HGM300/RDM800 PREVENTATIVE MA INTENANCE AND TECHNICAL SUPPORT SECTION 1 – HGM300 CPU reset, RDM800 CPU rese t, WARM UP notes and HGM300 Self Test SECTION 2 - HGM300/RDM800 Mechanical Room layout SEC.
SECTION 1 HGM300 / RDM800 TECHNICAL SUPPORT NOTES HGM300 CPU RESET Locate the white button m arked “CPU re set” on the main HGM30 0 board (about t he center of the m ain board). Locate the second reset button to th e left of the CPU reset bu tton .
valve check starts at zone 16 and works down to th e purge solenoid. A four zone m onitor there is a ten seconds of silence before the valves start to click. All lights on the HGM300 go out. The Yellow light on the RDM800 will come on after a few moments (Time out error).
SECTION 2 HGM300/RDM800 Refrigerant Gas leak monitor mechanical room placement Sample Inlet Pickup Points Chiller RDM800 Remote Display Module Outside Hallway Machine Room Exhaust Fan Aux.
SECTION 3 HGM300 Relay Connector Rela y #1 COMMON NO NC Rela y #2 COMMON NO NC Rela y #3 COMMON NO NC Rela y #4 COMMON NO NC Alarm Alarm Alarm 1 2 3 Fault Aux. Power Main Power Line Neutral Strobe Horn Line Neutral Jumper the ‘Neutral’ of the auxilia ry power connector to the ‘Com mon’ on the relay block.
SECTION 4 NO FLOW CHECK PROCEDURE NO FLOW ZONE Check f or air sample t ube blockage. NO FLOW PURGE Check for blockage o f purge line. Verify that the purge line do e s no t exceed 100’ in length. NO FLOW ZONE AND NO FLOW PURGE Check the water trap. If full of water, drain and re-secure the petcock.
ADDITIONAL NOTES ON “NO FL OW” PROBLEMS (THE FLOW RATE OF THE PUMP IS 2L/MIN) A DIFFERENCE OF LESS THEN 0.1 PSIA BETWEEN AMBIENT AND PRESSURE WILL CAUSE A “ N0 FLOW” FAULT. A VACUUM OF 0.7 PSIA OR LESS BELOW PR ESSURE WILL CAUSE A “N0 FLOW” FAULT.
NO FLOW PROBLEMS 1) – Pinch off the tubing between the water trap and internal filter. Go to the diagnostic screen on th e RDM800. Observe the “PRES”, “ VAC” AND “AMB ” r eadings at the bottom of the screen.
HOW TO FORCE T AKING NEW PRE SSURE READINGS FROM THE SYSTEM SCREEN SELECT THE HGM300 THAT NEEDS A NEW PRESSURE READING AND PRESS THE BUTTON T O THE LEFT OF THAT HGM 300. THIS WILL TAKE YOU TO THE HGM SETUP SCREEN. ON THE BOTTOM RIGHT SIDE OF THIS SCREEN PRESS THE BUTTON TO THE RIGH T OF “SERVI CE MODE ENTRY” TWO TIME S WIT HI N T HREE SECONDS.
SECTION 5 Clipping Fault Adjustment Locate R-34 Gain adjust potenti ometer. Adjust DETECTOR voltage using the Diagnostic screen until the voltage is 4.24 volts. If the reference volta ge is prop erly set, the clipping fault will go away after the unit samples the next zone.
HGM300 Refrigerant Gas Leak Monitor Dual Loop 4 to 20 mAdc Scrolling Output Converting 4 to 20 mAdc to 1 to 5 V dc Output Loop #1 indicates the sample zone number; i.e. 5 mAdc = Zone #1 … 20 mAdc = Zone #16. The output of Loop #1 will be fixed by the number of sampling zone solenoid blocks attached to the main board.
SECTION 7 Red Blinki ng LED Indicates Com munication Functioni ng Connector J9 Pin (-) 1 to Pin 10 (+) +5 volts DC (Comm unication voltage ) Pin (-) 1 to Pin 8 (+) -15 volts DC Pin (-) 1 to Pin 9 (+) .
HOW TO: SILENCE ALARMS on the HGM300 SECTION 8 THERE ARE 4 STEPS: STEP #1: Start at this screen, the “SYSTEM SCREEN”. STEP #2: PRESS THIS BUTTON, which will take you to the “ALARM SUMMARY SCREEN”. STEP #3: Each alarm must be acknowledged separately.
HGM300 Refrigerant Gas Leak Monitor NDIR Bench Measurement Description Pyroelectric Detector S a m p l e F l o w NDIR Source Dual Optical Bandwidth Filters Gas passing through the bench absorbs some I-R ener gy.
5.) Auto zeroing or purging has other benefits. We di sc ussed how it’s used to provide a zero b ase for comparison to the sample measurement. This, al so, allows us to monitor and compensate for changes in I-R drive circuitry, source, bench, detector, and other electronic components.
SECTION 10A M1110AX-A Testing HGM300 Monitors Using Gas Verification Kits SCOPE This procedure describes the steps necessary to use the gas verification kits, to verify operation of an HGM300. MATERIALS USED • Reference Gas • Variable Flow regulator • HGM 300 Refrigerant Monitor • RDM 800 PROCEDURE 1.
8. Verify that the unit is not in a purge cycle. This can be done by verifying a flow of air into zone 1. Read the (PRES) reading in the diagnostic screen (write down reading). 9. Connect the tubing from Reference Gas regulator to Zone 1 on the manifold of HGM 300.
SECTION 10B M1110AY-A Testing HGM300 Monitors Using Ga s Verification Kit and PC Software SCOPE This Procedure describes the use of gas veri fication kits with the HGM300 PC software. MATERIALS USED • Reference Gas • Variable Flow Regulator • HGM300 Refrigerant Monitor • HGM300 PC Software PROCEDURE 1.
9. Connect the tubing from the reference Gas re gulator to Zone 1on the manifold of HGM300. NOTE: Fault light on HGM300 may illuminate until gas starts to flow from the reference bottle. Press the enter key from keyboard the sensor readings will update indicated by a beep sound from the HGM300.
SECTION 11 TO ENTER A SYSTEM PASSWORD PR OTECTED OR CHANGE A PASSWORD 1) The system must be up and communicating. 2) Press the button to the left of “HGM# 1”. 3) When the “PASSWORD” screen appe ars enter “313” as the password. 4) From the System Screen, go to the RDM SET UP Screen.
