START-UP
Checking the EvU display
Before starting:
1 Press the maint button, select menu item ADJ. OPT. ALIGN and call up with Enter
2 The optical reference position is now approached on devices with automatic beam
tracking.
3 Check the display:
4 Adjust the two screws on the device flange with a 19 mm wrench (
see “Aligning the opti-
cal axis”) until the display shows.
– the values for dx and dy are less than or equal to ±0.1 (dx…value for horizontal
position or adjustment)
(dy…value for vertical position or adjustment).
Values A, B, C and D are values of device-internal parameters. They should be in the range
450…650.
5 If the valid range for A to D cannot be reached even after adjusting the screws several
times and the values for dx and dy are ≤ 0.1, check the warning and error messages in
Diagnosis mode, (
see “Menu structure”, page 49), and take the appropriate
maintenance or servicing measures, see “Integrated monitoring and diagnosis system”,
page 120.
6 Switch to Measuring mode:
▸ Press meas.
Display in the LED matrix Meaning
LED in the middle lights up Optimum analyzer alignment.
A LED in the inner quadrant
lights up
Alignment within half the tolerance.
A LED in the outer quadrant
lights up
Alignment at tolerance limits, correction required.
A LED in the outer quadrant
blinks
Alignment outside tolerance limits, correction required.
LED in the middle blinks
No signal, reflector not “seen” by the SR-unit because,
for example, the alignment is completely wrong, no
probe is installed, reflector strongly contaminated.
LEDs in middle row light up
sequentially
No alignment possible during warming up phase, check
cycle or reference cycle.
