high pressure setpoint to a smaller one, liquid and residues present
in the pneumatic system may flow into the 8030.
For example, consider an 8030 controlling to 20 bar on a UUT, and the setpoint is then
changed to 2 bar. In order to decrease the pressure, the 8030 must remove air from the
system. Such air removal can cause liquids and residues present in the UUT to flow into the
8030, damaging it and compromising the operation of the control valves. This may also
occur when selecting negative setpoints (vacuum).
The contamination trap must be placed between the 8030 and the UUT in order to avoid that
liquid (water, oil etc.) and residues from these process instruments damage the internal
system of the controller. The 7115 is a trap that is supplied as standard with the 8030
controllers.

3Using the 7115
The Contamination Trap must be used always in the upright position to prevent liquid from
flowing into the pressure controller or calibrator.
This guide will show the connections and usage with the 8030/8030B Pressure Controllers.
8030B is the module version of the 8030.
The CLEAN port must be connected to the 8030 pressure controller. The DIRTY (UUT) port
must be connected to the manifold, manometer, pressure switch, transmitter or other
process instruments that will be calibrated or adjusted.
Example Connections:
The 8030 should be used with a liquid trap to ensure that no contamination reaches the
instrument. UUT’s can be dirty, with oil and water capable of getting into hoses and affecting
instrument performance.
Minimess hoses are supplied for connection from the 8030 to
the 7115. An additional hose is supplied for connection from
the 7115 to the UUT. If an manifold is supplied this will be a
minimess to minimess type. A minimess to ¼ BSP or ¼ NPT
hoses will be supplied if required.
The 7198 pressure adaptor kit can also be used to make
connections from the 7115 to various UUTs with different
thread types.

4Cleaning and Maintenance
When the liquid accumulated inside the contamination trap reaches the level of the boundary
line, the liquid can be removed as follows:
1. Disconnect both hoses from the contamination trap.
2. Using two 19 mm (3/4”) spanners loosen the contamination trap via the hexagonal
nuts so that it may be dismantled by hand.
3. Hold the water trap over a sink or receptacle and allow the water/contaminant to
flow out.
4. Dismantle the water trap completely.

5. Using clean water, rinse the components.
6. Using clean tissue dry thoroughly, ensuring all contaminates are removed.
Note: Do not use solvents.
Note: Do not use grease on the sealing “O”-rings.
7. Reassemble hand tight and then using the two 19mm (3/4”) spanners tighten the
assembly by ¼ of a turn clockwise. Do not over-tighten the hexagonal nuts.
