Then, the user must press the Touchkey/LCD assembly downward till to the end. If above
alignment is correct, the J11 male connector in the ATB board will be seated into the
corresponding female connector in Touchkey/LCD assembly. The user will hear or feel
the click sound between their connection. If there is some problem, do not continue to
use brutal force, otherwise the J11 male connector in the ATB board or corresponding
female connector in Touchkey/LCD assembly will be damaged. The user must snap/pull
back the Touchkey/LCD assembly, and align them again to continue.
After that, screw the circular enclosure rear cover in place and secure it with the locking
screw (2mm Allen-Key).
The threads of the cover must always be well lubricated with grease. Otherwise, the user
will not be able to open the cover in future. In case of installation in hazardous areas,
then strictly follow the instructions in SF910i Safety Instruction Manual
(EC-DOC-G041MAN033), even for the relatively simple action of placing the cover in
place.
Some experience on the end of installation:
– After wiring, screw the circular enclosure rear cover into aluminum body. Normally,
there is a designed space between the cover glass and touch button. However, if
there is an abnormal, for example, flashing LCD display, it may be due to the space
between the cover glass and touch button is too small. The user could have a try
to screw the cover back a little (< 1mm).
– Grounding terminal of enclosure shall be connected to a good grounding point in
site to ensure touch key proper detection/operation.
– After the user screw back/ahead the cover every time, suggest to re-power on/reset
the SF910i, since that internal circuit will re-calibrate the touch-button
identification/sensitivity after powering on.
– Suggest to use volar pad of thumb to touch ▼ or ▲ (Downward/Upward) button,
especially due to that ▼ (Downward button) is near to the enclosure edge, using
the use volar pad of thumb would increase the touching area.
– If the site of installation is not hazardous area, the unit can be powered on while the
cover is still open.
