    ZEN Programmable Logic Module 3.4. Protecting Programs ZEN has a password function, used to prevent incorrect use of the ladder program or to prevent manipulation of settings made by the controller. The password code may comprise the range 0000 to 9999 (4 decimal numbers).
  • Page 8 3.7. Stabilizing Input Operations If the ZEN external input fluctuates, it is possible that the operations will be unstable. To solve this, ZEN is able to filter inputs to stablilize the signal. The input filters can be set separately, either for the CPU inputs or for each I/O expansion unit.
  • Page 9 DC Input 15 ms 50 ms The input filter settings are read when ZEN starts the operation. 3.8. Backlight The LCD backlight is automatically activated when the operation keys are used. Depending on the setting (see below for more details), this light will switch itself off 2, 10 or 30 minutes after the function keys have stopped being used.
