APPENDIX 4 - Troubleshooting - continued
7. Alarm
I get alarms on screen but no
alarm dial out or siren.
7.1a
Do you have an auto dialer or audio alarm hooked to the controller? The controller
has an alarm connection but does not provide an alarm.
7.1b
Have you cleared previous alarms? Check the Alarms/Error menu for an active
alarm. Press ENTER to clear an alarm.
7.1c
Are your controller alarms hooked up as a normally closed series circuit? Do you
have a short across the wires between the controller and the alarm that prevents
the controller from communicating alarms to the alarm device?
7.1d
Is the alarm hooked up to the alarm relay connection on the controller input/output
board?
I get constant alarms.
7.2a
Is the alarm device hooked up to the proper normally closed or normally open side
of the alarm relay?
My feeder/water alarms are
increasing.
7.3a
As your animals grow, they consume more water and feed. Assuming they are
healthy, that you have no leaks in the water or feed lines, and that feed and water
are getting to the animals, you probably need to raise your limits.
7.3b
If your feeder shows a constant run time, make sure the Minimum Amps
calibration setting for the feeder sensor is above 0.
8. Communications
Communications station
is not talking with the
controller.
8.1a
Are the communications station and controllers wired properly? Multiple controllers
should be wired in parallel with the communications station. Check the polarity (+/-)
of the connections. See the instructions that came with the communications station.
8.1b
Is the modem set right for terminal or non-terminal position in wiring order? See the
instructions that came with the communications station.
8.1c
Ensure you have entered the controller’s serial number in the communication
software.
9. Purge Settings
My controller never purges.
9.1a
Purging does not occur when the curtains are open, so if they are always open, it
will appear that purging does not occur.
9.1b
Purge ON/DELAY times are incorrect. Make sure your times are in hours, minutes
and seconds. Refer to the
Operation Manual
for Purge Settings.
9.1c
High/low temp inhibits are wrong. Purges will not occur when inside temperature is
above high temp inhibit or below low temp inhibit.
9.1d
Do you have any sidewall fan groups designated as Purge fans?
9.1e
Are curtains set for the Natural operating mode and the Opening Temp is too low?
If curtains are opening on their own, they restart purge timer.
9.1f
Do you have purge openings for curtains or inlets set above zero?
9.1g
If Natural operating mode and only using humidity purge, make sure the humidity
sensor is working correctly
Fans purge, but they all run
at separate times.
9.2a
Check the time settings for your purge fans.
9.2b
Is the Power Up Load Delay Time set too long? More than a few seconds?
