2. Functionality of the JT KS Gate Control Unit ... The gate control unit principally works in automatic mode.
This mode is controlled by the light sensor (LDR) and the pots (in figure 5 + 6 ) for morning and evenings.
The LDR light sensor continually measures the current level of brightness which is internally converted into a percentage ( 0% - 100% )
and serves as a reference value during automatic operation for other actions ( 0% = absolutely dark and 100% = direct sunshine).
If the curent level of brightness is higher or the same as the level specified for the mornings, the LED of the LDR illuminates. Only when
the current level of brightness is lower high or the same as the level the pot specifies for the evenings, the LED of the LDR switches off.
Pot for mornings ( 5 ) and pot for evenings ( 6 )
The pot for the mornings determines a minimum level of brightness in a % value that must be reached so that the gate control unit opens
the flap gate in the mornings ( OPEN ).
The value range has been determined as being 15% to 100% !
The pot for the evening determines how minimally dark it has to be so that the gate control unit closes the flap gate in the evenings (
CLOSE ).
The value range has been determined as being 2% to 12% !
Safety minute: If the respective level of brightness for the mornings or the evenings has been reached, a safety waiting period of one
minute has been programmed to run before each operation occurs. Afterwards, the automatic system checks again if the previous
triggering was valid or if it had to do with an unwanted incidental illumination or darkening.
Delay: Using this jumper (4) it is possible for the evenings to delay closing if the LDR detects that it is dark.
Jumper, left vertical 30 min delay
Jumper, right vertical 60 min delay
Jumper, lower horizontal - no function
Jumper, left and right vertical 90 min delay
Lag: With this delay using the pot (8) from 2 ms to 2000 ms (= 2 sec), it is possible to set the exact operation of the flap gate mechanism
with a self locking system.
LED ( LDR ) display: The yellow LED indicates if the light sensor has detected light = LED ON (light) or if the light sensor detects
darkness = LED OFF.
