4.2.9.2 - Outputs other than loaders
The test procedure is as described above.
Item 2* Status/test motor cooling valves circuit A
Item 3* Status/test motor cooling valves circuit B
Item 4* Status/test oil soleniod valves circuits A + B
Item 5* Status/test oil heater outputs circuits A + B
Item 6* Status/test oil pump outputs circuits A + B
Item 7 Fan stages status/test circuit A
Item 8 Fan stages status/test circuit B
In test mode, the or buttons in block 4
display 0001, 0010, 0100 and 1000 in succes-
sion, so as to force the various fan stages in
turn on each circuit. These items only apply to
air-cooled units.
Item 9 Alarm output status/test - Circuits A & B
In test mode, the or buttons in block 4
display 01, and 10 in succession, so as to force
each alarm output status in turn on each
circuit.
Item 1 Status/Test of loaders
These items display the status of the
compressors on circuit A or B. They can
also test them independently.
For example:
Test of loader 2 circuit A and loader 1
circuit B. The password must already
have been entered in the Configuration
menu. If not, the message “no” will be
displayed in block 2 (see section 4.2.10).
