Location A KGD-6-H2S is normally mounted low in the room on a wall or column one foot above the floor in a central area where air movement is generally good. Use the same spacing as for smoke detectors, 30-foot centers, 900 square feet per detector (465 sq. - Page 6 Kele KGD-6-H2S Operation Manual 4. There are two terminals for Power: 12 to 24 VAC or 12 to 32 VDC, with no polarity preference. 5. There are two terminals for the dry alarm relay contacts, again with no polarity preference. The alarm relay can switch up to 0.5 A 120 V, or 60 VA.

Page 8: Power Up
Power Up The KGD-6-H2S steps through an internal self-test cycle for the first 1 minute that it is powered. The unit will execute the test cycle any time power is dropped and reapplied (i.e. power failure). During the self-test cycle the unit will display the Firmware Version number and the gas type, then count down from 60 to 0 (if the display option is “on”) - Page 9 Kele KGD-6-H2S Operation Manual Figure 4-1 Board View Selecting Default Configuration – “dEF” To select the Default Configuration, in normal mode, push the Next button to get to “Con” or the Configuration menu. Then push the Enter button to enter the Con menu. The first selection is the “dEF” or Default setting. Push Enter. If it is already in Default configuration, there will be no action.

Page 10: Onboard Diagnostics
Onboard Diagnostics The KGD-6-H2S monitors all critical functions of the unit through software diagnostics that continuously test and verify unit operations. If a problem is found, the unit will switch to a fail-safe/error mode or trouble condition. In this error mode, the Alarm relay will be activated, the 4-20 mA current loop will go to 24 mA, the unit will display the error code, the green status indicator LED light will flash and the buzzer will chirp intermittently. -
Page 11: Sensor Poisons
If the error mode repeats frequently, check for continuous power and proper voltage. If power is not the problem and a unit has repeating error conditions, it may need to be returned to Kele for service, per these User Instructions. -

4. Remove the Shorting Spring from the new sensor and insert the new sensor into the socket. 5. Power up the unit. The KGD-6-H2S steps through an internal self-test cycle for the first 1 minute that it is powered. During the self-test cycle the unit will display the Firmware Version number, then count down from 60 to 0 and finally go into normal operation. -
Page 13: Operation Test
Setting Option is set to “ON”. Operation Test Check that the green KGD-6-H2S status indicator LED light is illuminated continuously. If not, do not proceed with the tests. If the unit is in error mode contact your local representative or Kele technical service representative for information on resolving the problem. - Page 14 5. Turn on the regulator to start the gas flow and wait with the gas applied continuously. 6. With the display function turned “On”, the KGD-6-H2S will show the current concentration of gas or “0” (zero) in clean air. When the gas concentration reaches the Fan Relay setting (8 ppm, for example) the display will flash back and forth between “FAn”...

Page 15: Field Calibration Procedure
Detector has 4-20 mA option set to “OFF”. Set 4-20mA option to “On” and repeat the test. 7. Remove the gas from the sensor. Re-assemble the KGD-6-H2S (make sure the LED is aligned with the front case hole). 4-20 current loop test is complete. - Page 16 Normal Mode. Calibration 1. Remove the Philips screw on the front of the KGD-6-H2S. Pull the front cover of the unit off. 2. Assemble the 25 ppm gas cylinder and regulator together. 3. Check the pressure gauge on the regulator. If you have 25-psi or less you will need to replace the gas canister.
