Functional Check 6.7
The SafEye system has been calibrated at the factory for the user's specific
gas or vapor detection requirements. The functional check procedure
validates the system’s functional operation. The functional check filter is a
convenient operational check used to confirm that response has not
changed from previous readings. The filter is not used for calibration, since
it is unnecessary in the procedure, nor does it equate to a particular
quantity of gas.
Caution : Disable automatic activation and disconnect any external device
that should not be activated during the calibration check.
Notes :
 This functional verification procedure is for a standard 0–20mA output.
 Prior to starting the functional check, verify that the power to the units
is on and that the current of the 0–20mA channel is stable. Record the
reading.

To perform the functional check:
1
Position the functional check filter in front of the SafEye Detector.
2
Center the functional check filter's window over the detector’s
viewing window.
3
Wait 20 seconds.
4
Read the 0–20mA current. Determine the difference between the
reading taken with and without the functional check filter. This
difference is the 0–20mA current variance.
5
Record the 0–20mA current variance in the maintenance logbook.
If the variance is more than a 30% change when compared to the
previous check (see delivery form), repeat the alignment.
