３－４ Inspection after installation!

Proper wiring from the transmitter of Zirconia type O2 analyzer to the receiver ofModel 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 forthe 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 check（CELL+, CELL-）
Disconnect the lead lines of（CELL+）,(CELL-） at the terminal block of the receiver,And measure the resistance between the lines.
Room temperature : ∞ΩNote: The thermocouple lines (TC+)/(TC-) and cell lines (CELL+)/(CELL-) polarities.
During/after the temperature rise, verify that the thermocouple generates the properelectromotive 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 zerogas 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 thetransmitter 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 calculationis possible. (63% response Here, 90% response conversion isfunction
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 duringcalibration, 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 andAlarm 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 withthe 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.
Remote range switch function

Two kinds of the ranges can be switched from the external byturning on and off no-voltage contact input of the terminal.

Remote calibration start
function

The automatic calibration can be started by turning on the novoltage contact input of the terminal.

MFT signal input processfunction

The heater control of the detector is turned off by the main fueltrip (MFT) signal (the error is not output), and the purge relay
is turned on. After MFT is reset, it is started at the temperaturerise.

After the input is reset, the process starts at temperature rise.
Shorting this terminal restarts the timer for timer calibration and timer
