XIII. Troubleshooting
a. Check that the battery is firmly connected to the control panel and confirm
that it is fully charged.
b. Press the Pump Test buttons on the front panel. The test buttons should
always run the pumps, regardless of the state of any of the inputs.
c. Turn the power switch off for 1-2 seconds then back on to reset the sampler.
d. Check the Status LED on the front panel.
i. The LED is off: If the water sensors are being used, check the Rain
and Water Sensor inputs. Sensors must be in contact with moisture
and unused inputs must have one of the shorting plugs supplied with
the sampler plugged into the jack. If the Trigger Inputs are being used,
confirm that External Trigger mode is selected on the Interval control.
Check the pulses coming from the triggering device and confirm they
meet specifications. Test the Trigger Inputs by plugging one of the
shorting plugs supplied with the sampler into the jack.
ii. The LED is blinking: Check the Start Delay and Interval settings. The
sampler may be waiting for the Delay timer to run out or it may be
timing the interval between composite samples.
iii. The LED is on constantly: Check the bottle switches. The light
remains on when both sample bottles are full or when both float
switches are not plugged in or working properly. Plug one of the
shorting plugs supplied with the sampler into one of the bottle switch
jacks, the light should go out or start blinking.
