Remote start/stop via digital inputs
A digital input will be used to implement the start/stop function. The function of digital inputs 2 to 7 are adjustable. In the below example DI2 is used.
- In the P18.02 menu, set the function of DI 2 to "Remote Start/Stop"
- In the P18.03.01 menu, remote start is defined as "Open".
- A remote stop will be generated if the contact is 'Open'. A start will be generated when the contact changes from an 'open' state to a 'Closed' state. (Rising flank)
- This normally open or closed state cannot be modified, and is fixed.
- In the P18.03.02 menu, a delay on the function can be assigned.
- The delay will only effect the remote starting, not the remote stop.
- There are 2 ways to enable this remote control via digital inputs.
- Set Parameter P10.12 'Start Source' to Equipment DI.
- Assign a second digital input function as 'Remote Start Enable' in the I/O config page p.18.
- when confirmed, a remote start/stop icon
will appear in the upper left corner of the display.
Remote start/stop via communications
- Communication terminals X05 and X06 are configurable. In menu page 'Equip settings' P10.
- If the communication is issued by a CMCVC product, such as for example a Metacentre, or another controller, the coms terminal has to be configured as 'Airbus485'.
- If the commonication is issues by a third party device, configure the coms terminal as 'Modbus Slave' to communicate to it trough the Modbus RTU protocol.
- Consult the fieldbus table to learn more about the registers used in the Q-controller.
- The fieldbus table is available on the support website.
- To enable the remote control via communications, Set parameter P10.12 - Start source to 'Communications'
- When confirmed, a remote start/stop icon
will appear in the upper left corner of the display.
The start source (P10.12) can also be configured as 'DI & COMM'. This allows both the digital inputs and communication commands to start and stop the compressor simultaneous. The digital inputs have a higher priority than the communication commands.
Pressing the local stop button on the controller diplays will always result in a stop. Regardless of how the start source is configured.
