10 COMMISSIONING & SERVICE
This section details essential operational tasks and all first start-up procedures that
need only be performed once as part of the commissioning phase to prepare the product
for deployment in the field. Refer to the relevant sections below depending on the
installed options.
Note: A familiarity with the interface is assumed. If not, refer to the 'MA-040 – DGA
900 – Plus Operator Guide' for login details and general HMI functionality.
Installation and commissioning must be performed by trained field service
engineers only. Resetting certain attributes may lead to data loss if the
product is already operational.
Check that all the installed inputs connected to a signal for the thermal,
cooling and OLTC cards are reading values within expectations.
After installation, check that the pulled current by every cooling bank unit is
within 5% of the value entered in the cooling configuration page. If not,
update the values in the Cooling Configuration page to the measured
values and let the asset operator know that those values have changed.
At the time of commissioning, reset all models as outlined in this section
including parameters, counters and all related model data.
