Terminal #01-02; lock keyboard:
Use the LOCK KEYBOARD function to connect a lock or jumper in order to disable the complete keyboard while the functions
from the terminals remain available. Certain keys on the keyboard can be locked-out with SETUP 85 or passcode-protected
with SETUP 84. Terminal #11 can block the batch process.
Terminal #03-07; flow meter input:
• A high or low frequency NPN signal can be connected to the PC200. For low frequency sensors like a reed switch, a low
pass filter on terminal #07 eliminates contact bounce. For higher frequencies, use terminal #06.
• Use terminal #05 for a 12V DC sensor supply. Use terminal #29 for 8.1, 12 or 24V DC.
• The screen of the signal wire must be connected to the common ground terminal #03 (unless earthed at the sensor itself).
Terminal #04 is not used.
• Active signals switching between 0…8V DC, 0…12V DC or 0…24V DC can be connected as well.
