The unit incorporates a command pushbutton located at the bottom right side of the faceplate, with three options: local,
remote, and off. The first option (LOCAL) allows executing operations in local mode (HMI, front RS232 port, and rear
COM2 port). The second option (REMOTE) allows operation execution only through remote communications (COM1 and
COM3 - Ethernet). The third option (OFF) blocks the execution of operations. Each position is identified with an LED
indicator, as follows:
LOCAL operations (green)
REMOTE operations (green)
OFF (red )
Press the command button to switch from local to remote operations mode and vice versa. OFF status (operation inhibited
for maintenance and safety) can be reach pressing the commands pushbutton during several seconds (local-remote-off
sequence).
4.2.4 FRONT PORT AND COVER SEALING SYSTEM
