Troubleshooting
First, inspect the unit for signs of physical damage
which should indicate abuse, or that it has been dropped
or exposed to dust, dirt, corrosive fumes or liquids.
Unit dials out but I get no fax:
• Are you dialing the correct phone number?
• Is there toner in the receiving fax machine?
• Has the unit been connected to power or is
the battery dead?
• Is the AC adapter working?
• Has the unit been set up properly?
I programmed name and location but they don’t
show on the fax received:
• Did you do a system reset (“ON & “SET” keys)
and wait 15 minutes?
None of the keys work:
• Has the unit been connected to power or is
the battery dead?
• Is the AC adapter working?
• Is the unit sending a fax? Keys are disabled
during sending a fax and are not supposed to
work.
• Not sending a fax? Try pressing “ON” & “ESC” to
reset it.
Clearing and Resetting:
To clear all data and reset the unit, press and hold
the “ON” key and the “SET” key for 2 seconds, and
then release the keys. A scrolling message should appear
warning you that continuing with this operation will clear
the logger. You have the choice of continuing by pressing
“SET”, or aborting by pressing “ESC”. Pressing “SET”
will clear the logger. If the scrolling message does not
appear, try the key sequence again, holding the keys
slightly longer or shorter times.
Unit will not dial out:
• Is the phone line you are connecting to an
analog line? It won’t work on a digital type line
or system.
Alarms and Messages
Included on the faxed chart is a set of conditional
symbols that tell you under what circumstances the fax
was sent.
1. Fax On Demand
This indicates that the chart was sent when the user
pressed the “Send Fax” button. A normal timed fax,
(one that gets sent when the faxing interval time occurs)
will not have this message on it.
2. Alarm
This indicates that the fax was initiated by an alarm
condition. These occur when conditions exceed those
that are programmed in the alarm minimums and
maximums. (See Programming the Unit, Setting Alarm
Mins and Maxs section) or the AC power has been
disconnected.
The particular condition that triggered the alarm fax is
indicated by an icon. Descriptions follow:
3. Thermometer
This means that the temperature has exceeded one of
the minimum or maximum values that is programmed to
trigger an alarm situation. For an FX320, thermocouple
model, there is a thermometer icon for each channel.
4. %RH (only on humidity units)
This means that the relative humidity has exceeded
Once the unit is cleared and reset, you must now wait
at least 15 minutes while chart messages are reconstructed
internally before a fax may be sent.
Resetting the Unit:
To reset to a normal state, WITHOUT CLEARING DATA,
press and hold “ON” and “ESC” simultaneously for 2
seconds. This may be used in the case where the display
freezes up.
• Do you have to use an access code to get an
outside line?
• Is power connected and is the battery good?
• Are you dialing the right number?
• Is the modular cable good and plugged into
the right jack (top one) also, is it plugged into
correct jack on the wall?
There is a blank space in the data graph:
• Does the blank space correspond to the time
when the fax was being sent? If yes, logging
is disabled during a fax transmission and this is
normal.
The Display doesn’t work:
• Is the unit connected to AC power? If not,
unit is in sleep mode.
Reset:
To reset the unit, but not clear the saved, press and
hold the “ON” and “ESC” keys for 2 seconds.
The readings are incorrect:
Return the unit to Dickson for calibration.
Only one of the graphs show:
Temps > 100˚ or < 0˚ will not be seen. If RH
graph shows but no temperature and the unit is in an
environment ranging from 0-100 then one of the internal
sensors could be bad and needs to be replaced. Return
unit for repair.
It faxes, but the graph area is blank or partial:
The unit actually stores two days worth of data. At
midnight, the unit switches from writing data to the
previous day’s chart, to writing for the present day’s chart.
If the unit is set up for a timed fax, and there has not been
a complete previous period’s worth of data logged, then
the fax may appear blank or have blank areas.
The unit has been pre-programmed at the factory to
sent the previous day’s graph at 1:00AM. If you elect to
change this time, it may take up to 2 days before a full
chart of data will be seen.

If you choose “YES” in the “SET ALARMS” menu, the
next menus you see will be where you can adjust the
minimum and maximum temperatures or humidity which
will trigger an alarm situation. The Yes/No screen just
allows you to skip over four more menu options if you
have no need to change any of them at this time. The
values are saved in memory and exist even when alarms
are not enabled. They can can be turned on or off at any
time. Any one of the min/max settings can be modied
independently of the others. If you only want to change
one of them, you can adjust it, program it and skip over
setting the others. Or, you can modify all of them, or any
combination you want.
For each of these menus there is a two second delay
and then the screen will switch to a display of the current
setting for that particular min/max adjustment.
To adjust the value, press the “DOWN” or “UP” keys
to decrease or increase the number by 1, and to ne
tune, press the “LEFT” or “RIGHT” keys to decrease or
increase the number by .1 or one tenth.
To save any adjusted setting, press the “SET” key. To
exit without saving, press the “ESC” key. If you need
to re-program any other mins or maxs, just press “SET”
until you get to the menu choice you want, then wait for
the 2 second delay to take you to the edit screen. Note:
Maximum and minimum values are limited by the range
of temperatures or humidity that the unit is capable of
withstanding.
There are currently ve alarm conditions:
“Alarm Temp Min”
“Alarm Temp Max”
“Alarm RH Min”
“Alarm RH Max”
“Battery Mode”
If the unit senses an alarm condition continuously for
more than (about) 10 seconds it will start sending an
alarm fax. The alarm fax will indicate all alarm conditions
currently active. High/Low just show as Ch. 1 and Ch. 2
or temperature and %RH. Once an alarm condition has
been faxed, it will not send another fax until midnight
has been passed, or the system block has been reset.
If, however, another different alarm condition occurs, all
current alarm conditions will show on the fax.
The Battery Mode alarm level is preset at the factory
and is not adjustable.
Clearing and Resetting:
To clear all data and reset the unit, press and hold the
“ON” key for 2 seconds, then press and hold the “SET”
key for 2 seconds, and then release the keys. A scrolling
message should appear warning you that continuing
with this operation will clear the logger. You have
the choice of continuing by pressing “SET”, or aborting
by pressing “ESC”. If the scrolling message does not
appear, try the key sequence again, holding the keys
slightly longer or shorter times. Clearing and resetting,
or Reset are ignored while a fax is being sent.
Once the unit is cleared and reset, you must now
wait at least 15 minutes while chart messages are
reconstructed internally before a fax may be sent.
Resetting the Unit:
To reset to a normal state, WITHOUT CLEARING
DATA, press and hold “ON” and “ESC” simultaneously
for 2 seconds. This may be used in the case where the
display freezes up.
Setting Fax Date and Time:
Next Fax Date
This menu option will appear if you have selected a
faxing interval of weekly or monthly. You program the
Next-Fax-Date in the same way as the internal clock date,
(see Setting Date and Time).
Next Fax Time
This value is programmed in the same way as the “Set
Time” mode, (see Setting Date and Time). It also uses
the same military time system. For a daily fax interval,
this setting determines what time the fax will be sent
every day. For a weekly or monthly fax interval, this
setting determines the time the fax will be sent on the
date that was programmed as the Next-Fax-Date.
Default Fax Date and Time
If you do not program a time and/or date for the
fax to occur, the unit will use the factory pre-set default
values. For a daily fax, the default Fax Time is 1:00 AM.
For a weekly fax, the default is Sunday at 1:00 AM. for
a monthly fax, the default is 1:00 AM the rst of the
month.

Operating Information
Power Supply:
We recommend using the supplied AC adapter with
one 9V battery installed as a back-up power source. This
ensures that your recording will not be interrupted when
there is a power failure.
To replace the back-up battery:
1. Keep unit plugged into the AC adapter while
changing the battery
2. Unscrew 4 screws in recessed holes on back
of the unit
3. Replace 9V battery
4. Replace back cover and 4 screws holding it
Telephone Jacks:
If you are looking at the unit from the front, and the
unit is in its upright position, the two RJ-11 telephone
jacks will be on the right side of the unit. The top jack
is used to connect the logger to the telephone line and
the bottom jack to an optional telephone using a standard
RJ-11 modular phone plug.
This unit does not require a dedicated phone line. It
will work with any analog phone line. It will not work as
an extension of a business telephone system.
Up to 12 units may be placed on a single phone line as
long as the total Ringer Equivalence Number on the line
does not exceed 5.0. The units should be programmed to
call out at different times,
Staggered by a minimum of 30 minute increments (see
gure 4). An explanation of Ringer Equivalence is
provided in the section labeled “The Dickson Warranty”.

General:
The FX430/435 logs data and formats it for display on a
faxed chart. At the end of the faxing interval period, it will
begin a new chart for the next period. The previous chart
will be faxed to the “FAX TO NUMBER” when the “NEXT
FAX TIME” occurs. If the transmission is unsuccessful, it
will retry every 10 minutes for up to 24 hours or until
the “SEND FAX” key is pressed. Pressing the “SEND FAX”
key will send the chart currently being built. If you want
to cancel the fax in retry mode, press “ON” and “ESC”
buttons.
While sending a fax, data logging is temporarily
interrupted. This will appear as a small gap in the graphed
data for as much time as it took to complete the fax
transmission.
