1Introduction
1.1 Scope and definitions
This manual provides installation, operation and maintenance instructions for the Edwards exhaust temperature
transmitter accessory. The temperature transmitter must be used as specified in this manual. Read this manual
before installing and operating the temperature transmitter.
Important safety information is highlighted as WARNING and CAUTION instructions; these instructions must be
obeyed. The use of WARNINGS and CAUTIONS is defined below.
CAUTION
Cautions are given where failure to observe the instruction could result in damage to the equipment, associated
equipment and process.
1.2 Description
1.2.1 Operational information
The CXS Exhaust temperature transmitter accessory comprises an Endress and Hauser Ex ia temperature transmitter
and a kit of parts to enable connection to the CXS dry pump. Once connected and set-up, it is possible to display
exhaust gas temperatures on a Pump Display Terminal (PDT). Alternatively, the temperature transmitter can be
connected directly to an independent control system using suitable wiring and intrinsic safety barriers (not supplied)
suitable for the instrument and environment.
The PDT (part number D372-80-700) is available as an accessory and must be used for installation configuration.
Pack contents:
Temperature transmitter TR10-GBA8CDR2H200E
Cable M52809281
Gland RS 444-2931 REF 5311 1510
Gland locknut LAPP 53119013
Tie wraps (not shown) KAT. C. 460194
Edwards instruction manual M52800840
Endress and Hauser TR10 instruction manual
WARNING
Warnings are given where failure to observe the instruction could result in injury or death to
people.

Installation

2 Installation
2.1 Installation safety
2.2 Exhaust temperature transmitter installation
For connection to the control system of the CXS dry pump, follow all steps. If the temperature transmitter is to be
connected to an independent control system, only the mechanical installation steps should be followed and steps 6-
14 should be ignored.
If the pump has previously been run on process, perform the following steps:
1. Allow the pump system to cool to a safe temperature before starting maintenance work.
2. Vent and purge the dry pumping system before starting any installation or maintenance work.
3. Isolate the dry pumping system and other components in the process system from the electrical supply to
prevent accidental operation.
Note: The emergency stop switch on the dry pumping system is not an electrical isolator.
WARNING
The exhaust should only be opened when the pump is switched off, isolated from the electrical
supply and in the absence of explosive atmosphere.
WARNING
The surfaces of the inlet can be very hot when the CXS system is running. Surfaces should be
allowed to cool to a safe temperature before installing the pressure transmitter.
WARNING
Ensure that the pump is purged and isolate the inlet and exhaust before installation or
replacement.
WARNING
Leak test the system after installation and seal leaks to prevent leakage of dangerous substances
out and leakage of air into the system.
WARNING
Use appropriate personal protective equipment.
Personal protective equipment should be checked and used as specified by the supplier. Hazardous
chemicals that have been pumped are located within the pumps and piping. Edwards recommends
the use of suitable protective gloves and clothing along with a respirator if contact with substances
is anticipated. Particular caution should be exercised when working with fluorinated materials
which may have been exposed to temperatures greater than 260°C. Refer to Edwards Material
Safety Data Sheets for detailed information.

Installation
Figure 3 - Exhaust and plug location
4. Remove the plug from the exhaust assembly.
5. Coat the thread of the transmitter with Loctite®577 thread sealant or equivalent suitable for the process. Insert
into the exhaust port pipe and secure with the correct size spanners, ensuring a gas tight seal.
6. Plug the temperature transmitter loom into position 8 (default) or 2 (Refer to Figure 5) depending on which
connection is required (See Section 2.3).
7. Attach the cable gland and its associated lock-nut (Figure 1, items 2 and 3) to the frame as shown in Figure 2.
8. Route the cable as shown in Figure 2 and pass through the gland.
9. Loosely position the cable to the attach points with tie wraps.
10. Ensure the cable glands are fitted but remain loose on the frame and the PT100 temperature transmitter.
11. Continue to route the cable and push through the gland into the PT100 temperature transmitter.
12. Using the minimum bend possible, route the cable into the top of the temperature transmitter as shown in
Figure 4 and secure to terminals 1 (+ve) and 2 (-ve) when plugged into position 8.
Note: If the transmitter is plugged into connection 2 (Figure 5) then the connections to terminals 1 and 2
(Figure 4) must be reversed.
13. Tighten the glands and tie wraps. The tie wraps should be trimmed ensuring no sharp edges protrude.
14. Test the unit according to the instructions in this manual.

Installation
2.3 Exhaust temperature transmitter set-up
CAUTION
Configuration changes made using the PDT should be performed with the pump not running. It is recommended
that the CXS dry pump is then power-cycled following configuration changes.
The Pump Display Terminal (PDT) must be used to configure the exhaust temperature transmitter. The PDT must be
connected and used in accordance with the instructions in the CXS instruction manual M528-00-880.
Figure 6 - Pump Display Terminal (PDT)
The PDT should be plugged in and the pump switched on. When the PDT is powered up, select and set the transmitter
accessory options as follows:
1. Press 'setup' - scroll using arrow keys to 'Service'.
2. Scroll to 'fit accessory'.
3. If loom is connected to ' Bulkhead Connector 8' then scroll to transmitter (PT100 1) and select 'fitted' using arrow
keys and press 'enter'.
4. If loom is connected to 'Bulkhead Connector 2' then scroll to transmitter PT100 2 and select 'fitted' using arrow
keys and press 'enter'.
5. To exit the menu press the 'cancel' key three times where the indicator lights will revert to the initial menu.
WARNING
The PDT is a non-Ex device, suitable for use in a hazardous area. It must be connected using a
suitable cable according to EN60079-14 and routed into the safe area.
WARNING
The test/diagnostics port on the Ex d control box door is intended for connection to a PDT for
commissioning, service and diagnostic purposes, only when:
- the CXS dry pump is installed in a safe area, or if safety within the hazardous area can be
guaranteed, for example by the use of a suitable gas detector to ensure the absence of any
explosive atmosphere.
After the PDT socket has been used, the explosion-proof stopping-plug must be refitted. Check the
condition of the threads and O-ring, tighten hand-tight then a further half turn with a wrench.
Incorrect use of the PDT socket and PDT will invalidate the explosion-proof rating of the CXS dry
pump and may result in an explosion in the hazardous area.

Return the equipment or components for service
Before you send your equipment to us for service or for any other reason, you must send us a
completed Declaration of Contamination of Vacuum Equipment and Components – Form HS2. The
HS2 form tells us if any substances found in the equipment are hazardous, which is important for
the safety of our employees and all other people involved in the service of your equipment. The
hazard information also lets us select the correct procedures to service your equipment.
We provide instructions for completing the form in the Declaration of Contamination of Vacuum
equipment and Components – Procedure HS1.
If you are returning a vacuum pump, note the following:
 If a pump is configured to suit the application, make a record of the configuration before
returning the pump. All replacement pumps will be supplied with default factory settings.
 Do not return a pump with accessories fitted. Remove all accessories and retain them for
future use.
 The instruction in the returns procedure to drain all fluids does not apply to the lubricant in
pump oil reservoirs.
Download the latest documents from www.edwardsvacuum.com/HSForms/, follow the procedure in
HS1, fill in the electronic HS2 form, print it, sign it, and return the signed copy to Edwards.
Note: If we do not receive a completed HS2 form, we will not accept the return of the
equipment.
