6. Commissioning
WARNING !!!!!!
In order to commission the Energy Tech 301, it is necessary to work closely with mains
voltages. Only trained and competent persons should commission this unit using insulated
tools and wearing the appropriate safety equipment. The technician should acquaint himself
with site safety instructions and proceed with due caution.
Ensure that the dust collector is in good working order with no leaking filter bags and the
process is not subject to upset conditions. It is essential to the future accurate operation of
the EnergyTech 301 that the dust collection system is operating at its normal efficiency.
Failure to do so may result in poor results when the system is returned to normal.
Energy Tech 301 Commissioning
1. Power-Up:
a. Turn on the power
b. Wait for power-up sequence to complete and Data validity:
Wait for data valid LED (green) to come on.
In normal working conditions, the data valid LED will come on when the
power-up time has elapsed (by default, set to 0x01 minute
– byte at 0x7E48)
and the system has performed the configured calibration (by default, set to
Zero Calibration (0x10)
– byte at 0x7E49).
2. Zero Check
a. In Setup Mode scroll to 4.9 passcode, input password 1234 and press enter.
b. Still in set up mode select 4.3 parameters, scroll to find running mode and set the
running mode to maintenance. Press enter to exit.
c. In setup mode, select 4.2 span cal and set the span target to 00.00%.
d.
Still in 4.2 span cal, select the span path ‘Elec span sim’ then press enter to exit.
e. In mode 4.3 parameters
, scroll to running mode and select ‘Normal’ press enter to
exit.
3. Insitu Span calibration (Hardware Gain setting):
a. In setup mode 4.2 Span cal set the span cal target to current emission level if known
(10% by default)
b. Still in 4.2 Span Cal select
‘Insitu span cal’ and then press enter to initiate an insitu
span cal.
i. Waiting for ISC will be displayed and Data valid LED should go off for around
5 minutes and come back on upon successful completion of the span cal. A
span cal failure is usually due to wrong span target, if this situation occurs,
the analyser will keep pre-span cal data.
ii. In the event of a span cal failure, the Span error cal should be cleared then
make adjustment manually enter setup mode 4.4 signal:
Clear span cal error by sending clear performance error command
0x00002 to 0x000E/0F
Set stage 1 gain to minimum by sending 0x0000 to 0x00FF
Set stage 2 gain to minimum by sending 0x0001 to 0X0004
Adjust stage 1 gain to mid-range by sending 0x007F to 0x7E76/77
If emission levels are below 5%, apply x10 gain to stage 3 gain by
sending 0x0002 to 0x7E7A/7B then reduce stage 1 gain until the
emission levels are around 10%.
