2. Programming the Reefdoser
The Reefdoser allows to control up to 4 dosing pumps independently. The pumps are switched on
and off in programmable intervals. The Reefdoser does not work with real time but with intervals.
For every channel (= dosing pump) 2 different intervals have to be programmed:
The cycle time and the on-time. The cycle time is the total duration of one interval (sum of on and
off-time).
Example: Every 12 hours trace elements shall be dosed for a period of 10 minutes. The cycle time
is then 12 hours, the on time 10 minutes. After dosing for 10 minutes, the unit switches off for 11
hrs and 50 minutes.
Programming:
-
Switch on: Insert the mains plug. Make sure that the voltage of your mains is the same
as indicated on the label at the back side of the unit. When the unit is connected to the
power supply, the display shows „duty" and flashes. Press the buttons „Adj" and „Set"
simultaneously to get into the working mode. If any intervals are already programmed,
the pumps start working now.
-
Switch into program mode: To reach the program mode, press the buttons „Set" and
„Enter" simultaneously. As long as you keep the buttons pressed, the display shows the
channel that can be programmed: „CH1" to „CH4". After 5 seconds, the display switches
to the next channel. If the number of the channel is shown that shall be programmed,
the 2 buttons (Set and Enter) are released.
-
Programming the cycle-time: If the program mode is reached, the cycle time can be
adjusted. After you release the buttons Set and Enter (see above), the display shows:
00.00. These 4 numbers are hours and minutes. Each number is set individually. Press
„Adj" button several times until you have reached the desired value. This value is saved
by pressing the „Set" button and the cursor jumps to the next number. In this way, all 4
numbers can be programmed. The cycle time can be varied from 99 hrs 59 minutes to 1
minute only. If all 4 numbers of the cycle time are programmed, you can save them by
pressing the „Enter" button.
-
Programming the on-time: After the cycle time has been saved, the display shows the
on-time. The on-time has 6 numbers, however, only 4 of them can be shown
simultaneously; 00.00. The first 4 numbers are hours and minutes. They are
programmed in the same way as the cycle time: Press the „Adj" button until the desired
value is reached and confirm by pressing „set". The cursor jumps to the next number. If
all 4 numbers (hours and minutes) are programmed, the display changes and shows
minutes and seconds. As the minutes are already programmed, the cursor jumps directly
rd
to the 3
number, the seconds. The seconds are programmed („adj" and confirmed by
„set"). The values are saved by pressing the button „Enter". The on-time has always to
be shorter than the cycle time. If, by mistake, the on-time is set longer than the cycle
time, the display will show error „err". The channel is now ready programmed. After
pressing the „Enter" button, the Reefdoser starts working and switches on the pump
(for the on-time).
-
Programming other channels: To program the next channel, press and hold again the 2
buttons „Set" and „Enter" simultaneously. Now channel 1 „CH1" is shown on the display.
After approx. 5 sec., the display switches to „CH2", etc. As soon as the desired channel is
displayed, both buttons are released and the channel can be programmed as described
for CH1.
-
Power failure and synchronisation: All programmed data are saved independently of the
power supply. If the unit is switched on again after a power failure or after removal of
the power plug, it will not start working again automatically. The display shows „duty"
and flashes. It starts only after pressing the buttons „Adj" and „Set" simultaneously (see
item 1.) The channels work synchronously then. This means they all start with their on-
time. The channels that are switched on are indicated by their green LED.
