NOTES
1. Energized to reply to an oxygen transmitter. A pulse or a series of pulses will be observed, depending on what portion of the calibration
cycle is being performed. If the LED is on steady, it may indicate a PLC failure. Before replacing the PLC, reset the PLC by powering
down and powering up the IMPS 4000. Monitor the gas application portion of the calibration cycle once again. If the LED is still on steady,
replace the PLC.
2. Energized to select which oxygen transmitter will receive test gas during calibration. It is only energized during the gas application
portion of the calibration cycle.
3. Energized to apply either test gas. It is only energized during the gas application portion of the calibration cycle.
4. Energized when an oxygen transmitter is in calibration.
5. Energized if gas pressure is low.
6. Energized if a calibration has failed.
7. Energized when a test gas is flowing.
8. If energized continuously, reset by unattaching and reattaching the oxygen transmitter at the IMPS 4000 operator interface.
9. If energized longer than the AbrtTim set at the operator interface, reset using 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 Oxygen Transmitter Instruction Manual.
c. Reattach the oxygen transmitter at the IMPS 4000 operator interface.
10. If the output LED is illuminated but the remote indication is off, check the wiring from the IMPS 4000 to the remote device. Make sure the
wiring is in accordance with Figure 2-3. Note that the status outputs from the IMPS 4000 have shared common connections and remote
power is required.
