    Model IR4000S 4.2 Gas Checking the IR400 You can ‘gas check’ an IR400 unit to verify response without tripping relays. During gas check mode, the Alarm and Warn relays are disabled. CAUTION – The analog output from the IR4000S is directly connected to the IR400 being used and this analog output will indicate gas present when the IR4000S is in Gas Check Mode.

  • Page 24: Calibrating The Ir400

    Model IR4000S 4.4 Calibrating the IR400 You can calibrate the IR400 which is connected to the IR4000S unit in order to make sure the LEL measurements are accurate. During calibration, the IR400 analog output is 1.5 mA, in order to disable the Alarm and Warn relays. Equipment required: Calibration cup, tubing, calibration gas tank with regulator.

  • Page 25: Setup

    Model IR4000S NOTE: Once gas has been applied, it is not possible to stop calibration. If no gas is applied for 6 minutes after calibration is selected from the IR4000S menus, the detector automatically reverts to a fault condition. A fault also occurs if the gas is not removed within 6 minutes from the beginning of calibration.

If a particular entry hole is not used, it must be plugged during operation in the field.

  • Page 29: Troubleshooting

    Model IR4000S 6.0 Troubleshooting CAUTION: Component level repair must be undertaken either by General Monitors personnel, or by competent, authorized service engineers. SMT PCB repair shall only be performed at a General Monitors facility. Failure to comply with this requirement will invalidate the warranty.
  • Page 30 Model IR4000S ACTION – Purge the detector with clean air or nitrogen, to remove any residual gas from the gas check. Verify that the area around the detector is clear of gas and that all gas check sources have been shut off. When gas is no longer present, the fault will clear. F3 –Detector Non-Critical Fault Indicates the IR400 or IR2100 detector requires attention such as cleaning the windows.
  • Page 31 Model IR4000S F8 – Fail to start zero Indicates that the IR4000S does not detect the proper mA input of 1.5 mA from the IR400. ACTION – Check the wiring between the IR400 and IR4000S, particularly the connection of the IR400 CAL wire to CAL IN at TB1-2.
