(3) If line connection to the dialing destination is successful, input relay Xlmm05
(Connected) turns on.
Input relay Xlmm05 (Connected) turns off when the line is disconnected.
If line connection to the dialing destination is not successful, input relay Xlmm06
(Connection Failed) turns on. (Dialing destination is busy, etc.)
Turn off (RST P instruction) output relay Ylmm40 (Dial Request) on the ON rising
edge of input relay Xlmm05 (Connected), Xlmm06 (Connection Failed) or Xlmm08
(Disconnection Failed). Turning off output relay Ylmm40 (Dial Request) turns off
input relay Xlmm06 (Connection Failed).
If the line connection is unsuccessful and output relay Ylmm42 (Redial) is on so
that redialing is enabled, auto-dialing is repeated up to the number of times
defined in data position number 28 (Redial Limit) at intervals defined in data
position number 27 (Redial Interval). During the redialing, input relay Xlmm07
(Re-dialing) turns on. To cancel redialing, turn off output relay Ylmm40 (Dial
Request).
If line connection is still unsuccessful after the stipulated number of retries, input
relay Xlmm06 (Connection Failed) turns on and the auto-dial operation fails.

To disconnect a line, turn on output relay Ylmm43 (Disconnect Line) using the
SET P instruction. When the line is disconnected, input relay Xlmm05
(Connected) turns off. Turn off (RST P instruction) output relay Ylmm43
(Disconnect Line) at the falling edge of input relay Xlmm05 (Connected) or the
rising edge of input relay Xlmm08 (Disconnection Failed). Turning off output relay
Ylmm43 (Disconnect Line) or Ylmm40 (Dial Request) turns off input relay Xlmm08
(Disconnection Failed).
