Test the condenser fans, cooler pump(s) and alarm relay by
changing the item values from OFF to ON. These discrete
outputs are then turned off if there is no keypad activity for
10 minutes. Test the compressor and minimum load valve sole-
noid (if installed) outputs in a similar manner. The minimum
load valve solenoids will be turned off if there is no keypad
activity for 10 minutes. Compressors will stay on until the
operator turns them off. The Service Test mode will remain
enabled for as long as there is one or more compressors
running. All safeties are monitored during this test and will
turn a compressor, circuit or the machine off if required. Any
other mode or sub-mode can be accessed, viewed, or changed
during the Manual Control mode only. The
STAT
item (
Run
Status
VIEW
) will display “0” as long as the Service mode is
enabled. The
TEST
sub-mode value must be changed back to
OFF before the chiller can be switched to Enable or Remote
contact for normal operation.
NOTE: There may be up to a one-minute delay before the
selected item is energized.
