3.4.2 Start-up Process for an IR4000S System
NOTE:
Powering on and off of the IR4000S and IR400 units is controlled from the
external power supply; refer to the power supply manual for instructions.
If you have any problems in the start-up or testing of the detector system, please refer to
Section 6.0
“Troubleshooting
” or contact General Monitors Technical Support. The Model
IR400 should be allowed to stabilize for approximately 60 minutes while each detector
attains the proper operating temperature.
IR4000S display sequence on power-up:
000 and Alarm indicator
All display elements (8.8.8.) and both Alarm and Warn indicators
Software revision (example: r C)
bSU (base Start Up)
SU (IR400 Start Up)
Gas concentration in % LEL
Upon initial power-up or after a fault condition has been corrected, the unit will enter a
start-up mode for 2 minutes before normal operation. IR400 Ethylene start-up can take
up to 10 minutes. As a unit warms up, output may briefly be negative.

Start-up
Operation and Configuration Tasks
In order to make sure that the IR400 detector and IR4000S menu functions are working
correctly, you should perform several tasks immediately after the system is powered on.
This section points you to detailed instructions for completing several start-up operation
and configuration tasks using the IR4000S menu system.
1.
Zero each connected IR400.
Zeroing eliminates any background gas fluctuations.
For instructions, see
Zeroing the IR400
in Section 4.3.
2.
Perform a gas check test for each connected IR400.
Verify that the IR400 is
measuring a known % LEL correctly by placing it in Gas Check Mode using the
IR4000S menu options.
You will need to use the GM Gas Check Kit (P/N 31468) to complete this task.
For instructions, see Gas Checking the IR400 in Section 4.2.
3.
(Optional) Configure additional IR4000S settings, as needed.
You may wish to
configure additional operating parameters directly after start-up, or you can use the
default settings initially and change them later on.
For a summary of all the IR4000S Menu Configuration options, see the topic
Setup in Section 4.5.
