6.
Guide a three-conductor, shielded cable or three wires in conduit through the top
conduit hub of the junction box.
7.
Connect the three wires to the power/signal terminal strip as follows.
•
Connect the +24 VDC wire to the terminal labeled 24 VDC IN +.
•
Connect the feedback wire to the terminal labeled FB.
•
Connect the - wire to the terminal labeled 24 VDC IN -.
CAUTION:
Leave the ground (shield) wire insulated and disconnected at the Eclipse.You will
connect the opposite end of the cable’s ground wire at the device.
8.
Re-install the control PCB (and ribbon cable if necessary). Be sure the ribbon cable is
routed down below the control PCB so it will not be damaged by the cover when it is
screwed back on.
9.
Secure the junction box cover to the junction box.
10. At the recording device, gas monitor controller, or programmable controller, connect
the cable’s ground (shield) wire to an available chassis ground.
Start Up
This section describes procedures to start up the Eclipse and place the detector head into
normal operation.
Introducing Incoming Power
1.
Complete the installation procedures described earlier in this manual.
2.
Verify that the power and detector wiring is correct and secure.
3.
Turn on or plug in the incoming power at the power source end.
4.
Verify that the LCD display is indicating the gas reading.
CAUTION:
Allow the detector to warm up for 15 minutes before you continue with the next
section, “Setting the Fresh Air Signal.”
Setting the Fresh Air Signal
Note:
For combustible gas and toxic versions of the Eclipse, setting the fresh air signal
requires setting the zero signal. For oxygen versions it requires adjusting the
span setting.
CAUTION:
If you suspect the presence of combustible gas, toxic gas, or that the oxygen content
is not normal in the monitoring environment, use the calibration kit and the zero air
calibration cylinder to introduce “fresh air” to the detector and verify an accurate
fresh air setting.
