Installation and Troubleshooting Tips
Possible Problems and Solutions
5. Jobs are compiling in the JOBS WAIT-
ING queue or never clearing from the
ACTIVE queue.
A job that never closes out of the active queue or
never prints a report is an indication that one or
more control modules on the network have
dropped off-line; they may or may not have come
back on-line. This is usually caused by power to
the control module being momentarily interrupted.
Use the SETUP
"
DIAGNOSTICS
"
POWER
UP screen to check how many times each control
module has been turned on. The only way to clear
these jobs is to completely reboot the system (all
control modules at the same time). Make sure that
no new jobs are being entered and no fluid is being
dispensed during the reboot.
6. The system will not accept input of any
new jobs. This is indicated by a mes-
sage stating “SYSTEM FULL”.
This situation is related to problem 5. Use the RUN
"
VIEW CURRENT JOBS screen (see page 54)
to check if there are a number of jobs in the active
or waiting queues.
A job that is in the active queue will time out after
five minutes of inactivity. If a time shown in the
queue is more than five minutes old, the job is
probably “hung up” and will not clear. To correct
this problem, completely reboot the system (all
control modules at the same time). Make sure that
no new jobs are being entered and no fluid is being
dispensed during the reboot.
7. Unable to dispense one or more fluids
to a specific location on the network.
a. Check that the CAN network broadcasts to the
target control module.
b. Check that the solenoids and meters attached
to that control module are functioning.
c. Check that the system configuration informa-
tion for that Control Module was entered prop-
erly. The most likely problem will be errors in
the data in the ASSIGN CONNECTIONS table.
