This function allows the choosing of a different cycle end depending on the
configuration of the instrument (connection to a PLC or robot…).
a) Relay sequencing depending the End of Cycle
In order to interface the ATEQ D520 with its environment (PLC, PC …), the timing
charts below give the sequence for the electrical outputs (relay board on J8 connector)
and pneumatics (automatic connectors) according to the commands entered on the
front panel or on the J8 connector (START, RESET).
