4.4 START-UP
9
Before start up the compressor, check the electrical and air line connections.
9
Check that the compressor’s cooling air inlets and outlets are not closed. Do not cover your
compressor with cloth, nylon etc. Do not operate if covered.
9
Inside electrical panel of your compressor there is a “phase control relay” that continuously
checks the phases. In case the phases are connected in reversed or if there is unbalance or
interruption in your voltage, the phase control relay will prevent operation of the compressor.
In this case, a signal behind the phase control relay that indicates the phase error warns you.
When the phases are connected reverse, switch off the energy and switch the position of main
cables of the compressor. In case of interruption or phase unbalance, as this problem is
related with the network contact an electrician or related institution.
9
When the energy and air lines of your compressor are completed, inform your service for
commissioning. Our service will perform the general inspections, start up the compressor and
supply you beneficial information related to your compressor and its maintenance. If you want
to start up the compressor by yourself read this handbook very carefully. Performing an
erroneous process may be hazardous for your compressor facility or the personnel working in
this region.
9
Check the oil level. On the oil receiver body there is a
transparent hose for easily seeing the oil level (on the belt
driving models). Check the oil level when compressor is at
the stop position. During operation the oil level may vary.
9
If the oil level is missing, complete it. Information related to
oil is described in section
5 (MAINTENANCE)
, part
“
COMPRESSOR OIL
”.
9
Oil level should not be below the mid-point of the hose
9
Check the internal components and connections of the
compressor. Make sure that during transportation it has not
been damaged.
9
Oil filling tap is on the compressor unit for the direct drive
models. While compressor is not working you can check the
oil level.
9
Oil level should reach beneath the pitch of the tap
9
Apply energy to compressor and see if the light is ‘on’ above
phase control relay in the electric board. If it is ‘on’ electric
connection is regular. If it is ‘off’ phase row is wrong
9
Apply energy to the compressor and check whether the
compressor motor is running in correct direction.
The running
direction control of compressor: should be made during
commissioning.
For this, remove necessary cover.
