HydroPower® RO XXL
Operation
4. OPERATION CONTROL BOX
4.1. Control box - Overview
The UNGER Control Unit provides a simple operation of the two water
pumps, which deliver the pure water and the RO filling unit, which fills
the tank with purified water.
LEFT FLOW = Controls the pump for the left hose reel.
RIGHT FLOW = Controls the pump for the right hose reel.
RO FILLING = Controls the filling of the tank with purified water.
With the remote controls the left and right pump can be controlled from
a distance and you can switch between “wash” and “rinse” mode.
The remote control works on a distance of max. 100m in open area. If
buildings or plants are between the operator and the trailer, the reach
can be reduced.
4.2. Operating the left/right flow
1. Switch on the desired pump (left/right) by pressing the UP-button
.
2. Adjust the desired water output on the control box using the UP/DOWN-buttons
.
• The controller also provides an indication of flow rate (range: 0-99).
• The difference between wash and rinse mode is set by default at
30
. This value can be changed
(see below “Rinse Speed Mode”)
• Default set speed:
30 (washing) = 60 (rinsing)
• Example-possible wash speed adjustment :
40 (washing) = 70 (rinsing)
3. If you press ENTER
again, you see the battery voltage. Example:
BAT
,
12.4
Note:
At 14,0 ithe battery is fully charged, at 10,5 it shuts off.
4. When you press ENTER
once more, you are back to the flow rate
FLO
5. To switch off the controller, press and hold ENTER
.
4.2.1 Remote Control
It’s also possible to use the remote control to switch the related pump (left or right) on/off or to change
between wash and rinse mode. The remote control allows you to change the flow from the place where you
are working (max. 100m in open areas).
WASH MODE
(to select a normal flowrate for standard cleaning):
• Push the W
button on the remote control
RINSE MODE
(to select a higher flowrate for rinsing the surface):
• Push the R
button on the remote control.
• ‘
RIN
’ appears in the control box display and the diaphragm pump delivers more flow boost.
The rinsing value is by default always 30 higher than the wash value, but max. 99.
(or according the set value in Rinse Speed Mode).
Please also note the channel
of each control for the case you
lose it. Example here: „Ch. 01“
Remote Control
On the backside of the remote
control you can read if it is for
the left or right hose reel.
Control Unit
Calibration Mode:
In calibration mode it is defined when the system shuts off at “dead end” situations (e.g. interrupted waterflow, air in the line etc.).
Pay atten-
tion:
The default setting of
79
should
NOT
be changed. A higher value could damage the system as it shuts off possibly to late. A lower value
could cause that the system shuts off too early.
•
When pushing both UP&DOWN buttons
, you are entering in the
CAL
mode (calibration) - if that happened accidentally go
back by pushing the ENTER button
button!
•
This is a WATER PUMP controller: it will not work with air in the system. Air could cause false dead-end detection.
•
Always prime your system before starting work.
•
Repeated false dead-end detection (
dE
) indicates that the
CAL
value should be increased (less sensitive). But don’t set the
CAL
value too high as this could cause damage to the pump.
•
There is as well an “AutoCalibration” function. Press UP+ENTER button
+
to enter the
CAL
mode, press DOWN
to start
the “AutoCal”-mode (
AUt
). After some seconds the calibration value will be displayed and has to be confirmed with ENTER
Rinse Speed Mode:
The rinse water flow is always in same relation higher than wash flow. Default setting value:
30
•
If you
push both UP&DOWN buttons
longer, you are entering the setting mode for the rinse speed.
•
You can change this value with the UP/DOWN buttons
. The entered number is added to the washing speed when you activate
rinsing. (Example: if you change value to 50: if wash is 40 then rinse is 90)
•
Return to previous mode with the ENTER button
.
•
‘
SET
’ is displayed now on the display to confirm the new value.
