NH3 concentrations in industrial refrigeration, warehouses, hockey rinks or other commercial applications. The KGD-6-AM is a low level meter capable of displaying from 0-100 ppm of Ammonia. The KGD- 6-AM is factory calibrated and 100% tested for proper operation, but can also be calibrated in the field. -
Page 5: Use Instructions And Limitations
The KGD-6-AM is not intended for use in hazardous locations. Do not mount the KGD-6-AM where the normal ambient temperature is below 0°F or exceeds 125°F (below -18°C or above 52°C). The KGD-6-AM mounts on a 4x4 electrical box supplied by the contractor. -

Ammonia, actuate relays and provide a 4-20mA output. The KGD-6-AM has a field replaceable, electrochemical sensor (expected life of 2+ years) and optional gas test and calibration kits. The KGD- 6-AM is a low level meter capable of displaying from 0-100ppm of Ammonia. -
Page 7: Installation And Operating Instructions
Location A KGD-6-AM is normally mounted high in the room on a wall or column one foot below the ceiling 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. meters). The coverage depends on air movement within the room or facility. -
Page 8: Installation
Connect the KGD-6-AM to Class 2 power supply only. It is suggested to use a separate transformer for powering the unit or units because of possible interferences from other devices on the same power supply. - Page 9 Kele KGD-6-AM Operation Manual Figure 3-2 6-Series Rear View Figure 3-6 6-Series Stand Alone Diagram P a g e...

Page 12: Power Up
Power Up The KGD-6-AM 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”) and finally go into normal operation. - Page 13 The default Trouble Fan Setting condition is OFF ● The default 4-20mA Output setting is On To change settings, remove the Philips screw on the front of the KGD-6-AM. Pull off the front cover of the unit. Figure 4-1 Board View 13 |...

Page 16: Onboard Diagnostics
Onboard Diagnostics The KGD-6-AM 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. -

2-3 year expected life. The silence function will continue to be available for 29 days after the KGD-6-AM initiates the initial end-of-warranty signal. After this 29 day period the KGD-6-AM can no longer be silenced and the sensor must be replaced or the sensor life reset. -
Page 18: Sensor Life Reset
Sensor Life Reset Remove the Philips screw on the front of the KGD-6-AM. Pull the front cover of the unit off. To reset the sensor life (rSt), from normal or warm-up mode, press the Next button four times to get to SEn or Sensor Mode. -
Page 19: Testing
Operation Test Check that the green KGD-6-AM 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 20: Ammonia Test
● Ensure sensor inlets are unobstructed and is free of debris General The KGD-6-AM can be bump-tested or calibrated with the AM-FCK with Ammonia gas, regulator and test hood, available through your local representative or from Kele. 20 | P a g e... - Page 21 Gas Testing Testing the Fan Relay – Remove the Philips screw on the front of the KGD-6-AM. Remove the front cover. Open the FCK. Connect the 25 ppm gas cylinder to the regulator. Check the pressure gauge on the regulator. If you have 25-psi or less you will need to replace the gas canister.
- Page 22 Turn on the regulator to start the gas flow and wait with the gas applied continuously. With the display function turned “On”, the KGD-6-AM will show the current concentration of gas or “0” (zero) in clean air. When the gas concentration reaches the Fan Relay setting (20 ppm, for example) the display will flash back and forth between “FAn” and “20”.

Detector has 4-20 mA option set to “OFF”. Set 4-20mA option to “On” and repeat the test. Remove the gas from the sensor. Re-assemble the KGD-6-AM (make sure the LED is aligned with the front case hole). 4-20 current loop test is complete. - Page 24 KELE FIXED GAS DETECTION PRODUCTS LIMITED WARRANTY Kele warrants the KGD-6-AM gas detector will be free from defective materials and workmanship for a period of two (2) years from date of manufacture (indicated on the inside cover of the KGD-6-AM), provided it is maintained and used in accordance with Kele instructions and/or recommendations.
