System Environment Setting (Continued)
Contact point control pattern
Pattern
▶ No external input (Factory default setting)
Pattern1
When you input contact control signal in port 1, there will be no response.
▶ Level input (Emergency stop)
1. If the contact control signal is changed to ON, emergency stop status and all the
indoor units are given 'Stop' command, and controlling using remote controller is
impossible.
2. During the emergency stop, the DMS2 will ignore any request from the upper
controllers.
Pattern2
3. During the emergency stop, the DMS2 will ignore previously set schedules.
4. When the contact control signal changes from ON to OFF, DVM goes into normal
operation status and returns to the remote control status before emergency stop.
5. Even if the contact control signal of port 1 changes from ON to OFF, there will be no
change to the indoor unit.
6. When you input contact control signal in port 2, there will be no response.
▶ Level input (Operation/Stop, Remote control Enable/Disable)
1. If the contact signal of port 1 changes from OFF to ON, all indoor units will be given
'Operation' command.
2. If the contact signal of port 1 changes from ON to OFF, all indoor units will be given
'Stop' command.
3. If the contact signal of port 2 is OFF, you cannot control all indoor units using
remote controller.
Pattern3
4. If the contact signal of port 2 changes from OFF to ON, you can control all indoor
units using remote controller.
5. If the contact signal of port 2 changes from ON to OFF, you cannot control all indoor
units using remote controller.
6. Control command from the upper controller will be operated regardless of the
contact point status.
7. DVM system control using Schedule control will be operated regardless of the
contact point status.
▶ Pulse input (Operation/Stop)
1. Valid pulse duration for input signal is 0.5~1.0 second.
DMS2 ignores the signal which has shorter than 0.5 second duration, longer than
1.0 second Pulse width.
2. When Pulse input signal is ON in Port 1. all indoor units will be given 'Operation'
command.
Pattern4
3. When Pulse input signal is ON in Port 2. all indoor units will be given 'Stop'
command.
4. DVM control command from the upper controller will be operated regardless of
Pulse input signal.
5. DVM system control using Schedule control will be operated regardless of
