ADDITIONAL FUNCTIONS
Holding down the C button
By keeping pressed the
C
pushbutton for 5 seconds, the measured weight is zeroed. If this
button is pressed for 5 seconds with load inside the car, once the load is removed the
699Plus will show a negative measure. Pressing and holding down the button again, new
zero is stored and the display will show positive load once weight is placed inside the cabin.
Zero is stored into EEprom memory.
Compensation Chain and Relays block function
When doors are closed, feed between
INPUT1
(terminal 5) and
EXGND
(terminal 6 =
GND/common reference) a voltage coming from door relay where:
0 Vac/dc = lift DOOR OPEN
.
+12/24Vdc (9/18 Vac) = lift DOOR CLOSED.
In case of black out, send cabin to lowest floor and reconnect the 699Plus control unit again
to the power supply. 699Plus will automatically re-check and activate the compensation
function.
