4.
If one of the strain links is generating a blinking “HI” or “LO” message on the Load LED
display and an “Err” message on the Setpoints LED display, select that strain link to adjust
first. Otherwise, select any strain link.
5.
If the potentiometer adjustment screw on the strain link is not accessible via a hole in the
cover, loosen the two screws securing the cover, and remove it. The adjustment screw is
located on the strain link circuit board, as shown in Figure 3-1.
6.
Check the offset value for the strain link you are zeroing, referring to the Load LED
display on the AutoSet front cover. If the offset value is greater than ±5, perform step 7.
Otherwise, go to step 8.
When a Load LED display on the AutoSet front panel shows a value b50 and -50,
the corresponding Setpoints LED display shows dashes (---). When a Load LED display
shows a value greater than +50, the corresponding Setpoints LED display shows the
message “HI.” When a Load display is greater than -50, that Setpoints LED display shows
the message “LO.”
If the strain link zero offset reading is greater than ±99, the corresponding Load LED
display shows, in flashing letters, the message “HI” (if >+99) or “LO” (if >-99), and the
Setpoints LED display shows the message “Err.” All other Load and Setpoints LED
displays are blank. If multiple strain links have zero offsets outside the ±99 window, only
the displays for one strain link show the “HI”/“LO” and “Err” messages, the other displays
remaining blank.
The potentiometer adjustment screw is accessible through a hole in the cover on strain
links with a Hirschman connector (part no. 9641801 (standard) or 9685105 (metric)).
Newer versions of other strain links (part nos. 9641601, 9641602, 9641603, and 9641604
(standard) or 9685101, 9685102, 9685103, and 9685104 (metric)) may also provide an
access hole.
