NOTES
1. Energized by a digital output from the oxygen transmitter. If the LED is on steady, it indicates that the IMPS 4000 is not responding to an
oxygen transmitter request for a calibration. To correct, perform the following procedure:
a. Unattach the oxygen transmitter at the IMPS 4000 operator interface.
b. Abort the calibration at the oxygen transmitter. Refer to the O
c. Reattach the oxygen transmitter at the IMPS 4000 operator interface.
2. Energized when test gas pressure is high enough for calibration. Deenergized indicates low gas pressure. If low test gas pressure is
indicated by an unlit LED, verify that the test gas bottles are not empty. Check the piping from the test gas bottles to the IMPS 4000 for
leaks or blockages.
3. Energized when a remote system is requesting calibration. This must be a momentary contact. If the LED is on steady, a malfunction is in
the remote system or there is a short in interconnecting wiring. Locate and correct the problem.
4. RUN/TERM switch should be in the TERM position for proper equipment operation.
