8. LED indicators
The code lock features 4 LED indicators. One of the LEDs functions as a status indicator. Two

Main LED (green):

indicates when a button is pressed. (See the LED signals table for details.)
Lock/Auxiliary LED (red) - output 7:
You can use a jumper to assign the following functions to this LED:
• Lock - Jumper to „inhibit“: The LED turns on when the codes for user group 1 are disabled
with a super user code, or when an incorrect code is entered repeatedly. For details, see the
settings for program code 70.
• Auxiliary indicator - jumper to „AUX“: This setting allows you to manually control the LED.
The LED is connected to the positive power supply terminal via a 1.5 kOhm resistor. The
negative terminal is connected to output 7 – this makes the LED turn on when the output is
connected to GND(-).

3 is the negative terminal and connection 4 is the positive terminal. A 3.3 kOhm resistor is con-
nected in series.

5 is the negative terminal and connection 6 is the positive terminal. A 3.3 kOhm resistor is con-
nected in series.
Keypad backlight (only for devices with a keypad backlight): The keypad backlight is dimmed
when the code lock is in standby. When a button is pressed, the keypad is fully illuminated for
10 seconds. The code must be entered within 10 seconds, otherwise previous entries will be
deleted and the backlight will automatically dim.
