Table 21:
Function/ Parameter
Logic for four binary inputs with the following three
configurations:
• OR gate
• AND gate
• Bistable flip-flop with two set and two reset inputs (both OR
gates), resetting takes priority
Four independent parameter sets
All configurations have an additional blocking input. Provision for inverting all inputs.
Table 22:
Function/ Parameter
Pick up or reset time
Integration
• For delaying pick up or reset or for integrating one binary signal
• Provision for inverting the input
• Four independent parameter sets
