CHECKLIST

A typical IMPS 4000 should contain the items shown in Figure 1-1. Record

the part number, serial number, and order number for the IMPS 4000 on the

back cover of this manual.

Figure 1-1. Typical System Package

1. Instruction Manual

2. IMPS 4000

SYSTEM OVERVIEW

Physical Description The main components of the IMPS 4000 are housed in a NEMA 4X (IP56)

enclosure for use in non-hazardous areas.

The main internal components include the flow panel and the inner assembly.

Flow Panel (Figure 1-2)

The Programmable Logic Controller (PLC) operator interface and the

reference and test gas flowmeters are mounted to the flow panel.

1. The PLC operator interface allows you to set up time-sequenced

calibration routines for up to four oxygen transmitters. It also allows you

to initiate a semi-automatic calibration.

2. Four sets of test gas and reference gas flowmeters are mounted on the

flow panel. One set of flowmeters is available for each of the four

oxygen transmitters that can be attached to the IMPS 4000. The test

gas flowmeter indicates the amount of test gas sent to the oxygen

transmitter. The reference gas flowmeter indicates the amount of

reference air flowing to the oxygen transmitter.

Figure 1-2. IMPS Components

Inner Assembly

The inner assembly consists of the PLC, PC board, pressure regulator, gas

solenoids, test gas pressure switches, and heater.

1. The PLC consists of a power supply, Central Processing Unit (CPU),

and three I/O modules.

a. The power supply supplies the voltage and current needed to

operate the IMPS 4000.

b. The CPU controls most system operations. It contains the program

memory in which the information entered into the PLC operator

interface is stored, and it processes the I/O signals received from the

I/O modules.

c. The I/O modules are terminated on the PC board. They receive and

send signals between the PLC and PC board for communication

between the oxygen transmitter and the IMPS 4000.

2. The PC board contains all wiring connections for up to four oxygen

transmitters.

3. The pressure regulator ensures the instrument air (reference gas)

flowing to the oxygen transmitter is at a constant pressure. The

regulator also has a drain valve that drains excess moisture from the

internal gas circuit.

4. The manifold can have up to six solenoids: test gas 1 solenoid, test gas

2 solenoid, and a gas solenoid for each oxygen transmitter connected to

the IMPS 4000. The solenoids activate and deactivate to allow test gas

to flow between the IMPS 4000 and an oxygen transmitter.

IM-106-400 IMPS, Rev. 3

July 2016

4000 IMPS

5. The pressure switches detect if the pressure of a test gas is low, which

can be caused by an empty gas bottle, a disconnected gas line, etc.

Calibration is prohibited when test gas pressure is low.

6. The heater keeps the components in the ambient temperature range to

prevent electronic malfunction.

THEORY OF OPERATION Reference Figure 1-3. When a calibration is initiated, via the IMPS,

HART/AMS, oxygen transmitter, or remote location, the signal is sent to the

IMPS 4000 PLC. The PLC first energizes the oxygen transmitter solenoid and

then energizes the test gas 1 (high gas) solenoid. Test gas 1 flows through the

IMPS 4000 to the oxygen transmitter. The oxygen transmitter measures the

oxygen content of test gas 1 and sends a signal to the IMPS 4000 indicating

that it received test gas 1. When the IMPS 4000 receives the signal, the PLC

deenergizes the test gas 1 solenoid.

Figure 1-3. IMPS Calibration Setup

1-5

Instruction Manual

IM-106-400 IMPS, Rev. 3

July 2016

4000 IMPS

After a time delay that allows test gas 1 to clear the system, the PLC

energizes the test gas 2 (low gas) solenoid. Test gas 2 flows through the

IMPS 4000 to the oxygen transmitter. The oxygen transmitter measures the

oxygen content of test gas 2 and sends a signal to the IMPS 4000 indicating

that it received test gas 2. After measuring the two test gases, the oxygen

transmitter automatically makes the internal calibration adjustment and sends

the signal to the IMPS 4000. When the IMPS receives the signal, the PLC

deenergizes the test gas 2 solenoid and the oxygen transmitter solenoid.

Whether or not the calibration passes or fails displays on the PLC operator

interface.

Z-PURGE OPTION Some IMPS applications have area safety requirements (Class 1, Division 2).

These requirements may be satisfied with the installation of an optional

Z-purge. The Z-Purge provides positive pressure within the IMPS 4000

enclosure to keep out dust and other foreign matter. Figure 1-4 shows the

Z-purge unit and how it connects to the IMPS 4000.

valve is set at the factory to 20 psi (138 kPa). If necessary, readjust by

turning the knob on the top of the valve until the desired pressure is

obtained.

2. Connect the O

2

test gas 1 to HIGH CAL GAS IN. The test gas pressure

should be set at 20 psi (138 kPa).

3. Connect the O

2

test gas 1 to LOW CAL GAS IN. The test gas pressure

should be set at 20 psi (138 kPa).

4. Connect the oxygen transmitter REF GAS to REF AIR OUT.

5. Connect the oxygen transmitter CAL GAS to TEST GAS OUT.

ELECTRICAL

CONNECTIONS

All wiring must conform to local and national codes. Refer to Figure 2-3 and

use the following procedure to connect the first oxygen transmitter. Repeat

the procedure for each remaining oxygen transmitter.

1. Run the line voltage through the bulkhead fitting on the bottom of the

IMPS 4000 marked LINE IN. Connect the line voltage to the J24

terminal. The power supply automatically adjusts to the input voltage.

Tighten the cord grips to provide strain relief.

2. When connecting an Oxymitter O

2

Transmitter, run the handshake logic

I/O wires for each oxygen transmitter through a bulkhead fitting on the

bottom of the IMPS 4000 marked SIGNAL IN. Dedicate one fitting for

each oxygen transmitter. Connect the oxygen transmitter logic I/O wires

as shown in Figure 2-3.

3. When connecting an XI or 6888XI electronics, run the handshake

signal wires from connector J3 of the Xi or 6888Xi I/O board through

a bulkhead fitting on the bottom of the IMPS 4000 marked SIGNAL

IN. Dedicate one fitting for each oxygen transmitter. Connect the

oxygen transmitter handshake signal wires as shown in Figure 2-3.

4. To set up the IMPS 4000 to initiate a calibration from a remote location,

run the remote contact input wires through the SIGNAL IN bulkhead

fitting. Connect the remote contact input wires as shown in Figure 2-3.

5. Status relay connections are available on the IMPS 4000 PC board to

signal when the oxygen transmitter is in or out of calibration and to

indicate calibration gas status. Status relays can be connected to either

indicator lights or a computer interface. Relay contacts are capable of

handling up to 5 to 30 V, 1.5 A per point, 3.0 A total per common

maximum power source. Cabling requirement is 1000 ft (303 m)

maximum. Make the status relay switch connections as shown in

Figure 2-3.

OVERVIEW This section specifies the requirements to set up an oxygen transmitter

calibration. It describes the PLC operator interface and explains how to set up

time-sequenced calibration routines for up to four oxygen transmitters using

the IMPS 4000. This section also explains the differences between automatic

and semi-automatic calibrations and how to initiate them.

CALIBRATION

REQUIREMENTS

The following components are required for an oxygen transmitter calibration

using the IMPS 4000:

1. Two tanks of precision calibration gas mixtures are required.

Recommended calibration gases are nominally 0.4% and 8.0% oxygen

in nitrogen. Two sources of calibrated gas mixtures are:

2. A check valve is required at the oxygen transmitter (between the

calibration fitting and the gas line) to prevent the migration of process

gases down the calibration gas line. A typical calibration setup is shown

in Section 1, Figure 1-3 of this manual.

OPERATOR INTERFACE

DESCRIPTION

See Figure 3-1. The operator interface consists of a membrane keypad and a

4-line, 16-character, backlit LCD display. The LCD display is divided into two

areas. The left side is a descriptive field that identifies the calibration

parameter. The right side shows the current value or status of the calibration

parameter.
