Terminal Wiring Diagram

• Connect AC power (100 – 250 V, 50/60 ㎐) to the power as shown in the figure.
• Turn on the power switch and turn on the battery switch.

How to Operate

Power Input

• When the power switch is turned on, all lamps are turned on (for 1 second), the POWER lamp is turned on, and the STD-BY lamp blinks.
• And after the buzzer sounds once and information is displayed, the initial delay (30 seconds) is sequentially counted down (29, 28, 27…).
• If the 2.5 – 4.0 mA input (for 3 seconds) of the detector is not detected during countdown, Err1 is displayed and an alarm (continuous sound) is generated.
• When the countdown is normally completed, the concentration according to the detector input signal (4 – 20 mA) is displayed.

BATT CHECK

• When the BATT CHECK lamp blinks, turn on the battery switch of the terminal.
• If the battery is not detected, the BATT CHECK lamp continues to blink.
• If the battery is detected but the battery level is less than 30%, the lamp blinks.
• When the battery is charging, the blinking lamp turns off when it is detected that the battery level is over 30%.
• If there is a problem with the battery, the alarm does not occur.
• Press the BATT CHECK button to display the battery status.
• (If pressed for more than 5 seconds, the LED function stops, and if pressed again for more than 5 seconds, it operates again.)
• ( In case of battery failure: Displays “Err”, in case of charging or being fully charged: Displays available time by minute)
• When using AC power: Displays the battery level as a percentage (0-100%),
• When using DC power: Displays the available time in minutes

| A defect was detected in the battery.
---|---
| Battery level is less than 30%.
| The battery is currently available for 120 minutes.
| The battery is currently available for 65 minutes.
| The battery charge is 85%.
| The battery charge is 60%.

• Battery in use: LED on
• Battery error: LED blinking

B/Z STOP

• During gas detection, an alarm (—) is generated when the concentration exceeds the set alarm value (1st, 2nd, 3rd) due to a change in concentration.
• (Alarm sounds change rapidly in the first, second, and third tones.)
• If you operate the B/Z STOP switch after the alarm occurs, the alarm stops and the B/Z STOP lamp blinks (For all alarms).
• If you operate the button again after stopping the buzzer, the alarm will be generated again (The lamp will turn off).
• If the gas concentration is less than the first alarm value, the lamp turns on.

RESET

• If the alarm generated by the change of gas concentration during gas monitoring changes to less than the primary alarm value, it can be reset with the RESET button.
• At this time, the RESET lamp is lit when an alarm sounds and blinking reset is possible (At this time, the sound becomes slower than the 1st, 2nd, and 3rd alarms).
• When the RESET lamp changes from blinking to on, it is possible to reset. If you press the RESET button, the alarm stops and the lamp turns off (At this time, the alarm, 1st, 2nd, 3rd lamp, and B/Z STOP lamp are also turned off).

FAULT

• If the 4mA signal of the detector is not input, the FAULT lamp blinks and an alarm (continuous sound) is generated.
• (Integrated sensor type determines whether to blink the FAULT lamp with the sensor value.)

TEST S/W

• When you press the TEST button, the set range value (0.000 – 9999) is sequentially converted and displayed.
• If you press the button for more than 1 second, the range is sequentially converted from 0 – 100% and the time is set to 10 seconds (for all ranges).
• (At this time, all outputs and alarms the same as when gas is detected are generated.) (Press the button during sequential conversion to stop or start the change in concentration.)
• After sequential conversion up to max range, it automatically returns after 30 seconds and enters gas monitoring mode.
• All outputs: 1st, 2nd, and 3rd contacts, 4 – 20 mA, RS-485, buzzer, lamp

MODE

• If you press the MODE button briefly, AL-1, AL-2, AL-3, SPAN setting value, number of calibrations, and RS-485 ID (255) are displayed.
• (In the initial setting, the AL-1 setting value is displayed, and you can change it to AL-2, AL-3, SPAN, etc. by using the UP and DOWN buttons.)
• You can check the value set when the product is shipped or during use (The number of calibrations increases by 1 count only in the case of gas calibration).
• The number of calibrations can be reset with the INIT button. (After 30 seconds have elapsed or the RESET button is pressed, it returns to the monitoring mode.)

UP / DOWN

• If you press the UP button briefly, the peak value memorized after standby is displayed, and when you release the button, it enters the monitoring mode.
• If you press the DOWN button briefly, the lowest value is displayed, and when you release the button, it enters the monitoring mode.
• (The peak value is reset when you turn the power off and on or remove and insert the battery.)

• If the setting button is pressed for 3 seconds, “ofSt” is displayed, and if the setting button is pressed once more, the current concentration is displayed.
• If the current concentration is displayed differently from 0, press the setting button for 1 second, then “SEt” will blink and the current value will be adjusted to 0. When the setting is complete, it is displayed as “SPAn”.
• (Setting mode also displays the ± value of the concentration value. In measurement mode, ± value is hidden.)
• If you press the setting button once again while “SPAn” is displayed, the set calibration gas concentration is displayed as a number.
• If the memorized calibration gas concentration is different, use the UP and DOWN buttons to input the same number as the calibration gas concentration and press the setting button for 1 second, then “SEt” will blink on the screen and the concentration value will change.
• When the setting is completed, it is displayed as “ScAL”.
• When the calibration gas concentration change is completed, it is displayed as “ScAL”. In this state, if the setting button is pressed, the current concentration is displayed. (If the concentration is different from the value of the standard gas when the concentration is held after the standard gas is injected)
• When the setting button is pressed for 1 second, “Set” blinks on the screen, and when “SPAn” is displayed on the screen, it is calibrated to the set value.
• (When calibration is completed, it automatically exits from the setting mode to the monitoring mode and displays the calibrated concentration.)
  • The calibration value can be changed even when “Err” is displayed on the screen. (SPAn)
