1 Overview

1 Overview
1.1 About This ProductThis product is a control device that drives and controls the oxygen sensor in an oxygen analyzer thatuses a limiting current type zirconia oxygen sensor, and is responsible for concentration calculationand output. It is used in combination with our oxygen sensor (transmitter).
Since the oxygen sensor of this analyzer does not require pretreatment of the measurement gas, it issmaller and has a faster response speed than conventional sampling-type devices equipped with apretreatment device.
In addition, since calibration can be performed using only "instrumentation air" using compressed air,which is commonly found in factories and ships, there is the advantage of not needing to install ormanage standard gas cylinders.

3 Installation
This product is a device that controls Oxygen Sensor and calculates and outputs concentration.
In order to measure the oxygen concentration, connect our company's zirconia Oxygen Sensor anduse it by constructing piping related parts. A typical system configuration example is shown below.

3.1 System Configuration Example
Note Confirm the delivery specifications for scope of delivery and actual system configuration.

3.1.1 System Configuration Example 1
This system is an example of using "TF-10 Probe Transmitter" as an oxygen sensor to measure theoxygen concentration in flue gas from a boiler, etc. Manually operated valves such as needle valve andball valve are used for calibration gas lines. At the time of calibration, after manually operating thevalve to supply the calibration gas, calibration is executed by key operation on the receiver.
Use instrument air or atmospheric gas for calibration. （Calibration using standard gas cylinders suchas zero gas and span gas is not required.）DTF-102 Receiver

3.1.3 System Configuration Example 3This system uses a TF-III type probe transmitter as an oxygen sensor, to measure the oxygen
concentration in high-temperature flue gas in a heating furnace. In addition to calibration gas piping,ejector air piping and purge air piping are used. Since the calibration gas and purge air are operated by
opening and closing the solenoid valve using the contact output of the receiver, calibration and purge
can be performed by methods such as "receiver key operation", "contact input", and "receiver internal
timer". Use instrument air gas for calibration. （Calibration using standard gas cylinders such as zerogas and span gas is not required.） The TF-III type probe transmitter uses a separate power supply
and temperature control device for heating and keeping warm in order to prevent dew condensation in
the sampling section.

The product number is indicated on the rating plate of the receiver. (The rating plate is pasted on theinside of the door.)

2. Check the input/output you are actually using
Check the terminal symbols that are actually wired to the terminal block of the DTF-101 receiver. Enterthe input/output items in the columns of "Used contact input items" and "Used contact output items" only
for the terminals that are wired. Even if contact input/output is set, there is no need to wire the replacement
receiver (DTF-102) because the terminals that are not actually wired are not used.

3. Check the input/output settings of the DTF-102 receiver
Check the contact input and contact output contents from the replacement receiver (DTF-102) productnumber (CAT NO.). Described in the "DTF-102 contact input setting" and "DTF-102 contact output
setting" columns.

4. Relocate the wiring to the corresponding terminal on the DTF-102
receiverMove the wiring to the terminals of the DTF-102 receiver that have the same items as the "contact input
items in use" and "contact output items in use".

5 Calibration
5.1 About Calibration
In order to correctly measure oxygen concentration, perform gas calibration using the reference gas(hereinafter referred to as calibration) in following cases.
 When using analyzer for the first time.
 After replacing the oxygen sensor.
 Periodic inspections.
Recommended calibration cycle
Air-Point Calibration：1/month

Remarks

 Warm up sufficiently before Calibration.
Warm-up time as a guide：Approx. 2 hours

5.2 Calibration Point and Calibration Type5.2.1 Calibration Point Type
Oxygen analyzers using our limiting current type zirconia oxygen sensor can perform measurement
only by calibrating the air point.
Normally, it is used for 1-Point Calibration with the calibration point as the air point.
For the air point, use "instrument air", "atmosphere", or "standard gas with atmospheric equivalentconcentration".
Other calibrations are performed to further improve accuracy for specific gas concentrations, or whenaccuracy confirmation and calibration using standard gases are required.

6 Purging
6.1 About Purging
Purging is the process of blowing compressed air to remove dust and other foreign matter (hereafterreferred to as dust) that has entered or deposited in the measurement gas flow path around the oxygen
sensor or inside the sampling probe.
If dust is contained in the sample gas, purge as necessary to reduce dust accumulation and clogging.
In addition, continuous purging prevents dust from entering the measurement gas flow path, so it ispossible to protect the oxygen sensor and measurement gas flow path during periods whenmeasurements are not performed.
This product can configure a system that performs semi-automatic or automatic purging by opening
and closing the solenoid valve installed in the flow path of compressed air for purging with contact
output.

6.2 Purge Method Type
This product can purge by the following two methods.
When changing the purge method, it is necessary to change the CH data setting.
Normally, we set the purge method according to the customer's usage at the time of shipment.

7.4 Sleep Mode
7.4.1 About Sleep Mode
Sleep mode is a function that protects the oxygen sensor and measurement gas flow path fromexhaust gases by continuously supplying purge air while the oxygen sensor is not driven.
There are cases that non-driving oxygen sensor, measurement gas flow path and transmitter are
exposed to exhaust gas and residual gas in the furnace, when combustion equipment is stopped for along period of time due to installation, test, inspection or repair. While the sensor is in driving, thezirconia oxygen sensor is durable against dirty gases such as exhaust gas. However, when the sensor
is not driven (low temperature), If exposed to dirty gas such as exhaust gas or residual gas in the
furnace, the sensor will deteriorate in a short period of time and may not be able to measure. In
addition, dust accumulation and clogging may occur in the sample gas flow path.
In sleep mode, the oxygen sensor is not driven, and purge air is continuously supplied to protect theoxygen sensor and measurement gas flow path from exhaust gas.
When performing continuous purging automatically using the sleep mode, a system is required tooperate the solenoid valve as shown in "3.1.2 System Configuration Example 2" or "3.1.3 System
Configuration Example 3".

9.2.1 Oxygen Sensor Failed
If "E-05" or "E-07" occurs during using (after a normal measurement period), the oxygen sensor may
have failed due to its life. Follow the steps below to check the cause and restore the analyzer.
"E-05" or "E-07" occur
When the error occurred ?

Immediately after installation,
after sensor replacement, after wiring work.

During use

No abnormalities
No recovery[Check heater resistance]
Remove the signal line of the oxygen sensor
from the receiver, cool the sensor to room
temperature, and check the resistance between"H+" and "H-".

[Check the wiring connection]
Check if there is a connection failure orcontinuity failure between the oxygen sensor
and the receiver.
e.g.) - Wrong connection, disconnection,looseness of wiring- Deterioration and damage of cables[Check the wiring connection]
2 to 5Ω

Check if there is a connection failure orcontinuity failure between the oxygen sensor
and the receiver.
e.g.) - Wrong connection, disconnection,looseness of wiring- Deterioration and damage of cables
No abnormalities
No recovery

10Ω or more
Cause：Oxygen sensor life failure→ Replacement the oxygen sensor

Please contact us or our agency.

Fig. 9-1 Confirmation Procedure When Occurred “E-05” and “E-07”

Note If receiver detecting multiple errors at the same time, pressing
key once will display
another error code. Press
key multiple times until the Temp. rising state is temporarily
entered, and check for recurrence of the error.
 Timing of occurrence- During use and sensor usage time is long (1 year or more)：→High possibility of oxygen sensor life failure.
- During use and sensor usage time is short：→Check the setting data in CH No.190,192,193.
- After installation, replacement the sensor, maintenance：→High possibility of poor contacts or incorrect connection.
 If the resistance value between "H+" and "H-" is 5Ω < R <10Ω, cool the sensor sufficiently
and then check again.
