4. Commissioning
With all the batteries, load and AC cabling wired, and checked for correct polarity, the system is commissioned by
the following steps:
• Ensure no rectifiers are installed in the Power shelf and no load is applied.
• Close Battery breaker 1 and check (audible) that the LVDS closes.
• Plug in the Controller – it should power up off the battery. If not, it is possible that the battery polarity is
reversed.
• Set up the Controller menu items for:
o number of batteries and size (Ah),
o number of rectifiers,
o set the required float and equalize voltages,
o set LVDS option to Auto and set the LVDS Aux to “Normally Open”
o set the Battery Switch to “Normally Open”
o set the Cct Switch to “Normally Open”
o set the Battery Transducer FS as: (24V systems)
o set the amount of battery temperature compensation voltage adjustment if used and after
confirming that the battery temperature is being measured
o set the battery charging current limit to 10% of the Ah rating (i.e. if 150Ah battery is used, set the
limit to 15A) – this value can be adjusted later to meet your specific charging requirements.
In many cases, these values are set up in the factory and will only require modification if the particular
battery being used requires a different set up.
• Close the remaining battery circuit breakers if more than one string is used.
• Insert a switch-mode rectifier (RECTIFIER) in position 1 and apply the AC power. The rectifier unit
should power up and begin charging the battery bank/s.
• Insert all the remaining rectifiers (RECTIFIERs) and apply AC power to them.
• Check that the bus voltage is increasing toward the float voltage.
• Close the load circuit breakers and check that the loads power up.
• Wait for 1 minute and check that the rectifiers are all sharing the load current to within +/-2A of the
average rectifier current.
• The system is up and operational. Adjust any operational monitoring or setup details as required (see the
next section on Operation or refer to the Controller Operation Manual on the CD for a detailed explanation
of the functions)
