Electronic position controller (N)
Controller software equipment:
A) Function and parameters
programmable functions:
•..with functional buttons SW1, SW2 and LED diodes D1, D4 directly placed on controller
•..with computer or terminal equipped with corresponding programme, using RS 232 interface.
programmable parameters:
•..control signal
•..response to SYS-TEST signal
•..mirroring (ascending/descending characteristics)
•..insensitiveness
•..EA limit positions (only with computer and ZP2 programme)
•..way of regulation
B) Operation states of controller
Error message from error memory: (using LED diodes and RS 232 and personal computer)
•..control signal missing or faulty
•.. input value of current control signal under 3.5 mA
•..existence of SYS-TEST signal
•..activity of switches
•..failure of feedback position transmitter
Statistic data: (using RS 232 and personal computer)
•..number of controller operation hours
•..frequency of relay switching in direction "opening"
•..frequency of relay switching in direction "closing"
