5.5.1. Start-up
Before powering the cabinet wait at least 15 seconds to be sure that the PC
embedded inside the equipment starts correctly.
Before operating the equipment, check that all LIMITS from the equipment are
correct. Please take care that CNG equipment are bidirectional, this means that
the equipment can consume or inject current. The equipment can operate as a
source or as a load.
Before running the equipment, please check all the limits and alarms.
Switch on the thermal-magnetic circuit breaker of the grid side of the power supply. After
switching it on, the power supply will initiate the start-up sequence. This sequence will activate
the cabinet fans for one second.
At this point the power supply will start the initialization process, as described previously. During
this time the embedded PC will load the operating system and the communications program.
The power supply will ignore any command during this process.
The Initialization state can last up to 15 seconds. If every step is completed successfully the
power supply will move automatically to Standby state.
Summarizing, to put the equipment in Run state the user should follow step by step the next
checklist:
1. Connect the mains.
2. Turn on the thermal-magnetic circuit breaker Q1.
3. Activate the cabinet output by switching the disconnector Q2.
4. Deactivate the emergency stop (pull out the button). (Initialization
Standby)
5. Send the Enable signal. (Standby
Precharge
Ready)
6. Select the connection mode between Independent or Parallel phases. This option
cannot be undone while the power supply is running.
7. Select the operation mode. Please keep in mind that not all EUTs are compatible with
all operation modes. For example, if the power supply is acting like a voltage source, do
not connect any other voltage sources at the output. In AC mode, the connection mode
cannot be changed during Run operation. In DC mode, the connection mode can be
changed during Run.
8. Send the Run signal (Ready
Run)
