Commissionning & final tests
Final Set-Up and Test
To test the set-up and ensure that the frequency
converter is running, follow these steps.
Safe Stop Commissioning Test
After installation and before first operation,
perform a commissioning test of an installation
or application making use of CD 302 Safe Stop.
Moreover, perform the test after each modifica-
tion of the installation or application, which the
CD 302 Safe Stop is part of.
The commissioning test:
1. Remove the 24 V DC voltage supply to terminal
37 by the interrupt device while the motor com-
pressor is driven by the CD 302 (i.e. mains supply
is not interrupted). The test step is passed if the
motor compressor reacts with a coast.
2. Then send Reset signal (via Bus, Digital I/O, or
[Reset] key). The test step is passed if the motor
compressor remains in the Safe Stop state.
3. Then reapply 24 V DC to terminal 37. The test
step is passed if the motor compressor remains in
the coasted state.
4. Then send Reset signal (via Bus, Digital I/O, or
[Reset] key). The test step is passed if the motor
compressor gets operational again.
5. The commissioning test is passed if all four test
steps are passed.
High Voltage Test
Carry out a high voltage test by short-circuiting
terminals U, V, W, L1, L2 and L3. Energize by max.
2.15 kV DC for one second between this short-cir-
cuit and the chassis.
NB: When running high voltage tests of the entire
installation, CD302 compressor Drive and com-
pressor electrical motor compressor test can be
conducted together.
Warning: when conducting an high voltage
test make sure the system is not under vacuum:
this may cause electrical motor compressor fai-
lure.
Never apply the high voltage test to the
control circuit.
