Reverse Flow Limit
-
CHANNEL #<>
The amount of reverse flow for the
indicated CHANNEL has ex-ceeded
the maximum allowable amount as
defined in the CHANNEL parameter
set.
Last digit indicates CHANNEL #.
Check the following:
1. That the Reverse Flow value entered
in the JOB # is correct.
2. Flow meter fiber-optic cables are
properly connected and not reversed.
3. Fluid pressures are properly set and
stable.
4. All check valves are operating cor-
rectly.
5. All fluid lines filled and all valves
open.
6. Flow meter is operating properly.

Flow Too Low -
CHANNEL #<>
The flow rate for the indicated
CHANNEL # is too low. Based on
the transducer output. Not issued
for a manual GUN, master
CHANNEL.
Last digit indicates CHANNEL #.
Check the following:
1. There is fluid in the fluid lines for the
indicated CHANNEL.
2. Fluid pressures are properly set and
stable.
3. The pilot air line to the fluid regulator
is not damaged or leaking.
4. Fluid viscosity is correct for the
CHANNEL pressure and pipe size.
5. The pressure transducer and regula-
tor are operating properly.
6. Transducer air supply is at least 90
psi.
7. Kp, Ki, and Kd Gains are set correctly
for the indicated CHANNEL.

Flow Too High The flow rate for the indicated
CHANNEL # is too high. Based on
the transducer output. Not issued
for a manual GUN, master
CHANNEL.
Last digit indicates CHANNEL #.
Check the following:
1. Fluid regulators - sticking or faulty.

No Master Flow Manual mode only. A trigger signal
was received and no fluid flow
was detected through the master
chan-nel after the Blowoff timer had
elapsed (if used).
Check the following:
1. There is fluid in the fluid lines for the
indicated CHANNEL.
2. Fluid pressure is OK.
3. The flow meter, pressure trans-ducer,
and regulator are operating properly.
