! Cautionary points as to installation
Since the analyzer is a precise instrument, take care to prevent applying
excessive shock or load during installation.
Since it is easily damaged, take care not to hit the instrument during
installation.
Wiring method Connect the wiring at the terminal block. Route the cables
through the wiring hole at the bottom of the case. Moreover, apply a dust-
tight and drip-proof seal to the wiring during installation.

Inspection after installation
! Proper wiring from the transmitter of Zirconia type O2 analyzer to the
receiver of
Model DGO-101 receiver. If power is supplied to the wrong wiring, it will
cause a Sensor breakage or other serious trouble. In order to prevent trouble
which results from wrong wiring, check the wiring by the following Procedure
with the air selected as the measured gas when turning on the power supply for
the first time for test operation and adjustment. After verifying that the
power supply of the receiver is off, check the following. (1)Heater wiring
check (HEATER) Disconnect the lead lines of (HEATER “2 terminal”) at the
terminal block of the receiver, and measure the resistance between the lines.
(2) Thermocouple wiring check (TC+) (TC-) Disconnect the lead lines of
(TC+),(TC-)(HEATER) at the terminal block of the receiver, and measure the
resistance between the lines. For the reference values, refer to the
instruction manual of the transmitter used. Take sufficient care to prevent
the disconnected line from being short-circuited or
!
grounded. (3) Cell wiring checkCELL+, CELL-
Disconnect the lead lines ofCELL+,(CELL- at the terminal block of the
receiver, And measure the resistance between the lines. Room temperature :
Note: The thermocouple lines (TC+)/(TC-) and cell lines (CELL+)/(CELL-)
polarities. During/after the temperature rise, verify that the thermocouple
generates the proper electromotive force. If the +/- polarities are reversed,
the error E-06 will be displayed. Moreover, it is correct if any electromotive
force and value are displayed when the zero gas is flowed. (If the polarities
+/- are reversed, the E-12 error will be displayed.) (4) After the wiring is
completely checked, attach the marking bands to the cables of the
transmitter and receiver as it will simplify the wiring check during
maintenance, inspection and sensor replacement.

Description
Automatic calibration function
The solenoid valve is automatically opened and closed every preset time to
apply the air, zero and span calibration. Note 1) There are two methods:
automatic calibration is started
Every time preset by the timer and at a desired time by key operation Note 2)
The calibration types of one-point calibration with the Air and three-point
calibration with air, zero and span Can be selected.
The primary delay calculation in the range of 0 through 60 seconds Primary
delay calculation
is possible. (63% response Here, 90% response conversion is function
multiplied 2.3 times.)
O2 upper/lower limit alarm function
The alarm contact is output by setting the upper and lower limit Values of O2. Note) The alarm contact is automatically reset.
Output holding function
When the sensor is abnormal, the output value can be held during calibration,
purging and MFT input. Note) Kinds of holds
STD : The value measured 5 seconds before the phenomenon Occurs is output.
OFF : During calibration/purging, the measured value is output. When another
phenomenon occurs, the value measured 5 seconds Before the phenomenon occurs
is output.
PHM1: The set value of 0 to 100% FS is output. PHM2: The set value of 0 to
100% FS is output.
Self-diagnosis function
The abnormal places of the sensor and receiver are automatically Detected with the self-diagnosis, and the error indication and Alarm contact are output.
Monitor function
The O2 value, cell electromotive force, thermocouple electromotive force and other data can be monitored.
Output value check /adjustment function
The output value of 4 to 20 mA can be checked and adjusted with the key operation.
A desired value can be set for the SPAN point and ZERO point of
the measured range.
Note1) Two kinds of the Hi/Lo ranges can be set. Programmable range function
Note2) The ranges of min. 5%O2 to max. 25%O2 is applied. The
Width of the range which does not include 0% is set at
10%O2 or more.
Two kinds of the ranges can be switched from the external by Remote range switch function turning on and off no-voltage contact input of the terminal.
Remote calibration start The automatic calibration can be started by turning on the no-
function
voltage contact input of the terminal.
MFT signal input process function
The heater control of the detector is turned off by the main fuel trip (MFT) signal (the error is not output), and the purge relay is turned on. After MFT is reset, it is started at the temperature rise.

Start-up Operation The basic operation procedure for starting the oxygen
analyzer is shown below.
Start-up operation
Turn the power ON. LED display
RANGE(H)O2vol% (Measurement starts.)
Turn the power ON. After the external power switch and the power switch inside the receiver are turned on, the receiver starts the countdown timer for warming the sensor (WARM-UP shown on LCD). After the set temperature has been reached, the measurement mode starts.
Check the output range. Check the range (H/L) using the MODE key.
LED display DISPLAY SELECT
Operating the key on the receiver, check the output signal range. To change the range, refer to page 19.

Stopping Operation
Stopping Operation
Before turning the receiver off, check that the inside of
! the transmitter and the sensor are in the air environment.
Otherwise sensor deterioration will result.
Turn the power OFF.
Turn the power switch of the receiver off.
When inspecting the terminals of the analyzer or receiver or performing
maintenance work accompanying
! disconnection of wiring, turn the external power
switch (source power switch) off.

Automatic tuning operation method Transmitter sensor temperature is controlled by PID control.
This receiver is compatible with various transmitter, so the PID value differs.
Therefore, depending on the transmitter, the temperature may not be stable. In that case,
perform the auto tuning by the following. Set DIP switch S2 No.1 to ON
Up key
Since this operation is the setting of the system key, perform the operation shown on the left. Open the control panel and remove the Insulation sheet. There is a S2 on the CPU board.

Method
According to item 5-6, apply the gas calibration. (According to item 5-3(4), set the calibration method and so on.)
Interval One month
Sensor inspection
Method
After the gas calibration is completed check the drift value against the previously calibrated value. (CAL, DATAMONITOR) though it is normally +/-2% F.S./month or less, the sensor may be liable to age if the value is exceeded.
1 to 6 months (Check if any abnormally is found during Interval
gas calibration.)
Method
Check EMF electromotive force at the AIR, ZERO and SPAN points (DISPLAY SELECT) Check the response time which results from the calibration gas switch
For inspection of the sensor, refer to the instruction manual of the transmitter.
