flow to close flow switch
within 60 seconds
Pump 2 did not provide
flow to close flow switch
within 60 seconds

Cooler flow switch contacts
open for 3 seconds after
initially made
Cooler flow switch contacts
open for 3 seconds after
initially made

when pump state is off
Pump 2 Auxiliary Contacts
closed for 2 minutes
when pump state is off
Cooler flow switch contacts
failed to close within
1 minute (if cooler pump
control is enabled) or
within 5 minutes (if cooler
pump control is not
enabled) after start-up
Flow switch opens for at
least 3 seconds after
being initially closed

pump control and flow
switch input is closed for
5 minutes while pump
output(s) are off
Master chiller MBB
