9.5. Setting for operation
9.5.1. PROGRAM MODE
9.3. Test Mode
■ If there is no abnormality in SELF TEST after Power On, the following gas measuring state is automatically entered into.
- When "▲", "▼" keys are simultaneously pushed in the display state for gas concentration, the setting
function for program data is entered into.
- In the program setting function, the display state for gas concentration is automatically returned to
when 10 sec passed after the last key operation in the program setting function.
- The message for setting of decimal point as the 1st function of setting function for program data is
displayed as "dP-S".
- When "Func" key is pushed, the setting function for decimal point is entered into.
- When "Reset" key is pushed, the concentration display mode is returned to.
- Decimal point is used when there is a need to change according to measuring range. When position
of the decimal point is set, the position of the decimal point is changed in 3 ways as shown on the left
whenever "▲" key or "▼" key is pushed.
- If "FUNC" key is pushed when the desired position of decimal point is displayed, the decimal point
position is set and the next item is entered into.
- When "Reset" key is pushed, the concentration display mode is returned to.
- The message for setting function of High scale as a function for setting the maximum value of gas
concentration display is displayed as "H-SL".
- When "Func" key is pushed, the setting function for High scale is entered into.
- When "Reset" key is pushed, the concentration display mode is returned to.
- High scale value is set for the range specified by domestic regulations upon product shipment.
- The setting value for High scale can be changed according to measuring range, and the Scale value
is increased or decreased whenever "▲" key or "▼" key is pushed.
- If "FUNC" key is pushed when the desired High scale value is displayed, the High scale value is set,
and the next item is entered into.
- When "Reset" key is pushed, the concentration display mode is returned to.
- The present setting mode shall be set for the same measuring range as the detection unit upon
factory shipment. Ex) When Range setting was made to be 100
Upon inputting of 4 mA.DC ................... 0 Display
Upon inputting of 20 mA. DC ................... 100 Display
- When "Test" key is pushed for more than 2sec in the display state of gas concentration, Test mode
is entered into.
- When 30 min is passed after the last key operation in Test mode, the display state of gas concentration
is automatically entered into.
- Upon entering in Test mode, the displayed figure for gas concentration is displayed by blinking,
where this function allows test in Channel unit without injection of sensor gas in the detector. When
the user pushes "▲" key or "▼" key , an arbitrary concentration value for gas concentration can be
set, while Alarm function is normally operated with the concentration value designated by sec, FND/
LED/Bar LED test function is entered into.
- When "Reset" key is pushed, the concentration display mode is returned to.
- FND/LED/Bar LED Test mode where FND figure of 4 digits and the entire display (8888) are displayed
at an interval of 0.5sec, with the 4-digit figure displaying the setting values for PC Add(SW1) and CH
CNT(SW2) of Common unit.
- 3 Color bar graphic LED displays green, orange and red colors alternatingly at an interval of 0.5sec
with each function LED blinking at an interval of 0.5sec.
- When "Func" key is pushed, the mode for checking Channel unit with normal operation of Common
unit and communication is entered into.
- When "Reset" key is pushed, the concentration display mode is returned to.
- Mode for checking of Channel unit with normal operation of Common unit and communication,
where the No. of channel unit with normal communication being realized is sequentially displayed at
an interval of 0.5sec .
- If there is a No. for Channel unit where all of the number of channel units set in common unit is not
displayed but omitted, then it becomes the channel unit without communication.
- When "Func" key is pushed, Test function for gas concentration is returned to.
- When "Reset" key is pushed, the concentration display mode is returned to.
9.4. Checkup mode (Stand-by Mode)
- When "▼(Standby)" key of channel unit is pushed for more than 2sec in the display state for gas
concentration, checkup mode is entered into.
- In the checkup mode, the checkup mode is cleared and the display state for gas concentration is
returned to when"▼(Standby)" key is surely pushed in channel unit,
- The function where STD-BY LED blinks inn checkup mode, and contact output of Trouble/Alarm
relay for Common unit and Channel unit의 Trouble/Alarm relay does not operate with all remaining
functions in operation.
- When "▼(Standby)" is pushed, the concentration display mode is returned to.
