8. MAKING THE SYSTEM WORK
8.1 Commissioning the Wired System
The current loop needs to be commissioned to enable the system to locate and identify every actuator.
The master station and computer can be used to perform the commissioning. At the time of
commissioning the loop, all the actuators must be made available, though they may be locked in ‘hand
only’ control. All field units must have a unique network address.
The 2-wire loop and all the actuators should be connected to the master station, with all the actuators
left without power, except for the one furthest from port A. Disconnect the wires from port B and
browse to the master station web pages on the computer; go to System Diagnostics page – see
section 7.5.4.
Select Option 2 Diagnostics by clicking on the diagnostics button - see section 7.5.7.
Reset the network (current loop) by clicking the reset network button. The status information will
change and show the configuration stages. Once complete, the actuator furthest from port A should be
shown on the Network Map.
Power on the next nearest actuator to port A and reset the network again. This actuator should appear
on the list. Continue to power on the actuators and reset the network working back towards port A until
all the actuators are connected and appear on the map.
Now connect the port B wires and disconnect the port A wires. Reset the network and check that all
the actuators are still on the map. Having verified the loop wiring and the connection of all the
actuators in both directions; finally reconnect the port A wires, reset the loop and all the actuators will
be ready for control.
The commissioning sequence can also be carried out using the master station HMI screens using the
Option Module 2 Diagnostics. This is a 2 page menu and contains similar information to the web page.
Once the system is working with actuators connected and no loopbacks present, the diagnostic and
control pages can all be used.
See also the Quick start guide document: PUB059-026.
Always ensure the plant is in a safe condition and all the
actuator controls are placed in Local before commencing
any commissioning or fault finding on the system.
