adjusting new parameters during the timing operation are
possible.
Keyboard function during timing/counting
The keyboard disabling (LOCK) is activated, if the keys "<"
and "R" are pressed while connecting the supply voltage.
By this the keyboard can be blocked against inadvertent
adjusting in critical applications. Deactivating is effected by
renewed actuation "<" and "R" while switching on the supp-
ly voltage.
Reset functions
By operation of the backspace key "R" or the RESET-input
(1-2) the ENS20 is set to the programmed preselected
value in each operating condition. The RESET signal (1-2)
and "R" - key have priority in relation to the START signal.
