③
• Not flashing: Relay contact 31/32 open, relay contact 31/34 closed
• Flashing: Delay time (ON-delay or tripping delay) running
• Masked out: Relay contact 31/32 closed, relay contact 31/34 open
③
Q
• Not flashing: Semiconductor output closed, supply voltage connected
• Flashing: Delay time (ON-delay or tripping delay) running
• Masked out: Semiconductor output open, supply voltage not switched through
You will find more information about the switching behavior of the output relays in Chapter
"Function (Page 59)."
